The paper is titled "Optically-induced charge separation and terahertz emission in unbiased dielectrics." The university is pursuing patent protection for the intellectual property.

This is totally over my head.

Just a quick calculation, (so probably wrong) you would need a reflector of about 100 metres square to concentrate ten million watts of sunlight into one square centimetre. That's assuming a pretty good efficiency for the reflector. So to be practical, you would have to extract a lot of electricity from a 1 square cm beam.

On the plus side though, the unused energy of the light could be used to make steam and drive a turbine. Or you could simply just use all of the light to make steam and drive a turbine.

It would have to be highly efficient, to warrant this approach. But maybe it is.

The combination of a fresnel lens with a Stirling engine is already employed in some big solar collections. Here is a small-scale demonstration:



If I had the time and resources, I'd make a setup for myself, but alas.

Anyway, the big version:

I could build one, but I have enough projects to build to last me 3 years at least (the Stirling engine that is).

I tried for a couple of months to make my own, but without proper tools, I couldn't get the piston within tolerances to the cylinder, nor could I get the doo-hickey thing, the rod that was to serve as the cam, to spin smoothly enough. I gave up and bought a couple of models from Japan.

The fresnel lenses I bought sure do work, tho. I set asphalt to burning within a few seconds.

However, as it turns out, the university frowns on that sort of behavior in their parking lot.

How's your recycled cooking oil fuel thing going?

How's your recycled cooking oil fuel thing going?

I'm still driving the same car, going on its 4th year of the experiment. Had to change the fuel filter once, but then I improved my filtering methods, so I doubt I'll have to do it again. I figured out how to avoid the runaway diesel thing by diluting the veggie oil with kerosene in cool weather, then going back to diesel in winter. No performance problems, either.

I was talking to a mechanic who had a 'runaway diesel thing' happen to him. If we are talking about the same thing, he said that you pretty much have to walk away and wait for it to fail.
I had a suggestion to choke the engine out. It would work in his shop, but perhaps be a bit impractical for field use.

The suggestion was that he take the torch of the welder, and dump argon into the intake until the engine quit due to lack of oxygen.

A cheap CO2 extinguisher will do the job nicely. I've done that on diesels in the Navy. There were studies that looked at building a smothering system into the shipboard systems. (We used diesels as emergency electric generators on the ships I was on.)

Well, if you're on the highway, as I was, you just put the thing into high gear, engage the clutch, and stand up on the brake pedal. The engine will die when the rpms get low enough. Same should apply in the shop, just be sure your foot doesn't slip off the brake.
