Tim -
Something that has had a big 'wow' factor for us has been to hook up a hand crank to a set of 10-15 incandescent Christmas lights, and then to the same number of LED lights. (Kinda what Marc was saying) They have to work pretty hard to got the old style lights to stay lit, but the new efficient LEDs light up easily. Everyone goes 'wow' when they do the LEDs, and it is a good demonstration for becoming more energy efficient at home. And yes, I am sure it can be scaled for a bicycle ;)

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
