Enoon Posted December 31, 2021 Share Posted December 31, 2021 (edited) I tried the website but got a warning not to proceed. I was interested to see if it used superconductive magnetic bearings. 1993: https://www.sciencedirect.com/science/article/abs/pii/0964180793904252 "These experiments point the way to large rotor levitation of 10–100 kg in the near term and 1000 kg rotors in the not too distant future" Edited December 31, 2021 by Enoon Link to comment Share on other sites More sharing options...

Led Lolly Yellow Lolly Posted December 31, 2021 Share Posted December 31, 2021 (edited) The problem with these things is they have to be buried deep underground in reinforced concrete chambers. Any failure of the flywheel will be catastrophic. Anyone with any common sense will NOT want 32 kWh of energy being released in one go, anywhere near their house. It would be like a car hitting your house at Mach 7 (I haven't done the maths but you get the picture).

Crossy Posted December 31, 2021 Author Share Posted December 31, 2021 Yeah, having seen what the relatively tiny rotor of a gyro stabilisation system does to the innards of the stabiliser itself when the bearings failed (it was doing 24,000 RPM at the time) I certainly wouldn't be wanting one above ground. The ones on the website don't appear to be in much in the way of containment other than being buried. Link to comment Share on other sites More sharing options...
Led Lolly Yellow Lolly Posted December 31, 2021 Share Posted December 31, 2021 (edited) Even when buried, the shock of a failure radiating through the ground can damage building foundations. It's essentially a bomb. I think it would be a struggle to make it practical, safe and cost effective in a domestic setting.

888huahin Posted December 31, 2021 Share Posted December 31, 2021 Seen this type of technology before, about 40yrs ago, it was used to as a sort of mechanical UPS to power the UK 50volt Telephone System, these Flywheels needed to buried under ground because of the huge amounts of kinetic energy and sat on floating magnetic bearings, next to no friction, no power loss, might even be spinning in a vacuum. It makes sense Battery storage is very expensive, inefficient and environmentally unfriendly. 1 Link to comment Share on other sites More sharing options...

Take a look at when the first PC (as big as a House) came and now we have one (with even more processing power) in our back pocket. Give it time give it time ????

tjo o tjim Posted January 5, 2022 Share Posted January 5, 2022 Having dealt with various flywheel systems over the years (Piller, Hitec, Active Power, and the one that was originally for hybrid busses), they have come a long way. 12MWs was doable and reliable 10 years ago, and maintenance was reasonable. That said, hard to beat LFP batteries today. 1 Link to comment Share on other sites More sharing options...
