    A deep ocean current covering that has a volume of 40 Amazon Rivers was discovered by Japanese Australian researchers. The current is said to be located near the Kerguelen Plateau in the Indian Ocean, a sector of the Southern Ocean. The spot is 4,200 kilometers south-west from Perth, Australia.

    Kerguelen PlateauThe researchers described this current in a paper published online called the Nature Geoscience. According to their report, the current is more than three kilometers below the ocean’s surface. This current stands in the pathway of the Earth’s network of global current, and can strongly influence climate patterns.

    It was also reported that the current carries dense, oxygen-rich water, which provides levels of oxygen to the deep waters of Antartica. Without this supply, there could be very low levels of oxygen in the deep sea. Dr. Steve Rintoul, the co-author of Antartic Climate and Ecosystems, also explained how the ocean affects climate change.

    Apparently, the more the ocean transports and stores heat and carbon dioxide, the slower the process of climate change becomes. This particular current which was spotted in the Kerguelen Plateau, is an important part of the global network of ocean currents that are also referred to as the “overturning circulation”. They determine just how much carbon dioxide and heat the ocean can still soak up.

    Natural gas is just one of the many alternate car fuels that are already on the market, although it is not yet widely spread and many do not even know that it does exist. However, natural gas is a viable, realistic and available alternative with many advantages for both consumers and the environment.

    A car that runs on natural gas needs to be filled up with CNG, or compressed natural gas. This fuel burns cleanly and only limited emissions come from cars that use this technology. Natural gas is also plentiful, even though it is not a renewable energy source. This is also a cheap energy source and a gallon equivalent of natural gas is never more expensive than gas or diesel to purchase.

    One problem with driving natural gas powered cars is that not many gas stations sell this fuel and therefore a long drive must be well planned or done with a different car. The tank for natural gas is also larger than that of a gas or diesel powered car which means that space is taken away from the trunk.

    Volvo C30 BEV GrayAside from the planned launch of a plug-in hybrid by 2012, Volvo is eyeing to perfect an all electric vehicle. They are also studying the marketability of the project in development against possible competitors.

    Volvo is working on a car which looks like a regular C30 packed with the usual trademark safety, space, and comfort like the standard version. The big difference is that it will be powered entirely by electricity. It has no emissions plus an excellent driving range of 93 miles on one charging.

    The car manufacturer has come up with several prototypes and tested internally how the C30 EV runs in different driving conditions. The focus of the development is the integration of the electric drive system with the rest of the components of the vehicle.

    The C30 Battery-powered EV will run using lithium ion batteries charged using a regular plug at home. Full charging may take about eight hours.

    Charging anxiety of consumers present another challenge for makers of electric vehicles. After a while though, the adoption of EV technology may flow smoothly when buyers become more familiar with EVs.

    An electric vehicle buyer may have several worries when they plug their cars at home. One may be worried about power outages, circuits giving in, or someone simply disconnecting the plug and having no enough power to use the next day.

    Charging anxiety is expected since we are EV Charger Stationfacing a new technology but it is expected to die down like how people get accustomed to new gadgets, tools, or systems. Consumers are expected to have newbie questions when they initially charge their cars. Instruction manuals will be read and phone calls will be made just to make sure that they are plugging in their cars right.

    Though there have also been studies about range anxiety as being the more important issue to address, car manufacturers and marketers can not deny that charge anxiety exists. Plugging the car into the socket may not come as easy as charging your cellphone.

    Last May, everyone was looking at the figures being demanded by the fuel efficiency regulations of the United States which sets the bar at 35.5mpg by 2016. BMW X6 MThe number applies to the average of all the brands produced by the carmakers. Foreign marques though selling luxury cars in the US may have some way out of this stringent policy.

    The Obama administration may have some slack for the foreign luxury brands coded the German proposition by some lobbyists. The foreign manufacturers which do not sell more than 400,000 units annually in the U.S. may just be subjected to less rigid rules.

    Some of the brands which will obviously benefit from the loophole will be Mercedes-Benz, BMW, and Porsche. These are the same brands which have been opposing the proposed fuel efficiency rules ever since.

    Looking at the loophole though justifies its sense. Smaller car manufacturers are the least likely to be able to adjust to the cost since they don’t have low end vehicles which can pump their efficiency figures.

    Small volume of cars being produced means that the cost of improving the fuel efficiency of the fleet will be higher. The new policy anyway aims to save money and help the environment, but not to close down any car business.

    The Tesla Roadster may be considered as the king of the road when it comes to zero emission performance. The British firm Lighting Company wants to catch up and challenge the Tesla Roadster by working on a 700hp electric vehicle that will go on production by 2010.

    Lightning GT

    The engine of the next generation vehicles will be derived from the DNA of their first EV the Lightning GT.

    According to Lightning, the company will design and come up with several variants. This includes an off-roader SUV, a limo type saloon, and a sports car.

    The company wants to focus on the Lightning GT and deriving the power plants of the new members of their brood from it will allow them to release them to the market as soon as they are ready.

    The Lightning GT is expected to be released by spring of 2010 and orders for the units are coming. A third of the deposits are mostly from the United Kingdom alone. The specifications of the car though have not been finalized and the information disclosed to the media is very limited.

    Kawasaki BatteriesKawasaki Heavy Industries Ltd. (KHI) will start producing grid and transportation application versions of the Gigacell bipolar NiMH Industrial batteries

    The Gigacell was developed in cooperation with New Energy and Industrial Technology Development Agency (NEDO) of Japan. It offers a big capacity in storing energy which is made responsible by its high-rate structure, discharge ability and high rate charge. It used nickel hydroxide as its positive electrode while utilizing the metal hydroxide for its negative electrode.

    KHI is also designing a 280Ah stack with an enhanced charging and discharging rates. It has 2.5 kWh of aptitude and volumetric density of 40 Wh/L and 21 Wh/kg gravimetric density.

    Last December 2007, KHI declared that it had completed a verification test using a Gigacell pack on a railcar regenerative braking. The system was analyzed at the substations of the Osaka Subway.

    Kawasaki confirmed that the generated energy by the braking of a train could be accumulated and be reused to counterweigh for the voltage fluctuations that take place during start-up, operation, and jam-packed rush hours.

    Controlled Power Technologies suggests that smoke emissions from turbo charged diesel engines subjected to heavy loads, like negotiating a stiff climb on a low gear, may be eliminated using a cheap electric supercharger.

    CPT is a start up company based in the United Kingdom which explores development of carbon dioxide-reducing solutions that can be used with today’s vehicles.

    At the moment, the company is marketing three basic products: VTES or Variable Torque Enhancement SystemControlled Power Technologies which is a supercharging system; TIGERS a generator system dependent on exhaust turbine; and SpeedStart12 which is a starter generator system.

    Excessive particulate emission is a major issue in the transport industry especially when tougher guidelines and legislations will be in placed by 2012. The supercharger from CTS aims to address the root of the problem by supplying more air to the engine during transient events which may require addition power and fuel. The sufficient air will prevent production of soot which is caused by inefficient combustion.
