Solar panels that you can drive, park, and walk on. They melt snow and... cut greenhouse gases by 75-percent?!!!
I remember, years ago, talking with friends, we were discussing the possibilities what if parking lots and roads were covered in solar panels.
And see, here is this couple from the US on Indiegogo pursuing their project which is actually doing it!!!
Have a look and you can still invest; 8 more days to go!
