A few questions for ya:

• How do they get internet, cellular modem?
• What kind of theft prevention is in place? It's pretty easy to cut through a shipping container wall with the right tools, that's a lot of value a thief could easily grab in under 1 hour at night.
• What happens if they are shut down in cold weather, how do you pre-heat them prior to re-start? How do you prevent them from getting too cold during a shut-down?

Pretty cool tho.
Thx
