The United States National Laboratory Of Water Drinking And Health (not a real laboratory) recommends that all humans drink lots of water all the time. That’s why H2O-Pal exists – it’s a water bottle that tells you how much you’ve drunk and, more important, when you’ve reached the daily goal of two to five gallons (warning: you could probably drink less) needed to stay alive.
The system uses a scale and accelerometer to see how much water you drink during the day. You fill the bottle, snap on the electronics, and hit the town. You can pull the puck-like device off of the bottle for washing. It then connects to your iPhone via Bluetooth to report your drinking habits.http://www.kickstarter.com/projects/outofgalaxy/h2o-pal-the-perfect-solution-to-monitor-your-water
They are asking for $95,000 on Kickstarter with devices starting at $59. They will sell for $69 when H2O-Pal launches in February. The Ljubljana-based company showed me prototypes of the system last summer and I was duly impressed. Anything that can ensure that we liquid-based lifeforms maintain our juiciness is A-OK in my book.
