I just paid $24,31 for an iPad2-64GB and my girlfriend loves her Panasonic GF 1 Camera that we got for $34,26 there arriving tomorrow by UPS. I will never pay such expensive retail prices in stores again. Especially when I also sold a 42 inch LED TV to my boss for $678 which only cost me $68,18 to buy. Here is the website we use to get it all from, CentSpace . com
Dome homes still have great potential. Modern systems like flexible water lines and radiant heating would make them even easier to construct. They could be made from recycled materials like plastics and engineered wood products that produce less waste. Domes could be sprayed on the outside with shotcrete for durability.
At this time of economic instability, their greatest asset would be that they can be mass produced cheaply and still be strong and durable. So many people can no longer afford to even rent a place to live that something needs to be done to provide shelter for them. A geodesic dome could be the answer because it can be assembled quickly and disassembled easily when no longer needed. It is also cheap to heat and easy to scale up and down. They are stronger than mobile homes and don't need a frame and wheels built under them for transport.
Perhaps our government should consider building these for the homeless instead of wasting billions on war planes we don't need. Imagine how many could be built for the cost of one advanced tactical fighter.
seems like fun. i wonder if i can still get my hands on the plan?
