how does that work not researched it at all what is the ice water for?

A google search of "elevator return energy", found that modern elevator systems in tall buildings do have special drive mechanisms that generates return energy when the elevator is going down. Thus, the complete needed technology for storing residential solar energy in a special heavy-concrete-weighted solar energy storage elevator is already available. The "overall energy" use for tall building elevators is very small ( just the cost of resistance and inefficiency ). No explosive hydrogen.

I was wondering how much time did it take you to do this proyect. how much precicion does it take to do one. and how hard is it to get he materials.

can someone plz help me, im looking for a science project and i think i found one. i have a few questions, how much does one cost, where can i get one, if i cant buy one where can i get plans, and how long would it take to build one

Great Video!!

ive seen a lot of these, but none actually yet that have harnessed the power, for example you could build a simple rechargeable battery charger onto it

you're right, for instance the hot gas could be used on a dynamo type fan thing on the exhaust, and maybe some kind of external source engine (like the stirling) for the engine heat byproduce

yes however they are extremely efficient
