both of them fake, i am sure. first

both of them fake, i am sure. first one, not enough energy to rotate longer arms which are on the lower pozition; second one, spring's energy is compressed and can't be turned to another kind of energy while still compressed, yeah it will push the bigger wheel but not in the rotational direction but to the central direction which can't produce any energy but only endurance; you are independent to try, but i am sure that i will not work, because its theory is not right....
