Small Hydrogen City Car Will be Open Source

A new concept for a hydrogen city car is being unveiled next week in England, and you can help to finish the design. The car has been designed up to this point by Oxford and viagra india pharmacy Cranfield University professors and students, but now Riversimple is planning to where can i purchase viagra online manufacture the car and they're leaving the project open source, making the design available online.

The car will be about the same size as the smart fortwo, weigh 770 pounds, reach speeds of 50 mph and have a range of buy ultram online with mastercard at least 200 miles. The hydrogen fuel cell will only be 6kW and there will be electric motors in each wheel. A bank of ultracapacitors will take the place of a battery.

Another interesting part of the concept is viagra discount prices that Riversimple plans to lease the car for a period of 20 years, with the cost including the price of fuel. While we love the idea of the same car being used for 20 years, it's hard to imagine that many consumers would want to commit to that long of a lease. But the idea of the price including fuel may be a great idea.

The company is working on ten prototypes at the moment, but hopes to pair up with a city in the near future to launch the car and the very good site levitra en gel necessary hydrogen infrastructure at the same time.

Hydrogen Fuel Cell Tractor

When we talk about hydrogen fuel cell technology, we tend to info viagra talk about it's application in cars, but one company thinks it might work just as well in farm machinery. New Holland just revealed the NH2, a powerful tractor in every way exept it runs on a hydrogen fuel cell instead of gasoline.

The first to be introduced for commercial production by any tractor-maker, the NH2 has no gearbox or clutch, just like an electric car and the fuel cell generates 106 horsepower. New Holland hopes to have the NH2 ready to be sent out for testing within two years and a production model ready by 2013. Currently, one hydrogen tank only offers 1.5 - 2 hours worth of running time for the tractor, so the company will work on improving the efficiency before it goes to production.

While farm machinery is already expensive, the NH2 will likely be even more so because of the high cost of fuel cells, but it's great to see emission-free technology moving beyond just automobiles and into an industry associated with such great greenhouse-gas emissions like farming. The more companies and industries we have focusing on only best offers buying levitra in the us developing the technologies, the quicker we will have more efficient and ordering levitra online cheaper forms of them in all facets of life, all around the tramadol online fedex shipping $117.00 globe.

Cheap Hydrogen from a Stainless Steel Brush

Microbial electrolysis cells (MECs) have been developed over the last few years as a way to produce hydrogen from food scraps and waste water. To put it very simply, the microbes feed on the waste and with the help of we recommend viagra pills canadian electricity and a catalyst, hydrogen is made. So far, expensive platinum has been used as the catalyst in this process, which has been effective, but the cost has held the technology back. Now researchers at Penn State have found a cheap substitute: stainless steel.

A piece of stainless steel works as a catalyst, but is only one-third as effective as the platinum, but researchers found that arranging the stainless steel in the form of a high-density bristle brush upped the hydrogen production to match and even exceed that of the platinum. The best part is that while the 100mg tablets of viagra platinum part costs 15 cents, the stainless steel brush only costs 3 cents.

The researchers are still experimenting to find the best types and arrangements of stainless steel to maximize the hydrogen production, and even once those things are figured out, scientists will still have to discover a way to scale up this technology to be commercially viable. It seems daunting, but decreasing the cost will go a long way in allowing further progress.

Carbon Nanotubes Lower Cost of Fuel Cells

One of the more expensive parts of buy cheap generic levitra a standard fuel cell is its platinum catalyst. Platinum is a metal that is good at splitting up the oxygen (O2) molecule into two oxygen ions (O+) at the cell’s cathode. Platinum is also pretty expensive. In a fuel cell for a typical passenger car, the platinum catalyst can cost about $4,000.

Researchers at the University of Dayton, however, have been able to use an array of carbon nanotubes to perform the same catalytic activity. The carbon nanotubes are doped with nitrogen (the full name is nitrogen-containing carbon nanotubes, or VA-NCNTs) – this is to prevent the carbon from reacting with oxygen to generic levitra cheap form CO, a process called “poisoning”. The CO builds up on the surface, and reduces the look here female cialis effectiveness of the catalyst over time. But these VA-NCNTs keep carbon unreactive, and thereby prolong the catalyst’s lifetime.

There’s no estimate yet on how much such a fuel cell would cost – no one has built a full prototype. There will certainly be costs involved in processing such precise and aligned nanotubes, but such costs would also certainly go down with economies of scale. The bottom line is that carbon is plentiful and cheap, while platinum is rare and expensive.

As fuel cells can be designed with fewer and fewer such rare metals and materials, the concept of a hydrogen economy gains more long-term credibility. Sure, some claim that hydrogen technology will always be 10 years away. But that statement is more a reflection of the practical hurdles that stand between us and a hydrogen economy, and less a reflection of technical flaws in the plan. That is, the hydrogen economy still looks really good on paper, and the replacement of generic cialis shipping platinum catalysts with carbon makes it look even better.

New Hydrogen Tank 60% Lighter Than Battery Pack

A Dutch-sponsored researcher has discovered that an alloy of magnesium, titanium and nickel could get us closer to more efficient and safe hydrogen cars. The alloy is great at absorbing hydrogen and a tank of the material could be up to 60% lighter than a battery pack that covers the same distance.

Current hydrogen storage tanks that have proven secure are very heavy and generic viagra compare have so far limited the amount of hydrogen that could be stored in a vehicle, which limits its possible distance per tank. Robin Gremaud, the researcher responsible for this discovery, compared the weight necessary for a 400 kilometer trip using batteries and this new alloy tank. The trip required 317 kilograms of lithium batteries and 200 kilograms for the hydrogen tank.

While still not as light as researchers are trying for, it's still a great improvement and shows that advances are being made.
