I am working on a prototype model for a Density Dependant Counter Gravitation Device.

 

In order to do so, i need to construct a light weight vacuum chamber in the shape of a 3 meter cube.

 

that said, i have NO CLUE how to do so. So i have turned to the brilliance of the engineering team at these forums.

I need to know any:

Materials

Preconstructed, Standardized Units that could be intergrated AS materials

Costs included

Construction tips, or links to web sites with such tips

And any other help that you guys might be able to offer.

 

And please don't hate on me so to speak. If you find this thread absurd, or if you think it can't be done, please move on, dont post flames or call names or any other evil crap like that.

 

Thankz for your help.

Does it need to be total vacuum (insofar as that's possible in engineering)?

 

Why a cube?

 

I ask because a cube is not a very strong shape when you evacuate it.

Why does it have to be 3 meters cubed? Thats really big, maybe you should try building a smaller prototype first?
