First off, HAPPY New Year to everyone who comes here.
Second, some big changes are coming to this Blog. After 6 years of 5 day a week posts we have covered many of the things we set out to cover. Global Warming has been accepted by everyone who does not own stock in a carbon company. Renewable Energy generation is on the rise. Environmentalism is becoming the word of the day. Not that this blog claims to have caused that but we have been a part of it. So, CES has decided to become an intermittent poster. That is when something big happens. So, this is not our final post just posting at a more relaxed pace.
Ultra-efficient home design combines state-of-the-art, energy-efficient construction, appliances, and lighting with commercially available renewable energy systems, such as solar water heating and solar electricity. By taking advantage of local climate and site conditions, designers can incorporate passive solar heating and cooling and energy-efficient landscaping strategies. The intent is to reduce home energy use as cost-effectively as possible, and then meet the reduced requirements with on-site renewable energy systems. To learn more about the details of designing and building an ultra-efficient home, visit Building America Resources for Energy-Efficient Homes.
Another strategy for achieving an ultra-efficient home is to build or remodel to the rigorous, voluntary Passive House standard. The result is an extremely well insulated, airtight structure with dramatically reduced heating and cooling requirements.
Villa Åkarp: A super-efficient home that scores an A+ in surplus energy production
After construction wrapped up in 2009, Villa Åkarp’s energy-plus ambitions have come true: The super-insulated Swedish home’s rooftop solar system generates an excess of 600kWh annually.

Keeping up with today’s mini-trend of (shockingly) non-IKEA-related housing news coming out of Sweden, I thought I’d revisit a notable residential building project located outside of the city of Malmö that I first made mention of way back in November 2009.
When I intially caught wind of said project, Villa Åkarp, it was under construction with the lofty ambition of becoming an energy-plus (or positive) home. In other words, the three-bedroom, two-bathroom home is not only influenced by stringent Passivhaus building standards that focus on energy recovery and conservation (high amounts of insulation, triple pane windows, thermal recovery, strategic building orientation, etc.), but energy generation as well. Thanks in part to a 32-square-meter rooftop photovoltaic array, the now-completed residence produces significantly more energy than it consumes. In all, the airtight home’s solar panels produce around 4,200 kilowatt hours (kWh) of juice per year (mainly during the summer months) with a surplus of around 600kWh annually that’s fed back into the grid in a partnership with local green utility provider E. ON. That’s enough energy to power another energy-efficient home for two months.
Go there and then to the original to read. More tomorrow.
One farm in the Ozarks is the location of a series of unique experiments in sustainable living. If these experiments prove successful, it would greatly affect the future of sustainable technologies and how people think about building their homes. KSMU’s Shane Franklin had the opportunity to tour the farm, and has this story.
Rockspan Farm, the home of Dan and Margy Chiles, is unique in so many ways. They wanted to build a farm that could be an example to others, and a test lab for experimental technologies they’ve been personally developing over the years.
“We are trying a number of new technologies here to make houses more efficient and to make a livable space without having to burn a lot of coal.
RockSpan is the name for our 12 acre farm and house in western Greene County, Missouri.
The project is the West end of Division street, 11 miles from Springfield, Missouri. The colorful plan below shows the family farm: approximately 227 acres outlined in red with a possible land use plan. Our 12 acres are inside the larger farm.
Go there, read and see all the pretty pictures. More tomorrow.
We get these claims all of the time, “A wind turbine for your roof”. About the only place that is true is on grain bins on a farm out in the country. I can neither testify that these turbines work or that they do not. What I can say is Merry Christmas and a Happy New Year. This blog will be closed until next Wednesday.
The Wind Sphere™ relies on its “wind tunnel” effect known in physics as the Bernoulli Principle. While the rest of the wind industry generates energy through the use of free-stream wind, the Wind Sphere™ captures and amplifies the wind, which produces more kilowatt-hours (kWh). As wind encounters the Wind Sphere™ shroud, it becomes concentrated creating increased velocity and in turn, more power. By amplifying the natural wind speed, the Wind Sphere™ is able to produce more power from a smaller footprint. Proportionally, the Wind Sphere™ has the smallest footprint with the largest amount of power output in the industry. Because of these attributes, the Wind Sphere™ is uniquely designed to produce energy in urban, populated areas with space constraints.
The inverter is IEEE 1547 compliant and UL 1741 certified.
Worldwide Turbine Certification
The Wind Sphere is currently in the process of the stringent IEC-61400-2 testing, also know as the Standard for Small Wind Turbines testing. Exhaustive field testing will be conducted by a Certified AWEA testing firm to verify performance and real world endurance.
“With the Wind Sphere, building owners everywhere can now consider being a part of the renewable energy picture.”

SAN MATEO — In a worrisome sign for the cleantech sector, SolarCity postponed its IPO plans late Tuesday, perhaps to reduce the price of shares below its original range.
The delay came after SolarCity Chairman Elon Musk, the CEO of Tesla, made the unusual move of stepping in to buy $15 million worth of shares, or 12 percent of the total offering. Musk’s willingness to put more skin in the company he helped found was intended to boost investor interest.
It wasn’t clear Tuesday evening if the IPO is simply being delayed for a day or two or if there are more serious problems that could lead the company to shelve plans to go public. SolarCity CEO Lyndon Rive could not immediately be reached for comment, and calls to the company’s press office were not returned.
Solar companies, particularly manufacturers, have been battered for months. The “solar curse” began with the bankruptcy of Fremont solar manufacturer Solyndra in 2011, which cast a long shadow over the industry. In April, Oakland-based BrightSource Energy canceled its IPO plans at the final hour.
Never one to let a good heading get away from me, it’s time to turn the evil power of tornadoes into something good — namely, green energy. And thanks to The Thiel Foundation’s funding program Breakout Labs, a new grant has been awarded to harness the power of atmospheric vortexes.
“The power in a tornado is undisputed,” said Louis Michaud, Canadian engineer and designer of the Atmospheric Vortex Engine (AVE). ”My work has established the principles by which we can control and exploit that power to provide clean energy on an unprecedented scale.
“With the funding from Breakout Labs, we are building a prototype in partnership with Lambton College to demonstrate the feasibility and the safety of the atmospheric vortex engine.”
Michaud’s design sees warm or humid air introduced into a circular station wherein it takes the form of a rising vortex which drives multiple turbines.

WASHINGTON — Nearly 4 out of 5 Americans now think temperatures are rising and that global warming will be a serious problem for the United States if nothing is done about it, a new Associated Press-GfK poll finds.
Belief and worry about climate change are inching up among Americans in general, but concern is growing faster among people who don’t often trust scientists on the environment. In follow-up interviews, some of those doubters said they believe their own eyes as they’ve watched thermometers rise, New York City subway tunnels flood, polar ice melt and Midwestern farm fields dry up.
Overall, 78 percent of those surveyed said they thought temperatures were rising and 80 percent called it a serious problem. That’s up slightly from 2009, when 75 percent thought global warming was occurring and just 73 percent thought it was a serious problem. In general, U.S. belief in global warming, according to AP-GfK and other polls, has fluctuated over the years but has stayed between about 70 and 85 percent.
