Wind Turbines On High Voltage Power Line Towers Wins NextGen Contest

ByGroovy Green May 19, 2009

I’m sure many environmentalists have passed power line towers while cruising in vehicles and wondered aloud, “Why can’t we just throw some wind turbines up there?” In fact, earlier last year, Ericsson unveiled the first-ever cell phone tower with a vertical-axis wind turbine integrated. If we can do it in cell phone towers, why not transmission towers?

That’s the question two architects and an engineer from France used as the starting point for their “Wind-It” concept — a a design to place wind turbines inside existing high-voltage electricity pylons. They’re also the winners of the 2009 Metropolis Magazine Next Generation Prize Challenge: “FIX OUR ENERGY ADDICTION.” $10K was given to the team to take their idea to the next level.

The Largest Wind Turbine Propeller We’ve Ever Seen Is 6MW Of Enormity

ByGroovy Green Apr 23, 2009

Remember that picture we had a few months back of a helicopter taking off of an enormous wind turbine? Yea, that 3.6MW behemoth today looks normal compared to this 6MW monster being installed in Germany. Apparently, it’s one of the two currently going up in the city of Hamburg. Huge — just huge.

The Green Picture: Glowing Array Of Fluorescent Bulbs Powered By Ambient Electricity

ByGroovy Green Apr 10, 2009

You know those electric fields from power lines that some people are always complaining about? Turn out they may have something be worried about. At least, that’s what I can surmise after viewing these photos of an art project on an English farm. The installation is called FIELD and creator Richard Box came up with the idea after hearing about a colleague playing light sabergames with a fluorescent tube beneath power lines in his backyard. So, he bribed a local farmer to let him take a crack at installing 1301 fluorescent bulbs underneath his power lines and “voila” — instant ambient energy. The UK Guardian explains a bit more:

A fluorescent tube glows when an electrical voltage is set up across it. The electric field set up inside the tube excites atoms of mercury gas, making them emit ultraviolet light. This invisible light strikes the phosphor coating on the glass tube, mak ing it glow. Because powerlines are typically 400,000volts, and Earth is at an electrical potential of zero volts, pylons create electric fields between the cables they carry and the ground. Box denies that he aimed to draw attention to the potential dangers of powerlines. “For me, it was just the amazement of taking something that’s invisible and making it visible,” he says. “When it worked, I thought: ‘This is amazing.’”

My home is right under some power lines. Needless to say, I’m moving.

The Jellyfish: A 36” Personal Wind Turbine For The Masses

ByGroovy Green Mar 16, 2009

Imagine a personal wind turbine that can power a home filled with LED lights — and also only cost $400. Such is the idea behind the Jellyfish — a 36” tall vertical-axis turbine that is a semi-finalist in Google’s 10 to the 100th contest–$10 million for the 5 ideas that helps the most people.

The inventor, Chad Maglaque, figures the total cost of the turbine could be brought down to only $199 — if subsidized with tax rebates. His current version, which he believes is only 12-to-18-months away from stores, is Wi-Fi and WiMax equipped and outputs 40 kWh a month. That’s not enough to take your home off-grid, but it would offset a percentage of energy consumption from other, not-so-green sources. Here’s a bit more detail from the website:

Wind Turbine Attacked By UFO, Investigation Underway

ByGroovy Green Jan 8, 2009

Could it be that the alien invasion promised in the film The Day The Earth Stood Still is underway? In the flick, if humans didn’t clean up their act with regards to the planet, a can of whoop-ass was going to be opened on them. According to some locals living in Lincolnshire, UK, such world ending promises are being carried out — on wind turbines of all things. From the article,

An investigation was under way today into how a 65ft blade was mysteriously torn off a wind turbine amid reports of “strange lights” in the sky. The 300ft turbine at Conisholme in Lincolnshire was left wrecked after the incident. The Sun quoted residents speculating that the damage could have been caused by a UFO. The Sun said flashing orange-yellow spheres had been seen by dozens of people in the area, including by Dorothy Willows, who lives half a mile from the scene of the incident. Ms Willows was in her car when she saw the lights. “She said: “The lights were moving across the sky towards the wind farm. Then I saw a low flying object. It was skimming across the sky towards the turbines.” The blade was ripped off hours later, at 4am.

Ever Wonder How Large Those Super-Big Wind Turbines Are?

ByGroovy Green Jan 6, 2009

Just one look at the above photo gives you a sense of just how large a 3.6MW wind turbine really is. The image comes to us from Eurocopter — who were just contracted to be used exclusively for wind farm maintenance in the UK. Apparently, these 3.6MW monsters are so tall that it’s a bit quicker to get up there via helicopter and make emergency repairs than to try and scale ‘em through the internal ladder system.

Called the “Greater Gabbard wind farm” near the East Anglia coast — the 140 turbines will be located 20 miles from land in the North Sea. When completed in 2010, it will be the largest wind farm in the world.

Vampire Killer: Good for You Good for the Planet

ByGroovy Green Dec 3, 2008

Vampire power is a big problem, even though you hit power off on that remote it doesn’t mean your television isn’t still sucking energy from the grid. Electronic appliances in standby mode can add up to 10% of your electric bill.

Good for You, Good for the Planet, a company based in Madrid, Spain, has developed a product to bring an end to the wasted electricity of standby mode. When the user desires to power the system up again it will power it up again without having to send the appliance through its start-up sequence again.

NH Hoteles SA of Spain has been testing a prototype of Mr. García’s gadget at some of the chain’s 350 hotels in 22 countries. It hopes to install the device in its 50,000 rooms as part of a drive to cut energy use by 20% by 2012.

“We’re very interested in this product and are seeing how we can implement it in the short or medium term,” says Luis Ortega, the chain’s director of environment and engineering. “That small saving, multiplied by 24 hours, 365 days a year, makes quite a big difference — especially when you’re talking about 50,000 television sets.”

Until technology like this becomes mainstream, you can kill vampire power in your home or office simply by unplugging or switching off your plug-strips.

Another Homeowners Association Slams Attempt To Go Solar

ByGroovy Green Oct 21, 2008

Homeowners Associations have got to be one of the more inane aspects of American society. A friend of mine moved into a neighborhood with one, completely unprepared for the mess she was getting into. Now, no toys can be left outside, all cars must be kept in the garage at all times, the grass must be a certain height and color, and every change to the home must first be approved by a “board”. It’s both a hilarious and sad way that some choose to live — all for the sake of homogeneity in aesthetics.

In March of 2007, we reported on an incident where the town of Scarsdale denied a family the opportunity to put up solar panels — on the basis that they were ugly and “not in keeping with the character of the community”. It was BS then — and it’s still BS. Now, another homeowners association in California is denying one man’s quest to reduce his electric bill by installing solar panels on his roof. Their reason? They do not believe the technology fits in with their rules and guidelines of a community with “restrained elegance.”

New Cruise Ship Designed With Solar, Efficiency In Mind

ByGroovy Green Sep 26, 2008

A new ship from Celebrity Cruises, currently about 80% complete, is being built with eco-friendly technology and design in ever phase of construction. Personally, I find cruises to be one of the most wasteful and benign ways to travel — but they’re not going away, and this development is welcome.

The company actually designed the hull of the ship first — a radical departure from conventional cruise ship construction where things are generally created “top down,” with passenger space configured first, then the hull constructed to fit that space. As a result, the hull is one of the most fuel-efficient possible and the rest of the ship was configured to work around it.

There will also be 80 solar panels on board to power small things such as elevators. The company acknowledges that solar is not currently a cost-effective addition, but add that as prices decrease, the infrastructure will be in place on board to carry more photovoltaics. The hope is that over time, the ship will utilize more clean energy in its consumption.
