Like it or not, at least for the near future most of us are stuck with internal combustion engine powered cars. While a lot of hype is behind future cars and technology, from electric to hydrogen to everything in between, a lot of improvements can yet be made on the ICE engine.
To that end, the Department of Energy has awarded GM with $2.7 million to develop a working prototype of a Shape Memory Alloy engine. In theory, this engine could recycle the waste heat and turn it into electrical energy, perhaps one day even replacing alternators and improving fuel efficiency.

Our kids will go through ice pops like water in the summer… well, let me restate that, they will eat as many as I will let them regardless of the weather outside.
During the hot days of summer, I want them to stay hydrated and I also want them to get good nutrition. We are drinking lots of flavor infused water and gobbling up all kinds of frozen creations.
We like commercial molds because they contain all the necessary pieces and use a smaller space in the freezer. However, ice cube trays & cups work well also. For reusable “sticks” opt for plastic spoons or other easy to clean item. We go through about 24 a day so I just toss things into the blender until its full, leftovers can be a nighttime snack!
Make a bunch every night, this is a good post dinner/before bed activity. The kids love to choose the ingredients and help mix everything up. There are a few simple ways to go about this…

German car giant BMW has announced plans to attach radioactive heat-collectors to the tailpipes of future models, in a move predicted to slash fuel use and reduce carbon emissions by around 5 per cent.
The massive fuel saving is bigger than the three per cent achieved by the two current key Efficient Dynamics technologies - stop-start and brake energy regeneration.
The revolutionary technology, originally designed to power space satellites, captures waste heat transferred down the tailpipe and converts it to electricity via a radioactive ‘thermolelectric generator.’

A Swedish town announced last month that it will use cremated bodies to provide heat, and now the British town of Reepham has decided to heat many of its buildings by burning oil made from melted cow and pig carcasses. Are dead bodies— human or otherwise— the next big thing in heating?

Millions of people around the world heat their homes with charcoal burned on small grills. Now a group of Japanese scientists has developed a biomass charcoal combustion heater with a thermal efficiency of 60-81 percent— a big step up from current biomass stoves, which have an efficiency of 46-53 percent.

Australia’s federal government, led by Prime Minister Kevin Rudd, has approved plans for a $60 million dollar factory which is to become the largest manufacturer of solar cells in the Southern Hemisphere.
The company responsible for the project, Solar Spark Australia, is the first to be awarded Major Project Facillitation status under the Rudd government, and it plans to begin powering 9,000 homes by late next year.
This marks increased hope that Australia can meet goals to reduce greenhouse gas emissions 60% by 2050.

The biogas process, which produces fuel from animal and human waste, is prompting many supposedly amusing posts that could have a negative effect. Googling “biogas and poop” gives 12 800 hits including The Power of Poop, California Cow Poop Power and Turning Cow Poop into Car Power. This is counter productive as it distracts from the potential that biogas holds for both developing and developed countries.
Besides the comical slant of the titles, it is surprising that biogas is often presented as something amazing & unknown although it has been around for hundreds of years, is used in tens of millions of rural household and is a significant contributor to Europe’s renewable energy production.
Biogas - Amazing Natural Technology
The fermentation of organic material such as biomass, manure, sewage, farm waste, municipal waste, green waste and energy crops in the absence of air produces biogas. The same anaerobic fermentation produces swamp, marsh and landfill methane.

Kids can earn some green by doing what they love, creating thought-provoking media on climate change!
For the first time ever, kids are ‘burnin’ down the house’ with ideas and innovation to pitch renowned PBS hub WGHB for 3 to 5 minute youth videos on how climate change affects kids’ own community environs, vying for $2000 production grants and potential PBS airing.
WGBH has made it even hotter for green teens by hosting ongoing webinars starting Feb. 3rd to help kids conceptualize, remix, pitch ideas and amass public opinion…(accessible via archive too, so don’t sweat the date)
Popular pioneer vloggers Ryanne Hodson (who I can attest is very generous with her knowledge, as I’ve attended her Media Center how-tos and checked out her book) and Jay Dedman (her partner, former CNN journalist/co-founder of Yahoo’s videoblogging group) will contribute their skill sets to get kids started. Partner org Teachers Domain makes it a cinch for students to get up to speed with factoids and resources too. The inspiration for the contest? The Frontline documentary, “Heat” all about global warming and businesses’ reactions in the court of public opinion contributing to make or break success. Deadline for entries at WBGH is March 15, 2009. Next up on the eco-competitions…

Harnessing the Earth’s Heat for Food and Power
As the rumbling temblors beneath Yellowstone National Park continue (over 900 hundred such weak quakes in 2008), media attention shifts to two topics: the possibility of a super-volcanic eruption (not likely, according to most geologists), and secondly, the harnessing of geothermal energy.
This latter consideration is all the more fashionable these days as America struggles to embrace an alternative and sustainable energy future.
Geothermal energy offers the promise of a virtually unlimited source of power. Although less energetic in terms of total constant power output compared to the sun, harnessing the geothermal venting from a single, sufficiently high-grade, hot-spring could conceivably provide power for a population of tens of thousands, and it’s not weather dependent. But there are also plenty of “lower grade” springs that can be put to other uses, such as growing hothouse produce (and the spring water is also used for watering the plants) and naturally warming water for fish farming (the Talipia species, a popular dinner fish, is one species farmed this way). Not all animals that are farmed this way are used for food, some, like the farmed alligators in Mosca, CO (see photo), are raised for their skins primarily (though some do eat the meat).

They say that necessity is the mother of all invention. In the Gaza Strip, due to the restrictions placed by Israel, one Gazan engineer has developed a solar oven that uses the abundant supply of sunlight to cook food.

Editor’s Note: This post was provided by one of our paid sponsors, Chimneyballoon. Stop heat and AC from escaping through your fireplace or woodburner chimney with a Chimney Balloon fireplace plug draft stopper.
On a cold winter evening, who of us is not tempted to go to the living room, stoke up a fire in the fireplace, and read a book in front of the hearth? You may be thinking “I am doing myself a favor by supplementing the furnace with additional heat”. But there’s a dark secret about your fireplace: you are making your house colder, and could be contributing significantly to pollution depending upon how you burn. Fireplaces can be monstrous energy eaters!
The wood burning fireplace is an “Energy Eater”
The air action that a wood-burning fireplace initiates in our home is wasteful. The second the damper is opened, heated air begins pouring out of the top of the chimney. As the fire in the hearth accelerates, the combustion process grabs already-heated air from your home and burns the oxygen and combustible gasses in it. The heat that is created in this combustion quickly rises and grabs more heated inside air and tosses it up the chimney. You can restrict the amount of inside air that the fireplace has access to by installing glass doors, but this will also severely limit the amount of radiant heat that fireplace can cast forward into your living space. This radiant heat is the heat you feel on your skin in front of the fireplace, and is the only usable heat that the fireplace will produce since the combustion heat is pouring out the top of the chimney. In the meantime the home is drawing in cold outside air from other places (i.e. windows, light sockets, doors, etc) to replace the air that is escaping the home through the chimney. This is referred to as the “stack effect.”
