Portable, low maintenance energy

What if you had a power unit that generated substantial electrical energy with no fuel? What if it were so rugged that you could parachute it out of an airplane? What if it were so easy to set up that two people could have it running in just a few hours? ... SkyBuilt Power Inc. has begun building electricity-generating units fueled mostly by solar and wind energy. The units, which use a battery backup system when the sun is down and the wind is calm, are designed to run for years with little maintenance. Depending upon its configuration, SkyBuilt's Mobile Power Station (MPS) can generate up to 150 kilowatts of electricity, says David Muchow, the firm's president and CEO. That's enough to power an emergency operations center, an Army field kitchen, or a small medical facility. ... It works this way: Parts for each Skybuilt unit are packed into standard-size shipping containers. The containers, specially modified and strengthened, can be moved by ship, truck, train, or even dropped by a laser-guided parachute to the most remote location. Once on-site, the container is opened, and arms and poles are attached to the outside to hold solar cells and wind turbines.

So, this thing is the size of a tractor trailer. It is designed to put out 150 kilowatts max. That is enough to run a couple of houses. What is the one thing that has happened to ALL technology in the history of mankind? It has gotten smaller and cheaper on a daily basis. I picture a day when they build these things into the attic of the house. I mean, why would I be bothered about a couple of panels or a windmill on the roof if it is the norm in the neighborhood?
You know, nothing says we have to buy electricity at all. Nothing says we have to hook to the grid. I daydream of a house on a hill with panels on the roof and a well for water. We live our lives attached to a phone tower far away or a satellite. We  eat as much as we can off the land. The world knows we are here. We know he world. We are just happier in the woods, away from so many others.
I have been waiting for years for a better battery, or a better generator. The thing that will free us from so many wires and so many monthly bills.. This is one tool. fuel-cell phone batteries are another step. A tinny turbine engine for running electronics has been tested. There is a battery charging pad that you lay your devices on (no plug) to charge. I know the researchers that be, are feverishly looking for materials that will hold more energy for longer shelf times. The trouble with bottling up energy is that it wants to achieve a state of balance, in other words, explode.
I like self powered devices like the old windup flashlights and the like. I've recently looked at generators just for the hell of it. I remember someone designing a pair of shoes that charged a phone while you walked, but I cannot Google it. Now, they have drop-anywhere solar panels. Not too shabby. "shiiiiinyyyyy" as they say.
