This week: Silicon Valley is freaking out over audio tech

If you needed any more proof that 2021 is the year of audio, have a listen to NASA's latest release, direct from Mars' Jezero Crater! The 60-second audio clip, captured by the Perseverance Rover, is the first-ever recording of sounds from the surface of another planet. The sound is basically just Martian wind (what did you expect to hear?), but it's a pretty amazing thing to hear.

Closer to Earth, audio tech is booming.

Streaming music company Spotify held a big presser Monday to unveil a bunch of new bells and whistles for its audio "creators."

• These include new tools for podcasters to integrate polls and other interactive elements into their programs, and features for musicians to personalize their Spotify offerings. Also in the works is a new Spotify audio marketplace to let advertisers access different listening audiences, from podcast lovers to metalheads.
• Sadly, as far as I can tell, there was no update on the Spotify product I'm most excited for: Car Thing, the hardware audio player which appears to be back from the dead and potentially nearing a commercial rollout.

Unless you've been living on Mars, you've probably heard of Clubhouse by now.

Insider columnist Adam Lashinsky has a smart take on the audio-based social network here. And Melia Russell has written a great story chronicling how the founders of Clubhouse rebounded from failure to a $1 billion valuation.

After weeks of positive press coverage thanks to cameos by Elon Musk and Mark Zuckerberg, Clubhouse has hit a patch of negative press due to security lapses and revelations about its ties to China.

• One of the takeaways seems to be a not-too-surprising recommendation: assume you're being recorded when you have a discussion on Clubhouse.
• More surprising is the company's use of Shanghai company Agora for its back-end audio processing, as researchers discovered.
• At a time when the US and China are embroiled in a tech cold war, and the protection of user data from the Chinese government has become a hot button issue (remember that whole thing about TikTok?), it's odd that Clubhouse, and its sophisticated financial backers, chose to rely on a firm based in China for part of its back-end infrastructure.

Meanwhile, the attack of the Clubhouse clones is already underway, with Facebook, Twitter and Mark Cuban all racing to develop their own audio-based social networking services. And Clubhouse itself, which now has 10 million weekly users of its iPhone app according to MSNBC, may be getting closer to releasing an Android-version of the app.

Gen Z goes VC

You need to be 35 years old to be President of the US according to the Constitution. But no such rule governs when a person can become a venture capital investor. And Gen Z - those youngsters born between 1995 and 2010 - are already getting into the VC game, as Insider's Margaux MacColl reports.

The VCs on the list range in age from 19 to 25 and followed a variety of paths to venture capital, from launching their own startups to working in finance. All are incredibly ambitious and have leveraged social media in innovative ways.

Quote of the week:

"Give my regards to your puppet master"

- Tesla CEO Elon Musk, responding to a Washington Post article about how his various endeavors, including running a space exploration company and frequent travel, may be affecting Tesla's operations. Musk's comment appeared to be a jab at arch-rival Jeff Bezos, who owns the Washington Post and whose Blue Origin space company competes with Musk's SpaceX.

Snapshot: How to get your EV hitched

Towing a trailer with an electric car has an obvious drawback: all that extra weight will drain your car's battery.

The sleek-looking, aluminum trailer pictured below is specially designed for use with Teslas and other EVs to solve that problem. According to Polydrops, the maker of the P17A trailer, a 2018 Model 3 Tesla was able to tow the 1,200-pound trailer for 245 miles on one charge during its tests.

The trailer can accommodate a full size mattress, and has a built-in battery and rooftop solar panels that can supply 260 to 520-watts of solar energy - enough to power the interior lights, heater and air conditioner, power outlets and optional fridge for up to six nights off the grid.

If you splurge for all the options, the P17A will run you about $36,000 - about the cost of buying another Tesla.
