This is the new Mazda Kiyora, a concept car that is not only designed to consume less gas and produce less emissions, but to collect and purify the most important liquid on Earth: Water. You know, for drinking. If you are into that kind of liquid, anyway. When you drive the Mazda Kiyora through rain, its roof channels the falling water into a specially-designed Lifesaver purification bottle. The bottle, called Lifesaver Bottle Citi, is placed in the middle of the car's interior, between the front seats, for easy access by all passengers.

If you've ever thought of your light bulb as a serious underachiever without enough features, maybe it's time to spring for Viatek's new Ionic 15 watt compact fluorescent. This bulb pulls double duty, both brightening up your life and cleansing the air, all the while saving you money on your electric bill. The CFL uses 15 watts to produce the same amount of light as a 60 watt incandescent, lasts for 10,000 hours, and cleans a 100 square foot area with its built in ionic purifier. All for just US$14.99 on Amazon. Now repeat after me - lazy light bulbs are for losers! [Amazon via Popgadget]

Caught for the first time on video, Segway inventor Dean Kamen presented his Vapor Compression Distiller on last night's Colbert Report. The distiller is a chemical-, membrane-, and filter-free water purifier. Kamen claims the box draws pure drinkable water from oceans, poisons—even a 50-gallon drum of urine. He has reportedly worked on the contraption for five years, but early prototypes were pretty ugly. This one looks ready for mass production, and with enough, Kamen says we could "wipe out 50% of human disease." Good luck with that, Deano, we're behind you all the way. (That other 50% must be a monumental bitch.) [Colbert Nation]

If you have a phobia regarding your drinking water, this BottomsUp concept may be right up your alley. All you need to do is screw the filter onto any standard PET bottle and the water that emerges on the other side should be nice and clean. You can also attach a PET bottle on either end for an easy transfer. Something tells me that this idea is good enough to become a reality—my only question is, what the hell is in that bottle on the right? Additional picture after the break.

The Life Saver water bottle is a military grade water sanitizer that can make the dirtiest of water drinkable in seconds. The bottle not only filters out bacteria, but also takes care of viruses and water that has been contaminated by fecal matter. The creator, Michael Pritchard, initially came up with the idea after watching victims of Hurricane Katrina and the 2004 tsunami in Asia go for days without receiving clean water. There are others, however, that are interested in Pritchard's invention.

After showing the bottle off at a defence conference in the UK, Pritchard sold all 1,000 of his $385 bottles in under four hours. Defense experts were impressed with the fact that it could filter 4,000 or 6,000 liters before the filter had to be replaced. An innovation such as this could have a significant impact if it ever reached the consumer market, not only being used as emergency gear, but for camping and travel as well. [The Register]

Not only does this IonFlow 50F Air Purifier claim to rid your home of 99% of airborne pollutants, it's got blue LEDs and a design style that matches up with anything George Lucas's people came up with for the Star Wars movies. The only downside to this this is the $495 pricetag and the fact that ionizers may or may not work, create ozone, and may make your asthma worse. But hey, it sure looks fantastic. [DWR]
