So, I’ve been thinking that the possibility of obtaining any usable amount of fuel for an RTG experiment is impossible while I’m still within the US borders... Fine! I just got another idea this afternoon. Instead of using the heat from the radioactive fuel, how about using the heat from a solar collector? http://www.livescience.com/technology/041115_solar_dish.html I’m pretty sure I could compete with the 1050° temp from an actual RTG by building something like this (for the moment).
