I'm new to this community.
I have an idea regarding a more efficient solar powered renewable energy solution.
Note that current solar panel technology is roughly 2% efficient. I propose the use of magnifying lenses to concentrate sunlight, direct the laser's heat toward a liquid, and then use the liquid's subsequent molecular excitement to move other items that might, say, charge a battery. (Think of a wind turbine that is, rather than being turned by open air currents, is turned by a circulating, closed system of heated liquid or gas.) Now, many questions remain: what liquid to use? is the liquid's excitement harnessed as the pressure of steam (pneumatic) or in some other manner (perhaps hydraulic)? would it be best to use one large magnifying lens or many medium-sized ones?
I am seeking answers and suggestions. Thank you for your time.
