Re: Increasing Thermal Conductivity
Bright Source Energy does produce Megawatts. Their turbines are over 100 megawatts in capacity. These are gigantic plants. However, my belief is that they don't achieve anything with such a large scale. Their material usage per kilowatt is still greater than reflux receivers/stirling engines. I'm cu...

Re: Increasing Thermal Conductivity
Thanks for the reply. One of my goals is to compare material usage per kilowatt in a sodium reflux receiver/stirling engine system based on Na/He heat transfer to the material usage in a steam boiler/steam turbine system based on H2O. For the same efficiency, large steam turbines are about three to ...

Increasing Thermal Conductivity
In stirling engines with high power to mass ratios, all the heater heads I've seen use many round(or oval) tubes to transmit the thermal energy from the heat source to the working gas. As the helium(or other gas) passes through these tubes, it acquires thermal energy. The purpose of these tubes is t...

Re: Hi
Good luck with the engine you are building.
