The challenge set by Ford Global Technologies is to design a Model-T for the 21st Century - an inexpensive, innovative and sustainable car. Deakin University is the only Australian university and one of only five worldwide invited to participate in the Challenge, part of the celebrations for the 100th anniversary of the fabled Model T; the car that changed the 20th Century. Deakin University's 'under wraps' design for the Ford Global Challenge left for Detroit on 29th August carried by Deakin's Tim de Souza (Chief Design Engineer) and Stuart Hanafin (Portfolio Coordinator). Deakin's project is code-named T2 ('TSquared').

The Scottish Government has created one of the biggest international innovation prizes in history - a £10 million challenge for advances in wave and tidal energy. At a ceremony this week in historic Edinburgh Castle, details of the 'Saltire Prize' were revealed to leading scientists, environmentalists and potential entrants after being finalised by a panel of international experts who comprise the prize Challenge Committee. Dr Anne Glover, Scotland's Chief Scientific Adviser and Chair of the Challenge Committee, said the Saltire Prize will be awarded to the team that can demonstrate in Scottish waters a commercially viable wave or tidal energy technology that achieves a minimum electrical output of 100GWh over a continuous two year period using only the power of the sea and is judged to be the best overall technology after consideration of cost, environmental sustainability and safety.

Last week, Vice President Al Gore presented the American people with a challenge: meet 100% of our electricity needs through renewable energy within 10 years. Al would be the first to acknowledge this is not a minor task. And yet it is an urgent one, a challenge that will require a transformation in how we invest our time and money, and how we view ourselves.

Nature Challenges Climate Change Alarmists

There are times in the history of our nation when our very way of life depends upon dispelling illusions and awakening to the challenge of a present danger. In such moments, we are called upon to move quickly and boldly to shake off complacency, throw aside old habits and rise, clear-eyed and alert, to the necessity of big changes. Those who, for whatever reason, refuse to do their part must either be persuaded to join the effort or asked to step aside. This is such a moment. The survival of the United States of America as we know it is at risk. And even more - if more should be required - the future of human civilization is at stake.

Frontline's "Heat" is not just good, but bordering on "scary good", and should instantly vault to the front ranks of journalism devoted to global warming. I watched "Heat" last night, and was extremely impressed with the production's overall approach to the topic as well as how often the primary on-screen journalist, Martin Smith, cut right to the core of an issue with a tough, point-blank question.[1] Even as some parts of the show made me ache as it described just how daunting this challenge is, I wanted to cheer the tough, unblinking stance the show took in treating the topic.

SLE stands for Systemic lupus erythematosus (SLE).It is a chronic inflammatory disease of unknown cause that affects multiple organ systems. Immunologic abnormalities, especially the production of a number of antinuclear antibodies, are another prominent feature of this disease. Its multisystemic manifestations and the complications from the use of immunosuppressive agents make the diagnosis and management of this entity challenging.

The U.S. environmental movement is failing - by any measure, the state of the earth has never been more dire. What's needed, a leading environmentalist writes, is a new, inclusive green politics that challenges basic assumptions about consumerism and unlimited growth. by james gustave speth A specter is haunting American environmentalism - the specter of failure. All of us who have been part of the environmental movement in the United States must now face up to a deeply troubling paradox: Our environmental organizations have grown in strength and sophistication, but the environment has continued to go downhill, to the point that the prospect of a ruined planet is now very real. How could this have happened?

I must admit that I have been a bit nonplussed to see that the peak oil community seems to share the oil industry's dismissal of wind power as irrelevant and useless in the face of the currently energy challenge (maybe I am unfairly judging from a few individuals' comments, but it's definitely an existing undercurrent in the community). So, in reaction, let me put up here a few arguments that suggest that wind could play a major role in solving our current energy woes - not a silver bullet, but rather more than a side show. First, the "wind is too small to make a difference" argument: well, so was nuclear, until it got big enough. Wind is following the exact same growth trajectory [as shown below].

Understanding wind energy can be a challenge. But it is no more complicated than the choices we are making on transportation. And just like those choices, wind is great for Pennsylvania's economy as well as our environment. Pennsylvania wind farms generate power about 70 percent of the time. But the amount of power is variable. That's why it is rated at 30 percent of capacity. It's like having a car that can go 100 mph but your average speed is much less.

KINGSTON, Ontario, Jun 25 (IPS) - North America's abject failure to meet the challenge of climate change has been "un-American", environmentalist and scientist David Suzuki told delegates Tuesday at the World Wind Energy Conference, the first ever in the region. "We're facing an ecological crisis, a crisis far, far worse than Pearl Harbour," Suzuki said. Twenty years ago this week, one of the United States' leading scientists warned Congress of the imminent danger of climate change and said that waiting decades to take action was too risky. Now James E. Hansen of the National Aeronautics and Space Administration has published new research indicating that greenhouse gas concentrations have pushed the climate near a dangerous tipping point that will unleash far-reaching changes in the atmosphere and oceans that could take millennia to reverse.

PETROL should be included in Australia's carbon emissions trading scheme, but low-income households should be compensated for higher power and fuel bills, the nation's top climate change expert has warned. Issuing a stern challenge to the Rudd Government to include petrol in the scheme, when it begins in 2010, Ross Garnaut warned of dire consequences for Australia's natural icons unless urgent and decisive action is taken.

It wasn't the variable of available sunshine in their suburban Chicago neighborhood that inhibited Sarah and Kiril Lozanov from going solar. Rather, it was the challenge of cost - and of earning homeowner's association approval for the new construction solar would warrant on their condominium rooftop.

The US Department of Energy (DOE) issued a Funding Opportunity Announcement (FOA) for up to $6 million over two years (FY09-FY10), subject to annual appropriations, to address wind development technical challenges and market acceptance barriers as outlined in the "20% Wind Energy by 2030" report published in July 2008. The announcement will address six topic areas: (1) turbine research, development and testing; (2) distributed wind technologies; (3) market acceptance efforts; (4) environmental research and sitting strategies; (5) transmission analysis, planning and assessments; and (6) workforce development.

Technology Review reports that the idea of hybrid gas-solar thermal power plants is being considered for coal fired plants now - Cutting Coal Use with Sunshine. Feeding heat from the sun into coal-fired power stations could turn out to be the cheapest way to simultaneously expand the use of solar energy and trim coal plants' oversize carbon footprints. At least that's what the Electric Power Research Institute (EPRI), a nonprofit organization backed by the electricity industry, is hoping. Last week, the institute launched a nine-month, $640,000 study to pin down the scale of the opportunity and the engineering challenges involved with making these seemingly disparate technologies work together. The study will examine the potential use of solar-thermal technology at a pair of coal-fired power stations, in New Mexico and North Carolina.

CleanTechnica has a post from San Francisco mayor Gavin Newsom on the city's proposal to build a wave power plant offshore - Wave Energy to Bring Power and Jobs to San Francisco. Today, San Francisco took a meaningful step toward turning the promise of renewable ocean energy into reality. We submitted a preliminary permit application to the federal government to develop a wave power project off our coast that we believe can generate between 10 to 30 megawatts of energy, with potential of up to 100 megawatts. When this project is fully operational, upwards of 100 jobs could be created in San Francisco. Ocean power is a true "game changer" in the area of renewable energy. When wave and tidal power technologies reach commercial scale, they are expected to be able to provide thousands of megawatts of power to our coastal communities, dramatically green our energy portfolios and create thousands of new American jobs. In San Francisco, we've been doing our part to spur these technologies by aggressively advancing tidal and wave power pilot projects. We are 100% committed to this challenge. Wave power is not a new concept. In 1887, San Francisco Mayor Adolph Sutro recognized the power of San Francisco's waves and built a wave catch-basin to harness the ocean's power. Over the next century wave power development took a backseat to our dependence on oil, with oil platforms built along our coasts to feed our oil addiction.

The challenges our society faces with depleted energy resources, water shortages, soaring food costs all point to environmental solutions.
