Real JetPacks are for sale right now. Popular Mechanic has revealed their tests of JetPacks in their July issue. The Tam Rocket Belt costs $250k, flies for 30 seconds and has a top speed of over 60mph. The JetPack H202 goes 70 mph, flies 33 seconds and is a bargain at $155k. Both weigh over 100 pounds, include lessons with the purchase price and are powered by hydrogen peroxide. Keep the H2O2 (hydrogen peroxide) away from your skin.

Next year, Jet Pack International will release a model with 19 minutes of flight that runs on Jet-A fuel.

A device that mimics the naturally disinfecting quality of fresh air could be used to purge hospital wards of superbugs, its makers claim.

The Air Disinfector, launched in London, UK, on 19 June pumps a continual stream of reactive hydrogen radicals into the atmosphere, killing microbes within minutes.

"The same results could be obtained simply by opening all the windows of hospital wards, but that’s not practical," says David Macdonald, co-inventor of the device and chief scientific officer of Inov8 Science, which developed it.

Macdonald and co-inventor Derek Elwood identified the so-called open-air factor phenomenon more than 15 years ago through experiments at the UK government’s chemical and biological defence labs at Porton Down in Wiltshire. They established that outdoors, microbes are killed by hydroxyl radicals, highly reactive agents constantly produced through natural reactions between airborne ozone and organic scented chemicals from plants such as pine trees.

A low energy light bulb is always appreciated. Yet, as a certain show on the Discovery Channel (MythBusters) pointed out the conventional light bulb still did fairly well on the energy scale as opposed to the "energy saving" ones. Now, Imagine this, a low energy light bulb that can hang on your wall like a picture frame?

You’ve seen these before right? At the mall with all sorts of relaxing water sounds and pictures? Ha, no that’s not it. It’s actually aluminum foil made to act like a light  bulb,  by a neat process (see below). Not only that, it can be mounted onto curved spaces and even take on different hues depending on the gas.

So are you tired of your conventional, Stone Age lamps yet? If you are, just reach in your ‘fridge for the nearest used foil, nail it to your wall, infuse some hydrogen, get some electricity flowing through that sucker and viola! Well….That’s not totally true, you better just wait for the product to come out.

It wasn’t too long ago that next-generation taxis were being demoed at the NY International Automobile Show, but unless those roadsters sport gas sipping hybrid engines, they won’t survive past 2012 in the Big Apple. Reportedly, New York Mayor Michael Bloomberg has ordered that every last one of NY’s taxis operate on hybrid engines by 2012 as a part of an obvious plan to reduce emissions in the state. Once the transition is complete, Bloomberg noted that it would be the "largest, cleanest fleet of taxis anywhere on the planet," but considering that only 375 of the approximate 13,000 licensed taxis are currently in compliance, we’d say they’ve got a long ways to go. Currently, NYC has approved nine gasoline-electric hybrid vehicles for use as taxis, and while it has yet to be set in stone, officials are purportedly looking into extending the hybrid initiative to encompass garbage trucks and buses.

New York may look like they are leading the green public transportation revolution, but Los Angeles has had hydrogen only buses for years now.
