This is the same turbine we used for the garden water hose test. 680 volts with a small air hose with only 16 of the total 18 coils connected. It can be powered with water, air, and/or steam. It is driving our smallest supergenerator. The same turbine and generator can be used in limitless ways to create power. These turbines will be made from everything from aluminum to high temperature alloys. lab@ftcenergy.com /386.575.0088/(Sales) 714.924.2058
Home made 10′ x 3′ solar water bag system for heating pools. It’s a stackable low cost inflatable solar panel system for heating pools without the need for a perminant structure, permits or home owner association approvals. It steals some of the water from a pool jet, heats in the sun and puts back into the pool. You can make one bag in an evening out of a commonly available heavy black plastic sheet and some common PVC parts that connect to garden hoses and low cost garden hose valves.
a short video showing the small solar water heater i designed a couple of days ago. it consists of 136 feet of 1/2″ black tubing. internal diameter is actually 3/5″ (cost approx .00), 4 connector pieces (to connect the various pieces together and to connect it to the house (cost approx. .00)), and finally the ‘y connector’ so i could have the garden hose hooked up at the same time (cost approx .00). all purchased from home depot. total cost was approx. .00. all i did was coil 100 feet of the hose and attach it to a piece of plywood. after 30 minutes of sun the water temperature is about 130-133 degrees and after 60 to 90 minutes it can reach 150 degrees. the tubing can hold about 2 gallons of water at a time. if you drain and refill several times throughout the day you could easity get 10-15 gallons of hot water a day. of note: they call the tubing 1/2″ but the actual internal diameter of the tubing is 3/5″ (.6 inches). 100 feet of tubing holds 1.47 gallons and 136 feet of tubing holds approx. 2 gallons. home depot sells a 500 foot roll for about .00. that would hold 7.36 gallons of water.

Unfortunately this was one of the only relatively sunny parts of the day! =/ this will have to sit for another day or so, but my findings so far were not bad. Went from Around 32F Cold tap water to between 90-100F in less than 1 minute of time for water to get from beginning to end. Or Around 0c to between 30-40C with just 7 Turns of Pipe. In Droplets. Test 1. Outside Temperature Minimum at 15C and a high of 18C with quite a few cloud brakes.. About 10 minutes of relatively constant heat occured. The other 5 minutes, medium to full cloud cover. The oil really did not have enough time to get that hot, as I felt the foil which sits right on top of the oil in some spots. It was scalding hot, but not even close to the temperature the bottom reached.. Simply not enough time.. I am thinking 15-20 minutes of constant sunlight for everything to be heated up to above 40C and still more time for higher temps. If I can get that pipe to above 100C at least in the center of the pyex, the water will increase in temperature much faster and may not require many more turns of copper coil, if any. Still some findings yet to be discovered. More Current will mean Cooler Water, so more copper rounds of coils or heated areas will be required. Thinner pipe can be used also but this mean less current possible. Thinner pipe will improve the performance and efficiency. I just figured this is a reasonable thickness and too thin will prohibit larger amounts of water to be passed through at a time …
