nuclear fusion
"Someone said that nuclear fusion is like to put the sun in a box. But right now we don't know how to make the box."
"Nuclear fusion is like high velocity atom smashers or manned space flight: it eats government science budgets"
"Nuclear fusion is like hitting a bottle full of nitroglycerin and hitting it with a hammer you only have to put little bit of energy in but you a ton make the problem is harnessing that energy being released."
"Nuclear fusion is like mountains. It take a lot more power to lift the ball over the next mountain top, but the distance to the bottom is massive and the return on your effort is equally massive, much more than the fission hills."

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
