I was out of the country for the past year. While I was away my father Neil designed and built a solar powered golf cart (in our case a work cart). I worked with him this summer installing electric at the Jefferson County Fair and it was amazing to see how effective the solar cart was. It was as fast as the gas powered carts, completely quiet, and was used for over 12 hours a day never needing a charge or any maintenance.
Neil making sure everyone knows he is solar powered.
Here is a link to an article the local paper wrote about the cart and his other solar projects.
We worked next to this guy for a bit. He had his own idea of what makes ideal transport.
