I'm just now coming up to speed on the patent ownership issues surrounding the NiMH technology. This question is more of a general patent question, but it is it legal for an amateur to build something using a patented design for non-profit?
Completely ignoring the question of how difficult it would be to produce NiMH batteries at home (I'm assuming this is bloody difficult / expensive), how great would it be to equip all of these DIY EV's we're making with better battery technology?
If we could start an underground movement of homebuilt NiMH cars, we could change the world for real.
