The monetary density of things
People have been saying that the new industrial grade swimsuits like the LZR Racer are worth their weight in gold. As you can see, this is clearly inaccurate. But such a suit is worth its weight in marijuana or industrial diamonds.
At the high end of this graph is gold (the only thing worth exactly its own weight in gold!), right next to the cost of launching a pound of stuff to low earth orbit on the ISS. Putting that into perspective here: You might as well build your whole spaceship out of $20 bills-- it still would cost less than putting it up there. It could almost be made of solid gold for that price.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
