Six Seriously Geeky Developments Get USDOE Funding


The US Department of Energy recently awarded funding to six programs for a total of buy now online cialis $9.6 million in funding under the department's Advanced Research Projects Agency-Energy (ARPA-E) program. Three of the six projects received funding of over 2 million dollars apiece. The other three each received an amount between one-half and three-quarters of a million dollars. Each of these programs offers the potential for significant advances in their respective fields.

"By investing in transformative ideas now, we are laying the foundation for a new clean energy future," said Secretary of Energy Steven Chu. "The ARPA-E program is helping to ensure U.S. leadership in science and technology, restore our global competitiveness, and create thousands of jobs."

The major projects are for an airborne wind turbine from Makani Power, a nanostructured permanent magnet from GE Global Research, and a supercritical fluid thermal energy storage system from UCLA. Makani Power's airborne turbine is a tethered wing used for power generation at significantly lower cost than conventional horizontal-axis wind turbines. GE's nanostructured magnets would reduce the need for critical rare-earth elements and provide increased performance for electric machines including hybrid vehicles and wind generators. UCLA's supercritical fluid thermal energy storage system would replace current two-tank molten salt storage used at solar thermal power plants with a supercritical fluid that would double energy density and cost less than 70 percent of the cost of current systems. The minor projects are for a nanotechnology membrane-based dehumidifier to dehumidify moist air with a polymer that is air permeable but not moisture permeable, a cryogenic carbon capture system for flue gasses, and an optofluidic solar tracking concentrator.

Yahoo Unveils Super Efficient Data Center

It was just a little over a year ago that Yahoo announced it was building a super-effiicient data center in Lockport, NY - one that would be powered by Niagara Falls.  Just this week, the company unveiled the finished product.

The Lockport facility will indeed be powered by Niagara Falls hydropower, but the impressive part of the data center is cheap tramadol no prescription 180ct the efficient design.  Called the levitra in uk Yahoo Computing Coop, the facility was modeled after a chicken coop, with long, narrow buildings that encourage re-circulation of Lockport's cool air.  Between the cool climate and the efficient design, the data center will only use one percent of the energy it requires annually on cooling.  That is a very significant reduction as most traditional data centers use upwards of 50 percent of energy demand on we like it levitra on women cooling.

Here are some more numbers.  The data center will use 40 percent less energy and at least 95 percent less water than a conventional data center.  The energy saved is roughly equivalent to generic levitra mastercard the electricity used by 9,000 NY houses each year and the water saved is equal to the amount that flows over Niagara Falls each minute (about 4 million cubic feet's worth).

Yahoo owes most of the credit to the Lockport location:  the cool climate, regular winds and proximity to ample hydropower.  But the company capitalized on those things with a smart design and use of more efficient technology, something that other tech companies could easily replicate.

Piston-Powered Airplanes More Fuel Efficient (But Is That Enough?)


A recent article from Low-Tech Magazine brings up the interesting note that only the most recent jet planes are as fuel-efficient as propeller planes. Many people believe that jets are very efficient, but, "on a per passenger mile basis, the most efficient modern aircraft, the Airbus A380, has just managed to match that which was achieved by the viagra without prescription piston engined Lockheed Constellation series in the 1950's."

Unfortunately, passenger-mile fuel efficiency isn't the sole metric that airlines have to consider. Fuel cost is certainly a big chunk of the operating budget for a passenger plane, but so is the cost of where to get cialis crew wages and benefits. Jets travel faster, better utilizing the working hours available for each flight crew. Piston aircraft may be more fuel efficient, but there are other things that jets do better.

Piston aircraft cannot operate at the higher altitudes that jets can reach. The Constellation's ceiling was 24,000 feet (7,315 meters), while contemporary jets can reach an altitude of about 40,000 feet (12,192 meters). Flying at higher altitudes allows jet aircraft to avoid weather systems that would delay or halt aircraft operating at lower altitudes.

None of this means that we are in favor of retaining the status quo. While jets can fly higher, they also release their exhaust higher in the atmosphere, which is likely more damaging than exhaust released at ground level. The environmental costs of any form of air travel are not fully incorporated into the costs to canadian healthcare pharmacy consumers. Both technologies should continue to be developed, and we've also seen hybrid propeller-turbines, which are intriguing, too.


Will Incandescent Bulbs Go Away?


The "last major GE factory making ordinary incandescent bulbs in the United States" is set to close later this month. Most incandescent bulbs will be banned from sale in the US in 2014, and many other contries have enacted similar bans on incandescent bulbs within the next few years, as well. But while the cialis prescription deadline has been set, and the manufacture of incandescent bulbs is set to end in a couple of years, there is a growing market for specialty incandescent bulbs.

Against all reason though, bare filament light bulbs are spreading as a trendy fashion in restaurants, as was noted in the New York Times earlier this summer:

...they hover in groups of two and three. ...they snake through the cafe, restaurant and patio. ...they cluster near the entrance as an enticement.
They are not the latest cliques of beautiful people, but something quite old and plain: exposed-filament bulbs, energy-guzzling reproductions of Thomas Alva Edison’s first light bulb. And despite the escalating push to go green and switch to compact fluorescents — or perhaps because of it — their antique glow has spread like a power surge.

Incandescent bulbs are like fireplaces, a vestigial remnant from an earlier time. They can be appealing, certainly. For some they are a symbol of luxury, but they are wildly less efficient than contemporary alternatives. While they may contribute to the ambience of a space, their operating costs are huge, and much of buy kamagra the desired effect can be obtained from other sources, without resorting to the use of a lapsed technology.

If you are looking for a warm, romantic, old-fashioned light source, you might consider the suggestion of one enlightened restaurant owner: "Just light real candles, you know?"

Color Filter Could Boost LCD Efficiency by 400%

Researchers at the University of Michigan have created a color filter that could boost the efficiency of LCDs, the power hog of all your gadgets, by more than 400 percent, and no, I didn't add an extra zero there.

The researchers made an optical film that colors and polarizes the buying generic viagra light that passes through an LCD, taking the place of the several layers of optical devices that typically serve the same function in an LCD.  Those multiple layers give rise to pharmacy levitra inefficiencies:  the best LCDs out today only emit eight percent of the light their backlights produce. The researchers found that the film allowed 36 percent of the light to make it through - a huge increase.

The color filter is made up of levitra for sale three ultra-thin layers -- two layers of aluminum enclosing a layer of insulating material -- and it only measures 200 nanometers thick.  The filter is etched with slits that produce different colors when illuminated by the backlight.  The slits are matched in scale to the wavelength of visible light and their length and distance apart determine the color produced.

This grating pattern is where the efficiency boost comes in.  In current LCDs, a polarizing filter absorbs half the light (the part with the we like it order levitra now wrong polarization).  The grating on the new filter doesn't absorb the light with the wrong polarization, it instead reflects it back towards a mirror that flips some of its polarization, letting more light pass through the filter.

Researchers are trying to improve the efficiency further and are coming up with ways to mass produce the filters, like with roll-to-roll printers.
