No energy is "clean".
We cannot live on this planet AND have no impact on it...
But there are better ways and worse ways...
The best type of energy is energy that is not wasted.
reducing the weight of vehicles is a good idea - the best way in my case is to
reduce my own weight. LOL
BTW I`ve got a lawn mower that is powered by lead-gel batteries. I use small
solar panels to recharge the batteries during the week and then at the weekend
I cut the grass with solar power.
Not really cost efficient etc., but it was fun to set it all up. And it makes
other people think about the possibilities!
One question: If the python is PUSHED by a motor e.g. on a BOB-trailer - won`t
that influence steering and wheel flop negatively?
