Yeah because it is still in development but it can be experimented with by anyone as he shares all the details. I imagined applying it to a sheet of metal and sitting that in the window so the heat is reflected but the plate will be cool. I haven’t experimented with it myself so I can’t say it would work. Just an idea.
It’s so interesting to me because this is the only way I have seen to cool below ambient without power.
