i don't see much of kevlar these days - he pops by once a week for a beer and to pick up building materials for his next project - but i do know he's been teaching elementary school again, including science class. he was telling me about his waterwheel experiment the other day but i think this would be way cooler.
create a lemon battery kevlar!

spinning a waterwheel to generate electricity is the coolest! And attitude from a eight year old won't get you fired.
