How are you proposing we produce 10W to heat clothes? we produce around 80W just by sitting idle, just wear insulating clothes! How do you produce 10W to power an electric bike? 10W is a laughable amount of power, just get rid of the electrics and pedal a bit. 10W is barely enough to charge a phone these days. Anything that gets moderately hot while in use is consuming more than 10W.
