Assemble your own solar panel

Tuesday, February 9th, 2010

Since there’s almost any size and shape of solar panel available for purchase from a myriad of vendors across the Internet why would anybody want to go through the hassle of tabbing together their own cells to build a solar panel? Because you can, obviously. This DIY video will run through the basics of chaining together polycrystalline cells and leaves the details like enclosure and such to the user.

The Next Revolution: Iran Gets its First Electric Car

Sunday, September 13th, 2009

Outside of Israel and Shai Agassi’s electric vehicle (EV) infrastructure company Better Place, the Middle East doesn’t have much of an electric car industry. That might change soon now that a team of Iranian scientists from Tehran’s Khaje Nasir Toosi University of Technology have developed the country’s first EV, a mini two-seater called “Qasedak-e Nasir”, or the dandelion of Nasir.

Water Droplet Resort Will Convert Air into Purified Water

Sunday, September 13th, 2009

Architecturally and thematically designed in the shape of a drop of water, the Water Building Resort intends to become the first building ever to convert air into water with the help of solar power. What sounds like magic will be achieved with the following combination of nature and technology: A sunny, southerly facing facade made of photovoltaic glass will harness solar energy, allowing light to pass through. The northern facade features a latticed design for ventilation as well as unprecedented Teex Micron equipment that will convert humid air and condensation into pure drinking water.

Designed for construction in warm and humid coasts, the Water Building Resort, a resort complex, will also house a water treatment facility in the bottom floor, for purifying salty sea and rain water, along with a center of technological investigation to control and certify water quality. Restaurants, gyms, exhibition halls, hotel and conference rooms, and spa services will fill the upper floors – all based on the theme of water, the environment and renewable energy. An underwater aquarium will sit at the base of the Water Building Resort, rounding out the water conscious theme and practices.

Nissan Turns Over An Electric Leaf

Sunday, August 2nd, 2009

After teasing us for months with prototypes and promises, Nissan unveiled a sleek five-passenger electric hatchback with a claimed range of 100 miles. It’s called the Leaf, and Nissan says it will be here next year.

Nissan pulled the sheet off the Leaf tonight at the company’s new headquarters in Yokohama, Japan, where CEO Carlos Ghosn promised to usher in the auto industry’s electric era. All of the major automakers are rushing to bring mainstream EVs to market in the next few years, but Japan’s No. 3 automaker has been among the most aggressive. Ghosn has made it clear he believes EVs are the future and he wants Nissan to lead the way

“We have been working tirelessly to make this day a reality — the unveiling of a real-world car that has zero, not simply reduced, emissions,” Ghosn said in a statement. “It’s the first step in what is sure to be an exciting journey – for people all over the world, for Nissan and for the industry.”

Nissan isn’t saying what the Leaf will cost — look for a price in the $25,000 to $30,000 range — but promises it will be the first affordable, practical electric car when it goes on sale in the U.S., Japan and Europe by the end of 2010.

First Solar breaks solar energys $1 per watt barrier

Sunday, March 1st, 2009

This is great news…soon it will be possible to have solar powered nodes at a low cost. As a comparison point, solar panels cost about $7/watt in 2002…hmm…wonder if this has anything to do with the 2 gigs of RAM I bought for $20…

First Solar Inc this week claimed a milestone in the solar industry toward providing a sustainable and affordable solar energy solution: solar modules manufactured below the $1 per watt point, at a cost of $0.98 per watt.

“This was truly a worldwide goal,” said Ken Zweibel, director of the Institute for the Analysis of Solar Energy at George Washington University. “The solar industry has been aiming at this goal for the past 25 years, and now it has been met by First Solar. The US leads the world in photovoltaics in terms of the technology with First Solar being the lowest cost practical manufacturing modules below $0.98 per watt and SunPower reporting the highest solar converting efficiency of approximately 20%.”

San Jose-based SunPower last May touted full-scale solar cell protototypes at 23.4% efficiency. The company has reported improvements in mass production since its first all-back contact solar cell prototype in 2003. CEO Tom Werner has stated that SunPower’s Gen 2 technology in mass production since 2007 is 22% efficient.

Got Manure? These Trucks Run on It

Sunday, March 1st, 2009

A California dairy has converted a pair of 18-wheelers to run on biomethane produced from cow manure, creating what is believed to be the nation’s first cow-pie–powered trucks.

Hilarides Dairy will use manure produced by 10,000 cows to generate 226,000 cubic feet of biomethane daily — enough to reduce the Central Valley farm’s diesel fuel consumption by 650 gallons a day.

“For us it made sense to invest in this technology. Now we can utilize the dairy’s potential to power our trucks in addition to generating electricity for our operations,” Rob Hilarides (pictured above), owner of the dairy, said. “This will significantly reduce our energy costs and give us some protection from volatile energy prices.”

Not to mention something to do with all that manure.

Nation’s First ‘Underwater Wind Turbine’ Installed in Old Man River

Tuesday, December 23rd, 2008

The nation’s first commercial hydrokinetic turbine, which harnesses the power from moving water without the construction of a dam, has splashed into the waters of the Mississippi River near Hastings, Minnesota.

The 35-kilowatt turbine is positioned downstream from an existing hydroelectric-plant dam and — together with another turbine to be installed soon — will increase the capacity of the plant by more than 5 percent. The numbers aren’t big, but the rig’s installation could be the start of an important trend in green energy.

And that could mean more of these “wind turbines for the water” will be generating clean energy soon. (more…)

Solar Hybrid Yacht Shows Electricty and Water Do Mix

Who says water and electricity don’t mix? The world’s first solar-electric-diesel hybrid yacht will have you impressing the greenies at the Yacht Club and sailing the seas in style.

The Island Pilot DSe Hybrid catches rays with a 6.8 kW solar array that’ll get you to Margaritaville and back at 6 knots with zero emissions. But if the sun ain’t shining in Cocomo, you can crank up the Steyer Motors parallel hybrid system that mates a 75-horsepower diesel engine and a pair of 36-horsepower electric motors powered by a 20-kilowatt-hour battery pack.

The 40-footer was a hit at the recent Fort Lauderdale International Boat Show, where it was one of several green vessels and gadgets that ranged from the Epower Marine Calypso Classic electric fishing boat to the 100 percent recyclable propellers made by Piranha Propeller.

But it was the $600,000 DSe that really wowed the crowd.

The DSe can run for as long as two hours on battery power. Kick on the diesels and she’ll cruise at 13 knots while charging the battery pack through a pair of 25-kW generators. Run the diesel engine and electric motor in tandem and she’ll hit 15 knots. (more…)

In this season of specters and spooks, what could be scarier than a steel-winged robotic spy plane shaped like a bat? The aptly named COM-BATis a six-inch surveillance device that is powered by solar, wind, and vibrations. The concept was conceived by the US military as a means to gather real-time data for soldiers, and the Army has awarded the University of Michigan College of Engineering a five year $10-million dollar grant to develop it.
