    Stirling Engine

    I've been getting more and more interested in this... I'd like to build a 3KW home generation unit...

    It appears a 9ft reflector with a scaled down stirling heat-powered engine could turn the gen.

    I havent' found much for the home user, as utilities want to keep the money flowing in THEIR direction, and a home solar unit would certainly dent their pockets in a region like Phoenix, or many of the southern belt.

    If you do something like that, the electric company will have to put in another type of meter that will allow any excess power you produce to flow back out to the grid.

    Basically, it is possible that the electric company could owe you money at the end of the month.

    In addition to the dish and engine, I would think you would need a solar tracking system and alignment motors.
    Any idea how much the total installation might cost you?

    How often would the mirrors need to be cleaned, to keep the efficiency good?

    Looks like you just wash them down with soap and water. If the dish is only 8Ft, shouldn't be a big deal. I have no idea how much this cost... sort of like building a conversion ski. Just jump in and see if it works.

    Interesting reading for sure! I noticed some quotes on the bottom of the webpage..

    "If you are one step ahead of everyone you are a genious" If your are two steps ahead of everyone you're a crackpot" I guess this makes Hydrotoys a crackpot with the GPRXP conversion!

    I would love to add to this post but there is this little thing called an NDA that keeps me quiet. I can say this if you generate more electricity then you can use in your home your meter will turn in reverse. I have worked with several Solar and CoGen projects in the early 80's they kind of fizzled out. Now there a new ressurgence in this field. Been doing some work for these guys lately http://www.soliantenergy.com/index.php

    Well,
    I'm going to make a home-sized gen unit for myself... it's just a matter of time. It looks like there is about 3-5 different technologies to harness.
