Need help developing an idea, solar energy heliostats

AI Thread Summary
The discussion focuses on the potential use of multiple heliostats to create two refraction points, with the second point directing solar energy downwards. The idea suggests that using multiple heliostats could magnify the beam at the second refraction point. There is curiosity about whether the beam could be effectively projected over long distances using a curved mirror or lens. Participants seek clarification on the mechanics of changing the beam's direction multiple times. Theoretical feasibility is acknowledged, but practical implementation details remain unclear.

So i was wondering could you use two helio stats so there was two refraction points, the second one focusing the beam of solar energy back downwards? If so could you use multiple helio stats to meet at refraction point # 2 magnifying the beam that's pointed downwards? In theory it should work correct? Also, could this beam be projected over long distances from refraction point #1 to #2 if focused correctly by a curved mirror/ helio stat or lens? In theory it should work, correct? I'm no physics major I could use any feedback. Thank you!

Can you provide a diagram of what you mean? Your description isn't entirely clear, are you changing the direction the beam is propogating in more than once?
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
