Re: High powered Stirling going into production

I think Inresol started another thread in 2015 and are still in business, anybody else have an input here? Yes, http://stirlingengineforum.com/viewtopic.php?t=1995 I haven't been in contact with Inresol for well over a year and finding no news here I googled for their annual report. The latest avai...

Re: High powered Stirling going into production

When I looked for info the projected cost of the Unit looked to be 5000 Euros on another over 7000 and here they are talking 30000, is this all a very elaborate hoax? Where did you see a price of 30 000 Euros?? If memory serves me right, 5-7000 could eg be for stand alone engines and some other sub...

Re: High powered Stirling going into production

They are avoiding technical details As is common practice before you have all the relevant patents in place for the new things you invented to use in combination with old technology. they did not explain the necessity to buy batterries Nor should they, as extra batteries are not a necessity at all....

Re: High powered Stirling going into production

The guys at Inresol are apparently rarely taking a peak here, so called them again today to ask how things are going. Most links on the webpage are dead because they are still hard at work producing manuals, spec sheets as well as several new videos of where/how to use the Genious. As the documentat...

Re: Antartica Extreme Cold Stirling,4C Hot water,-60C Cold A

Well, wasn't really thinking about heat exchangers as such in regards to a nitinol engine. More of taking advantage of the hotspots that appear (eg residual heat from cooking, or even excess body heat) and extracting some of it as electricity when that heats moves to the ambient room temp.

Re: High powered Stirling going into production

Noticed a lot of links on the website are dead. A mistake or are those pages & documents just not ready yet? Also, is the location Alvestad on the map correct? (Id presume it should be Älvkarleby?) Danny is also speaking about the product in 2 parts of a video and there is a referance to a third par...

Re: Antartica Extreme Cold Stirling,4C Hot water,-60C Cold A

Yes, no energy appears from nowere, so naturally a nitinol engine would partially suffer from the same issue as a stirling, excellently summarized by tomestre above "you will be using energy to heat your camp, and your stirling wil literally pump that heat outside." But since the thread is drifting ...

Re: Antartica Extreme Cold Stirling,4C Hot water,-60C Cold A

For a low temp difference engine, maybe a nitinol engine would be a better option?

Re: High powered Stirling going into production

It for sure could run a pelletmaker, but if you dont have use for all the heat created in the process, recouping the cost of the pelleter and your time spent doing it might be hard. As for "how many kg/h", I guess you can just count backwards. If using the stated 30/60/10 (elevtric/heat-controlled/h...

Re: house heating system with stirling engine

Well, I guess you are the expert, but this line feels Romanian (Latin) to me, not Hungarian (Finno-Ugric) "Cea mai ieftina centrala termica cu biomasa" as well as the melody of the language spoken in your friends video. :) In any case, what is your experience of feeding a J with long branches, does ...

Re: High powered Stirling going into production

The configuration described above also allows for a smaller house battery bank, which means a smaller environment footprint, because instead of having a large bank/high wattage inverter to accommodate large loads, the stirling is simply run during those times to power them directly. Indeed, and tha...

Re: house heating system with stirling engine

Looks good, unfortunately I have 0 knowledge of the Romainean language. Re the short feeding interval of a rocketstove, I was planning to use a lot of 1.8-2.0m braches, to allow it to feed itself. But of course, long straight wood is limited, so was thinking about if one could build a long tube that...

Re: Antartica Extreme Cold Stirling,4C Hot water,-60C Cold A

Re wind turbines, vertical models are generally easier to build, sturdier and can have all the heavy generator parts firmly placed on the ground. Also, gearboxes and other mechanical contraptions to turn it in different directions are not needed at all. Probably worth it to look into. :)

Re: house heating system with stirling engine

Hello Laszlo! I wonder, have you thought about making your own stove as well? Properly built rocket stoves reach very high temperatures (>1000 C) and literally burn everything when there is enough heat and oxygen present so there is no black sot left. That's likely very much more efficient than you ...

Re: High powered Stirling going into production

I completely agree with you Bumpkin. My own goal is to build a proper mass heating rocket stove, with a highly insulated heat riser acchiving complete combustion at 1000-1100 C and then feed the Stirling with that heat before it passes the "mass heat storage"-unit on the way to the exhaust outlet by...
