The Mechanical Battery
- angryearthling 19y agoflywheels aren't the only type of mechanical battery. http://en.wikipedia.org/wiki/Hydraulic_accumulator http://en.wikipedia.org/wiki/Hydraulic_accumulator i've often wondered how much power a simple 2-3 stone weight could generate for powering small appliances. kinda like the dynamo powered torches and radios but for permanent installations.
- Andys 19y agoThe datacentre where my servers are hosted uses giant flywheels to power the whole building for the 20 seconds until the diesel generators are ready to take the load, in the event of a power outage. I didn't know why until I read this article - they are more energy-dense than lead acid batteries!
