Bike idea appeals to the slouch in us

One of the two small turbines is visible below the front aerodynamic solar-panel. The center light detaches for use as a flashlight.

In shape or not, pedaling up a steep or long hill can knock the wind out of most of us. That is one reason, says designer Chen Chun Tung, we need bikes like the Wind-Solar Energy Bike. The design, he says, converts and stores wind, solar, and shock energy, along with muscle power into electricity so it can be used during tough climbs, or when just lazy. Four devices (an adjustable solar energy plane, a spoiler, the front fork, and front and back wheels) harness energy and store it in a battery, says Tung.

The adjustable solar energy plane mounts below the main frame but can be unfolded and mounted on a support over the rear wheel to expose more cells to the sun. The spoiler, fixed below the handlebars, combines a solar-cell coating and wind-driven generators. The aerodynamics of the spoiler is said to provide some lift, presumably to reduce rolling friction. And the spoiler also sports a removable headlight that can double as a flashlight.

A coil and magnet in each front-fork tine generates a current as the fork compresses and extends over bumps. The rider’s weight causes some oscillations, which passes the magnetic field over and off the coil, generating a current. Lastly, motor-generators are built into the front and back wheels.

Lynn Jurich, SunRun president, talks green jobs & future of solar on Fox Business News

The importance of a clean energy economy was visited time and again in President Obama’s State of the Union address.  With such strong support coming from the White House, we here at SunRun are very excited about what 2010 will bring for solar.  SunRun’s president, Lynn Jurich, spoke to Fox Business on Thursday about the future of the solar energy sector, as well as the hundreds of green jobs the solar industry has been able to create.



Not only has home solar become an affordable option for millions of homeowners, but it has also been able to create clean, permanent jobs.  According to research, for every six homes that goes solar, a green job is created — and that’s not including the other jobs created down the supply line.  And these are jobs created within the nation – here and at present.

Watch the Fox Business clip to hear more about green jobs, federal subsidies, and the future of solar.

Areva gets deeper into renewables with Ausra purchase

France’s Areva SA is known mostly as a designer of light-water nuclear reactors, builder of transmission and distribution systems, and a miner of uranium, so the announcement today that it has purchased 100 per cent of concentrated solar power company Ausra Inc. came as a surprise. Ausra, based in Mountain View, Calif., was founded by Canadian inventor Dr David Mills. Mills developed the underlying technology as a student and professor in Australia, but located the company in Silicon Valley as part of a major venture capital infusion from Khosla Ventures and Kleiner Perkins Caufield & Byers. Mills is currently the company’s chief scientific officer.

Areva said today that the acquisition marks its entry into the solar thermal power market, where it intends to be the leader. The market itself is expected to grow 20 per cent annually over the next decade. This is just the latest in a string of acquisitions and deals aimed at broadening Areva’s portfolio of renewable energy products and services. The company has been pushing heavily into biomass power and has been building biomass/biogas plants in the U.S., Brazil, India, Thailand and other countries. It is dabbling in hydrogen production and fuel cell systems, and through its acquisition of Germany’s Multibrid is trying to establish itself as a future leader in offshore wind.

It’s going to take big, deep-pocketed companies like Areva to really push deployment of solar thermal and other promising renewables, so this acquisition of Ausra is a good sign of where the market is heading. Given that the nuclear renaissance simply isn’t materializing as expected, it’s wise for Areva and other big energy conglomerates to hedge their bets.

Top 10 “Clean Energy” Topics to Keep an Eye On

Clean energy is one of the top topics in the world these days, in presidential speeches, economic growth plans and projections, international competition and cooperation, and even in Hollywood. We have seen rapid growth in wind power, rooftop solar, innovative financing, and much more recently.

Here is my list of the Top 10 “Clean Energy” Topics (some aren’t what I would consider the cleanest) to keep an eye on.

1. International Clean Energy Race

The “international clean energy race” may well determine who will lead the world economy in the future — “the nation that leads the clean energy economy will be the nation that leads the global economy” (Obama, State of the Union 2010). China is about to make the largest solar and wind projects in the world look like little LEGO projects and it seems like it is #1 or fast-approaching #1 right now. “Every day we wait in this nation China is going to eat our lunch. The Chinese don’t need 60 votes.  I guess they just need 1 guy’s vote over there – and that guy’s voted” (Republican Senator Lindsey Graham to 200 business leaders, 2010); “China now leads world in clean tech. Time for a Sputnik program to reclaim leadership” (Representative Steve Israel of New York, January 2010).

On the flip side of that, the cooperation-focused (rather than competition-focused) United Nations climate conference in Mexico that is supposed to keep the ball rolling from the Copenhagen Accord is something to keep an eye on as well (along with all of its lead-in and follow-up activity). In a sense, this can be combined with the clean energy race topic because it is intended to put everyone on the same track.

2. Climate & Clean Energy Bill in Congress

The US’ best bet at getting ahead in the global clean energy race and at providing a livable environment for our children and grandchildren might be the climate and clean energy bill that is inching its way through Congress. The public supports it. Hollywood is trying to get people to put the pressure on their representatives in Congress. And big business is putting the pressure on Congress. However, the coal and oil lobby and its Congressional robots are constantly trying to undermine the bill.

3. PACE Funding

Property Assessed Clean Energy funding started in Berkeley, California in October of 2007 and is on the move. What’s so special about it? It “allows private property owners to pay for energy efficiency and renewable energy projects through an addition to their property tax bill, overcoming the high upfront costs that prevent most property owners from investing in such retrofits.” People can avoid the high upfront costs of solar technology but can capitalize on the long-term benefits of it and save them money!

This is also a less controversial tool than broader initiatives like cap and trade, so one hopes that this becomes a real federal priority soon. Our own Susan Kraemer writes: “One very effective way to transition fast to clean power in a way that can bypass our Senate block on cap and trade, is to make PACE funding for renewable energy available to homeowners nationwide in the budget. Budget funding can be passed with a majority of just 51 votes like in other democracies.”

A UC Berkeley study found that there is “potentially a gigaton of greenhouse gas reductions to be made, at no cost to local, state, or federal governments from a $280 billion potential market in PACE solar funding in the US.” Cities and counties that are picking it up are seeing dramatic growth in solar power (e.g. “California’s Sonoma County which offered PACE starting in March in California recently reached an astounding 4% of power on the grid coming just from rooftop solar alone.”)

4. Distributed Solar Energy

Simply, distributed solar is “energy generated, stored and managed at the local level.” Distributed solar includes private installations (e.g. on the roofs of houses, businesses, etc.) which are actually more popular than utility-scale solar these days as well as things like small photovoltaic farms. Distributed solar projects can be combined into larger power purchase agreements for a big bang as well.

Distributed solar has several key advantages over large-scale solar projects: quicker implementation, better ability to upgrade or innovate to more efficient technologies, and much more flexibility in siting. Due to all of its benefits and increasingly cheap solar technology, distributed solar seems to be booming and is getting more and more people’s attention. As the New York Times reports, “Over the past few weeks, some 1,300 megawatts’ worth of distributed solar deals and initiatives have been announced or approved. At peak output, that is the equivalent of a big nuclear power plant.”

5. 10 Million Solar Roofs Bill

New bill just introduced to Congress from Independent Bernie Sanders proposes incentives and tax rebates aimed at getting 10 million solar roofs and 200,000 solar heaters up and running over the next 10 years. Keep your eye on that!
