I always had the feeling that with electricity consumption, smaller is better. What if we all add a few blocks in our corridor which would be lift up during the night and bring back energy during the day? This would get the curve plane and we can follow its usage closely, wanted to reduce our own bill...
- lovemenot 6y agoYour intuition is probably not right in this case. Gravity is actually very poor for energy storage. If your home system could lift 100kg over 10m it would store only around 3 Wh. The advantage of these industrial systems is that mass scales by volume, so a little more surface area can deliver a lot more potential energy. And of course the capital investment is much more economic on a centralised system.
- flaburgan 6y agoBut isn't that efficiency directly depending of the system itself? I mean the performance of the dynamo which would create the electricity when the weight goes down
- lovemenot 6y agoIt's not a question of efficiency. My figures assume 100%, which is certainly too optimistic. No, it's about the energy in any reasonably home-sized system is way too small. About one or two AAA batteries' worth. Though industrial-sized systems can be much better, they too are under-powered, against our needs. Except pumped-hydro.
