Searching for supplier that sells mircoturbines (*micro-braytoncycle

Searching for supplier that sells mircoturbines (*micro-braytoncycle

(OP)
I have a problem finding a supplier that sells microturbines (i.e. brayton or rankine cycle) or even a stirling engine that can withstand high temperatures (i.e. T > 300 deg C).  This engine is to be used in estimating the solar thermal flux impinging on a 3-d parabolic collector.  This engine should only be heated via solar energy: i.e. no hydrocarbon fuels or other substitutes used as a heat source.  Like I said before, this engine will be used to estimate the solar flux so it doesn't have to be the most precise instrument on the market.

If anyone has ideas, I would very much appreciate anything you can give me.

Thanks

What is wrong with conventional methods of measuring flux?  Why the turbine?

What do you mean by conventional means?  Photovoltaic?

I want to use a micro engine because I want to determine the efficiency of converting solar thermal into useful electrical energy.  Apparently, a solar stirling system can have efficiencies of ~40%, whereas a PV is ~10-18% efficient.

Once you calibrate the sensor, you're measuring the real quantity, the quantum efficiency is not relevant.

You can also use a calorimeter
