Interesting, I never tried mixing heated ingredients to make solid rocket fuel for model engines. We used a specially shaped ram with wet fuel, kind of like dough. You put in clay first to ram (press) the nozzle at the bottom of the tube, then the fuel. When it hardened, there would be a cone-shaped hollow up through the solid fuel. Worked good but you couldn't get too long with the tube or it would explode in flight. Read about the dangers and follow safety rules and you will likely remain alive.

Hi all, I used to be fascinated by this stuff when I was a kid and used to do a lot of pyro with building solid fuel model rockets. My friends and I would mix the materials on the kitchen stove and pour the molten fuel into cardboard tubes to harden around an cone shape at the bottom of the tube. Once electronically launched on our pad they would shoot up maybe a few hundred feet. That ended abruptly when I smoke bombed my mothers kitchen once accidently when mixing the ingredients!! So, I had done a lot of reading on rockets, ram jets, scram jets, v1, v2,s etc. Really fun stuff. If memory serves me correctly, Hitler used liquid paraffin and kerosene in the v2's. They were only designed to run for several minutes in flight. His scientists had also tried liquid parrafin and alcohol. One of the problems with these types of systems is that they used an incredable amount of fuel to operate for any length of time. Many air tools operate on an air turbine or piston design. You only need around 90psi to start doing some worth while work and it wouldn't be too hard to generate with wind or solar. I have operated a model air motor on compressed air for about 20 minutes with one of those tanks for tire fill ups @40 psi. Sizing up such a system might be very interesting. I have often though about a home system of wind /solar generated compressed air for use to run a turbine when there is no sun or wind. I have to do a lot more work on the cost effectiveness of such a design and component sourcing for a prototype but it is definately not that far fetched, unless I, or someone else convinces me otherwise. regards tallex Alternate Energy Resource Network 1000+ news sources-resources updated daily http://www.alternate-energy.net ---Original Message--- From: Manzo, Emil [EMAIL PROTECTED] Subject: Re: [Biofuel] Cross Posted: Fwd: [DIYGasTurbines] Re: I'd like to try something...but first, your opinions (please).

Re: [Biofuel] Flywheel 'batteries'
I love the idea of stationary flywheels too. Vertical is best IMHO because it's easier to share the load between two (plane) bearings instead of one and they are super-simple compared to the vacuum bottle type. Just make sure your rim speed never exceeds 60 MPH. See this interesting old-time site: http://www.rustyiron.com/engines/flywheel/ . Ferdinand Porsche used a flywheel system (spun by hand) when he was a teenager to power lights in his home. He was also a pioneer in producing a mixed system for powering vehicles. Today we call them hybrids. How long would you expect this energy to be stored? How would you make use of it?

Flywheels are another painfully efficient old technology, still in use today in your typical piston engine for load leveling. It's just that the load leveling happens over fractions of a second rather than over hours or days. Chrysler tried a flywheel car - it almost worked. I expect it was another intentional failure. Anyway - flywheels to store angular momentum are the way to go, just like using solar for heat is a more efficient path than PV. Flywheels had a problem in cars because cars may tilt (uphill, downhill c) which causes grief if the bearing system can't comply with the change. A stationary flywheel (likely horizontal) would be a fine way to store horsepower-hours, if you can overcome the friction issues. Magnetic bearings and a vacuum bottle would be required.

Re: [Biofuel] Katrina slams New Orleans. Is There Blame?
How right you are. Living in Florida USA my mortgage requires storm insurance. Our carrier cancelled us (no reason given). Upon renewal we expect a higher premium but there will also be extra charges to fund the uninsurable. I thought it was noble to help protect the poor but later found that Uninsurable means beachfront. So, I will be subsidizing those wealthy folks living on the beach. Fortunately over the years we accelerated payment on the mortgage. We have a plan to pay it off and drop the insurance all together. There is a moderate risk here, as there is almost anywhere else I guess. But you folks nailed the issue right on the nose. Insurance is meant for intelligent risk, not reckless stupidity. I don't know where this mindeset originiates.

Re: [Biofuel] Cross Posted: Fwd: [DIYGasTurbines] Re: I'd like to try something...but first, your opinions (please).
Hi Joe. When you said Pulse-jet you reminded me of something I saw when I was a kid. It was a small jet turbine that bolted onto your cars differential. It bolted in place of the rear differential cover and connected to your fuel and electrical system. As the car ran down the highway, the turbine came up to speed and you could flip a switch and inject fuel into it for a boost. Primitive but effective. I bet one of these would run well on biodiesel. Your pulse-jets are fabulous. At first I thought they were scram-jets but then saw the turbine. Cool.

[Biofuel] Solar panels
About 8-9 months ago I read a report about a man who invented a process that yielded a high-efficiency solar panel. Like 90%. The process reminded me of the way they make super high density integrated circuits. His website was ardev.com and when I went back again it went down (I think its some kind of flower site now). The announcement said he refused to just sell off the patent because he wanted it to actually be produced. He was teaming up with Westinghouse to produce the solar panels. Anybody hear something more about this? Perhaps it was BS.

Re: [Biofuel] Solar panels
Hi Joe, thanks for the link. On page 2 it states: Indium gallium nitride solar cells could be made. approaching the maximum theoretical efficiencies of better than 70 percent. The article I read centered on the patent of a deposition process. I dont remember the elements used though. Definitely a good read! With RD going on worldwide, theres bound to be more energy breakthroughs in our lifetime.

Check this link http://www.lbl.gov/Science-Articles/Archive/MSD-perfect-solar-cell.html In a nutshell it works by varying the doping level of indium in Gallium Nitride so as to smoothly taper the bandgap of the material from low to high energy. This is a step beyond the multijunction cells which are the highest efficiency (25-35%) and extremely expensive used in the satellite industry. This approach could potentially use a graded profile of indium doping in a stack of junctions so that photons from the entire energy spectrum will find their home at some point within the device. I don't think this approaches 90% (is that an exaggeration) but 75% may be doable. This technique would require an MBE (molecular beam epitaxy) which is a ridiculously expensive ultra high vacuum deposition tool and material growth rates are painfully slow so although it has the potential to make super PV cells don't hold your breath to see them on the market. General consensus is that the viability point for the comercialization of solar power is somewhere at the dollar per watt mark. However these predictions were made based on some standard economic benchmarks. Due to what peak oil could do all bets are off on this figure for the future.

Re: [Biofuel] Alternative to Toxic Mold Compounds?
Hi Mike. I was restoring an old car once and made a part I couldnt afford to purchase. Try looking up a company called Castolite (The Castolite Company 4915 Dean St. Woodstock, IL 60098 (815) 338-4670 (815) 338-4671) they have all kinds of mold making materials.

I know that this may fall outside the scope of our usual discussions but, I thought there might be knowledge to gain here. In the process of building a prototype solar tracker, I'm stuck with a dilemma. Some of the parts I make need to be molded. So, I'm making silicone based molds and casting the parts with two-part polyurethane. According to the MSDS sheets, the catalyst for the silicone mold is a tin-based compound and very toxic. The reason I started in this directionis that it's readily available, widely used and proven to work. When finished, I can cast parts in almost any material. I can even pour low melt temperature metals. I would liketo make/use a casting material from something which is safer to me and the environment and still be durable and weather-proof. I was making pasta the other night and found (the next morning) a couple of pieces of spaghetti, dried and conforming to the shape of the colander. It made me wonder if there is a casting materiel made of carbohydrates and /or starch that I can use with a latex rubber mold. Any thoughts?

Re: [Biofuel] Removing water from WVO
Thanks Kieth. You know how newbies get so enthusiastic digesting information at lightning speed and missing a lot?

It is becoming clear to me that accurate testing and processing of your WVO will save time, money and yields a better product.
