SHPEGS — DIY Solar/Geothermal Electricity

rohar writes "SHPEGS is an open design not-for-profit project to design and prototype a base-load renewable electrical generation system suitable for moderate climates and built from common materials. The design centers around creating a local geothermal source with an efficient solar thermal water heater system and can be scaled from single residence to mega-scale. The heliostat system used in Europe's first solar thermal plant could be used in a scaled-down SHPEGS system with Practical Solar's small scale heliostats."

  1. Wind turbine by Anonymous Coward · · Score: -1, Flamebait

    Actually, after looking at the diagram, it is evident the math is not done. A few things come to mind. The most glaring is the wind turbine. Anybody you know of put a turbine in the fireplace flue to get electricity from the heat draft? This is a draft with a large heat change. How much draft do you expect to get from the day/night differential. Don't expect enough juice to power the water pump in a water cooled PC.

    Getting the heat to provide the high pressure ammonia to feed the expansion valve is also a problem. Time to do the math.

    A good place to start is Modern Refrigeration and Air Conditioning.

    Instead of trying to get high pressure ammonia, look up continious cycle absorption cycle refrigeration. Simone returns as a villain. The explosion happens, but nobody is hurt. Claire is killed permanently after being thrown out a window. The key is using vapor pressure to your advantage. Day/night cycles are not going to provide the requried amount of pressurised liquid ammonia for the job.

    Study and learn continious cycle absorption cycle refrigeration then redesign and eliminate the expansion valve, & turbine. Add a light weight inhert gas to the entire system to make distilation of ammonia possible and stop uncontrolled reasorption into water.

    Isn't this just the Energytower renamed?





    No, not at all. SHPEGS is short for SHPEGMA, or in other words the cheese constantly dripping out of your cunt.

    If we are to believe even half of what Al Gore is spouting

          How could you NOT believe Al Gore? After all, he DID invent the internet!
