Initially 300 tonnes, raised through 500 metres, not accounting for transmission losses I got 409 kWh, which is quite a lot, so the load could be reduced some what. I'm more interested in the motor-generator though, whether ones exist that could be applied to this problem and if so how much they...

I've been searching for a suitable motor-generator (Dynamotor), but the largest I have found is a mere 2 HP! Does anyone know of any manufacturers that produce larger ones? The system would be used in a small remote community (with suitable topography) to store energy generated by an...
