The kids at Philips have just announced something called InstantTrust,
a UV water purification system that heralds the first time water can
be disinfected instantly, efficiently and independent of water
temperature, according to the typically understated Dutch press
release. We can't pretend to fully understand how the technology works
exactly (something about using ultraviolet light to wreak havoc on a
microbe's DNA, which sounds pretty awesome) but we do know that clean
drinking water is incredibly important — and that up until now,
purifiers have been relatively slow, and you couldn't run hot water
through them. According to the company, the new system is small enough
to be embedded in household appliances, and it works independently of
water temperature
