<t><br/> I try to bite my lip lately, and be quiet, but think about what you are being told. Your solar thermal will create 'too much' heat? To them, it is a problem if temperatures go above what would turn the fluid in the system, water, to steam.<br/> <br/> Some industrial evacuated tubes are rela...

<t> This quote was cut from a New York Times article today:<br/> <br/> "According to a 2007 geothermal report financed by the Energy <br/> Department, advanced geothermal power could in theory produce as much <br/> as 60,000 times the nationÂ’s annual energy usage. President Obama, in <br/> a news c...

<t>Well, just last night I was reading about a new NASA design alpha Stirling that produces 50 kilowatts, and will run continous for decades. They are very interested in dynamic engines, instead of the old thermocouple types, because the dynamic ones get three times as much output. There are no cuur...

<r><br/> The government is actually the best source of open and free information for new energy devices. Most of the hard math and lab work has been done to sort out most basic theories. You already paid for it, and it is sitting there. Look at the archives of major government labs.<br/> <br/> The r...

Sorry, I messed up. I confused F and C degrees. Delrin will melt at 150 deg C.

You ever heard of a material called Delrin, also known as Polypenco in the U.K. ?

It should be OK at 150 degree C, is machined like the soft metals, like the aluminum, will not expand or contract, and should be strong enough.

one idea for you, anyways.

<r><br/> I went to the web site.<br/> Very cool to see a nice web for the ST-5.<br/> It must be getting close.<br/> Very cool pics page.<br/> I wish there was more of the insides of the engine.<br/> Lots of old ones and models, too.<br/> <br/> I was watching the pics of the belt systems running and ...

<t>Hello Antoine,<br/> <br/> I had to actually look up Sahel.<br/> <br/> "It is a transitional ecoregion of semi-arid grasslands, savannas, steppes, and thorn shrublands lying between the wooded Sudanian savanna to the south and the Sahara to the north.[1] The countries of the Sahel today include Se...

<r><br/> wow...<br/> <br/> Robert is ramblig a bit!?<br/> Well, I have rambled before, but I think he does not understand the unique properties of a Stirling, he does not understand we are here to promote that particular engine design, and he has some fear of exploding oils that is beyond reason.<br...
