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 http://www.spotfodo.com/cialis-online-in-usa 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 follow link mexico levitra 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 viagra where to buy 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 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 nassmc.org 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.

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

According to viagra overnight delivery 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 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 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 viagra soft tabs tariff bidding. We expect commissioning of selected projects within two years.”

VW Announces Production of Two Electric Cars
Written by Sarah Rich on 20/09/13   

Following up on expectations, Volkswagen announced the viagra generic canada production of two new electric vehicles last week. The 2015 e-up! (exclamation mark included) and the 2015 e-Golf were unveiled at the Frankfurt Motor Show. While both hatchback vehicles contain lithium-ion batteries and electric motors, they have different specs. The smaller of the two, the e-up! runs on a 18.7-kWh lithium-ion battery and contains a 60 kW / 82 PS electric motor capable of 210 Nm of torque. The e-up! has a driving range of up to operacijatrijumf.net 99 miles (159 km), and uses a mere 11.7 kWh per 61 miles.

One of our writers test drove a pilot vehicle of the other EV announced for production: an all-electric version of the Golf. The e-Golf has a 24.2 kWh lithium-ion battery, and a 85 kW/ 115 PS electric motor with a max torque of 270 Nm. It also has a driving range of up to 118 miles (190 km), and uses 12.7 kWh of energy per 62 miles. While the e-Golf will appear in the U.S. market, production numbers have not yet been released and it is unknown whether the e-up! will follow. In addition to announcing production of these new cars, Volkswagen claims that, by 2018, it wants to produce the most electric vehicles worldwide.

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 http://cambridgeacademyaz.com/levitra-soft-generic 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 cialis soft tabs scam the leak has been characterized as "equivalent to the limit for accumulated exposure over five years for nuclear workers."

Recycling CDs for Wastewater Treatment
Written by Philip Proefrock on 30/09/13   

Someone has finally come up with an upcycling use for old CD discs. Din Ping Tsai, a physicist at National Taiwan University, has developed a small, low-power method for treating wastewater using UV light and www.markwellgroup.com.au zinc oxide applied to the CDs. Using old CDs as a substrate to coat with zinc oxide provides a low cost layer which can be spun as water is applied, creating a thin film of water which more effectively interacts with the photocatalytic layer of zinc oxide nanorods. In tests, the device was able to break down over 95% of the contaminants after an hour of treatment.

Though this could be a wonderful application for old CDs, it's unlikely to solve the waste accumulation from billions of old CDs. The number used for this treatment system, even if it becomes widely adopted, is going to be a tiny fraction of the total production of CDs (which, at present is about 20 billion CDs per year).

"The spinning disk reactor is small, consumes little power, and processes contaminated water more efficiently than other photocatalytic wastewater treatment methods, Tsai says. The device could be used on a small scale to clean water contaminated with domestic sewage, urban run-off, industrial effluents, and farm waste. Going forward, the team is also working on wow it's great gay levitra ways to superactive cialis no presecription increase the efficiency of the reactor, and Tsai estimates that the system could soon be improved to work even faster, perhaps by creating layers of http://www.richcongress.com/viagra-soft-gel stacked disks."

While the system seems best suited to small installations, rather than big, municipal facilities, it is nevertheless an interesting system, and the ability to also deal with an e-waste issue at the same time as creating equipment for effective wastewater treatemt is cialis discount a positive synergy.
