Power-One Commercial Scale Inverter in the Boots Lab

Seriously, our MegaLab is bursting at the seams with super awesome solar stuff! One of the latest to arrive is a Power-One Aurora 10.0 480V commercial scale inverter! Not only is this inverter efficient, it’s stylish too. With integrated DC & AC switches, this three-phase inverter is uniquely designed to control the performance of PV panels, especially during periods of uncertain weather. (We are also really happy to receive the 10.0’s single phase little brother, the “3.0”! It’s just as stylish as the big 10.0, but smaller.) But Power-One does more than build beautiful inverters, they also make AuroraVision, precision monitoring equipment for larger systems. Power-One’s.

New ‘Artificial Leaf’ is a Real Gamechanger

Green solar technology that’s shaped to imitate nature has been a somewhat common thing over the last few years. However, instead of constructing a set of buildings meant to blend in and look like trees, as people did at the start of the nature building trend. Now scientists are beginning to look at natural, highly beneficial processes – in this case photosynthesis – and attempting to replicate nature’s solar successes.

Substantial progress has been made in this area. Recently researchers at MIT announced that due to a major breakthrough this year they have finally made the solar ‘artificial leaf’ a reality. The leaf is able to split apart the oxygen and hydrogen that make up water. It does this by opposing catalytic bonds on different sides of the leaf to draw the elements apart. It all sounds very complicated; mostly because it is, but it is an astonishing breakthrough whether its one we can fully understand the science behind or not. Once the two elements have been separated they can then be used as a source of energy.

The successful creation of the artificial leaf has reignited people’s imaginations. What we can do using technology grows with each new day. A worldwide group of scientists have looked at the groundbreaking artificial leaf and speculated that the technology can be used to create even more effective photosynthesis like reactions generating even more solar power. A leaf in nature can separate and efficiently process a large amount of different types of energy. The artificial leaf is the first major step to taking advantage of all the different types of energy the sun has to offer and replicating the already safe and clean solar reactions in nature.

This ‘artificial leaf’ development lead one professor, James Barber, who is unconnected with the project to comment, “there is no doubt that their achievement is a major breakthrough which will have a significant impact on the work of others dedicated to constructing light-driven catalytic systems to produce hydrogen and other solar fuels from water.”

It’s pretty much unanimous that the artificial leaf represents a major development and one that has even more amazing potential for growth and innovation. Stay tuned for more groundbreaking developments in solar power potential because they are everywhere.

300 megawatts of roof-top, commercial PV installations to be installed in North America in just this quarter!

The good people at Solarbuzz report that  Q4’11 installations will be about 800 Mega Watts  of PV capacity in North America.

Solarzuzz also reports:

In Q4’11, ground-mount installations are forecast to have 38% of the market, followed by building-mount, non-residential systems (>100 kW), which will have 37% of the market. The ground-mount segment benefited from demand from Ontario and from large-scale installations in California and Arizona geared toward meeting the state RPS requirements.

If our solar-powered calculator is correct – that means about 300 megawatts of roof-top, commercial PV installations in just this quarter!

Boots on the Roof is running not one, but THREE new courses to support the growing volume of commercial projects:

If you are planning to expand into Commercial Rooftop Solar in 2012, we’d like to talk with you about how our new courses may support your plans.

New Solar Tower Generates Power 24/7

Everyone wants a solar plant that can generate power 24/7, in fact some consider the ability to generate solar power at night the Holy Grail. Well, time to drink of the healing water because a Spanish solar plant has found a way to make a solar plant generate power throughout the night – using energy storage.

The massive solar plant takes up 457 acres of beautiful Spanish countryside. However, it puts these acres to good use placing large mirrors in circles around a central tower at which they can direct their sunlight.

The development of the project was done Torresol Energy – a joint project done by the energy companies Sener and Masdar. The technology is different from many other focused solar thermal plants. Instead of heating and burning oil the Gemsolar plant heats molten salt. As the salt heats up it gives off steam that is then used to power a turbine. The brilliant part about the design is that the intense amount of heat directed to the molten salt will create a lot of excess heat which can then be stored in a molten salt tank to be used for power during the night – or when the weather gets cloudy.

Due to the fact that no fuel is burned, the solar plant will likely save close to 30,000 in carbon emissions each year. It will do this while producing close to 20 megawatts of energy and providing 27,500 households in Southern Spain with clean solar power.

Perhaps the most exciting part about this is that the technology will likely come to the United State sand other major countries soon. I should have more information on the specifics in the coming days or weeks.

The new mass solar plant designs are innovative, but not a replacement for the older rooftop solar panels. All these are necessary to power our society. Any new form of clean energy must be welcomed into the fold. Let us hope this new tower rises over countryside’s everywhere soon.

Animal Expert Offers Pet Flood Safety Suggestions

(PRWEB) January 12, 2005

When disaster hits the mountains of southern California it is serious business. Only three highways lead in and out of the Big Bear Valley and this week’s storms have created havoc.

In October of 2003 wildfires closed two of those roads down. In January of 2005 all three highways closed and numerous other threats endangered residents and visitors to the southern California mountain resort.

According to mountain resident and author Diana L. Guerrero, “The main problem is that people were not prepared for such severe weather systems. This time of year we have a heavy load of visitors and their lack of understanding towards drastic changes in weather conditions and navigating in them complicates matters.”

Lack of preparation and understanding translated into two hundred cars stranded on an area of road called the “Arctic Circle.” A tour bus, failing to heed chain restrictions, blocked the highway and put motorists at further risk to mud and rock slides. Heavy snow and ice required snow cat rescues and the evacuation of motorists who were then housed in emergency quarters in the valley. The highway remains blocked until those vehicles can be removed.

Fawnskin mountain residents were isolated when flood waters covered the highway. Downed trees and slides blocked alternate routes out. Roads turned to rushing rivers.

In Big Bear Lake and other areas the snow berms, walls of ice created by workers clearing snow from the main roads, formed channels for water, flooded roads and cut deep into the asphalt.

The torrential currents flooded areas and blocked drains–contributing to the flooding of businesses. Heavy snow, followed by rain, collapsed roofs and inflicted water damage to public buildings.

Abandoned cars also posed problems. Guerrero said, “Unfortunately people do not realize the risk that deep snow or moving water poses. Cars attempting to cross the deep torrents often stall and create more problems by blocking the roads and creating the need for motorist rescue. People attempting to drive on roads covered in knee deep snow stranded themselves, blocking an alternate route, and created a heavier load for emergency service personnel.”

But the mountain residents were not the only people impacted by the recent storm conditions. The recent flooding across California impacted humans but it also created devastating problems for animals.

Guerrero said, “Pet owners and animal professionals can take steps to insure pet safety and avoid serious problems before the threat of disaster, specifically flooding, impacts their homes or businesses.”

Guerrero is the author of the booklet, “Animal Disaster Preparedness for Pet Owners & Pet Professionals” and is one of the contributing editors to “Resources for Crisis Management in Zoos and Other Animal Care Facilities.” In addition to her written works, she holds numerous certifications in the animal disaster field from groups such as the Federal Emergency Management Agency (FEMA) and the Humane Society of the United States (HSUS).

“In any disaster, people should keep close tabs on their animals. They shouldn’t be left outdoors in these type of conditions and pets need to be monitored. If a situation is unsafe for humans it is unsafe for animals.”

Guerrero continued. “Alternate flood plans should include escape areas for animals so they have access to higher elevations. Animals are not usually allowed in human emergency shelters due to health precautions and limited space. So plug into an animal network through your local shelters and community rescue groups. If you are not sure what these are ask community leaders and the animal agencies in your area for direction.”

In her experience, flood animal rescuers find critters hoarse from crying for help. She stressed that people in flood prone areas need to take precautions–and those plans should include include animal evacuation and safety.

“When people evacuate they need to take their animals because they usually won’t have a second chance to go back to get them. Contingency plans for when they are away from home are essential, too.”

Guerrero’s animal disaster booklet, now in the seventh edition, offers tips to prepare prior to a disaster, how to form or get involved in a animal disaster preparedness network, and what items to include in kits for dogs, cats, horses, and birds. Guerrero also includes tip sheets for behavior, identification, health, diet, and sanitation for multiple species during a disaster.

The booklet ends with a section on post disaster animal behavior and list valuable resources for the pet owner including animal disaster agencies, where to get training, and suppliers of kits and equipment.

Guerrero’s pet flood safety suggestions are:

-Take your animals with you! Pets that are released or left behind often become victims of flood waters, contaminated food or water, or exposure to the elements.

-Make sure animals have waterproof ID tags on them.

-Three weeks of supplies is not excessive for humans or pets.

-Proof of current vaccinations will be required for housing animals in many rescue facilities. Make sure you have copies stored in a waterproof container with other supplies so you don’t forget to take them.

-Maintain current photos of your property and animals.

-Place pet rescue decals on a window or door to alert rescue personnel to the presence of critters.

-Make sure you have a plan that is effective during the times when you are separated from your pets.

-Do not tether or restrain animals when floods waters threaten your area.

-Check for evacuation plans at your stable or form a network with other facilities.

-Storm surges and flood threats mean that you need to provide a way for critters to escape and climb to safety. This does not mean turning them loose! Make sure livestock have access to higher ground.

-Use wire crates to transport and house smaller animals since they provide better ventilation and fold up easily for storage and transport.

-Don’t create a hazard by trying to forge through flooded streets with moving water.

-Return home only after authorities advise that it is safe to return.

-Use caution when returning home and walking on higher ground since insects, snakes, and other animals may have found refuge there.

-Stressed animals often avoid food and exhibit other behavior abnormalities. Allow them to adjust and refrain from reinforcing abnormal behavior.

-Post flood threats include mosquitos and other vectors. Check with local veterinarians for preventative medical tips.

The 2006 BMW M6: BMW Performance Parts, Aftermarket Parts now available at Parts Train

(PRWEB) June 22, 2005

The all-new M6 features weight-saving technologies such as a carbon-fiber roof and 19-inch forged aluminum wheels that are almost four pounds lighter than regular cast wheels. With almost 500 horsepower available, BMW claims the M6 will hit 60 mph in under 4.6 seconds, and it will run to 20 5mph without the traditional 155-mph speed limiter. The suspension, though similar to that of the M5, is specially tuned to take advantage of the M6′s shorter wheelbase and lower center of gravity. Massive cross-drilled brakes enable the M6 to pull up from 60 mph in less than 118 feet.

It is the most powerful 6 Series yet to be produced as it shares its power unit with the recently released M5. Acceleration is from 0-100 km/h comes in 4.6 seconds and the M6 reaches 200 km/h about 14 seconds. Top speed is limited to 250 km/h. It has a 5-litre V10 engine with a power output of 373 kW at 7 750 r/min, while torque is 520 Nm at 6 100 r/min. In city driving where not much power is needed, the BMW M6 automatically sets off in its comfort-oriented P400 performance program with 296 kW (400 bhp) engine output. The V10 power unit requires roughly twice as much cooling air as the V8 in the BMW 645Ci. The V10 is indeed the most demanding engine in technical terms. BMW
