Drinking water purifiers pretty much have to remove/kill bacteria by some means to be effective, but Slingshot (Dean's purifier) isn't actually a filter system. Rather, it runs on vapor distillation. That means it removes bacteria ...and viruses, heavy metals, arsenic, chrome, any chemical waste or human waste... and produce pure, distilled (really) water at a through rate of about 1000L/day. Also creates about a net 1 kW/day with the Stirling. Amazing machine.
Cui's method may well be cheaper up-front, though. Dean's is pretty expensive, ~$1500 for Slingshot and ~$3700 for the Stirling, though it runs on literally anything that burns and anything that's wet. There are a few other really cool ones out there: like
Hydra, which is much more expensive and larger but fuel-less and produces almost 76
thousand liters/day along with hydrogen and oxygen. Lots of options on the horizon, thankfully.
Looks like it'll be a great show! Wonder if I can get the Science Channel in college here some how. (Science in college? whodathunk
)
