There’re strange brewings in the auto industry. President Obama once remarked that “unless we free ourselves from a dependence on these fossil fuels and chart a new course on energy in this country, we are condemning future generations to global catastrophe.” Fresh off its government bailout, General Motors has devoted “significant resources” to the Chevy Volt, an "Extended Range Electric Vehicle" set for release in 2011. Obama’s response?
Tinkering with Earth's climate to chill runaway global warming — a radical idea once dismissed out of hand — is being discussed by the White House as a potential emergency option, the president's new science adviser said Wednesday. That's because global warming is happening so rapidly, John Holdren told The Associated Press in his first interview since being confirmed last month. The concept of using technology to purposely cool the climate is called geoengineering
To follow up on an earlier story, congress has urged the EPA to drop its SSL Energy Star criteria. A letter, signed by nine congressional members, encourages EPA administrator Lisa Jackson to defer to the DOE on Energy Star. The letter makes mention of “the current state of affairs, in which two federal agencies have put forth two separate standards,” and that, “The overlapping standards are creating uncertainty in the industry”
In response to an Obama Administration auto task force report, Plug In America on Tuesday proposed a plan to make GM’s Chevy Volt and other plug-in cars more affordable, noting that most advanced new technologies are initially more costly. California law requires that the Volt and other plug-in hybrids come with a 10-year warranty. To ensure this longer life, automakers are as much as doubling the size of the battery pack, increasing cost to manufacturer and consumer.
Advanced technology vehicles have yet to gain a foothold in the mainstream auto industry. Hybrids boast a fuel economy upwards of 40 mpg, but are too pricey for your average consumer. Similarly, “clean diesel” sports high MPG ratings, but diesel is prohibitively expensive. The more exotic ATV’s (air-cars, biodiesel, solar) are aesthetically morose. Pure electric vehicles (PEVs) lack the necessary infrastructure to support them. Welcko’s Mogwai Electric Vehicle (or MEV) is the first ATV with potential mainstream viability
The California Energy Commission (CEC) is moving ahead with a proposal that could make Plasma TVs legally obsolete. Based on the 2008 Report, “Draft Efficiency Standards for Television” (which drew heavily from Pacific Gas and Electric Company findings), the proposal would set a cap on the maximum active mode power usage (watts). This would effectively ban the sale of Plasma, DLP, rear projector, and certain LCD TV’s in California
Tata Motors has unveiled the world’s cheapest car, with potential for a vast standard of living increase. And Greenpeace doesn’t like it. The same organization that supported a ban on chlorine in drinking water feels that the mass proliferation of cheap automobiles is a bad thing. Despite its eco-friendly 47 MPG rating, the Tata Nano is seen as a threat to the environment. Why? Because lots of people want to buy them.
Day after day, reports of the dangers of climate and climate change circulate in the news, often filled with confusing data and debate. In an effort to improve understanding of climate science, a group of government agencies has combined efforts to produce "Climate Literacy: The Essential Principles of Climate Science."
A lithium-ion battery electrode described this week in the journal Nature can deliver electricity several times faster than other such batteries. It could be particularly useful where rapid power bursts are needed, such as for laser weapons or hybrid race cars. Test batteries based on the new electrode--developed by Gerbrand Ceder, a professor of materials science at MIT--can be discharged in 10 seconds.
In 2007, Al Gore shared the Nobel Peace Prize for his efforts to “build up and disseminate greater knowledge about man-made climate change.” In his Oscar-winning documentary, An Inconvenient Truth, Gore screeched, “The scientists are virtually screaming from the rooftops now. The debate is over! There’s no longer any debate in the scientific community about this.”
Arizona State University’s Flexible Display Center (FDC) recently unveiled the world’s first flexible touchscreen display. Developed in conjunction with E Ink Corporation and DuPont Teijin Films, the active matrix display is capable of real-time user input, and can send and receive information. The applications for such a device, particularly in the military sector, are endless
Hundreds of demonstrators are urging Congress to pass legislation to reduce greenhouse gases, and they're using the Capitol power plant as a symbol of the problem. Despite attempts by lawmakers to clean up the power plant in southeast Washington, it still burns coal and accounts for a third of the legislative branch's greenhouse gas emissions. Monday's rally on Capitol Hill was being followed by a march to the power plant, where some demonstrators planned to block entrances and get arrested.
Shai Agassi, CEO of Better Place, wants to make electric cars viable. His solution? Spread battery-swapping stations throughout the world, using a fee structure similar to cell-phone contracts. According to Better Place’s site, “The batteries of a zero-emission vehicle need three things in place for optimum functionality: charging spots, battery switching stations, and software that automates the experience.” Their solution is a network of stations where depleted batteries can be swapped out for fresh ones.
This "compromise" is an example of the misguided cuts that have been made in the stimulus package in the name of savings. "Clean Coal" and Nuclear power are among the best alternatives to oil we have, and to cut funding for these important technologies is shortsighted. "Clean Coal" and Nuclear power are among the best alternatives to oil we have, and to cut funding for these important technologies is
Obama’s position on tailpipe emissions presents a strange paradox: traditional supporters of states’ rights are clamoring for one national standard, while federalists want the states to decide. It seems that we’ve entered bizarro world. But it goes deeper. Allowing states to set their own emissions standards is a thinly-disguised attempt to impose higher national standards through backdoor means.
As readers of ECN well know, Americans are purchasing new and improved electronic products faster than ever—and thereby creating a record amount of electronic waste. What you may not know is that 50% of the e-waste generated in the European Union and North America is now exported to developing countries such as India, China and Africa.
President Obama has ordered the EPA to “review” its denial of California’s request for exemption to federal emissions standards. On Monday, January 26th, Obama gave a press conference relating to, “Jobs, Energy Independence, and Climate Change.” Among other things, he spoke about America’s dependence on foreign oil, the proposed American Recovery and Reinvestment Plan, and the aforementioned EPA denial.
The history of portable electronics is one of decreasing size, both for the devices themselves and the batteries to power them. A while back, I reported on the Quad A battery—specifically, Energizer’s push to make the Quad A more commercially available. The Quad A was commercially available (though not prevalent) since 1989. Similarly, the technology behind Energizer’s latest offering, the Zinc Air Prismatic Battery (or ZAP for short), has been around since 1991.
Hipsters of the world rejoice! Mini has announced the greatest thing since arthouse theater—an electric version of the Mini Cooper. Unveiled at the 2008 Los Angeles Auto Show, the Mini-E is the first highway legal all-electric vehicle. Amazingly, the Mini-E is heavier than its internal combustion engine (ICE) counterpart (curb weight of 3,230 vs. 2,546 for the ICE). This will satisfy those who feel greater mass equals greater safety. Despite its added bulk, the Mini-E has even greater front/rear weight balance than the ICE.
In a move sure to ignite debate on this side of the Atlantic, the European Union approved the phasing out of incandescent bulbs by 2012. Here in the US, we’re debating which technologies should be allowed to earn a label (Energy Star). Over in Europe, they’ve ended the discussion with multinational governmental action. By following the commission’s proposal, EU citizens will save close to 40 TWh per year, and emissions will go down by 15 million tons of CO2 (according to the European Commission). But there’s a larger issue at hand: should government have such control of industry?
Betz’ Law (culled from its namesake, Albert Betz) is a theory for flow machines. From this theory we derive the Betz Limit, that is, “the maximum possible energythat may be derived by means of an infinitely thin rotor from a fluid flowing at a certain speed.” In windmills, this equates to how much electricity can be harvested from the wind energy. Current technology allows turbines to capture a maximum of 59 percent of the energy in wind
This achievement not only speeds us forward in the development of real-world solid-state lighting, it demonstrates that LED-based tech is not the only game in town.Delivering a light yield of over 60 lumens/watt, an organic light-emitting diode (OLED) white light emitter from BASF and Osram Opto Semiconductors also meets international Energy Star SSL Standard with regard to color requirements.
When we think of advanced technology vehicles, we usually conjure hybrid electric, fuel-cell, and solar cars. But the term, in fact, encompasses a wide-variety of off-the-wall designs including our most fundamental resource- air. Compressed air, as a technology, is nothing new. Seen in everything from power dusters to UPS’s, compressed air has a wide scope of application. But as an ATV variant, compressed air is relatively new (and unproven). French-based Motor Development International (MDI) has, since 1991, taken the lead in creating a viable air-powered vehicle.
A new technology aims to extract energy from that which covers 75% of the Earth— water. Michigan-based Vortex Hydro Energy is researching the natural motion of ocean currents; in particular, how currents interact with cylinders. Take offshore oil rigs, for example. When water impacts the cables that hold the platforms in place, it creates small vortices. When each vortex dissipates, it creates a vibration that poses a long-term risk to the rig’s structural integrity. But ocean engineer Michael Bernitsas, founder of Vortex Hydro, believes these vortices can be harnessed.
Regular Efficiency Zone readers know that photovoltaics is a very inefficient technology. While the technology is environmentally-friendly, and the energy source (the sun) will be viable for billions of years, the conversion process (and viability) is undercut by a number of factors. These include shade, dirt, and panel-to-panel mismatch. In addition, detractors of the technology point to its high cost, but this is a socio-economic factor that won’t be solved by science alone. But scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have made a huge technological leap.
