KAIST Bus Charges Itself En Route
Written by Sarah Rich on 11/09/13   

There are many solutions, proposed or in development, to address the “range anxiety” EVs produce, from implementing fuel cells to self-propelled trailers. The Korea Advanced Institute of Science and Technology (KAIST) has developed another solution to tackle the problem. The system, called OLEV (online electric vehicle), lets vehicles charge themselves while on the road or even when stationary.

Last month, two self-charging buses outfitted with OLEV took to the road in Gumi, a city in central South Korea, carrying commuters along a 15-mile roundtrip route. These buses are equipped with lithium-ion batteries, charged by electric cables under the road. These cables create a magnetic field, which a receiving device under the OLEV converts into electricity, wirelessly charging the http://sws-bl.com/generic-levitra-next-day-delivery batteries on board.

While range anxiety is a major challenge for the EV industry at large, unfortunately this solution isn’t one that’s easily transferred to all EVs--unless many, many more roads were equipped with the technology, too--and overhead cables still remain easier to install. Nevertheless, this system application already has plans to expand, with 10 more buses set to hit the road in Gumi by 2015.

The Solar-Powered Hyperloop
Written by Sarah Rich on 09/09/13   

With airplanes ranking among the biggest gas guzzlers in the transportation industry, Elon Musk’s Hyperloop sounds like a potential replacement for such energy inefficient travel--at least between places 1,000 miles apart. Instead of boarding commercial airplanes, people could travel via aluminum pods, whizzing through elevated steel tubes toward cities typically congested on the ground below. If the Hyperloop could be produced as designed, it’d be completely solar-powered and reach past the average speed of an airplane at 800 miles per hour.

Even at this design stage of the canadian legal cialis Hyperloop there are many valid critiques to consider. For example, at such high speeds, the friction would make figuring out cooling methods that wouldn’t impede the pods themselves essential, and the g-forces, double that of where to buy viagra pills typical roller coasters, could make for an uncomfortable ride. Musk states that disappointment with California’s new “high-speed” rail sparked this idea, but it doesn’t seem like it’ll move beyond the idea stage soon.

As HuffPo reports, since Tesla and SpaceX are so demanding, Musk claims he will likely not make the Hyperloop himself. Although there are advantages to the current lack of Hyperloop production: as it stands, anyone can offer suggestions to improve the system, as the last page of the plans lists two emails where readers can send feedback. Still, with so much remaining to be sussed out--from safety issues to the legal concerns surrounding construction--it seems we’re a long way away from seeing a prototype in action.

First Container Ship Crossing the Northern Passage
Written by Philip Proefrock on 04/09/13   

For the past few years, the Arctic has been sufficiently ice-free in the summertime that some ships have been able to take the short-cut routes across the North Sea Route and the Northwest Passage. Last year, among others, a small sailboat with a crew of 3 made the Northwest Passage. This year, a 19,000 ton Chinese cargo container carrier is traveling to Amsterdam via the viagra without prescription sales Arctic, going north and traveling along the northern coast of Russia, rather than down through the Indian Ocean and through the Suez Canal and cialis online no prescription the Mediterranean. This marks the first time that a container ship is traveling through the Arctic.

The shorter trip will mean lower fuel costs (and, ironically, fewer greenhouse gas emissions) for the freighter. Taking this route is expected to save 12 to 15 days of travel and shortens the trip by roughly 7,000 kilometers (4,350 miles).

While this is news now, it is all too likely that this will go from a unique occurrence to an ordinary annual event within a few years.

Ecuador Ends Novel Plan to Save Rainforest
Written by Philip Proefrock on 03/09/13   

After several years of trying to protect one of www.celebratinglife.org the most undeveloped parts of the Amazonian rainforest, Ecuador has ended an attempt to get the rest of the world to contribute money to offset that nation's need to exploit the region for its oil wealth. The Yasuni National Park is an incredibly biodiverse, undeveloped region in eastern Ecuador, on the border of Peru. The park comprises an area of 9,820 square kilometers (3,792 sq. miles) in the headwaters of the Amazon. There are also an estimated 800 million barrels of crude oil in the region.

As with conservation land trusts, and carbon offsets, and similar kinds of click here generic cialis sale preservation efforts, the government of Ecuador sought payment equal to half of the oil's commercial value ($3.6 billion in 2007) in exchange for leaving it untouched and remaining in the ground. Not only would that prevent the roguelephant.com damage that development of the region for oil production would cause, but it would also help to sequester that volume of oil from eventually adding to the growing amount of atmospheric carbon dioxide.

To date, there has been little support for this initiative. Only a tiny portion ($6.5 million) of the money that Ecuador sought has been offered, so President Rafael Correa has now announced an end to the program:

President Correa said scrapping the program was one of the hardest decisions of his presidency. "The real dilemma is this," he said in a televised address last week. "Do we protect 100 percent of where can i purchase cialis the Yasuní and have no resources to meet the urgent needs of our people, or do we save 99 percent of it and have $18 billion to fight poverty?"

While the premise seemed to make good sense from a global perspective, its timing couldn't have been worse; the proposal was begun in 2007, just as the financial crises triggering the Great Recession were flaring up. This shouldn't necessarily be read as a failure of the approach in general, but rather a first, grand-scale attempt that didn't work out. Hopefully there will be future attempts like this, and they will have better results.

Are Cities More Sustainable Than Suburbia?
Written by Sarah Rich on 30/08/13   

Is living in the city inherently greener than living in the suburbs? Researchers like Edward Glaeser have argued a resounding yes: “In almost every metropolitan area, carbon emissions are significantly lower for people who live in central cities than for people who live in suburbs.” This conclusion has common sense on its side. Despite the literal greenness of many suburbs, high density living would seem to reduce energy use by default: less car and fossil fuel dependency, more infrastructure efficiency, with the largest cities generating the i recommend best way to use levitra biggest energy-saving boost.

But new research from Canada’s Dalhousie University contests the claim that cities are immensely greener than their suburbs and adds additional information to consider when comparing population density and emissions. Researcher Jeffrey Wilson and discount generic levitra his team looked at greenhouse gas emissions around Halifax, Nova Scotia, and found a negligible difference between suburban and city pollution: only a 0.3kgCO2e/person/day difference. While suburbanites did drive more, those in the city produced more home-energy emissions per household member than their suburban counterparts, bringing their total emissions closer to each other. Exurbs dwellers, however, needing to travel the furthest, polluted the most. Those in the exurbs produced 11 percent more emissions than those living in the inner city.

This research does broaden the conversation, illustrating that not all cities necessarily have a significant environmental edge over their suburbs. As Eric Jaffe at The Atlantic Cities points out, however, the study has a few problems: it doesn’t account for income level (the wealthier exurb dwellers may emit more greenhouse gases in part because they have more disposable income), and doesn’t compare the data by season--only across a year. Additionally, while Halifax Regional Municipality’s suburbanites and urbanites might be similar in greenhouse gas emissions, its hard to know how much this can speak to other regions’ internal relationships when other studies have looked at more metropolitan areas.

Solar Drone Aircraft Work As Atmospheric Satellites
Written by Philip Proefrock on 23/08/13   

Part of the resurgence of airships in recent years has been due to research carried out with an eye toward long-duration purposes such as surveillance, imaging, and even serving as regional wireless antennas. But developments in unmanned aerial vehicles and military drones, as well as improvements in solar powered aircraft are being combined into smaller, unmanned, conventional aircraft. The advantage of high-altitude and long-term persistence that was once the sole province of best rx tramadol satellites is now becoming more readily available as winged drones seem poised to leap past airships.

One example is the cialis paypal Titan Aerospace Solara 50, which has the potential to carry up to 70 pounds (31.75 kilograms) of payload and stay aloft at an altitude of 60,000 to 70,000 feet (18.3 to 21.3 kilometers) and remain there for years. Of course, in the current security-focused environment, the initial targets for these drones will most likely be military and no prescription saturday delivery tramadol policing applications with their enormous budgets. But, as the technology is developed and becomes available, scientific and civilian commercial uses for these drones will come into play.

"The Solara 50 has a 50 m (164 feet) wingspan. The upper surfaces of its wings and tail are packed with over 3,000 photovoltaic cells capable of generating up to 7 kilowatts." Titan is also developing a larger model, the Solara 60, which will be able to carry a larger payload of up to 250 pounds (113.4 kilograms). Furthermore, the Solara 60 could also provide 100 watts to the payload, enabling quite a range of equipment to be powered on board the craft.

Tesla S Gets Highest Ever Safety Rating
Written by Philip Proefrock on 22/08/13   

Electric vehicle manufacturer Tesla Motors is justifiably proud of their Model S sedan which has scored the highest ever rating. Although the official scoring does not go past 5-star, the Model S turned in an effective rating of www.diabetes.org.br 5.4 stars.

Much of the credit for these high ratings goes to the fact that an electric motor is much smaller than an internal combustion engine. Because there is less space taken up by an engine, there is more body space that can help absorb energy in a collision. And, there is also less concern about keeping an internal combustion engine from being forced into the passenger compartment.

On the rollover test, "the Model S refused to turn over via the normal methods and special means were needed to induce the car to roll." This was because of its low center-of-gravity which comes from the where can i buy real viagra location of the battery pack, which is largely under the floor.

Synergistic benefits such as this will help further ensure that electric vehicles don't become relegated to a single-issue curiosity, but that they represent real improvements in transportation.

​White House Gets Solar Panels (Again)
Written by Philip Proefrock on 21/08/13   

The White House is being outfitted with photovoltaic (PV) solar panels this week to once again make the residence of the President of the United States capable of producing some of the energy it consumes.

The White House has had solar panels before. The first solar panels on the White House were solar hot water panels that were installed in 1979, during Jimmy Carter's presidency. Those panels were subsequently ordered removed by Ronald Reagan. Some solar panels, both PV and water heating, were again installed on the grounds of low priced prescription viagra the White House during the George W Bush administration, providing electricity for the entire White House complex, as well as water heating for the White House pool.

The new panels being installed this week are, once more, directly on the White House itself. The manufacturer and exact number of the panels has not been identified, although they are reported to be from an American company. The White House PV panels are expected to generate 19,700 kWh annually.

Fukushima Site Leaking Radioactive Wastewater
Written by Philip Proefrock on 20/08/13   

Radioactive water has been found leaking from storage tanks at the site of the Fukushima reactors which melted down in the wake of the 2011 tsunami. Three of the eight reactors at the site melted down after cooling systems failed due to damage caused by the tsunami.

Storage tanks have been built near the crippled reactors to store the great quantities of water being used to cool off the damaged reactor cores. The melted reactors will need to be cooled off for years before further decontamination work can take place.

The leak has been classified as a low-level (Level 1) incident, but still, the radioactivity of the leak has been characterized as "equivalent to the limit for accumulated exposure over five years for nuclear workers."

In India, Cost of Wind Power Competes with New Coal
Written by Sarah Rich on 05/08/13   

According to a recent report by HSBC Global Research, wind power has become cost competitive with new coal capacity in India. Solar is not far behind; the report also claims it is likely to become cost competitive between 2016 and 2018.

While policies like the wow look it order cialis reinstatement of the Generation Based Incentive for wind power projects have made them more financially viable, as HSBC reports, this specific change in the relationship between wind power and european viagra coal-based power can be partially attributed to water shortages. In India, thermal power plants account for almost 90 percent of industrial water demand. Coal-fired power plants use significantly more water than renewables like wind and solar, and water shortages have been affecting coal-based power production in India during the past three years, causing some power plants to close partially during the pre-monsoon season.

India already ranked number five for global wind power capacity as of 2011. While improvements to the power grid infrastructure would be necessary to get new wind power generation sources linked to businesses and homes, this change in relative cost likely coincides with, and perhaps will directly cause, an increase of wind power projects in India. As the HSBC report states, “India currently has 1.2GW of installed solar capacity and over 4GW of capacity is at various stages of tariff bidding. We expect commissioning of selected projects within two years.”

Rubbee TurnsRegular Bicycles into Electric Vehicles
Written by Sarah Rich on 25/07/13   

Joining other developments in electric bike technology, a compact electric drive called Rubbee electrifies most regular bicycles in less than a minute. Cyclists looking for the occasional extra boost on the road can clamp the electric drive just below the seat (fitting tubes ranging from 22-35 mm), where its polyurethane cast friction wheel meets the bike’s back tire. A throttle, installed on the handlebars, stays on the bike with or without the drive. Pedaling is optional once Rubbee is switched on; its wheel turns the back tire, allowing the cyclist to travel for 15 miles and reach a top speed of 15 miles per hour without needing to pedal.

Its integrated battery pack ensures easy travel on level terrain or at an incline, and can be charged every day for 5 years without loosing range. Its integrated suppression system, enabled by a removable fixation pin, keeps a constant force on the tire. Rubbee can stay on the bike without touching the generic viagra real back tire with the pin put in place, useful for when Rubbee’s out of juice or when a cyclist would rather travel by pedal power alone.

The London-based company, currently seeking funds via Kickstarter, states that Rubbee gets its name for the way the friction wheel rubs the bicycle tire without significant wear. It weighs 14 lbs, which could take some getting used to for those keeping Rubbee installed while it's turned off, but only takes 2 hours to fully recharge, and includes an LED tail light for more visible travel at night. While it costs £699 (roughly $1073), for those who can afford it, a drive like this would give cyclists some help up those hills.
