Whey Protein Transformed into Sustainable Food Packaging
Written by Megan Treacy on 01/09/11   

Whey protein, a milk protein that is a byproduct of cheese production, is often used in protein bars and good choice levitra online no prescription shakes, but scientists in Barcelona have discovered that it can also be made into a more sustainable plastic for food packaging.

The WheyLayer project was funded by the European Commission to buy cialis canada find an alternative to petroleum sources in food packaging.  Through this project, research company IRIS found that whey protein could replace synthetic petroleum-based polymers.  The whey protein plastic has similar oxygen-blocking properties to traditional food packaging, but it's cheaper to make and, even better, more easily recyclable.

Traditional plastic packaging is hard to recycle because the petroleum-based polymers are almost impossible to separate for individual recycling, but with the whey protein plastic, the whey can be removed with enzymes so that the levitra next day delivery remaining film can be recycled or reused in new packaging.

This process also keeps the 40 percent of whey protein discarded by European cheese factories out of landfills.

Using LCDs to Collect Energy
Written by Philip Proefrock on 30/08/11   

Keeping electronic devices powered is an ongoing concern, particularly as the number of electronic devices proliferates. Researchers at UCLA have developed a liquid crystal display (LCD) that incorporates photovoltaic polarizers that can convert sunlight, ambient light, and even its own backlight into electricity to real cialis without prescription power the device.

Polarizers are what makes the display in an LCD function, by controlling the amount of light that passes through from the backlight to make the visit web site cialis in india display. The new material, called a polarizing organic photovoltaic film increases the efficiency of propecia 5mg online display and allows for charging of the device in bright light.

Obviously, the backlight isn't going to provide enough light to power the device infinitely long. But the researchers say that much of the energy lost from backlights can be saved with the new polarizer. "From the point of view of energy use, current LCD polarizers are inefficient, the researchers said. A device's backlight can consume 80 to 90 percent of the device's power. But as much as 75 percent of the light generated is lost through the polarizers. A polarizing organic photovoltaic LCD could recover much of that unused energy."

Carbon Nanotubes Make Wind Turbine Blades Lighter and Stronger
Written by Megan Treacy on 30/08/11   

A scientist at Case Western Reserve University has discovered that adding carbon nanotubes to a traditional mix of plastics used in wind turbine blades could make them much lighter and stronger, meaning that future blades could be much more efficient while also requiring less maintenance.

The study found that carbon nanotubes are lighter per unit of volume than carbon fiber and aluminum and had five times more tensile strength than carbon fiber and 60 times more than aluminum.

If those carbon nanotubes are mixed with a polyurethane composite, the material lasts eight times longer than an epoxy reinforced with fiberglass and it was eight times stronger in fracture tests.  Compared to a vinyl ester reinforced with fiberglass (another material commonly used in wind turbine blades), the carbon nanotube material performed even better with far less fracture rates.

Panda Poo Could be Key to viagra mexico Cheaper, Cleaner Biofuels
Written by Megan Treacy on 29/08/11   

Scientists from Mississippi State University have discovered that panda poo could hold the answers to faster, cleaner and viagra cheap buy online cheaper biofuels.

It has long been suspected that animals like pandas that each giant amounts of sale viagra tough plant matter every day have bacteria in their digestive systems that are especially efficient at breaking down the cellulose in plants into nutrients. The hope is that those bacteria could make a big difference in the production of biofuels from tougher, non-food plants, like switchgrass, corn stalks and wood chips.  After collecting panda feces from the Memphis Zoo for over a year, researchers found that was definitely the cialis tadalafil case.

So far the scientists have identified several types of digestive bacteria from the feces. Some are similar to those found in termite feces, but the study has shown the bacteria in the panda feces could be even better at breaking down cellulose than those in termites.

Based on this study and others, the researchers believe that the panda gut bacteria could convert 95 percent of plant biomass into simple sugars.  The enzymes in this bacteria are so potent that they can eliminate the need for heat, acids or high pressure processes in the manufacture of biofuels. Eliminating those processes would make biofuel production less energy intensive, faster and, of course, cheaper.

Researchers are working on identifying every bacteria present in panda intestines in order to single out the most potent of the enzymes.  Those enzymes could be put into yeasts through genetic engineering, which would allow for the mass production of those enzymes for the biofuel industry.

Toyota and Ford Working Together on Hybrid SUV Drivetrain
Written by Megan Treacy on 25/08/11   

Toyota and Ford are partnering together to build a new hybrid drivetrain for SUVs and light trucks.  The two automakers, who've both been developing hybrid drivetrains for cars and SUVs separately for years, are hoping to make better advances in this particular sector by pooling their resources, both monetarily and technology-wise.

A statement from Toyota said the company wanted to work with Ford because of their leadership in producing SUVs and trucks and the high demand for those vehicles in America.  Basically, American love their trucks, so there should be better hybrid versions on the market.

The timeline for this duo's drivetrain has only been limited to we like it herbal viagra sometime later this decade, but the pair will each use the drivetrain in their own vehicles, not in any collaborative vehicles.  Seeing as SUV and truck hybrids have been the least efficient hybrids produced so far, the sector needs some great improvements, so it's good to see automakers working together toward this goal.

Boston Getting 150 Coulomb ChargePoint Stations
Written by Megan Treacy on 23/08/11   

Boston is getting a nice large EV charging network via Coulomb Technologies' ChargePoint stations.  The more than 150 chargers will mainly be located within the Route 495 Beltway.

The news was part of a joint statement released by Coulomb and how much cialis BMW, whose Active E all-electric vehicle, i3 and i8 are all on the way in the next couple years.  The automaker was assuring Boston drivers that they'd have plenty of mexico viagra no prescription places to recharge by the time the plug-in vehicles launch.

Solar Roadways Set to Build First Solar Parking Lot
Written by Megan Treacy on 19/08/11   

Solar Roadways, the company behind a technology that could transform the nation's roads into a network of shatter-proof, energy-generating solar panels, has just a received a new $750,000 grant from the federal government.  With that money, the team will get to work at developing a prototype solar parking lot that will fully put their technology to the test.

The federal government has previously given the start-up a $100,000 grant and they also received $50,000 from GE's Ecomagination Challenge that allowed the company to fully develop its 12 foot x 12 foot solar panel.  The panels contain LED lights that could display road warnings and directions, while embedded heating elements could also help keep snow and ice from gathering on roads.  Underground wires will connect the panels to the grid to power street lights and even nearby buildings.

This fantastic idea has only one real drawback -- each panel costs about $7,000, which when spread across a network of roads and parking lots would add up quickly.  Hopefully as Solar Roadways continues to test and develop its technology, cost-saving measures can also be found.

Wind Farms Off the Coast of Rhode Island Could Generate 1,000 GW of Electricity
Written by Megan Treacy on 18/08/11   

Secretary Ken Salazar made an appearance in Rhode Island today to announce that the Federal government was accepting applications for offshore wind farm projects off the coast of the state and only now where can i purchase viagra that it would start signing offshore leases for those projects by 2012.

Rhode Island is getting special attention because of the huge potential for offshore wind in the state.  Salazar pointed to an NREL study that found that Rhode Island offshore wind farms could potentially generate 1,000 gigawatts of electricity -- enough to power most of the U.S.

The state has already announced plans for a couple of offshore projects:  one is a smaller wind farm that will power the currently diesel-generator-dependent Block Island and feed any excess power to the mainland and the other is the viagra pfizer online huge 1,000 MW Deepwater Wind Energy Center that will be located in the Rhode Island Sound with transmission lines running from Massachusetts to click now how much is viagra New York.

With the government pledging to start signing offshore leases and the wealth of puchase propecia online electricity that could be generated, there will likely be more cropping up soon.

Wal-Mart Going 100% Renewable in Canada
Written by Megan Treacy on 17/08/11   

Wal-Mart Canada has revealed that they're working towards getting 100 percent of their electricity from renewable energy.

To meet that goal, two large Canadian stores have been outfitted with rooftop solar panels and wind turbines, with other major projects on the way.  The retail store intends to generate enough renewable energy to sell some back to the grid.

Hopefully, these plans extend to the U.S. as well.  Many stores here have been outfitted with solar panels, and a New Jersey store will soon replace all its light poles with wind turbines, but the company has indicated that they'll only work towards being completely powered by renewable energy if that renewable energy matches or beats grid parity.  So, as long as it's cheap.

Iowa Now Gets 20% of Its Electricity from Wind
Written by Megan Treacy on 15/08/11   

Iowa has hit a pretty big milestone in wind energy generation -- the state now gets 20 percent of its electricity from wind power.  That's the highest percentage for any state in the U.S. and about on par with wind heavy nations like Denmark.

The American Wind Energy Association (AWEA) reported that the state hit the mark in the second quarter of the year after a new 594 MW wind farm came online outside of Adair.  The even better news is we recommend cialis online that Des Moines utility company MidAmerican Energy has two more big projects like it on the way in 2011.

With 4,000 MW, Iowa is second in total installed wind power capacity after Texas, which has 9,000 MW.  The Lone Star state's much larger population means that capacity doesn't stack up the cialis arterial fibrillation same percentage-wise though.

The great lesson from this is that if Iowa can get to 20 percent wind power, any state can, and it looks like we're moving in that direction.  The AWEA reported that as of the beginning of July, 7,354 MW of new wind power was under construction in the U.S.
