Obviously this system could be scaled to suit for household requirements..
The system can even be partially hidden to lift and drop heavy weights into 6" wide deep underground wells.
To my way of thinking,this tech is a no brainer,especially in a country of brownouts short and long like the Phils!
Use the sun to lift the weights via surplus power during day time and then rely on gravity to provide required power during night time hours.. Might not be cheap to set up but could provide constant power for at least the lifetime of the panels.. 25 yrs.
