All the lobster you can eat…the Fox Islands. Yum! Spooling up a stationary steam turbine if kept in the standby mode only takes a few hours at most, and a lot of that is based on how much load you’re going to expect out of it once it comes online. That is, they could easily maintain the

The boiling point of sodium is more than 1600F so the energy stored in the liquid sodium would be enough to keep boiling water to make steam for a substantial period even after the sun went down.I would assume (dangerous of course) that the production of steam would be a 24 hour deal with the

Since the system is designed to focus sun energy into a solar furnace, the boiler portion of the system "should" be setting at operational temperature. [except on cloud cover days, of course]. Since sunset is a known event, safe presumption would be that prior to sunset, the steam pressure would

Well a 1200lb steam plant on a US Navy ship required about 24 hours to be brought online from stone cold, but that can be significantly shortened if you don't let it get stone cold.  I would imagine that they would figure a way to keep the steam side hot enough so very little time, like 30

Yeah those molten salts can hold a tremendous amount of heat in the heat of fusion but they are also quite corrosive, so there's that too. I have to remember those laws... 1. You can't win {\displaystyle \Delta U_{\rm {system}}=Q-W} 2. You can't break even \delta Q=T\,dS\,. 3. You can't

Correct. The premise is the liquid sodium [salt solution] is heated to a very high temperature and stored in a thermal container which holds the heat until release. During the heating day, the solution is circulated from the heating grid [sun collection device] to the container in continuous loop
