"set up a system of gears and weights, and using gravity, spin a turbine as the weight falls down. watso does not know the maths of it all , but surely if a person raises enough bricks to a high point, and then harnesses the energy as the bricks fall (gravity), then surely there should be enough energy to power several led lights."
That's why I said he could carry the bricks in a subsequent post.
Was referring to this part @Hanrahan not the pedal generator part.
I trust him that the pedal generation part is correct and true.
