In May 2012, Mistubishi unveiled a completely unexpected version of the i-MiEV electric jellybean to challenge the climb up Pikes Peak, the MiEV Evolution. In 2013, the company unleashed the MiEV Evolution II. For 2014, well, you can probably guess.

Say hello to the MiEV Evolution III. The latest, ahem, evolution of these cars features redesigned chassis and bodywork as well as a 50 kW boost to the electric motors, up to 450 kW, which translates to a 67 horsepower increase up to 603 hp. Two of these bad boys will tackle the 2014 Pikes Peak International Hill Climb (PPIHC) later this month in the Electric Modified Division at the hands of drivers Greg Tracy and Hiroshi Masuoka. The race starts at 9,390 feet and ends at 14,110 feet above sea level and takes place June 29.

Mitsubishi hasn’t yet managed to win the EV category in. The first Evolution crashed during practice and last year Masuoka came in second in the EV division while Tracy came in third. The 2013 winner was Nobuhiro “Monster” Tajima in the Monster Sport E-Runner. Will the third time be the charm?

Stunning Baatara Gorge Waterfall September 18, 2014

Filed under: Uncategorized — bferrari @ 8:29 am

The Baatara Gorge Waterfall (or the Baatara Pothole Waterfall) is located in the village of Balaa, between the cities of Laqlouq and Tannourine, Lebanon. The location is also known as the “Three Bridges Chasm” (in French “Gouffre des Trois Ponts”).

This unexpected waterfall drops 255 metres (837 ft.) into a cave and falls behind three natural bridges, which raise one above the other and overhang the chasm descending into Mount Lebanon. It can only be seen during the months of March and April, when the snows are melting.

 SeaOrbiter can carry a mix of scientists and crew members.

SeaOrbiter can carry a mix of scientists and crew members.

A French architect’s audacious plans for a ship that will change the ocean exploration is done.

Garnering comparisons to Star Trek’s starship Enterprise, the SeaOrbiter is the brainchild of French architect Jacques Rougerie. Set to begin construction this spring, the 190-foot-tall semisubmersible vessel will be the culmination of nearly 30 years of Rougerie’s research and development.

Six of the SeaOrbiter’s 12 floors are below sea level, allowing for uninterrupted underwater observation. Although the ship’s main mission is to research the biodiversity and climate of the sea, the real goal for Rougerie is to give the public a better understanding of how crucial the ocean is to Earth’s well-being.

Ninety-nine percent of the $50 million project was financed through the French government and private companies. To get people more involved, Rougerie is crowdfundingthe last 1 percent of the project. “The more humans understand about the underwater world, the more respect they will have for it,” he says.

22 People: Number the SeaOrbiter can host. The ship will carry a mix of scientists and crew members.

Quite a View: ‘We want people to appropriate the project to themselves,” says Rougerie. Which is why he raised money through KissKissBankBank, a French crowdsourcing website, to fund construction of the Eye of the SeaOrbiter. Equivalent to a ship’s crow’s nest, the Eye towers 60 feet above the surface. It serves as a lookout and houses a communications system that lets the crew send live broadcasts of life on board.

Hard at Work: Keeping busy won’t be a problem for the crew. The “modular lab” can be used as a laboratory for scientists as well as a fitness room equipped with treadmills. The lab also includes a medical zone. A certified doctor with basic surgery skills will be on board in the event of an emergency.

2,600 Tons Displacement: The overall weight of the ship. It is built from 500 tons of Sealium, a recyclable aluminum designed for marine environments.

A Life Aquatic: Given that voyages will last three to six months, there will be ample time to collect data and perform experiments. The underwater area, known as the hyperbaric lab, is equipped with an observation deck made of transparent polycarbonate panels, allowing for direct underwater observation. Because the conditions underwater are similar to those in space in terms of pressure and isolation, the SeaOrbiter will be used by NASA and ESA (the European equivalent) for protocol training as well as physiological and psychological experiments.

Go With the Flow: The SeaOrbiter was designed primarily to float along with the ocean’s natural currents, allowing scientists to study the relationship between those currents and climate. The keel weighs 180 tons and helps provide stability to the ship. It can be retracted when the vessel is in shallow water.

5 Ships: The total number of SeaOrbiters Rougerie eventually hopes to build, one to sail in each of Earth’s oceans. A number of partners have given their support to the SeaOrbiter project, including National Geographic and UNESCO.

 

Laser-sparked fusion power passes key milestone July 9, 2014

Filed under: Energy Exploration,Energy Generators,Green Living — bferrari @ 7:50 am

The dream of a completely clean, high powered and almost limitless renewable energy source is getting closer. Nuclear Fusion is the process by which atoms
are compressed to such a degree that their nuclei fuse, releasing a huge amount of energy. Essentially it is the opposite of current Nuclear Power, based on fission whereby large nuclei are torn apart to release energy. This is the process which happens in stars, turning Hydrogen into the heavier Helium, and all other natural elements.

The National Ignition Facility in California began experimenting in 2009 to slow progress. They are using lasers and X-rays to compress a fuel pellet with a frozen Hydrogen Istotope, but it takes significantly more energy to start the fusion reaction than the process actually produced, making it currently ineffective as a fuel source.

However, an article in Nature this week confirmed that a milestone had been passed, whereby of the amount of energy actually delivered to the pellet, the reaction released a surplus of energy. The next step is to improve the efficiency of how the lasers deliver energy to the pellet. However, this is still a long way away, perhaps decades, but once that has been refined, mankind will essentially be able to build miniature stars to produce nearly unlimited energy.

Coming soon to a kitchen near you—magnets in your refrigerator. And we’re not talking about slapping your kid’s artwork inside the fridge next to the milk and butter.

It’s the next generation of residential food and drink cooling, and it’s powered by magnets. Gone will be the almost century-old unit in your kitchen that uses a heat-transfer process based on liquid refrigerants called vapor compression refrigeration. Condensers and refrigerants will be replaced with magnets and special alloys that get hot and cold based on their proximity to magnetic fields. The technology could also be used for air-conditioning.

Magnetic refrigeration, proponents say, is a rapidly approaching technology that will amount to a revolution in domestic energy use.

“It’s the equivalent to a gas-powered car moving to electric—that’s the kind of leap we’re making in refrigeration,” said Ed Vineyard, a senior researcher at the U.S. Department of Energy’s Oak Ridge National Laboratory. Vineyard’s Building Technologies Programhas teamed up with GE to bring magnetic refrigeration to the public in around five years.

The idea behind refrigerators and air conditioners is all the same. In their broadest sense, they are heat pumps—devices that take heat energy from inside your refrigerator box or room and move it outside. Removing this energy makes the temperature go down.

In most contemporary home and commercial refrigeration systems, mechanical work compresses and expands a liquid refrigerant. The pressure drop associated with expansion lowers the temperature of the refrigerant, which then cools air blown over it by a fan into the refrigerator box or the cooled room. In magnetic refrigeration systems, the compressor is replaced with magnetic fields that interact with solid refrigerants and the water-based cooling fluid. Changing the strength of magnetic fields alters how much heat is pulled away from the refrigerator box.

Along with this refrigerator revolution comes a dramatic drop in the amount of energy you need to cool your cucumbers and cantaloupes. ORNL says magnetic refrigeration “is a promising alternative to the vapor compression systems used in today’s appliances” that could theoretically drop energy consumption by 25 percent compared to current technology. Those liquid refrigerant chemicals that can be damaging to the environment and hard to recycle at the end of a refrigerator’s life are also being replaced by cheaper water-based fluid.

Oak Ridge National Laboratory’s Ayyoud Momen works on the team’s “breadboard” prototype refrigerator-freezer: a flexible platform used to evaluate material compatibility and to analyze components including the magnet, generators, motor, pump, heat exchangers, plumbing and leakless rotating valve.

Developers expect the new refrigerators to cost a bit more than vapor compression models, but buyers should see savings through spending less on electricity over the long term. If the technology is adopted broadly, it could mean major electricity savings on the national scale. Besides savings from more efficient refrigerators, magnetic cooling would lower electricity use in heating, ventilation and air-conditioning equipment, which accounts for around 60 percent of the average household’s energy use.

“We’ve spent the past 100 years making the current technology more efficient, but most of the major efficiency increases have been achieved,” Venkat Venkatakrishnan, director of advanced technologies for GE Appliances, said in a company statement. “We figured out how to create heat or cold without a compressor or chemical refrigerants. This breakthrough can power your fridge with greater efficiency, and because the technology does not contain traditional refrigerants, recycling refrigerators at end of life will be easier and less costly.”

Safe Nuclear Reactor Runs on Spent Fuel June 20, 2014

ALTERNATIVE POWER SOURCES

Molten salt is the key to this reactor's safety.

Molten salt is the key to this reactor’s safety.

It’s pretty straightforward to get some coders together in a spare room to create a software start-up. Should a nascent company have hardware inclinations, it might set out to make a consumer electronics gadget with an assist from Kickstarter. And then there’s Transatomic Power Corp., of Cambridge, Mass., which is trying to build a nuclear reactor.

Cofounders Leslie Dewan and Mark Massie began dreaming up the idea in 2010, while working on their Ph.D.s in nuclear engineering at MIT. “We realized this is probably the smartest we will ever be in our lives,” Dewan remembers. So the two decided to use their knowledge to design a better reactor, one that deals with what they see as the nuclear industry’s biggest problems: waste and safety.
The Fukushima disaster reignited the nuclear power debate, but it turns out, even with its faults, nuclear power is saving lives! That’s according to a new NASA study about the effects of pollution on health.

The design they came up with is a variant on the molten salt reactors first demonstrated in the 1950s. This type of reactor uses fuel dissolved in a liquid salt at a temperature of around 650 °C instead of the solid fuel rods found in today’s conventional reactors.

Improving on the 1950s design, Dewan and Massie’s reactor could run on spent nuclear fuel, thus reducing the industry’s nuclear waste problem. What’s more, Dewan says, their reactor would be “walk-away safe,” a key selling point in a post-Fukushima world.

“If you don’t have electric power, or if you don’t have any operators on site, the reactor will just coast to a stop, and the salt will freeze solid in the course of a few hours,” she says.

Dewan and Massie incorporated the company in April 2011, but they were still essentially just two grad students with a cool idea. Then, after their presentation at a TEDx meeting in November 2011, they met Russ Wilcox, the founder and former CEO of E Ink Corp. Having sold E Ink for US $215 million in 2009, Wilcox was looking for a new project, and he had reason to be receptive to Dewan and Massie’s scheme for extra safe nuclear power: He and his family had been at Tokyo Disneyland when the Fukushima disaster began, and he had gotten a dose of Japan’s nuclear fear.

Wilcox also thought it augured well for the technology when the TEDx attendees gave the talk a standing ovation, as nuclear projects often depend on public support. Soon the three decided to go into business together.

The team has raised about $1 million so far, much of that from friends, family, and angel investors who aren’t expecting immediate returns; now they’re looking for $15 million more to fund a series of lab experiments. Wilcox says this research will quickly reveal whether the reactor will work.

“You want to start with the riskiest parts of your design and test those first,” he says, adding that he learned that lesson while at E Ink. “Don’t spend effort designing the box before you’ve built the product.”

If those experiments reveal no showstoppers, Transatomic hopes to find industrial partners to help build a 5-megawatt demonstration plant at a U.S. national lab site. And if that demonstration is convincing, Dewan and Massie’s reactor will be ready for full-scale commercialization.

But Dewan says that’s where the entrepreneurial ride will end. “We can’t become the next Westinghouse,” she says. “The goal is to demonstrate that this is a functional technology; then we would likely be subsumed by one of the industrial partners that funded us in the earlier phases.”

Where Do We Store Nuclear Waste?

According to Albert Machiels, an expert on advanced nuclear reactors at the Electric Power Research Institute, the industrial giants of the United States and the European nuclear industry are “not bullish” on advanced reactors. But the global market looks quite different, with countries such as China and India pursuing ambitious nuclear power policies.

Machiels also notes that another interesting nuclear start-up, the Bill Gates–backed TerraPower, is cooperating with international organizations in China and elsewhere to develop its technology. If these start-ups can prove out their engineering and economics, they might find willing buyers for their intellectual property on other shores.

Coca-Cola Creates Modular System To Reuse Plastic Bottles June 4, 2014

Filed under: Green Living,Recycling,Wierd — bferrari @ 12:03 pm

 

Plastic waste is a huge problem in the world today, with recycling centers struggling to figure out what to do with all the plastic bottles being thrown away every day and landfills filling up with waste that won’t degrade for hundreds, if not thousands, of years.

So what do we do with all those leftover plastic bottles? Coca-Cola has come up with a very creative way to reuse their plastic bottles- the 2ndLives cap system.

2ndLives is a set of 16 screw on sprayers, marker tips, pencil sharpeners and other useful objects that can be attached to the top of any plastic soda bottle, essentially upcycling the plastic waste and giving it new life.

So far the bottle tops are only being distributed (for free) in Vietnam, with Indonesia and Thailand to start receiving them soon, and hopefully they’ll soon make their way to the U.S. because they look like a great idea!
