Dishwasher-Size, 25kW Fuel Cell In Development

mcgrew writes “Forbes has an article about a new type of fuel cell that is 90% less costly than current cells at one tenth the size (making it the size of a dishwasher), with far higher efficiency than current cells. It runs at only 149 degrees Celsius (300F) . It was jointly developed by Diverse Energy and the University of Maryland. ‘The first-generation Cube runs off natural gas, but it can generate power from a variety of fuel sources, including propane, gasoline, biofuel and hydrogen. The system is a highly efficient, clean technology, emitting negligible pollutants and much less carbon dioxide than conventional energy sources. It uses fuel far more efficiently than an internal combustion engine, and can run at an 80 percent efficiency when used to provide both heat and power.’ It produces enough power to run a moderate-sized grocery store, or five homes. A smaller, home-sized unit is on the way. Is the municipal power plant on the way out?” Read more of this story at Slashdot.

Did you know that the Saturn V’s fuel economy was 7 inches per gallon?

An incredible fact from a fascinating new Buzz Aldrin interview: the Saturn V was only making 7 inches to the gallon at the moment of launch. Of course, the fuel economy improves dramatically when you actually take into consideration the entire distance travelled. Read more…

Tiny Ion Engine Runs On Water

symbolset writes “Discovery News is covering a project by two engineers from the University of Michigan to pair cubesats with tiny ion engines for inexpensive interplanetary exploration. The tiny plasma drive called the CubeSat Ambipolar Thruster (CAT) will ionize water and use it as propellant with power provided by solar cells. In addition to scaling down the size of ion engines they hope to bring down the whole cost of development and launch to under $200, 000.” Read more of this story at Slashdot.

Nuclear Rocket Petition On White House Website

RocketAcademy writes “A petition on the White House website is calling for the United States to rapidly develop a nuclear thermal rocket engine. Nuclear rockets are a promising technology, but unless NASA develops a deep-space exploration ship such as Johnson Space Center’s Nautilus X, a nuclear rocket would be wasted. Launching nuclear rockets may pose regulatory and political problems as well. Practical applications may depend on mining uranium or thorium on the Moon.” Read more of this story at Slashdot.

The New Ethanol Blend May Damage Your Vehicle

Hugh Pickens writes writes “About 80 percent of the gasoline consumed in the U.S. is blended with ethanol, primarily with a 10 percent mix of ethanol, generally derived from corn. Now Kate Sheppard writes that the Environmental Protection Agency has approved a new policy that will allow states to raise the blend to up to 15 percent ethanol (also known as E15), approved for use for cars and light trucks from the model year 2001 and later. A few weeks ago, AAA issued a statement saying that the EPA’s new policy creates the ‘strong likelihood of consumer confusion and the potential for voided warranties and vehicle damage.’ AAA surveyed vehicle manufacturers, and found that only about 12 million of the 240 million vehicles on the roads today are built to use E15 gasoline. The EPA will require that gas pumps with E15 bear a warning sign noting the blend and that it is not recommended for cars older than the 2001 model year. But what happens if you accidentally use it? ‘Nobody really knows what negative effects [E15 is] going to have on the vehicle,’ says Brian Lyons, Toyota’s safety and quality communications manager. ‘We think that there needs to be a lot more study conducted to make sure there are no longer term effects on the vehicle. So far everything we’ve seen says there will be.’ The concern is that repeated, long-term exposure could cause the higher-alcohol-content fuel to degrade engine parts like valves and cylinder heads — which could potentially cost thousands of dollars to replace. Gas station owners don’t like it very much either, because they’d likely have to upgrade their equipment to use it. Nor are environmental groups big fans of the EPA’s decision arguing that increasing the use of ethanol can drive up food prices, and isn’t the best means of reducing our reliance on foreign fuels. The ethanol lobby is the only group that really seems to like the new rule. ‘We’ve force fed a fuel into every American’s car that benefits a few thousand corn farmers and ethanol refiners at the expense of virtually every other American,’ says Scott Faber.” Read more of this story at Slashdot.

DOE Wants 5X Improvement In Batteries In 5 Years

dcblogs writes “The U.S. Dept. of Energy has set a goal to develop battery and energy storage technologies that are five times more powerful and five times cheaper within five years. DOE is creating a new center at Argonne National Laboratory, at a cost of $120 million over five years, that’s intended to reproduce development environments that were successfully used by Bell Laboratories and World War II’s Manhattan Project. ‘When you had to deliver the goods very, very quickly, you needed to put the best scientists next to the best engineers across disciplines to get very focused,’ said U.S. Energy Secretary Stephen Chu, on Friday. The Joint Center for Energy Storage Research isn’t designed to seek incremental improvements in existing technologies. This technology hub, according to DOE’s solicitation (PDF), ‘should foster new energy storage designs that begin with a “clean sheet of paper” — overcoming current manufacturing limitations through innovation to reduce complexity and cost.’ Other research labs, universities and private companies are participating in the effort.” Read more of this story at Slashdot.

US Warships Could Soon Run on Detonated Waves

Every one of the modern US Navy’s 129 ships, and its entire fleet of aircraft, relies on gas turbines for either basic propulsion or to generate electricity for their critical systems—typically both. But as fuel costs continue to rise, these turbines now burn through nearly $2 billion of fuel annually. That’s why the Naval Research Lab is developing a revolutionary new type of engine that could reduce our armada’s energy consumption by as much as 25 percent (and save $400 million a year) even as the Navy transitions to “all electric” propulsion systems.

Sweden Imports European Garbage To Power the Nation

Hugh Pickens writes “NPR reports that Sweden’s program of generating energy from garbage is wildly successful, but recently its success has also generated a surprising issue: There is simply not enough trash. Sweden has recently begun to import about eight hundred thousand tons of trash from the rest of Europe per year to use in its power plants. Sweden already brings trash from Norway and hopes to get garbage from Italy, Romania, Bulgaria and the Baltic countries. Sweden creates energy for around 250,000 homes and powers one-fifth of the district heating system. Its incineration plants offer a look into the future where countries could potentially make money off of their trash instead of dumping. Landfilling of organic materials – a highly inefficient and environmentally degrading system (PDF) — has been forbidden in Sweden since 2005 and emissions of the greenhouse gas methane from landfills has fallen dramatically (PDF). ‘I hope that we instead will get the waste from Italy or from Romania or Bulgaria or the Baltic countries because they landfill a lot in these countries,’ says Catarina Ostlund, a senior advisor for the country’s environmental protection agency. ‘They don’t have any incineration plants or recycling plants, so they need to find a solution for their waste.'” Read more of this story at Slashdot.

Australians Urged To Spoof IP Addresses For Better Prices

angry tapir writes “Choice, a prominent Australian consumer advocacy group, has urged Australians to obfuscate their IP address to avoid geo-blocking and use US forwarding addresses to beat high IT prices. Australia is currently in the middle of parliamentary inquiry into the country’s disproportionately high prices for technology. Choice also suggested setting up US iTunes accounts and using surrogate US addresses for forwarding packages from American stores. Choice has noted previously that Australians pay 52 per cent more for digital music downloads on iTunes compared to US users.” Read more of this story at Slashdot.
