Rubber Material Harvests Energy from Small Movements

A new material developed by researchers at Princeton and cialis online best Caltech is capable of harvesting energy from the simplest of movements like walking or breathing.  This new rubber chip made of PZT (lead zirconate titanate) nanoribbons could eventually power small portable electronic devices like cell phones.

The PZT is embedded in silicone rubber sheets that produce electricity when flexed or other pressure is applied.  The scientists who developed the chip see them being inserted into shoes or even within the body to continually harness power for our portable devices.

Before that freaks you out too much, the scientists envision the chips being placed next to the the best place buy cheap levitra online lungs to utilize breathing motions for powering pacemakers.  Pacemaker users wouldn't have to undergo surgery to us pharmacy viagra replace batteries since their breathing would be a constant source of energy.

The reason this particular material stands out compared to all of the other piezoelectric materials out there is that it's far more efficient.  According to the researchers, PZT can convert 80 percent of mechanical energy applied to it into electric energy, which is 100 times more efficient than quartz.  That efficiency allows it to harness such small movements like breathing and opens up a much greater range of possibilities for its use.

Printable Lithium Batteries Coming Soon

First came printable solar cells, then printable OLED lights and now ladies and gentlemen, we have printable lithium batteries.  Japanese researchers have announced they've developed a way to manufacture the batteries with mass-output, roll-to-roll printing technology.

The printed battery sheet is very thin (500 μm), flexible (allowing it to be attached to curved surfaces) and designed for use with a flexible solar battery, a combination that could be both a power generator and power storage unit.  The battery prototypes have an output voltage of 2V - 4V, but the battery capacity hasn't been revealed.  The benefit of the roll-to-roll printing is that it's highly efficient, meaning cheaper production.

Unlike other prototype technology, this cool breakthrough isn't one that we'll have to wait 10 years to levitra no rx required see in production.  The research team, who work with the Advanced Materials Innovation Center of Mie Industry and Enterprise Support Center in Japan, plans to finish studying the technology and start shopping around for commercial opportunities sometime next year.

Wind Power Could be Stored as Ice

A perfect way of storing electricity generated by wind turbines has been elusive so far.  Ideas like super-sized batteries, compressed air and 5mg propecia hydroelectric storage have all been floated.  One company though thinks the answer could be as simple as making ice.

Calmac has come up with a storage system called IceBank that uses the 100 mg levitra energy generated at off-peak night-time hours to make ice.  That stored ice is then used for cooling purposes during high-demand daytime hours.  The company claims that reducing electricity demand for cooling can cut energy costs by 20 - 40 percent.  That reduction also means fewer emissions from power plants.

This a great solution for harnessing wind power that might otherwise go to waste during night-time hours.  And it's pretty low-tech - no need for lithium or rare earth minerals - just a souped up ice maker.

New Mexico "SuperStation" Could Link Major Power Grids

A new idea for a large substation based in Clovis, New Mexico has the potential to solve one of the biggest hurdles to clean energy growth:  transmission.  The SuperStation, as its being called, would link the three largest grids - the east, west and Texas - allowing renewable energy producers to sell electricity across the country instead of cialis prescription label just within their own grid.

The basic setup of the SuperStation would be a huge substation using superconducting cables to transmit electricity.  The cables would carry 5 GW of electricity to and from the substation where it would be converted from AC from the grids to DC and then back to AC on its way back out.   The cables are chilled to 300 degrees below zero which lets them carry more electricity, more cheaply.  Tres Amigas, the company that hopes to build the project, would charge a fee for the SuperStation's use.

As more renewable energy projects are planned and built, it's infrastructure like this that will ultimately allow that clean electricity to make it into our homes.  This project is expected to encounter lots of red tape because of the heavy regulation of power transmission, and it comes with a $1 billion price tag, so, for now, we can only hope it makes it.

IBM Sponsoring 500 Mile EV Battery Project

ibmbatteryIn the last few years, electric vehicles have gone from a dream to the next logical step for vehicles. Of course, the future of EVs is still being debated, but IBM is using its cash and influence to push for an electric vehicle battery that can carry a car 500 miles without recharging.

500 miles is how much levitra a long way, longer than most gasoline engines. And while the batteries might still require a long charge at the levitra injectable end of those 500 miles (longer than a five-minute gasoline fill up) it would still be a tremendous advantage over the 100 mile range of today's EVs.

There are a few paths to getting around this range problem. One is GM's "extended range electric vehicle" idea, which puts a gasoline generator in the car to recharge the batteries when they run low. Another is Shai Agassi's "Better Place" model, which has battery swapping stations scattered around the country for when you need a quick re-charge.

The third and most obvious option is to wait for battery technology to get good enough to satisfy the demands of enter site women cialis drivers. IBM, sick of waiting, is pushing this direction hard. The project is called the "Battery 500 Project" and it focuses on advanced battery chemistries that will increase the we recommend buying real viagra without prescription "power density" of batteries. IBM's "Big Green" project last year asked for submissions for big green ideas, and the winning submission was the "Lithium Air Battery" which is what the Battery 500 Project will be focusing on.

Conceptually, lithium air batteries use lithium as the anode and oxygen as the cathode. Because oxygen would be fed into the battery from the surrounding air, the cathode would, in effect, be weightless. And because oxygen is available on demand, the only limiting factor is natual viagra how much contact the battery can make with their air. That's where IBM's expertise comes in, they want to levitra tablets for sale take their high-tech, nano-scale semiconductor manufacturing experience and buy cialis without a prescription use it to dramatically increase the surface area of the anode.

IBM is estimating that it will take two years to determine whether this technology is feasible. But even if that means it'll be five years before they hit the market, this will still be a huge breathrough for power storage technology.
