SOUNDS good but I foresee a lot of problems. Not that there aren't a lot of problems with the current space program already!
Okay, we would need to transports all the materials to the building spot, no? I assume those materials would come from Earth, no? The magnitude of it all would require many trips from Earth to space with these materials.
Can we use an overunity device to supply the energy we would need to power everything? The COP of this device would need to be pretty high. We're talking about tapping into zero point here. This would give us the CONSTANT supply of energy we need, possibly coupled with solar cells.
Also, how many plants would be needed to supply enough oxygen for 500 people? Are we using hydroponics or soil? Either way, we need a supply of nutrients for the plants. They can't survive on just water; we'd need a CONSTANT supply of plant food.
Are we eating plants too? Oh, my! Now we need twice as many or more plants. What about us carnivores? Perhaps we are all adopting a raw vegan diet?
As for waste by-products, I think maybe we could siphon them off into a separate containing station for a while. Of course, we could recycle SOME by-products. Bath water and other sources of water that aren't too gross might be re-used on plants before it is recycled for use again. We could build a water distiller. I know how to do that. Perhaps the whole geo-dome could be fitted with a system that allows water to evaporate and come back down again, directed to strageticaly placed containers. (This would be our version of rain.)
With a COP on the zero point power source (from the vacuum) we could sustain the operation of the city. The thing I can't figure out is how do we sustain the plants without having to mine Earth? Is mining Earth in your plan?
Anybody else have any ideas?
