Cars powered solely by solar energy? Sure…but with a very big “but”
Lately, I’m seeing a lot of cases where solar power is posited as the energy solution for “everything.” And why not? It’s free and ubiquitous, and it feels good to say you are using it. I recently read a column by someone (sorry, I couldn’t find it afterward) about the easy practicality of cars powered […]
