There are systems that use concentrated solar to heat compressed air that drives a gas turbine. The efficiency of a gas turbine is limited by the temperature difference between the heated gasses and the exhaust gasses. The solar turbine heats a surface that heats compressed air. The temperature is limited to the melting point of the heated surface. If it was possible to heat the compressed air by passing it through the focal point of the concentrated sunlight, there would be no limit to the temperature.. But sunlight seems to go right through the focal point of a magnifying glass with little or no effect on the air. If ordinary sunlight causes some ionization of the air, then there should be more ionization at the focal point of concentrated sunlight.. If the focal point was located at the center of a powerful magnetic field, and high voltage plates were arranged near the focal point, some of the ions and electrons would be trapped if only briefly. This would cause more ionization at the focal point which would cause more ionization , etc....... at an accelerating rate. If the concentration of ions and electrons reached a certain point called a critically dense plasma, , sunlight would no longer be able to pass through the focal point. The plasma might heat up to millions of degrees. Ions and electrons in the compressed air could be separated by an insulated high voltage positive charge at the center of the turbine. A cylindrical plate around this electrode would be hit by electrons trying to get to the center and drive the ionized air away from the center. If this cylinder was connected to a plate and a grid for the exhaust to pass through just beyond the turbine blades, the positively charged air would be accelerated through the turbine blades where it would recombine with the electrons from the cylinder and complete a circuit.. Another set of turbine blades just beyond could extract the heat generated by the flow of current at this grid. A generator driven by the turbine would generate additional electricity. If a set of compressor blades was attached to the inside of a funnel, and the positive voltage at the center was connected to the funnel and an insulated cone just beyond the focal point, the compressed air would pass through the focal point where some of it would be ionized and some of the ions trapped between the positive voltage on the funnel and the cone and held in the focal point by the magnetic field arranged parallel to the axis of the turbine. The positive charge would build up which would tend to trap some electrons. The electrons would try to escape towards the funnel or the cone but being much closer to the positive charge at the focal point might trap some of them for a while. The rush of compressed air into the focal would try to dislodge the trapped ions and electrons, but a strong enough voltage and magnetic field might hold the ions and electrons long enough for the temperature at the center to increase fast enough so that more air was ionized than stripped away by the comoressed air. The positive charge on the air would tend to increase the pressure and drive the system faster. If the inner housing was connected to the funnel and the positive voltage at the center,, the funnel would tend to ionize the air as it was being compressed and air ionized by the plasma would tend to increase the voltage of the inner housing which would increase the ionization of the air in the compressor funnel. . A number of accelerating processes would tend to increase the temperature and the voltage of the compressed air and drive the turbine at an accelerating rate. Another possibility is to put a high voltage arc acriss the air entering the turbine. Since it is spinning, the arc would create a disk of plasma that could trap the sunlight at the focal point. Multiple arcs might trap all of the sunlight if one disk is not dense enough.
With Optimization of Stirling Engines you would drastically increasing production by making every parabolic mirror producing energy from concentrated light: higher temperatures means more energetic conversion. Highest temperatures differentials means increased efficiency. You have the only patented technology to creating below 80°K in a small radius with a small portable device producing no vibrations and lasting +22 years, NASA approved.. SunPower's Stirling CryoCooler is the best solution in terms of energetic expenditure for creating a low temperature side in a fully optimized Stirling Engine. You could ask "THAT" MIT board advisory professor helping you creating a Molten Aluminium Heat storage for superheating air at ~950°C during night time bringing night hours production just halfway the daytime production. With inexpensive materials like Clay Graphite , Aluminium and Arduinos you could be able to bring the Kwh price to 0,02$ quite easily... Taking in count a lot of jobs and a good pay even.. Ask Mexico... they have plenty of desert. [No seriously ask Mexico]
PV is not low tech. You could cobble together some form of CSP using parts you could find in many many villages and districts in africa. You can't manufacture a PV in the same african village or district. You almost 100% guaranteed have to import the PV panel.
@@backtotheoldway6964 You are right. PV's are not low tech. But the installation and maintenance is not very complex. Therefore, in rural places, PV's in a simpel setting are preferable. But still there is the problem of storage. There is no easy solution to that problem. But accu's differ greatly in price and effect. Maybe a less expensive solution can be found.
Solar power needs a whole lot of light collecting surface. Better be something simple like a mirror than advanced electronics like PVs requiring environmentally damaging mining to produce. CSP is more efficient too.
well Thermal solar power have economies of scale. Also thermal solar power can store energy in thermal batteries. these batteries are much cheaper when done at large scale. Its economy feasible for Thermal solar power plant to have enough power storage for whole night. Pv power storage has to be done in lithium batteries which are expensive and not as reliable. Thermal batteries life span is just as long as the turbines if not longer. It not economical for PV to store much power. Pv are great for off the grid small scale sites which you do not need too much lithium batteries. In tropical climates solar pv can be use for peaker plants since A/c units ran at most during the day.
This is complete bull... higher temps means higher pressures because when you increase the temp of something you also increase the pressure of something which means more resistance to motion because the charged particles...that are tiny magnets...run into each other more which creates more heat because of friction... because you are forcing the particles closer together...solar panels work better when cooler... it's an extremely stupid decision to change the sun's potential energy into kenetic energy to do work that is not needed... you are intentionally decreasing the output kenetic energy because you are doing work with it because in order to do work takes energy...it makes it less efficient...here is an example...a furnace blower motor is being restricted because of a frozen AC evaporator coil and is not letting much air by it cause it is a block of ice... you check the amp draw on the blower motor with the doors on so you get a true reading and you get 5amps... normally it should be 10amps...only half of the air that normally can be moved is being moved...this is less work because you are throwing less air...but you are still giving the motor the same amount of current because the circuit is what determines how much current is sent to the capacitor... A capacitor builds up charge before it sends it to the motor... So you are still sending the same amount of current to the blower motor at all times... Your amp reading is less because you are only reading the amount of current that is doing work... The rest of the current is being turned directly into heat... the capacitor does not care if the motor is being restricted or if the motor is pushing more air... So you lose efficiency because you're giving the motor too much energy to run it at the restricted speed.. so restrictions mean wasted energy.. if you look at the back of the solar panels in this video you will see a lot of copper on the back. Now look at solar panels for houses and you'll see that there is much less copper on residential solar panels.... That is how this thing makes more energy... Heating up a fluid is just wasting energy because you do not need to do that because you have solar panels that turns the sun's light directly to electricity...it's pretty stupid to have solar panels and use the electricity to turn a turbine to generate electricity
What you're missing is PV solar only "works" if you have storage. So you have to factor that into your equations here. Charging batteries is lossy too. Batteries are also very expensive by comparison per Wh.
I wonder how well the ceramic particles Mr. Ho and his associates have tested can store thermal energy that's not directly from sunlight.

if the bird decide to stand in the middle,what happen?
very accurate plans for something like that I found on Avasva

I thought parabolic solar condensers were better because birds aren't going to fly into it
Salut ca va
oui et toi ?
Ca va trql tfk
bah rien et toi ?
a ok
Salut ça va et toi

Why not stick to cheap low tech pv? It does the job low cost on your own roof.
PierreB yes, if you can find a cheap utility scale battery

It’s pretty basic physics that heat engines in general and steam turbines in particular operate more efficiently in higher temperatures.
