Solar Wind Energy Tower has been awarded an allowance of Patent Application Number 13/098,476, titled "Atmospheric Energy Extraction Devices and Methods", by the United States Patent and Trademark Office.

The patent covers a structure for producing electricity, specifically a tower capable of adding moisture at the top of the structure to hot-dry air so as to generate a downdraft of wind within the interior of the Tower, vanes coupled to the exterior of the Tower that at least partially define a plurality of elongated pockets at the exterior of the Tower, flaps located within the pockets configured to redirect incident wind downwards, and at least a first wind tunnel configured to receive the redirected wind so as to convert such wind to electricity.

Ronald W. Pickett, President, Chief Executive Officer of SWET, stated, "We are pleased to have received notice that our patent application for the Tower structure design has been allowed, and that a patent will be issued shortly.

The patent application incorporates the entire core Tower structure, including the injection of moisture as a catalyst to generate the downdraft wind, and the additional exterior dual wind capture vanes.

In the future, as we expand our geographic footprint, the dual wind technology will provide us with the ability to construct our power plant in locations with potentially more variable weather conditions, since we can now incorporate the power created by the ambient wind captured along the outer surface of the Tower structure with the power generated internally.

This external wind capture boosts the overall power output. This patent allowance, along with our previously issued patent titled 'Efficient Energy Conversion Devices and Methods', encompasses our overall basic system architecture.

"We intend to continue to protect our technology as we develop enhancements to it. Our business plan has always been to efficiently extract the maximum energy generated by the captured wind, with the least loss of power while compensating for the normal differentials in atmospheric conditions."

Top 50 Solar Energy Stories Of The Year (Part One: #1-10)

Print Friendly

We’re trying to get more solar energy stories going over on Planetsave. To catch readers up, I’m doing a short series on the top 50 solar energy stories of 2013 so far. I guess that’s 10 per month, theoretically. Learning from the Top 33 EV Stories article I recently published, I’m splitting this one into 5 posts. Otherwise, the page would take forever to load. Plus, it’s easier to swallow 10 at a time.

It’s pretty hard to actually rank these top 50 articles, so I didn’t even try. The list is in no particular order. The numbers are basically just for referring people (your friends, family, coworkers, etc) to specific stories you think are worth highlighting. Don’t forget to do that! Once the posts are up, I will add links here:

OK, here are the first 10:

1. World’s Largest Solar Power Plant Is Now Under Construction
Antelope Valley solar

MidAmerican Solar and SunPower Corp. in April marked the start of construction on the 579 megawatt Antelope Valley Solar Projects (4 months after MidAmerican bought the project). The solar power plant (aka solar farm) is expected to be the largest in the world when completed.

Extra Notes:

2. New Electricity Capacity On The California Grid Is Set To Be Almost 100% Solar In The 2nd Half Of 2013

Solar is growing fast, especially in California, where sunshine and healthy incentives make it competitive. Plus, utilities there have renewable energy mandates they have to hit. The stars have lined up for a fun second half of 2013, with nearly all new electricity capacity in the state scheduled to be from solar power systems.

3. So Many Solar Efficiency Records Set

Let’s just run down them:

4. Solar Grid Parity Now In Over 100 Countries

solar-grid-parity-map

This definition of “grid parity” is the cost of rooftop solar versus the cost of electricity sourced from the grid – this is sometimes known as “socket parity.” At least one source finds that 102 countries have now hit grid parity.


5. Solar Likely To Be #2 Source Of New Power Capacity In US In 2013

solar growth us

In an on-air Google Hangout in March, Recurrent Energy CEO and Solar Energy Industry Association (SEIA) Chairman Arno Harris noted that more solar power capacity is projected to be installed in 2013 than from any electricity source other than natural gas. And, by 2016, solar energy may actually be the #1 source of new power for at least one year.

6. World’s Largest Single-Unit Concentrated Solar Power (CSP) Plant Launched

The world’s largest single-unit concentrated solar power (CSP) plant launched in Abu Dhabi, UAE in March. The Shams 1 “will power thousands of homes in the United Arab Emirates and displace approximately 175,000 tons of COâ‚‚ per year.” I was quite lucky to visit the solar power plant in January and learn much more about it.

7. Hawaii At Grid Parity

hawaii-solar-infographic

Hawaii has hit “solar grid parity.” In other words, you’re better off going solar than paying for conventional electricity from the power grid. Above is a fun infographic about that and related matters, which actually shows that residents there &ldquoay off” their solar power investments within 3–5 years, and then have free electricity for decades. Nice. (By the way, utility-scale solar has actually hit grid parity in cloudy Oregon, too!)

8. Grid Energy Storage Projects Starting To Take Off; Promising Energy Storage Companies Budding

energy-storage-market-potential

Grid energy storage is not very important for renewable energy growth at this point in time. However, when renewable energy accounts for a large percentage of our power supply, it will be quite important. So, it’s good to see that significant and competitive projects are starting to get off the ground. Here are a few hot stories along those lines:

9. Solar Equaled 100% Of New US Power Capacity In March

new power capacity solar us 2013

The Federal Energy Regulatory Commission’s Office of Energy Projects in April released a report, “Energy Infrastructure Update,” that showed that renewable energy sources (biomass, geothermal, solar, water, wind) accounted for 82% of all new domestic electrical generating capacity installed in the first quarter of 2013. Furthermore, solar power accounted for all new power capacity in March. (Note: this doesn’t even include residential or commercial solar power systems.)

10. Africa’s Largest Solar Power Plant Launched

KDC Solar and North Jersey Media Group Cut Ribbon on Large Solar Facility
by Staff Writers
Bedminster NJ (SPX) May 10, 2013


The solar operation will cover more than 60 percent of the power needs at North Jersey Media Group's printing plant.

KDC Solar LLC, headquartered in Bedminster, New Jersey, through its wholly owned subsidiary, KDC Solar NJMG, has commenced commercial operations at North Jersey Media Group's (NJMG) printing facility in Rockaway, New Jersey.

The solar project is the largest PV solar system (4.96 megawatts) at any printing facility in the State of New Jersey. The new system, which will generate approximately 6.2 million kilowatt hours of solar electricity per year, will allow North Jersey Media Group's facility to receive approximately 60% of its annual electric needs from clean renewable solar energy and substantially reduce its carbon footprint.

This is the equivalent of 700 homes being supplied with all their electricity for the year. In addition, there are discussions underway to add additional solar capacity when a new roof is installed on a portion of the facility.

A ribbon cutting ceremony marking the commencement of commercial operations was held at NJMG's facility on May 6th. Among the local dignitaries in attendance were Don Reddin, Rockaway Township Council Member, Dave Washington, Rockaway Township Council Member, Gregory Poff, Rockaway Township Business Administrator, Vincent Brennan, Rockaway Township Police Captain and Planning Board Member, Jim Lutz, Rockaway Township Engineer and Craig Babcock, Rockaway Fire Marshall.

KDC Solar signed an engineering and construction contract for the installation of the facility with Samsung C and T. J. Fletcher Creamer and Son, a fifth-generation contractor headquartered in Hackensack, New Jersey, was the general contractor.

The solar facility uses over 20,400 photovoltaic panels, 10 SMA America 500 kilowatt inverters and is ground mounted, roof mounted and on car ports across 50 acres of land.

"North Jersey Media Group is pleased and proud to have served as the host and electric off-taker of this solar project," said Stephen Borg, President of NJMG.

"This use of clean energy helps us continue our environmental stewardship as well as reduce costs. KDC Solar is a wonderful partner and I strongly recommend them to those considering similar projects," he said.

"We are very pleased to have worked with North Jersey Media Group and, in particular, the Borg family to bring this concept to reality. This facility is the largest PV solar facility at any printing facility in the State of New Jersey and will supply clean, lower cost, long-term solar energy to North Jersey Media Group for many years," said Hal Kamine, KDC Solar's Chief Executive Officer.

"This project is another example of a successful 'behind-the-meter' clean solar electric system for business/government and institutions, which in turn create or preserve both short and long-term jobs for the state."

Dominion Virginia Power Selects Old Dominion University For First Rooftop Solar Power Installation
by Staff Writers
Norfolk VA (SPX) May 06, 2013


File image.

Dominion Virginia Power has selected Old Dominion University to be the first participant in the company's Solar Partnership Program. More than 600 solar panels will be installed this summer on the roof of ODU's Student Recreation Center in the heart of the campus and generate 132 kilowatts for the electric grid.

"This installation will pave the way for us to assess the benefits of solar facilities on our electrical distribution system," said Ken Barker, Dominion Virginia Power vice president-Customer Solutions.

"This new program is already encouraging the growth of solar energy in Virginia as many other customers have contacted us and shown interest."

The Solar Partnership Program was approved by the Virginia State Corporation Commission last November. Dominion will construct and operate up to 30 megawatts of company-owned solar facilities on leased rooftops or on the grounds of commercial businesses and public properties throughout the company's Virginia service area. Fully implemented, the program would generate enough power for 7,500 homes. Each installation could generate as much as two megawatts of electricity.

"When the program was announced last year, it was readily apparent that Old Dominion University was a perfect fit for this innovative project," said ODU President John R. Broderick.

"Our Student Recreation Center is one of the main hubs of activity on our campus and our university, as a whole, is a hub of alternative energy research. This installation is yet another example of ODU's leadership in the development of solar installations and ground-breaking solar energy research."

The 132-kilowatt solar project should generate enough power during daylight hours to supply the energy needs of approximately 35 homes. The project is expected to be completed late this summer. Energy information from the installation will be available at a lobby kiosk inside the Student Recreation Center and in Kaufman Hall, ODU's engineering school.

Asparagus Growing Guide

Rich in B vitamins, vitamin C, calcium, and iron, asparagus is one of the first crops of spring harvest.

growing asparagusAsparagus is a perennial vegetable grown for its delicious young shoots. Rich in B vitamins, vitamin C, calcium, and iron, asparagus is one of the first crops of spring harvest. Fresh-picked spears are far more tender and tasty than store-bought ones.

Asparagus thrives in any area having winter ground freezes or dry seasons. The mild, wet regions of Florida and the Gulf Coast are about the only places where it’s difficult to grow.

Planting
Select and prepare your asparagus bed with care; this crop will occupy the same spot for 20 years or more. It can tolerate some shade, but full sun produces more vigorous plants and helps minimize disease. Asparagus does best in lighter soils that warm up quickly in spring and drain well; standing water will quickly rot the roots. Prepare a planting bed about 4 feet wide by removing all perennial weeds and roots and digging in plenty of aged manure or compost.

Asparagus plants are monoecious—each individual plant is either male or female. Some varieties of asparagus, such as ‘Jersey Knight’ and ‘Jersey Giant’ produce all male or primarily male plants, so they’re more productive—male plants yield more harvestable shoots because they don’t have to invest energy in producing seeds. Choose an all-male variety if high yield is your primary goal. If you like to experiment, you may also want to grow an heirloom variety or a purple-stalked variety like ‘Purple Passion’. With an all-male variety, twenty-five plants are usually adequate for a household of four; plant double that amount for standard varieties. (Ardent asparagus lovers recommend tripling these quantities.

Starting asparagus from 1-year-old crowns gives you a year’s head start over seed-grown plants. Two-year-old crowns are usually not a bargain. They tend to suffer more from transplant shock and won’t produce any faster than 1-year-old crowns. Buy crowns from a reputable nursery that sells fresh, firm, disease-free roots. Plant them immediately if possible; otherwise, wrap them in slightly damp sphagnum moss until you are ready to plant.

Discovery Opens Door to Efficiently Storing and Reusing Renewable Energy

Mar. 28, 2013 — Two University of Calgary researchers have developed a ground-breaking way to make new affordable and efficient catalysts for converting electricity into chemical energy.

Their technology opens the door to homeowners and energy companies being able to easily store and reuse solar and wind power. Such energy is clean and renewable, but it's available only when the sun is shining or the wind is blowing.

The research by Curtis Berlinguette and Simon Trudel, both in the chemistry department in the Faculty of Science, has just been published in the journal Science.

"This breakthrough offers a relatively cheaper method of storing and reusing electricity produced by wind turbines and solar panels," says Curtis Berlinguette, associate professor of chemistry and Canada Research Chair in Energy Conversion.

"Our work represents a critical step for realizing a large-scale, clean energy economy," adds Berlinguette, who's also director of the university's Centre for Advanced Solar Materials.

Simon Trudel, assistant professor of chemistry, says their work "opens up a whole new field of how to make catalytic materials. We now have a large new arena for discovery."

The pair have patented their technology and created from their university research a spin-off company, FireWater Fuel Corp., to commercialize their electrocatalysts for use in electrolyzers.

Electrolyzer devices use catalysts to drive a chemical reaction that converts electricity into chemical energy by splitting water into hydrogen and oxygen fuels. These fuels can then be stored and re-converted to electricity for use whenever wanted.

The only byproduct from such a 'green' energy system is water, which can be recycled through the system. To store and provide renewable power to a typical house would require an electrolyzer about the size of a beer fridge, containing a few litres of water and converting hydrogen to electricity with virtually no emissions, the researchers say.

Key to their discovery is that they deviated from conventional thinking about catalysts, which typically are made from rare, expensive and toxic metals in a crystalline structure.

Instead, Berlinguette and Trudel turned to simpler production methods for catalysts. This involved using abundant metal compounds or oxides (including iron oxide or 'rust') to create mixed metal oxide catalysts having a disordered or amorphous, structure.

Laboratory tests -- reported in their Science paper -- show their new catalysts perform as well or better than expensive catalysts now on the market, yet theirs cost 1,000 times less.

Their research was supported by the university's Institute for Sustainable Energy, Environment and Economy, Alberta Innovates, Mitacs and FireWater Fuel Corp.

FireWater Fuel Corp. expects to have a commercial product in the current large-scale electrolyzer market in 2014, and a prototype electrolyzer -- using their new catalysts -- ready by 2015 for testing in a home.

Happy Easter !

They Paved Paradise and Put Up A Parking Lot 

Parking-lot owners are finding a new use for their vast expanses of pavement: solar power.

From Long Island to the Arizona desert, developers are covering their lots with canopies of solar panels. Lot owners get to double up on their use of underutilized land and to offset their utility bills at the same time. And very little stands between most lots and the sun, so they can produce plenty of power. What's more, the canopies provide shade when it's hot and prevent snow from accumulating in the winter. Some have charging stations for electric vehicles.

NRG Energy Inc., NRG +0.95% Princeton, N.J., installed and owns the panels, leasing the site and selling power. The company and the team both declined to disclose financial details about the project.


The solar parking-lot system meets 20% of FedExField's power needs on game days.

One of the country's largest solar carports is now under construction at Rutgers University's Livingston Campus in Piscataway, N.J. The eight-megawatt installation will cover about 32 acres and will cost about $40.8 million before federal and state incentives. The project is being built by a private company, which will lease the panels to the university. Rutgers expects to save $28 million in electricity costs over 20 years.
