Permanent Fortification, or Camp, or Shelter

Or to be more accurate, a structure that can instantly be assembled, and instantly disassembled, and is a shelter that lasts indefinitely, and in which all modern conveniences can be included, and can be built in any climate.

What is needed is a geodesic dome, some kind of thin plastic material to be shingled with the use of "grip clips", and then dirt is put on top of that, for heat retention, and to keep the plastic from creating a greenhouse inside.

Geodesic dome: The most primitive version is to use sticks, of exactly the same length that have the ends carved flat with a knife, and then a hole is drilled into the flat end. Then they are assembled with standard nuts and bolts at the intersections.
The second better way of construction is just substituting metal electrical conduit for the sticks. The ends are flattened with a hammer and then a hole is drilled into the flattened part. Then connect them with standard nuts and bolts. This should only cost around 50$, if you already have tools. See: This video.

Thin plastic material: The most primitive version is standard garbage bags. The thicker the bag, the better, so that it will support heavy dirt. These are shingled onto the geodesic dome with "Grip clips".
The other material that may be used is ordinary camping tarps, of any color or type.

Mound of dirt: First you need a piece of land. Then you pile dirt over the geodesic dome, if you live in an environment that has dirt. If you were to put a layer of foliage over top of the dirt, or plant living plants(Such as moss or grass) into the mound of dirt then you wouldn’t have the problem of erosion of the mound. If that does become a problem.

Theoretically this camp can be constructed in less than a day. And has a wide range of environments that it can be adapted to. Such as in temperate climates you wouldn’t need a mound of dirt, but instead the plastic layer would act as a greenhouse. Or in extremely cold climates you would have the dirt on top of one geodesic dome, and then you would have a second geodesic dome and plastic over top of everything, to act as a greenhouse that would also store heat during the night.
And if you don’t like cold or hot climates then migrate south for the winter every year, to your second property.

Modern Conveniences: First you need a solar panel and a battery and an inverter. Watts= Amps(x) Volts. With the money saved on rent or a mortgage you can buy at least 500$/mo of new modern conveniences every month.
Warmth: An electric space heater.
Air conditioning: Wear a wet shirt, when it's windy it's like being in a fridge. Or have a thermo electric "solid state" air conditioner(Solar panels are the key to marketing this device, because solid state is less efficient that standard mechanical AC).
Furniture: Foldable or inflatable furniture.
Food: Either live off the land, or go to the store.
Refrigeration: A "solid state" portable cooler, that is solar powered. And it makes its own ice that lasts through the night. Or just have backup stored solar power. Or an ice box with a tank of water next to it that is frozen with the thermo electric effect during the day and melts during the night(Yet to be invented, because no market for it yet). Which would mean no need for a battery to store daytime energy that would be used to run the fridge at night.
Clothes washing: Either have synthetic water proof clothing(100%nylon/acrylic) that you wash with alcohol and lemon soaked rags. Or a bucket of soapy water and a clean plunger to agitate cotton clothes with.
Shower: Soapy water, and a rag, and shampoo.
Entertainment: Depends on you tastes. Have satellite internet on a laptop (AT&T laptop connect card), and watch shows on their network site. Have DVD’s on laptop. Have video game ROMS and emulators all on 1 flash memory card, and a USB controller(10$new, or thrift store).
Lighting: Florescent, or lots of super bright LED's, or flat/flexible OLED ceiling light(Yet to be invented until around 2010).
Flooring: Plaster, or adobe bricks that are put down and then soaked with water to bind them and to strengthen them. Or your own personal preference of flooring over top of that.
Cooking: A rocket stove made out of adobe. Smoke meat, on racks over a smoky fire.
Fresh water: Boil rain water, or put into a simple distiller, or chlorinate and let the chlorine evaporate from the container, before drinking.
Transportation: Have GPS to find your land locked property or deserted island. Then get there or anywhere with an AC induction motor, and super capacitor powered vehicle(Yet to be invented until late 2009).
Communication: Cell phone.
Bathroom: Either a bucket with a bag in it that you burn later, or the less smelly and easier version of having a bucket with water and a chlorine tablet in it and also CLR septic system acid. and you bury it in a hole nearby when disinfected. Then reuse bucket. This is either in a wooden structure or open air with tarps for privacy and rain. But if there is hardly any smell, because of complete disinfection, then just have it in the house, and chlorine off-gassing won't be a problem with only one pool tablet, or a lid put on the bucket.
