The other evening 42 pushbikers dropped over while I was making dinner! There was a crisis! What to do with them all?
In actual fact, this was the number of pusbikers I'd have needed on stationary bikes to pump the electrons through the house to run the oven, lights, and other household things. A brand new SEG gadget.
It's interesting to learn more about energy in context, particuarly when it's something that we can physically exert.
Electrons are hard to pump.
