radioisotope power systems used in outer-planetary missions, where solar panels would not yield enough energy. Efficiency is 6 % using 'thermoelectric couples', which show aging and thereby a further decrease in their efficiency.
A reading and discussion group, based around books that straddle the line between the popular and scientific. Roger Penrose, Stephen Hawking, Richard Feynman--Let's read them in depth and discuss. We will also take advantage of public lectures and discussions about the hard sciences.
