Forget Wave Power, Google and levitra 40 mg Others May Use Poo Power for Data Centers

Google has been tinkering with the idea of a floating, wave-powered data center for a while, but it looks like a better solution could come from a more basic power source:  manure.  Hewlett Packard has released a research paper that states that tech companies like themselves, Google and Microsoft could benefit from a partnership with dairy farmers, using the cattle waste for fuel.

The research paper says that the dairy farmers could rent out land and power to the canada viagra tech companies with a return on investment in waste-to-fuel systems in two years, making it a great arrangement for the farmers too.  Farmers want to build biogas plants where manure is processed and the methane produced is used in place of buy cialis from china natural gas or diesel, but the cost of equipment is often too expensive for them to finance on their own.  This is where the tech companies come in.

As companies move their larger and larger data centers into rural areas with plenty of land, teaming up with local farms seems to be a natural fit -- farmers need a way to get rid of the vast amounts of waste and tech companies need an affordable, clean source of energy.

An average cow produces enough manure to power a 100-watt light bulb and 10,000 cows could potentially power a 1-MW data center, a small computing center.  But another possible link between the farms and companies is that the biogas systems require a lot of heat to make fuel and bestellen levitra online computing equipment in data centers produce a lot of waste heat, so a loop could be created where the biogas plant powers the cheapest viagra data center and the waste heat from the data center helps power the biogas plant.

The paper sees California and Texas as being the testing grounds in the U.S. for this partnership, while China and India could also benefit from such an arrangement.

Japan Turns to Adult Diapers for Fuel

Japan's population is recommended site order prescription levitra getting older.  Their birth rate has declined, and with that, a drop in production of baby diapers.  But conversely, the production of adult diapers has risen seven percent in just two years, hitting 5 billion units last year.  Leave it to Japan to turn an increase in adult diaper waste into a great fuel making opportunity.

Enter Japanese company Super Faiths who has created their SFD Recycle System machine that automatically shreds, dries and sterilizes dirty diapers from hospitals and nursing homes, and turns them into fuel pellets.  These bacteria-free pellets can then be used in biomass boilers and stoves for home or water heating.

Unlike the buy real levitra online without prescription diaper-recycling plants that exist in Europe, these machines can be installed directly at the source.  A hospital in Tokyo has two machines that process a total of canada levitra 1,400 pounds of disposable diapers a day.  It takes a day for the diapers to become fuel material.

Super Faiths has three different sized models that can process from 330 to 1,102 pounds of diapers a day.

NASA's Robot Diver is Fueled by Ocean Temps

newest robot can dive and swim for indefinite periods of time because it's powered by an unlimited resource:  the ocean's temperatures.  The robotic buoy utilizes thermal energy each time it moves from cold deep waters to warm surface waters.

The SOLO-TREC diver has been taking 500-meter dives off the purchase of levitra coast of Hawaii collecting information on ocean salinity and currents since last November.  The robot makes three trips a day, constantly recharging itself.

The robot is outfitted with tubes of oil.  Those tubes are surrounded by a compartment filled with wax that liquifies once the robot hits warm waters.  The liquified wax expands, which squeezes the oil from the tubes into the interior of the buoy it's stored at high pressure.  The oil is then released, which drives the generator and charges the batteries.

This process produces about 1.6 Wh, which fuels the buoy's functions like water intake and expulsion, a GPS receiver, and its sensors and transmitters.

NASA plans to cialis 25mg create a whole fleet of these robot buoys that will monitor various ocean conditions.  The next step will be to develop similar devices that would never require a battery change.

World's Best Water Purifier May be the cheapest 100 viagra uk Cactus

Scientists from the University of South Florida have discovered the water purifying power of the prickly pear cactus.  An extract from the desert-dweller is very effective at removing sediment and bacteria from dirty H2O and, even better, it grows all around the world.

The scientists aren't the first to realize this plant's ability.  Nineteenth-century Mexican communities used the cactus as a water purifier. The thick gum in the cactus that stores water is responsible for the purification.  The scientists extracted the gum and then added it to water that had been dirtied up with sediment and bacteria.

The gum caused the sediment and bacteria to combine and we recommend canada levitra online settle to the bottom, filtering 98 percent of the bacteria from the water.  The next phase is to test it on natural water.

The scientists see communities in developing countries using the cactus on daily basis.  They could boil a slice of it to release the gum and then add it to water just like the scientists did.  But there are hurdles to overcome.  What resources would be necessary for widespread growth of the cactus for this purpose and how can people ensure the "treated" water is truly bacteria free?  If these problems can be solved, cheap, clean water could be accessible for millions who are currently without.

Who Knew? Whale Poo is cheap levitra canada Fertilizing the Oceans

Australian scientists have discovered that whale poo is not only helping ocean plant life to pfizer levitra uk flourish, but also increasing the ocean's ability to absorb CO2.

Because whales' diets are made up largely of iron-rich krill (small crustaceans), their droppings are a great fertilizer for marine plants, helping them to grow like weeds (or algae).  These plants then do their part by absorbing CO2 as they grow, a process that scientists have tried to amp up (unsuccessfully) in Antarctic waters with iron fertilization.

Researchers say one-third of the world's oceans are low in iron.  On the other hand, whale excrement contains a very high concentration of viagra no prescription delivered in canada the mineral -- about 10 million times the concentration in Antarctic seawater.  But how will scientists use this information?  That's not clear yet, but it's a great reminder of how intricately well-tuned nature can be.
