My other half is also an engineer and she admires Carol Vorderman. I asked
her if it was because Carol was a good engineer? No. Is it because she
trained in an almost all male environment and still made it through? No.
OK, I give in. Why is it you admire Carol Vorderman? She married a good
looking guy and got a job on the TV.

Umm do you have any idea on the weight required.
I reckon my average consumption is around 2kW.
Lets assume need to store energy for 24 hours supply.
Lets assume maximum height available, practically, is 10m.
PE = mgh
2kW for 24hrs is 48kWhr
48kWhr = 173MJ
Solve for m in equation ----- err 1600 metric tonnes, and that assumes 100%
efficiency in recovering the energy.
Yep, sounds practical to me!

I think the Germans experimented with energy storage systems in buses back
in the early 1930s, they used a heavy flywheel system which absorbed energy
when breaking and releasing it for accelerating, ideal for a stop and start
vehicle but god knows how they arranged the pulley/ gear train to achieve
the necessary power transfers.
