Has anybody ever tried putting their MMC under oil, or with a fan blowing on
them to keep them cool? It would be interesting to build two identical MMCs,
place one under oil or use some other form of cooling and leave the other
just plain and then test the two to destruction. I'm willing to bet that the
cooled MMC would stand up at least a little better. You could probably just
do this with a single cap for each setup and it would be alot cheaper.
