“When Nebia woos investors, it invites them to take a shower.” Good line from The New York Times. The start-up says that its revolutionary shower head uses six gallons for an average shower compared to the usual 20 gallons. And, according to reports from users who have tested the shower, the experience is better. Apple’s Tim Cook is one of the early investors. Nebia started a Kickstarter yesterday as well and aims to have a first batch of shower heads by next spring.
