this pyramid should produce electricity. (thomas trawoger's pyramid explaned.)

the first paragraph was a typo. i'm surprised you took it so literally.


the copper foil i use, is used outdoors. to line decks or roofs or something.
the surface oxidizes over. protecting the unoxidized layers under it.

you could look for copper foil online. then once you find something, see if a local hardware store has it.

Posting b4 leaving for work.

nitinnun - sorry man, was really tired last night and was taking pretty much everything literally no offense intended

I kind of figured about the copper foil - someone should carry it around here...I'll keep looking.

I just had a weird thought...would it make any kind of difference at all if the metals (copper & aluminum) were put on the inside of the pyramid structure? Or both inside and outside?

Since the thread seems to be losing momentum, I'm going to go ahead and try building what I can with foam-core. It may not be the best material, but it's cheap and I've got it on hand...that and i'm bored. I'll post pics soon.

Well, the main structure itself is done...I gotta say - that way easy. The first pic is of the 4 triangles taped together along one edge before standing it up. I beveled all the edges in when I cut the triangles out, so all I had to do was stand 'er up, slap one more piece of tape on 'er and she's nice and sturdy.

Interesting...my 9lb dog (the pyramid is bigger) just keeps looking at it, she jumped once...weird. I'll reinforce the edges with a little glue, then start looking for something to mount some antennae to. That may wait for the weekend however.

Feels kinda weird having a pyramid standing on my living room floor...

D'oh...forgot the second picture...it's really funny, my dog can't stop looking at it...


The dimensions that I used for each triangle: 60cm base, 48.5cm tall.
Deriving those numbers was just simple math...I took the ratio of height to base width and shrunk it down. It's close enough to 2 feet - metric actually worked better in this instance.
