Here’s a very good example of simple tech that works efficiently. Because hot air rises, cool air falls down. So if chilled water is carried through tubes at the ceiling, it sucks hot air from a room; sending down the cooler air. Simple tech is often low carbon technology too.
We’re all familiar with the vast solar thermal power stations in the desert that use mirrors to make steam to drive turbines. Giant solar thermal arrays are already making electricity in the desert in Spain and California. But what if we could have just one of these units in the backyard, just for our own use?
That’s what motivated a team of MIT students to find the way to make the cheapest solar power station out there. Mass produce it for the home user and market it under their own new start up RawSolar.
Sure, it melts steel. But even more practically for the home owner, it makes steam in a flash:

If you live in one of the states now sweltering through heat waves; even more frequent sweltering days are in your future as a result of climate change.
But it’s not only your children’s children who will suffer heat waves more often. Your property values in these states will also sink over time as your neighborhoods heat up to unlivable levels over the next decades.
A/C will be a necessity. But adding a heat recovery system will at least cut those losses to your home values:

Is Al Costa pulling our leg? The CEO of Delaware-based Alkol Inc. says he has a system that will convert your car to run on E85 in about an hour.
“Flexing” your vehicle with the Alkol conversion system will allow you to use one of those high-ethanol pumps, which contain a mix of 85 percent ethanol, as opposed to the normal 10 percent mix in conventional gasoline. You won’t need a brand new shiny vehicle with one of those “Flex Fuel” badges either.
How does it work? Does it work? Is it like one of those quick-fix radiator sealer bottles that high school kids used to pour into their old jalopies?
The economy is down, but here is another sign that green technology may be the way out of our economic dilemma. US clean energy patents hit a record high last quarter.

If you want to cut your carbon footprint, you can ride your bike a little more. If you want to cut it even further (from all that exhaling while pedaling), meet the EniCycle. This one-wheeled ride has a range of just under 19 miles on a charge. But it recharges when you ride it downhill (if you dare).
Labor Day will soon be upon us, and with it, the unofficial end of summer. Back to school time. Summer is the season for camping, getting out of the city and getting a little dirty in the woods. Some folks like to tent it. Some folks like a travel trailer, with their own bathroom (my wife included).
But one problem with campers is how much they weigh, the large vehicles needed to tow them and frequent trips to the gas station. Travel trailers are getting lighter and lighter, however, and easier and more affordable to pull. Take a look at the latest entry, from EverGreen (like the tree) in Middlebury, Indiana.

Editor’s Note: Michael Brito is a social media strategist at Intel. You can find him roaming the intrawebs on Twitter, Facebook or his social media blog.
Climate change is upon us, indeed; no need to argue that point. But how on Earth are we supposed to react to its affect on food production, water resources, ecosystems, energy demand, insurance costs, etc? Current research suggests that the Earth will warm over the next century and the rate of warming is steadily increasing. So the question needs to be asked, “What are we doing to prepare ourselves for these changes and how can people easily get involved in affecting positive change?”
Recently, Intel officially launched Progress Thru Processors; a new Facebook application that uses idle PC processor power for projects that are geared toward life changing research such as finding cures for deadly diseases and combating climate change.
The summer of 2009 has been cooler than usual in the Midwest, but Mother Nature can still pack a punch.
August has seen some 90-degree days in places like Michigan.
When it get this hot, some people like to stay inside in front of the air conditioner (based on recent Twitter and Facebook updates). But it doesn’t have to be this way.
The air conditioner, I mean.
A “whole house fan” that uses the attic for venting can keep your home cool with less electricity (and for less money) than modern-day air conditioning. Read the rest of this entry »
You know the drill. You flush the toilet, walk away, come back later and it’s still running.
You jiggle the handle. Hopefully that makes it stop. Maybe you take off the top of the tank and swear a little.
Or, you could install H2Orb, a toilet gadget from a California company that takes clean tech to a whole new level. Read the rest of this entry »
