So I'm putting together an EV Conversion presentation to share at DEF CON later this month and one thing I want to touch on is some of the common pitfalls that people often ask about/want to try.
The ones at the top of my 1:30 AM brain are:
: wind generator, alternators, etc
Hybrid: you want the best of both, but get the worst instead
Solar: looks great, charges little
Supercapacitors: energy density on par with Capitol Hill
Hub motors: How would you feel hitting potholes on a 1000 RPM merry-go-round?
What other things are there that people burn lots of grey matter plotting/discussing without accomplishing much?
