Yes, I know it is similar to Factorization's Solar power system. But hey, in reality these solar towers do exist that's why I thought it would fit nicely in the mod since they're going for realistic things now.
Yes it would take up a very big space but if you want to get a decent amount of energy from the array solar panels it requires a very big space as well so same thing. But I like the idea. 'Solar Heat Absorber' blocks which would be built up in an array.
As for heat. I was also thinking on heat generation but think it over. Since there are no heat conducting cables you have to generate and use the heat directly next to the machine that requires it. Now, a solar plant like this would be outside your base since it needs a large space because of the array blocks and it needs to see the sun. It would be a bit uncomfortable to put the machines around the plant to use the heat I think. Now this could be solved using steam in my opinion. The array do generate heat units but by putting water inside the system the heat would be used up to turn the water into steam. Steam acts as a fluid so you could transport it and use it in steam turbines. Or coolant could also solve this thing just like in the pressure vessel reactor.
I think a system like this would not be a too easy solution for energy gaining. You need the array blocks, the turbines, a pump to inject water into the system and you also need to solve the transporting of steam. But It could be more complex and harder by calcification and by the need of distilled water.
