We had little electric trucks and vans for putting around the naval base I worked on. They were converted trucks made in China. The vans had solar panels on the roof to help charge them. They didn't have AC, and it's hot as Hell here in Floriduh. So, we parked the solar panel equipped vans hugging the north side of the building... so they'd be in the shade... and stay relatively cool inside.

When they told us were were getting a Vantage for our building at work, I said "*** that, let's get a DB9 instead."
