hi Timshel,

keep in mind that "energy" does not always mean electricity. If you're trying to deliver a green message, you could compare the amount of energy required to make a can/bottle/paper from scratch vs recycled. I've also done demos that compare how much energy/exercise you need to do to burn off an MnM vs a carrot stick. If they really want you to do electricity, you could get a hand generator and compare the amount of work required to light CFLs/LEDs/Incandescent bulbs. 

good luck! I'm sure the list will give you more ideas than you possibly could use.

HI all
I have been asked to come up with a "wow" energy demonstration for a festival my museum is hosting in March. This is a bit out of my realm of experience so I am asking for ideas and help.  (My museum is a natural history museum and most of the demos and activities we do are biology/evolution/water related).

The example I was given was "you know-like a bike to power something."   My concern with that is it's very popular and everyone else has done it so I'm not sure how "wow" that is.   Anyone ever tried some sort of electronic pad where people jump up and down to generate electricity?    I was also wondering about "energy vampires".  Our local power company (who would help fund this) has a large campaign on reducing energy vampires in the home.  Does anyone know a good resource for how much energy different appliances that are plugged in use-and how much human powered energy would be equivalent?

Any other ideas?  I did look through the archives of this community and got a few.
THANKS
