Heat from Commuters in Stockholm’s Central Station Serves Nearby Office Block

Swedish ngineers have found a way to recover the excess heat generated by commuters in Stockholm’s main train station and use that energy to heat a nearby office block.

The technology is not all that different from typical heat exchangers … this application is well suited to climates like Sweden where the winters are quite cold and the cost of petroleum based fuels is quite high.

Check out this video of more details …

Opposed-Piston Opposed-Cylinder Engine
EPOC Engine Layout
EcoMotors International has developed the OPOC engine - opposed-piston opposed-cylinder engine.  This engine can run on a number of fuels and is lighter in weight and produces more power than a conventional engine.

The basic engine "unit" has 2 pistons per cylinder and multiple "units" can be coupled for a more powerful engine - or one or more "units" can be turned off at idle or during highway speeds.

" ... demonstrate, in 2010, the automobile industry's first 5-passenger car capable of 100 mpg on the EPA highway cycle."

" ... ground-breaking internal combustion engine ... eliminates the cylinder-head and valve-train components ... lighter, more efficient and economical, with lower exhaust emissions compared with conventional designs...."

IBM's Water Cooled Aquasar Technology Reduces Carbon Footprint

IBM has developed a water cooled supercomputer that uses the extracted heat to heat a building.  Normally A/C is needed to remove the excess heat to prevent damage to computer systems.

The A/C to remove heat can use almost as much or more energy than that used to power the computers ... resulting in lots of wasted energy and extra carbon footprint  What a waste !!Aquasar - Graphic from TechRepublic

" ... Aquasar, consumes up to 40 percent less energy than a comparable air-cooled machine. ... carbon footprint is reduced by up to 85 percent."

Google - Leads in Energy Efficient Data Centers



Google has been at the forefront of energy efficiency quite some time.  They recently were written up for their large rooftop solar array.  Google has lots of data and metrics to determine the average energy "impact" per search.

Read on to learn more about Google current initiatives.

" ... Data centers ... account for most of Google’s energy needs ... take our energy use seriously and, from the very beginning, Google has focused on designing systems that use as little energy as possible ... operating what we believe to be the world's most efficient data centers."

" ... Google-designed data centers use about half the energy of a typical data center ... energy used per Google search is very small ... currently use about 1kJ (0.0003 kWh) of energy to answer the average query ... roughly .2g of CO2 ... often take the place of more carbon- and time-intensive activities, such as driving a car to a library or spending hours navigating shopping malls."

" ... commitment to sustainability goes beyond just electricity and carbon ... two Google

facilities currently run on 100% recycled water, and by 2010 we expect recycled water to provide 80% of our total data center water consumption ... share our own data center best practices and are encouraging our industry peers to do the same ..."

" ... if all data centers operated at the same efficiency as ours, the U.S. alone would save enough electricity to power every household within the city limits of Atlanta, Los Angeles, Chicago, and Washington, D.C."

Home Fuel Cells Coming to Japan



" ... Matsushita ... will claim first place in the race to put commercial home fuel cells on the market ... "

" ... can optimally provide 70 percent of the energy needs for a 1,280 square foot house with four people ... can reduce energy consumption by 22 percent and CO2 emissions by 12 percent as compared to all other power sources ... ".

" ... in this case, the cogeneration home fuel cell hooks up to the city’s natural gas lines, extracting hydrogen from the gas in a fuel-processing device ... hydrogen is combined with oxygen through a series of polyelectrolyte membranes, a process that creates electricity, heat, and water ... home fuel cell produces between 500 watts and a 1 kilowatt of electricity and captures the heat to warm a tank of water, used for showers, dishes etc."

" ... a contribution to Japan’s goals of reducing global CO2 emissions 50 percent by 2050."

" ... fuel cells require a great deal of energy; for example, this unit contains more than 2,000 components. Whether the production of the units negates the energy and CO2 savings gained by customers is unclear."

Efficiency Stickers for Buildings


Here is an interesting idea ... what if buildings came with carbon stickers .. much like cars that have mpg and emissions stickers.  Such a mechanism would allow for consumers to shop for the more environmentally friendly building.

" ... every car has a sticker that tells you its fuel consumption ...sticker is also an effective policy mechanism for controlling the overall fuel consumption of all cars, and hence their carbon emissions ... "

"Why don't we do the same for buildings? Buildings account for around 40% of total carbon emissions in North America, while SUVs account for just 3%. Imagine the impact if we could put an efficiency sticker on buildings and halve their emissions over 10 years. Cutting building emissions in half would save 1.14 billion tons of carbon in the U.S. in one year alone."

"We know very little about the energy efficiency of our buildings, and there is no overall benchmark for building performance. ... we don't have a policy lever to reduce building carbon emissions the way we can with cars."

Follow the link below to read the full story ... a very intersting and worthwhile copncept.

What do you think ?

US Department of Energy L Prize (L = Lighting)


The US Department of Energy is sponsoring a competition, the L Prize Competition, to build a better lightbulb.  The 60 Watt incandescent replacement will use less than 10 Watts

" ... competition will substantially accelerate America's shift from inefficient, dated lighting products to innovative, high-performance products. ... the L Prize will drive innovation and market adoption. ...

is the first government-sponsored technology competition designed to spur lighting manufacturers to develop high-quality, high-efficiency solid-state lighting products to replace the common light bulb."

"If every socket in the U.S. converted their 60W incandescent lamps to the 10 W L Prize winner, the country would save approximately 34.0 Terawatt-hours of electricity in one year, and avoid 5.6 million metric tons of carbon emissions.... enough electricity to power the lights of 17.4 million U.S. households, or nearly twice the annual electricity consumption of the city of Las Vegas."
