I would think storage in insulated water tanks would be much cheaper. That principle is used by some hydro electric plants that pump water UP to the reservoirs when there is excess electricity available.

The energy from cheap solar thermal heaters could be harnessed to heat gases or liquids to actuate the hydraulic lift mechanism as well solar electrical power or even manual power as an emergency back up system, just like our former generations of lighthouse keepers used pulley systems to lift weights each day to rotate huge mechanical systems of lenses and mirrors each night as navigation beacons.

Thus, the complete needed technology for storing residential solar energy in a special heavy-weighted energy storage elevator is already available. The "overall energy" use for tall building elevators is very small ( just the cost of resistance and inefficiency ).

Elevators usually use counterweights (in best case another elevator going the other way) to decrease the force needed. Lifting weights is one way store energy. I would be interested in hearing a real life example that is economically competitive with Insulated water tank (for heat) or batteries for Electricity.

Maybe ideas :-) The old fellow in the video doesn't really sell them either. He tries to get local entrepreneurs to make simple panels from large commercial PV sheets. I don’t SELL anyTHING.

Im using a solar panel in a demonstration in my thesis in the university of Limerick how to produce hydrogen the only problem is it wont work under ordinary bulb and it is essential that it works and seen as I live in Ireland there is a good chance that there wont be much sunlight. Any chance you know where I could get a bulb that it will work under? Thanks a million. Nice vid!!

Most PV panels produce for ordinary visible light so I would think it's "just" a question of getting enough intensity. Unless the panels themselves are the special feature (very high voltage?) it would seem to me that you just have to have a battery backup in case of no sun.
