I watch hundreds of those black insulated molten sulfur tanker cars go buy on many of the trains here in Wisconsin. I think people think they're full of oil or something.
Just tell them they are filled with jellied gasoline and see what they say.
I can't think of a reason to use He in a hard drive other than the fact that it's non-reactive, and couldn't they use Argon?
Modern hard drives store data on five metal platters that spin at up to 15,000 revolutions per minute, so fast in fact that drag from the tiny amount of air they whistle through is a problem. But at one-seventh the density of air, helium provides far less resistance for those spinning disks, letting the company pack in more disks that require less power and therefore cost less to operate.
Yeah, forget about chemical plants, do people really realize all the chemicals that travel across the nation every day in trucks and rail cars? Maybe I shouldn't tell them.
