Bloom Energy: Big Dreams. Big Backers. Big Success? February 24th, 2010
Bloom Energy had the official public unveiling of their solid oxide fuel cell technology today in Silicon Valley. After years of flying under the radar as a stealth start-up, the company made it’s debut on the world stage with a bang. California governor Arnold Swarzenegger was on hand as was former Secretary of State Colin Powell, Google co-founder Larry Page, venture capitalist John Doerr, and executives from eBay, Walmart, Coca-Cola, and FedEx. These companies have been generating energy from Bloom Boxes (units that contain stacks of these fuel cells) on a trial basis. According to TechCrunch, “Five Bloom energy boxes about the size of a parking space each now provide 15 percent of the power at eBay’s campus. Walmart is testing the boxes in two locations where [they are] carrying 60 to 80 percent of the energy load of an entire store.” A video describing the technology can be found here. Below is Bloom Energy’s explanation of how their technology is more flexible and better than “hydrogen” fuel cells. Read the rest of this entry »
Bloom Energy Boxes: Replacing the Grid with a Clean Energy Power Station for Every House? February 22nd, 2010
Green energy start-ups often promise revolutionary technology in going after the Holy Grail of clean, cheap, efficient, and abundant energy only to disappoint in the end. What makes Bloom Energy and the claims that they make any different? Well, perhaps nothing. But perhaps they will back up their talk when a mysterious countdown on their homepage is explained on Wednesday. Featured recently on 60 Minutes, the company is the product of a foray into business by former NASA engineer KR Sridhar. The origin of the technology goes back to a project to produce oxygen for astronauts on Mars. Once that program was scrapped by NASA, Sridhar reversed his design to make a fuel cell that uses oxygen and fuel to produce electricity. Read the rest of this entry »
Colorado Governor Calls for 30% Renewable Energy Target February 6th, 2010
Despite announcing his intention not to seek a second term as governor of Colorado, Governor Bill Ritter has continued to pursue a clean energy future for the state. While many states have mandates of 20% or 25% electricity generation from renewable energy sources by 2020, Ritter is pushing ahead toward 30%. Ritter’s goal is one of the most ambitious, ranking in the top three states as measured by a percentage of electricity production. Read the rest of this entry »

Inefficient Devices and the Laws of Thermodynamics January 23rd, 2010
As a science teacher I can tell you that people find science scary. Perhaps you already knew that. They think it is something they “can’t do” or “don’t get.” They may say they do not have a scientific brain. I can also tell you that these are entirely untrue. Real world, personally accessible examples, instead of theoretical situations, help make the connection to the here and now. For instance, the title of this post “Inefficient Devices and the Laws of Thermodynamics” would probably be enough to scare off most readers. However, by thinking about your own home, this scientific concept comes to life. Read the rest of this entry »

Update: Solar Roadways January 21st, 2010
A few months ago Solar Roadways was the recipient of extra attention in the blogosphere. 2nd Green Revolution did its part and brought you news of this company as well. All of the attention resulted in a redesigned website with flash animation. The older version of the site (one of which can be seen here) lacked the “Wow” factor that is now a part of the new site.
While the revamped site contains a wealth of information on the benefits of solar roadways in an attractive, easy to access format, there does not seem to be much movement on the development and implementation side. Read the rest of this entry »
Can The Smart Meter Change Our Behavior? January 18th, 2010
One tool currently on the market that encompasses both the technological and behavioral changes needed is the smart meter. Several posts on 2nd Green Revolution have dealt with this topic. Earlier this month on NPR, reporter David Kestenbaum interviewed Dan Reicher, software developer at Google. Host Steve Inskeep provided the following introduction: Read the rest of this entry »

The Coming Trouble With Clean Energy: Rare Earth Elements December 27th, 2009
Yesterday’s post about fake and real Christmas trees and menorahs developed out of several conversations during the holidays, but was precipitated by an article in The New York Times about the use of so-called rare earth elements in the manufacture of clean energy components. Cradle to cradle design would suggest that all materials used in consumer products ought to be capable of serving some function once the original purpose of the object has long passed. This design philosophy necessitates making components for consumer goods out of materials that can return to the ecosystem with toxification of the soils, water, or atmosphere.

Test Your Green IQ, Part 3 December 9th, 2009
Here are today’s two quiz questions taken from the Wall Street Journal’s environmental knowledge test. Previous Green IQ posts can be found here.
Household appliances and electric gadgets suck up lots of energy in standby mode just to keep the clock on and the machine ready to go at a moment’s notice. In rough terms, the amount of electricity wasted that way in the U.S. each year is equivalent to the output of:
A. 0.8 nuclear power plants
B. 1.8 nuclear power plants
C. 8 nuclear power plants
D. 18 nuclear power plants Read the rest of this entry »
Solar Decathlon Results: Germany Repeats as Champions November 29th, 2009
I am remiss to post this so late but still wanted to wish a quick and belated congratulations to Team Germany for winning the 2009 Solar Decathlon that was held last month on the National Mall in Washington, D.C. The annual contest challenged 20 student teams to design, build, and operate the most attractive and energy-efficient solar-powered house. Full results and details are here, or click on the image below. The following synopses of the three top houses are from the Solar Decathlon website.
Overall Winners
First Place: Team Germany (Technische Universität Darmstadt)
The 2007 champions did it again! Team Germany focused on producing surplus energy by using the maximum overall building dimensions allowed, applying photovoltaics to every available surface, and pushing the envelope with new technologies. The team walked away with the Net Metering contest and performed well in several others, including Architecture, Lighting Design, Comfort Zone, and Hot Water. Demonstrating that they are true champions, members of Team Germany were extremely gracious in their victory and recognized the work of their peers.
Updates at New Belgium Brewery November 26th, 2009
Yesterday I had the opportunity to tour New Belgium Brewery for the second time in the last 14 months. Earliest this month, 2nd Green Revolution carried a write up of the first visit. Subsequently, we have written several other stories about (or mentioning) the brewery. In yesterday’s visit there were several new features that were mentioned on the tour, and a few that I had not known of previously. Read the rest of this entry »
