The Constitution is broken.

I am not really going into the political aspect of it. I am just saying that it could work for some people while it doesn't work for others. For me, it just comes down to the cost of purchasing and insuring another vehicle vs. the fuel and maintenance savings. Just a simple cost problem, nothing to do with environmentalism and politics. That's something we can all connect with.

No idea how quickly (if ever) it will get into mass production.
If workable, I wonder if the process could be used on cars too? |
I am no master of thermodynamics, but the concept doesn't sound good to me.
While the nanogenerator itself isn't BS, it seems like the general concepts violate the law of thermodynamics.
If it runs on friction, then it runs on heat. That's what friction generates. But converting heat to pretty much any other kind of energy(mechanical, electrical, etc.) can't be very efficient due to thermodynamic laws. So at best, you recover a bit of loss from that friction and turn it into useful electrical energy, but you won't be able to sustain the cruising from just that.
There are lots of environmentalist ideas that sound good on paper but just end up as intentional or unintentional fraud. Not everyone has a basic understanding of thermodynamics or engineering, or we won't have stupid ideas like solar roadways or the Hyperloop.
