These Google employees are using high-tech, dirt-free shipping containers to grow organic herbs

Google's Mountain View Googleplex headquarters is famous for feeding its nearly 20,000 employees free breakfast, lunch, and dinner.

Feeding a small city of employees is a huge undertaking. There's an entire "Google Food" team that staffs more than 185 cafes globally and serves over 108,000 meals each day, with about 30 cafes at the Mountain View Googleplex headquarters alone.

The idea is to nourish employees with food that energize them, not carby low-nutrition foods that bring on afternoon lethargy.

And, because this is Google, the Food Team doesn't just buy and cook the food. They also run programs to grow food in sustainable, high-tech ways. Which means that Google has on its payroll all kinds of people involved with the cutting edge of organic gardening and food.

One such program is called "Farm to Table." Google has a lot of gardens, but this program looks for ways to educate people about the food industry. One highlight of that program is a shipping container at the Googleplex called the Leafy Green Machine. Take a look:
