This year's <keyword id="20028513" type="General" weightage="20" keywordseo="Olympic-Games" source="keywords">Olympic Games</keyword> are all set to kick off on Friday, July 26! The Paris 2024 Opening Ceremony will unfold in a spectacular six-kilometre-long floating procession along the Seine River. Athletes will traverse Paris aboard 160 boats, culminating their journey at the Trocadero, all while the Eiffel Tower gleams with lights.<br /><br />A key highlight of the ceremony will be the arrival of the <keyword id="21323045" type="General" weightage="100" keywordseo="Olympic-flame" source="keywords">Olympic flame</keyword>, carried by the final torchbearer. Upon reaching the arena, the torchbearer will complete a lap before lighting the Olympic cauldron, marking the official commencement of the Games.<br /><br />But where does this iconic Olympic flame originate? Its creation involves a timeless ritual that bridges the ancient traditions of Greece with the modern Olympic Games.<br /><cmsannotation type="cmsannotation" annotationid="Olympia's timeless tradition: Igniting the flame of peace and friendship" comment="subhead" text="Olympia's timeless tradition: Igniting the flame of peace and friendship"><span data-til="noop">Olympia's timeless tradition: Igniting the flame of peace and friendship</span></cmsannotation><br />To this day, the Olympic flame lighting ceremony takes place at Olympia, Greece, the birthplace of the Games. This ritual, conducted months before the <keyword id="19933819" type="General" weightage="20" keywordseo="Olympics" source="keywords">Olympics</keyword>, symbolises peace and international friendship.<br /><br />The Olympic flame's origins date back to ancient Greece, where a sacred fire was maintained at the altar of Hestia, the goddess of the hearth. This fire was ignited using the sun's rays, focused through a parabolic mirror—a method still employed today.<br /><br />During this ceremony, a group of women known as the Vestal Virgins performs a ritual at the <keyword id="22541691" type="General" weightage="20" keywordseo="temple-of-hera" source="keywords">Temple of Hera</keyword>.

If weather conditions are adverse, a backup flame from a previous rehearsal may be used.<br /><br /><strong>Symbolic acts</strong>: Once ignited, the flame is placed in an urn and handed to the first torchbearer, usually a Greek athlete.

He ultimately sold his shares for a loss, according to brokerage statements viewed by Business Insider.</p><p>"I found a lot of Reddit users, particularly on the Wall Street Bets community, come up with all this sort of diligence and research about GameStop. Then I kind of went down that rabbit hole," he said of his first foray into GameStop. "Then the initial dump happened, so to speak, from the $300 range back down to the $100 range, and I was needless to say very distraught. It was just a crushing blow to my spirit and everything."</p><p>Never did it occur to Dan to sell his shares when GameStop peaked. The prospect that the stock would soar even higher was too intoxicating, he says.</p><p>"I drank the Kool-Aid, so to speak, of the Reddit community and the GameStop zealots," he said. "The FOMO or the fear of missing out was so high that at the time there was no part of me that even considered selling.

Still, he couldn't help himself from scooping up more GameStop shares when the stock rocketed higher this year.</p><p>"I dabbled a little bit with this current uptrend, certainly nowhere near the levels I was putting in before. I made a little bit on it, then I lost a little bit on it, so it's just been kind of a wash," he said, adding that he was mostly drawn to the latest rally out of "amusement."</p><h2 id="12608954-744d-4fce-9d43-461833335e4a">Seeking financial freedom</h2><p>Brian, another retail trader who invested in GameStop in 2020, says he was also drawn back in amid this year's RoaringKitty-fueled rally.</p><p>"When he posted, I kind of dabbled into it," he told BI. "You see all the hype around it, and then you see the price just shoot up. It's hard not to want to just jump in."</p><p>The allure of GameStop stock has been the potential for a big, quick payday, Brian added, and plowing cash into a meme stock is like buying a lotto ticket for a chance at financial independence.</p><p>"[They] could essentially just make you financially free. You never have to work," he said. "I live in the Bay area of California, so it's very hard out here if you don't have a very well-paid job or if you don't have a dual income … So I was looking for something that could gain me the freedom to not have to work and grind it out every day."</p><p>Others echoed that sentiment, noting that the chance to hit it big is too enticing to sit it out as the stock starts going parabolic.</p><p>"I've been unemployed since November and I've been struggling to find work," said Zaine, another retail trader.</p><p>He never traded meme stocks but has bet against risky assets during the pandemic. His portfolio ballooned to as much as $75,000 before plunging to near zero, screenshots of his brokerage account show.</p><p>"You go to these outlets thinking, I can just make a little bit of money on the side to kind of just survive," he said. "And it ends up being this snowball effect that, if you don't look at yourself in the mirror, you can really end up losing everything."</p>

These retail traders lost big in the first meme stock episode. Here's why they won't stop betting on GameStop.

But few people on Earth have ever used as bizarre or overkill a method as devised by a Cold War physicist: the explosion of a nuclear bomb.</p><p>On Sunday, a <a href="https://www.reddit.com/r/todayilearned/comments/cs5e2k/til_that_physicist_ted_taylor_was_the_first/" target="_blank" rel="noopener">thread</a> in Reddit's popular "r/TodayILearned" community mentioned the <a href="http://awesci.com/nuclear-bomb-cigarette-lighter/" target="_blank" rel="noopener">story</a> of how theoretical physicist Ted Taylor used the blinding flash of an atomic explosion to light a cigarette in 1952.</p><p>Records of "atomic cigarette lighter" events aren't exactly robust, but it appears Taylor was the first to come up with the idea. That's according to author Richard L. Miller, whose 1999 book "<a href="https://www.amazon.com/Under-Cloud-Decades-Nuclear-Testing/dp/1881043053" target="_blank" rel="noopener">Under the Cloud: The Decades of Nuclear Testing</a>" chronicled the event <a href="https://books.google.com/books?id=adI-6jRDipgC&amp;lpg=PP1&amp;pg=PA154#v=onepage&amp;q&amp;f=false" target="_blank" rel="noopener">in detail</a>.</p><p>Taylor apparently lit his cigarette during a Operation Tumbler-Snapper, which was a series of test blasts orchestrated by the US military at the Nevada Test Site. The operation happened in the throes of the Korean War - a conflict in which President Harry Truman considered dropping the bomb (<a href="https://www.airspacemag.com/military-aviation/how-korean-war-almost-went-nuclear-180955324/" target="_blank" rel="noopener">again</a>).</p><p><em><strong>Read more</strong>: <a href="https://www.businessinsider.com/new-nuclear-blast-videos-2017-3">Hundreds of never-before-seen nuclear blast videos show terrifying explosions in the ocean and Nevada desert</a></em></p><p>Government officials codenamed the test explosion or shot in question "George" because it was the seventh in a series (and "G" is the seventh letter of the alphabet). Its purpose wasn't to light up a smoke, of course: Military researchers placed a roughly 3,000-pound nuclear bomb design known as the Mark 5 atop a 30o-foot-tall tower to try out a new blast-triggering technology, according to <a href="https://nuclearweaponarchive.org/Usa/Tests/Tumblers.html" target="_blank" rel="noopener">the Nuclear Weapons Archive</a>.</p><p>The day before the test shot, Taylor apparently found a spare parabolic (cup-shaped) mirror, according to Miller's book, and set it up in the facility's control building ahead of time. Taylor knew exactly where to place the mirror so that it'd gather light from the test explosion - which would release <a href="https://www.businessinsider.com/nukemap-nuclear-blast-estimates-radioactive-fallout-shelters-2018-10">gobs of thermal energy</a> - and focus it on a particular spot.</p><p>Next, Taylor hung a Pall Mall cigarette on a wire so that its tip would float directly in front of the focused light beam. The arrangement wasn't too different in principle from holding out a magnifying glass to concentrate sunlight on a piece of paper and light it on fire.</p><p>On June 1, 1952, Taylor and other weapons experts huddled into the bunker-like control building near Area 3 of the <a href="https://www.globalsecurity.org/wmd/facility/nts-areas-1.htm" target="_blank" rel="noopener">Yucca Flats</a> weapons test basin in Nevada. Then they set off the bomb.</p><p>"In a second or so the concentrated, focused light from the weapon ignited the tip of the cigarette. He had made the world's first atomic cigarette lighter," Miller wrote of Taylor's setup.</p><h2>'It is a form of patting the bomb'</h2><p>Taylor's nuclear-age antics likely did not stop with him.</p><p>Martin Pfeiffer, an anthropologist who researches humanity's relationship with nuclear weapons (and who frequently <a href="https://www.patreon.com/nuclearanthro" target="_blank" rel="noopener">forces the release of documents</a> related to the bomb) <a href="https://twitter.com/NuclearAnthro/status/1163216566151815168" target="_blank" rel="noopener">tweeted</a> that a 1955 Department of Defense film appears to show the concept in action.</p><p>About 19 minutes into the half-hour <a href="https://www.youtube.com/watch?v=_eD1mro_xq8" target="_blank" rel="noopener">movie</a>, titled "Operation Teapot Military Effects Studies," a narrator describes how parabolic mirrors were used to concentrate the light-based energy from nuclear explosions on samples of ceramics.</p><p>In the clip, a person's hand holds the tip of a cigarette in a beam of focused light, causing it to smoke and ignite:</p><p>Although this looks like another cigarette being lit by a nuclear weapon, that's unlikely.</p><p>There's no blinding flash - a telltale effect of a nuclear explosion - and the length of time the light beam stays on-screen is far too long as well. The person being filmed probably just held out his cigarette for the videographer so as to demonstrate the concept of a parabolic mirror focusing would-be bomb energy.</p><p>Still, it's not hard to imagine the story of Taylor's feat spreading among his colleagues over many years and hundreds of above-ground US nuclear test shots. A few others probably tried it themselves.</p><p>In any case, Pfeiffer isn't enamored by such stunts.</p><p>"Lighting a cigarette with a nuclear weapon ... is at least in part an effort of domestication of nuclear weapons through a performance articulating it to a most quotidian act of cigarette lighting," he <a href="https://twitter.com/NuclearAnthro/status/1163216566151815168" target="_blank" rel="noopener">tweeted</a>. "It is a form of patting the bomb."</p><p>That is to say: The act risks trivializing nuclear weapons, which can and have inflicted mass death and destruction. The US nuclear bombings of Hiroshima and Nagasaki in 1945, for example, led to <a href="http://www.aasc.ucla.edu/cab/200708230009.html" target="_blank" rel="noopener">approximately 150,000 casualties</a> - and decades of suffering for many who survived the attacks.</p><p>Today, above-ground nuclear testing is mostly banned worldwide, since it can spread <a href="https://www.businessinsider.com/survive-nuclear-explosion-go-inside-shelter-no-windows-2018-1">radioactive fallout</a>, <a href="https://www.businessinsider.com/nukes-electromagnetic-pulse-electronics-2017-5">mess with electronics</a>, be mistaken for an act of war, and more. But US-Russia relations have deteriorated to the point that each nation is racing to develop and test new nuclear armaments.</p><p>The Comprehensive Nuclear Test-Ban Treaty, or <a href="https://www.ctbto.org/specials/who-we-are/" target="_blank" rel="noopener">CTBT</a>, endeavors to ban nuclear explosions "by everyone, everywhere: on the Earth's surface, in the atmosphere, underwater, and underground." Russia has <a href="https://www.ctbto.org/the-treaty/status-of-signature-and-ratification/" target="_blank" rel="noopener">signed and ratified the treaty</a>, but eight other nations have yet to complete both steps and bring it into effect.</p><p>The United States signed on to the CTBT in 1996, but Congress has <a href="https://www.businessinsider.com/nuclear-test-ban-treaty-countries-2015-10">yet to ratify the nation's participation</a> in the agreement. There are also nearly <a href="https://www.businessinsider.com/nuclear-weapons-stockpiles-world-map-2017-8">15,000 nuclear weapons</a> in existence today, which means the atomic cigarette lighter trick could, almost certainly for worse, be tried again.</p><div><div style="position:relative; padding-bottom:calc(64.60% + 44px)"><iframe src="https://gfycat.com/ifr/ImprobableTheseJay" frameborder="0" scrolling="no" width="100%" height="100%" style="position:absolute;top:0;left:0;" allowfullscreen=""></iframe></div></div>    <div class="margin-top">        <h3>NOW WATCH: <a href="https://www.businessinsider.com/godzilla-wwii-japan-nuclear-bombs-monster-kaiju-fishing-boat-2019-6">The true story you probably don't know behind 'Godzilla' came from the devastation after Hiroshima and Nagasaki bombings</a></h3>        <div>            <iframe class="bijwplayerclass" data-player="jwplayer" src="https://content.jwplatform.com/players/hvyPgRMg-CEZHWCBG.html" width="100%" height="100%" frameborder="0" scrolling="auto" style="margin:0px;" allowfullscreen=""></iframe><script>function receiveMessage(event){ console.log(event.data.fullscreen); Android.fullscreen(event.data.fullscreen); }window.addEventListener("message", receiveMessage, false);</script>        </div>    </div>

Yes, a physicist once lit his cigarette with a nuclear bomb explosion. Here's how it worked.

Their big, longing eyes more closely resemble WALL-E than actual spiders - a design consideration Dalloro says was crucial.</p><p><span>"Based on the results from one of our test groups, we decided to add an eyeglass to the robots to soften its appearance," Dalloro says, a change that even <a href="http://www.techinsider.io/how-pixar-uses-lighting-to-tell-breathtaking-stories-2015-12">the folks at Pixar say they had to make</a> when creating WALL-E's oddly endearing goggles.</span></p><p><div class="KonaFilter image-container display-table"><div><div class="image on-image"><img src="https://static-ssl.businessinsider.com/image/572108acdd0895167d8b470c-1000-667/9n9a2845.jpg" alt="3D printing spider robot" data-mce-source="Siemens" /><p class="source"><span>Siemens</span></p></div><p></p></div></div>Each SiSpi works in tandem with the other robots according to their specific programming. The "eyes" on the SiSpi face are actually laser scanners, which read the surrounding area and talk to the robot's extruder arms about where to build.</p><p>Based on software Dalloro and his team created, each of the robots can then work on a specific "box" of space without getting in the other robots' way.</p><p>Dalloro admits that it's too early to tell how many robots would be needed to construct a car or a fuselage, or how long an entire build might take. What the team does know is that even robot spiders get tired. When one SiSpi's battery is running low, which happens after about two hours, it'll alert a nearby team member that it's going to charge back up. The fully-charged spider will then take over the duties of the first spider until it returns at a full charge.</p><p><div class="KonaFilter image-container display-table"><div><div class="image on-image"><img src="https://static-ssl.businessinsider.com/image/572108acdd0895167d8b470d-889-667/960a1470.jpg" alt="3D printing robot spider" data-mce-source="Siemens" /><p class="source"><span>Siemens</span></p></div><p></p></div></div>Right now, the only material SiSpis can handle is a mixture of corn starch and sugarcane known as poly lactic acid.

<p>Until today, he was also one of the <a href="http://www.businessinsider.com/category/hugh-hendry">more bearish managers too</a>.</p>
<p>"I can no longer say I am <keyword id="46699" type="UNKNOWN" weightage="60" keywordseo="bearish">bearish</keyword>," said <a href="http://www.investmentweek.co.uk/investment-week/news/2308814/i-cant-look-at-myself-in-the-mirror-hendry-on-why-hes-turned-bullish">Hendry today according to InvestmentWeek</a>. "When markets become parabolic, the people who exist within them are trend followers, because the guys who are qualitative have got taken out."</p>
<p>Speaking at the Harrington Cooper conference, Hendry argued that an ongoing currency war between the U.S. and China will continue to force the Federal Reserve to keep monetary policy loose and easy.</p>
<p>"I may be providing a public utility here, as the last bear to capitulate," he said. "You are well within your rights to say 'sell'. The S&amp;P 500 is up 30% over the past year: I wish I had thought this last year."</p>
<p>Hendry sounded pretty crestfallen. Here's more from <a href="http://www.investmentweek.co.uk/investment-week/news/2308814/i-cant-look-at-myself-in-the-mirror-hendry-on-why-hes-turned-bullish">InvestmentWeek</a>:</p>

<p style="padding-left: 30px;">"I cannot look at myself in the mirror; everything I have believed in I have had to reject. This environment only makes sense through the prism of trends."</p>
<p>As Hendry said, he is not the first bear to "warn" that stocks are likely to go much higher from here. Here's a round up of some recent quotes we've heard from the long-time bears:</p>
<div>
<p style="padding-left: 30px;"><a href="http://www.hussmanfunds.com/wmc/wmc131111.htm"><strong>John Hussman</strong></a>: "...we should neither expect, rely or be shocked by a further blowoff..."</p>

<p style="padding-left: 30px;"><a href="http://www.businessinsider.com/richard-russell-upside-explosion-in-stocks-2013-11"><strong>Richard Russell</strong></a>: "<span class="style_3">I continue to think that this bull market will end in an upside explosion.</span>"</p>
<p style="padding-left: 30px;"><strong><a href="http://www.businessinsider.com/stock-market-crash-warning-signs-2013-11">Bob Janjuah, Nomura</a></strong>: "I still see end Q4 2013, through to end Q1 2014, as the window in which we see a significant risk-on top before giving way, over the last three quarters of 2014 and through 2015, to what could be a 25% to 50% sell-off in global stock markets."</p>
<p>Is there no one else?</p>

HUGH HENDRY: 'I Can No Longer Say I Am Bearish'

The pair developed a thermal treatment system for human feces as a research project and later entered their work into <a href="http://startupchile.org/">Start-Up Chile</a>, a business accelerator in South America.</p><p>While in Chile, they explored the sanitation space, encountering several startling statistics about developing countries, including the fact that 90% of waste is disposed of without treatment and that <a href="http://www.who.int/mediacentre/factsheets/fs330/en/">diarrhoeal disease is the second-leading cause of death</a> of children under the age of 5. From there, Foote and Woods decided to go all in with the business.</p><p><div class="KonaFilter image-container display-table float_right"><div><div class="image on-image"><img src="https://static-ssl.businessinsider.com/image/57585eca52bcd023008c7d0c-2400/sanivation blue box storefront.jpg" alt="Sanivation Blue Box storefront" data-mce-source="Courtesy of Sanivation" /><p class="source"><span>Courtesy of Sanivation</span></p><p class="caption">The storefront for blue box toilets.</p></div><p></p></div></div>Sanivation set up shop in Naivasha, Kenya, in 2013 with Foote as CEO and Woods as chief technology officer. Today, the company serves 650 people in the community there.</p><p>Foote and Woods knew from the beginning that to succeed they'd need to cover the entire system from start to finish. The lack of existing infrastructure in some parts of Kenya means that providing toilets or a treatment system wouldn't make much of a difference; both must exist to effect systemic change.</p><p>So instead of providing one component of the waste-treatment business, Sanivation operates an end-to-end service. It installs private, container-based toilets in homes, and they are maintained for a $7 monthly fee. The waste collected from the toilets is taken to a processing plant, where it's turned into fuel briquettes that work as an alternative to charcoal. This full-circle model takes a necessary system and elevates it into something sustainable and useful.</p><p>"People always joke that we're running not one business but 10 businesses," Woods says. "As a startup, it's complicated, it's logistically difficult. But we haven't found anyone to reliably source any one component of this to. Right now, if we want it done right, we have to do it ourselves."</p><h2>Getting toilets into homes</h2><p>The concept of in-home toilets was a hard sell to locals, much less an entire system.</p><p>"How do you market something that people feel uncomfortable talking about?" Woods says.</p><p>In Naivasha, where outdoor pit latrines are the norm, the mention of an in-home toilet led many to immediately picture an open latrine inside their home - not a preferable alternative to the outdoor version. So Sanivation branded their version as "blue boxes" to dispel the negative connotations potential people had with the word "toilet."</p><p><div class="KonaFilter image-container display-table"><div><div class="image on-image"><img src="https://static-ssl.businessinsider.com/image/57585dbf52bcd029008c7bdb-2400/burning briquettes_cosanivation.jpg" alt="Burning briquettes_CoSanivation" data-mce-source="Courtesy of Sanivation" /><p class="source"><span>Courtesy of Sanivation</span></p><p class="caption">Burning briquettes.</p></div><p></p></div></div>On top of that, Sanivation had to convince clients, many of whom can't count on a steady monthly paycheck, that paying the monthly fee for the toilet was a worthwhile expense.</p><p>Training customer-service representatives and maintaining communication with clients proved to be another challenge, especially once the team realized that many homes in Naivasha don't have addresses. Undeterred, they developed an address system themselves.</p><p>In the end, these bumps in the road, and a host of others, helped Sanivation improve its product. The company thrives on client feedback, constantly seeking constructive criticism directly from their customers.</p><p>"If we're not doing a good job, our client is not going to pay the next month," Foote explains. "By being beholden to our clients and delivering quality services to them, we always learn that keeping good, open communication channels is really important."</p><h2><strong>From feces to fuel: how it works<br /></strong></h2><p>No existing toilet system meant that no existing treatment plant existed in Naivasha, so Sanivation designed and built one from the ground up. Led by Woods as CTO, the team developed a parabolic mirror treatment system themselves, harnessing the natural energy from the sun to heat up waste and kill germs.</p><p><div class="KonaFilter image-container display-table float_right"><div><div class="image on-image"><img src="https://static-ssl.businessinsider.com/image/57585d1a52bcd05c658c79d3-1224/briquette manufacturing.jpg" alt="Briquette manufacturing" data-mce-source="Courtesy of Sanivation" /><p class="source"><span>Courtesy of Sanivation</span></p><p class="caption">Manufacturing briquettes.</p></div><p></p></div></div>Sanivation combines two waste streams in a metal bucket - human excrement and carbonized agricultural biomass waste, which comes from things like sugarcane gas, corn cobs, rose farms, and rice husks - and heats it to a temperature that neutralizes harmful pathogens and allows the waste to be transformed into a briquette of fuel.</p><p>The briquettes have been a hit with local businesses, which purchase them directly from the Sanivation team.</p><p>"Our charcoal briquettes outperform traditional charcoal," Foote says. "So we're actually selling them at a higher price than traditional charcoal per kilogram, <em>and</em> we're saving our clients money because they burn longer and have less smoke."</p><p>Sanivation sells 7,000 kilograms, or 15,400 pounds, of the alternative fuel each month and consistently empties its stock.</p><p>"We need more poop to be able to keep up with demand," Woods says.</p><p>The entire treatment process demonstrates a core aspect of Sanivation's business model: relentless innovation. With no outside infrastructure to rely on, Woods and Foote must adapt and change almost daily to meet needs and advance their mission.</p><h2><strong>Looking to the future</strong></h2><p>Going forward, Sanivation's biggest goal is also its biggest hurdle: scaling the company.</p><p>Sanivation operates 100 toilets in Naivasha and plans to expand to more than 500 by the end of 2016. The company is also working with refugee camps to build customized systems and train residents to operate them on their own.</p><p><div class="KonaFilter image-container display-table"><div><div class="image on-image"><img src="https://static-ssl.businessinsider.com/image/5758602a9105844e018c7ae4-2400/sanivation_tour of bluebox.jpg" alt="Sanivation_tour of BlueBox" data-mce-source="Courtesy of Sanivation" /><p class="source"><span>Courtesy of Sanivation</span></p><p class="caption">Sanivation cofounder Foote explains the blue box toilets.</p></div><p></p></div></div>Though a few other businesses are attempting similar container-based sanitation systems, none have reached a large scale yet, which leaves the space open for innovation and growth.</p><p>Woods says the company is going to have to change to be able to reach the scale it wants.</p><p>Sanivation may still be small, but it's already affecting people's lives. Foote recalls an older customer coming up to him one day and bending over with her hands pressed together in a salute of gratitude.</p><p>"You could just see that the toilet had so much more impact than as a public-health thing," he says.

<p>This year, farmers in California's Central Valley will likely receive no water through the federal irrigation program, a network of reservoirs, rivers, and canals that is normally replenished yearly by ice melt from the Sierra mountains.</p>
<p>Crippling water shortages have made desalination technology more attractive, including a startup, <a href="http://waterfx.co/" target="_blank">WaterFX</a>, that uses the sun to produce heat. The heat separates salt and water through evaporation.</p>
<p>WaterFX has fewer environmental repercussions than traditional methods of desalination that rely on fossil fuels to generate electricity.</p>
<p>The technology could not have come at a better time.</p>
<p><strong>No end in sight</strong></p>
<p>During a drought-free year, the federally run Central Valley Project provides enough water to <a href="https://www.usbr.gov/projects/Project.jsp?proj_Name=Central+Valley+Project" target="_blank">irrigate 3 million acres of agricultural land</a>. Last year, farmers only received 20% of their allotment. </p>
<p><span style="font-size: 15px; line-height: 1.5em;">The lack of water is not just worrying for growers. It affects all people who eat food. </span><a href="http://www.nytimes.com/2012/10/14/magazine/californias-central-valley-land-of-a-billion-vegetables.html?hp&amp;_r=0" target="_blank">One third of the nation's produce is grown in the Central Valley</a><span style="font-size: 15px; line-height: 1.5em;"> - composed of Sacramento Valley in the north and San Joaquin Valley in the south - and the deep water cuts mean that </span><a href="http://www.latimes.com/science/sciencenow/la-sci-sn-drought-cvp-20140221,0,3521779.story#axzz2vWnC8jiE" target="_blank">more than half a million acres of crop land</a><span style="font-size: 15px; line-height: 1.5em;"> will be left unplanted.</span></p>
<p><span style="font-size: 15px; line-height: 1.5em;">Some scientists predict </span><a href="http://www.businessinsider.com/california-drought-could-last-for-a-century-2014-3">California's drought could last as long as a century</a><span style="font-size: 15px; line-height: 1.5em;">. Going forward, the state is going to need a substantial water supply that doesn't rely on the aqueduct system, says Aaron Mandell, WaterFX chairman and founder. </span></p>
<p>However, in order to counter California's water problems, the push must be toward renewable desalination plants rather than fossil-fuel dependent facilities that further contribute to climate change.</p>
<p><strong>Making freshwater from sunshine</strong></p>
<p>In WaterFX's system, a solar trough, which looks like a jumbo-sized curved mirror, collects energy from the sun's rays and transfers that heat to a pipe filled with mineral oil. The mineral oil feeds the heat into a system that evaporates the salty water being treated. Steam is produced, which condenses into pure liquid water. The remaining salt solidifies and can be removed, says Mandell. That salts can be used in other industries as building materials, metals, or fertilizers.</p>
<p>In order to operate continuously, the solar trough is very large so that it collects extra heat during the day. The energy is stored and used to run the system at night when the sun isn't shining.</p>
<p>By using sun as the fuel source, WaterFX uses roughly one-fifth of the electricity consumed by traditional desalination plants, according to Mandell. Less electricity means lower operating costs. With conventional desalination, electricity makes up 50-60% of the water costs, says Mandell. A typical desalination plant in San Diego operates at about $900 per acre-foot, while it costs around $450 to produce an acre-foot of water with WaterFX. (An acre-foot is 325,000 gallons, or the amount of water it takes to cover an acre at a depth of one foot).</p>
<p><div class="KonaFilter image-container display-table float_right"><div><div class="image"><img src="https://static-ssl.businessinsider.com/image/531e1c9b6bb3f72565206f6f-1067-800/waterfx-3.jpg" border="0" alt="WaterFX" /><p class="source"><span>WaterFX</span></p><p class="caption">WaterFX chairman and founder, Aaron Mandell.</p></div><p></p></div></div>"Solar desalination is still a very immature technology so there's a quite a bit of room to drive that cost down even further," said Mandell.</p>
<p>Many desalination facilities, including the $1 billion <a href="http://carlsbaddesal.com/" target="_blank">Carlsbad plant</a> set to open in 2016, use a process known as reverse osmosis that forces seawater through billions of tiny holes that filter out salt and other impurities. This method can produce fresh water on a large scale, but has economic and environmental drawbacks. It uses an immense amount of electricity and only about half of the seawater that goes into the system comes out as clean water. The remaining half is dumped back into the ocean as salty brine where it can be harmful to marine plants and animals.</p>
<p>By contrast, Mandell says that WaterFX has a 93% recovery rate, meaning that for every 100 gallons of water that goes in, 93 gallons of usable water are spit out.</p>
<p>WaterFX also helps solve an issue that has long plagued irrigated land. Soils in the arid west of San Joaquin Valley naturally contain a lot of salt as well as high concentrations of metals, like selenium, <a href="http://www.bay.org/assets/drainage.pdf" target="_blank">which can be toxic to humans and wildlife</a>. When the soil is irrigated, the salt, selenium, and other elements become concentrated in the drainage water that collects in a system of drains and pumps under the crops. In the past, harmful drainage water might have been <a href="http://www.c-win.org/poisoned-lands-polluted-water.html" target="_blank">discharged into rivers, wetlands, and aquifers</a> in the San Joaquin Valley. Now, that otherwise unusable water can be diverted to WaterFX and turned into irrigation water again.</p>
<p><strong>The first test</strong></p>
<p>The Panoche Water District in Central Valley is home to the first demonstration plant, a 6,500-square foot system that is capable of producing around 10 gallons of freshwater a minute, or roughly 14,000 of freshwater each day.</p>
<p>When the demonstration plant is operating in commercial mode, running 24 hours a day, it can put out 25 to 30 gallons of freshwater a minute, says Mandell.</p>
<p><div class="KonaFilter image-container display-table float_right"><div><div class="image"><img src="https://static-ssl.businessinsider.com/image/531f222b6bb3f7970328e9c7-1200-800/12055092376_1d115e811a_h.jpg" border="0" alt="WaterFX" /><p class="source"><span>WaterFX</span></p></div><p></p></div></div></p>
<p>The pilot project, funded by the California Department of Water Resources, will hopefully prove that the WaterFX system is more reliable (it doesn't depend on the Sierra snowpack) and affordable than other freshwater sources.</p>
<p>The water that's being treated by the pilot plant streams in from a canal that collects salty drainage water from around 200 farms in the area and brings it to a single location. In the pilot phase, the clean water that's produced is blended back in with the drainage water, but a commercial plant would send the water back to farmers through a series of canals that are already in place.</p>
<p>Additionally, small-scale systems could be used by individual farmers on site to recycle their own waste water.</p>
<p><strong>A bright future</strong></p>
<p>WaterFX is not the first company to experiment with solar desalination. The Sahara Forest project in Qatar and an Australian company called <a href="http://www.sundropfarms.com/about/" target="_blank">Sundrop Farms</a> are using the technology to grow food in greenhouses. But this is the first time a company has focused on using the sun's energy "to produce a scalable, long-term water supply," Mandell said.</p>
<p>The goal is to eventually be able to treat salty groundwater in addition to drainage water.</p>
<p>The immediate next step for WaterFX is to expand operations in Panoche to produce 2 million gallons of water per day. "From there it's about laying out a pathway for replicating this model all up and down the Central Valley," Mandell said. "We're trying to put a plan in place so that by 2020, we may be in a position to wean ourselves off the aqueduct system entirely."</p>
