Sure you wanna stick with "But you can also make it move with a washing machine motor if you use enough gears...."
The problem with that analysis is THE GEARING ISNT 100% EFFICIENT, I.E. THE GEARING FRICTION CREATES HEAT LOSSES AND THATS ENERGY LOST
The thing is if you had engough gear boxes and gearing down it takes HP to turn all those heavy gears, theres friction and heat, and I doubt a small HP motor would even turn that big of a gear box LET ALONE IF YOU PUT A LOAD OUT ON THE END.
A gear down box REDUCES RPM but INCREASES TORQUE,,,,If the gear box had no friction and produced no heat losses, since HP is a function of Torque x RPM, the HP out would = HP in buttttttttttttttttt it takes up and wastes HP in conversion to heat so you DO NOT END UP WITH AS MUCH OUTPUT HP AS INPUT HP
HOWEVER (cant create energy only change its form) HP IN ISSSSSSS EQUAL TO HP OUT PLUSSSSSSSSS HEAT LOSS....the gear box cant create or destroy energy, only change its from from HP in to HP out plus heat
