Lowering the Costs of Concentrating Solar Power


Concentrating solar power uses the sun’s rays to create thermal energy that is used to produce electricity, then store it for use when it’s needed. A SunShot Initiative project with Sandia National Laboratories is perfecting new technology that allows heat to be stored at higher temperatures, improving the efficiency of concentrating solar power plants and allowing utilities to provide customers with clean energy even after the sun has set.

    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
