has anyone tried to make a Brayton-cycle to drive say an electrical generator using(adapting) a piston, combustion engine turbo-charger?

does anyone have some new thought on Brayton Solar?

i am trying to come up with a setup that can produce a mechanical (shaft)output around 1KW. i have an automotive turbine (the turbine side of a regular turbocharger), and this should drive both: it's compressor and the abovementioned shaft output. i removed the compressor part, because it...

so you say i can still use my automotive t..c.?, and i only have to switch to say CO2 and add the recollector? what about the compression ratios? and the very high rpms? eduardo

the bottom line is " Solar Thermal", all your needs for a household (electricity,a.c. and hot water). but: no PV and no electrical storage batteries, the a.c. is absortion.

no it is supposed to be a closed air circuit

this is my actual setup. it has a garrett t/c meant for a large Toyota engine(amongst many), the heater (heat exchanger where i get via a graphite conductor the heat from a molten glass tank. the actual exchanger is an steel portion of an auger, meant as a drill for laying fence posts on farms...

thank you Peter, i have to take a good dive into your idea, let me try to figure it all together and i´ll be back rgds eduardo

i am very interested in the turbine configuration. bottom line, i am interested in generating electrical (around 1KWe) from thermal solar energy. all inputs are greatly appreciated. rgds eduardo

i have been involved in the same idea. i find that the only real hurdle is that an automotive turbocharger (or even a large industrial diesel engine turbocharger) are limited to very low pressure ratios (2.1 to the most), and the reason for it is simple, in gas engines you cannot overboost or...
