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.

Sheesh!!!  Women.

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.
Interesting though!!
