Don't be boxed in. Resort to ecological principles: Money does not exist. Only energy, perseverence and imagination are needed but these resources are limitless — unaffected by the laws of supply and demand.
Go ahead and do it. Pay homage to the sun — the original source of all your energy. No one can tell you the way to build a dome or a zome or whatever. Create. You are your own architect. Work with what you have — energy — and scrounge the rest.
Play with models. Experiment. Use stiff cardboard cut into geometric shapes and taped. Get your energy going and the dome's synergy will carry you. Scavenge and scrounge.
As America rots in its garbage, you can survive on the waste. Materials can be had from schools, construction projects, demolition sites, people, industry, lumber yards. Much is laying around dumped. America, in its greed, will give us our sustenance. From dead cars in junk yards you can get valuable metal tops, sometimes just for the effort.
More information can be found in libraries and government documents. Ideas are free and the energy is there. Liberate your ecosystem. Ecology begins with yourself.
We are at a college. A commune — Libre — visited here and turned us on. Now we have a 22-foot dome added to our environment. We got free tools, space, use of a station wagon, railroad ties, 2-by-4's, nails, fiber board, siding, paint, plastic skylight, money, and advice from a professor who built his own house.
We had no plans on how to build a dome in 107 easy steps — there are none. We did not know what we were doing when we started, but we learned a lot.
It will all be useful again for our survival in the coming environmental crisis.
