Re: [Biofuel] Home energy system ...solar and wind
years ago I penciled a 20x20 section of a parabola (cassegrain) and proposed storing thermal energy as latent heat in a m3 of FeCl. As I recall it was comprable to 5 US gallons of gasoline. I think the phase change was around 600F. Since the aperture to the thermal storage was the focal point and it re expanded before hitting the receiving media reradiation was reduced. Proposed insulation was foam glass which is used commercially by the refrigeration industry. The solar concentrator plans Teton has may be a good starting point. Redrok is another good resource. All the best Kirk BTW photos of the worlds least expensive windmill for pumping water should be soon. All I have left to do are the sails. Is basically a Persian windmill but I have dispensed with the wall and made it omnidirectional by making the sails self furling. A merrygoround and bedsheets.

working in that direction, but with a twist. The 10' parabolic collector can collect a lot of heat, and rather than convert it immediately to electricity, which I'd then have to store in some sort of battery (with all the problems that batteries come with, ie. disposal when they don't work anymore, and then having to acquire new ones..., ) it makes better sense to store the heat from the collector in 55 gallon drums of water, which can actually make up the rear greenhouse wall... I've been studying Stirling engines for some time now, guess I've read everything that Google can show me about them, crammed all the ideas into my head, noted the major disadvantages of most of them, (They've got to be airtight, precision power piston, most aren't self-starting, etc...) and have come up with a design that addresses these problems, and eliminates them by integrating much of the engine into 3 moving parts. Heat goes in,
electricity comes out. I really would like to build the prototype, but can't afford a machine shop to make a couple of its parts. Maybe someone on this list has the right tools to make the parts, and would like to see more detailed plans on this. Eventually, when a working prototype is producing electricity, the plans with step by step guidance will be under the "open information license" The point of the whole system is that wherever possible, the parts should be stuff that can be found at the junkyard, and that when completed, a home power generation system is running for under 3-400 bucks. Adding another collector just for home heat would be even simpler, under floor heat circulation would increase the cost due to plumbing, thermostat control, etc., but if the hot water was just circulated through a radiator (junkyard again) with a fan behind it, the home could be comfortable without huge expense.The efficiency
of a Stirling engine makes it a potential candidate for a hybrid vehicle, and I've been working on something along that line also, but first things first...Any ideas are welcome, anything I can do to help pull us out of the mess this planet is in, I will do.doug swansonJason& Katie wrote:>you dont need money if you can supply a need. i know more than just fuel, i >can build just about anything a person would have as a daily need. house, >furniture, small macines, engine repair, anyone with a skill is pretty well >safe. it is the people who have never had to work a day in their life (CEO's >and politicians) that are screwed.>Jason>ICQ#: 154998177>MSN: [EMAIL PROTECTED]>- Original Message - >From: "Mike Weaver" <[EMAIL PROTECTED]>>To: >Sent: Friday, July 14, 2006 9:01 PM>Subject: Re:
