Rosalie Bay Resort Features Dominica’s First Wind Turbine
Resorts around the world continue to impress me with their commitment to sustainable practices — but Rosalie Bay Resort on the island of Dominica in the Caribbean is truly a standout.
Five years in the making, the 22-acre getaway was built on principles of conservation and preservation, surrounded by an undisturbed natural setting of mountains, lush forests, and gardens. In addition to solar panels, the resort also features a Norwin Turbine 225 kW — which provides some 70% of the power used by the 28 beautiful rooms in nine cottages. With these renewables in place, Rosalie is effectively self-sustaining; an epic achievement that’s yet still rare in today’s world of “green resorts”.
“Nature should be preserved and shared,” said Dr. Ken Watson, general manager. “Rosalie Bay Resort was designed to be environmentally sustainable while showcasing one of the most beautiful natural settings in the Caribbean. Many resorts claim to be green, but we’ve made a legitimate commitment with the wind turbine being the centerpiece of our pledge.”
My review of the NREL Western Wind and Solar Integration Study
The NREL/GE Energy WWSIS study appears to be built on several questionable assumptions, each allowing the modeled system (of up to 30% wind/5% solar in the West Connect within the great Western Interconnect) to withstand the inherent difficulties of large scale renewable integration. The primary issue, consistent with my dissertation research, is that the authors assume that we can afford to massively overbuild the capacity of the system, adding the large percentages of renewable generation on top of newly built and existing plants. This allows one to be able to ignore the hourly or sub-hourly periods with extremely low output from renewables, as well as the days or weeks at a time during the summer when wind production is well below yearly average output levels. An ample reserve is at the ready to step in when renewables perform poorly. Secondly and equally important, the authors assume that coal plants, which have traditionally run in a base load capacity, will be able to be operated very flexibly – on par with combined cycle gas plants.

World’s Largest Wind Turbine To Float Off Norway
We’ve seen mega-turbines before — but never one with an output of 10MW, and certainly not one that floats!
When completed, the world’s largest turbine will stand at roughly 533 feet with a rotor diameter of 475 feet. At three times more powerful than current turbines, it will be able to power over 2,000 homes. From Treehugger,
It will be built by the Norwegian company Sway and tested first on land in Oeygarden, southwestern Norway. Unlike most offshore wind projects where turbines rest on the seafloor, Sway turbines float. This means further offshore development where winds are stronger and more consistent.
The floating tower is a pole filled with ballast beneath the water creating low center of gravity. Anchored to the seabed with a single pipe and a suction anchor, it can tilt 5-8°, and turn around with the wind.
It’s expected that the prototype will cost close to $70 million and be completed sometime in 2011.
Renewable Energy Company Creating The Biggest Green Party You’ve Ever Seen
We love raucous festivals like Burning Man and music jamborees like Bonaroo, but we’ve never heard of one that combines the spirit of these events with the mission to actually accomplish something. Like building a build a micro wind turbine farm.
Such is the idea behind “Villages in the Sky: DIY World Change” — a a family-friendly renewable energy and sustainability celebration located in the Ozarks and scheduled for June 2010. Unlike gatherings that strive to leave things the way they were before anyone arrived, Villages in the Sky is looking to take advantage of crowd sourcing to create a better place than existed before. Participants will help build a micro wind turbine farm and bio-mass systems as well as giant play structures (zip lines, tree houses, ropes courses, etc). The entire event is internally cash free event which promotes a volunteer ethic and strangers working cooperatively for a shared goal. In fact, the main goal is to leave behind the beginnings of a locally self sufficient eco-village. Perhaps even one inspired by the Ewoks. From the website,
Buying An Electric Car? You Might Want To Order Your Charging Station Now
2010 will most likely go down as the year electric cars were (once again) made available to the public through Big Auto. Both Nissan and Chevy have plans to release the Leaf and Volt respectively — and both focus on getting energy from being plugged in. (Although the Volt can charge its battery utilizing its small “range-extender engine”, but then what’s the point of having an electric car?)
If you’ve got the deep pockets for one, the most conventional way of charging the vehicle will be to simply plug it into an ordinary wall socket. Charging a Nissan Leaf would take up to 16 hours, and charging a Volt would take eight. If you’re in a hurry, however, the best thing to have on-hand in the garage is a “quick charger” — which pushes a much more considerable amount of juice to your car. Instead of 8 hours, you can now have a fully charged Volt in under 2.5 hours.
Unfortunately, having a quick charger installed in your garage is not something just anyone can do.
Solar-Powered Sleeve Coming To iPhone, Blackberry, Other Mobile Handhelds
We’ve seen plenty of solar-charger accessories for mobile phones and other gadgets, but this is the first one that appears to attach seamlessly. Created by product design firm MotionTouch for a company called Powcell, this solar-powered sleeve slides onto the back of a mobile phone handset and uses light to charge the unit.
The large solar panel provides the greatest surface area for light-capture and maximises the sleeve’s efficiency, including working in some ambient light conditions. And Powcell continues to charge its internal battery even when removed from the phone – so when reconnected it provides talk-time even if the device battery is exhausted.
Ahead of full production the sleeve has attracted considerable interest from major phone manufacturers, which have even approached Powcell about sleeves for future, yet-to-launch models of their phones.
IZIP Trekking Enlightened Hybrid-Electric Bike: First Impressions
If you’ve ever lived in or visited Ithaca, NY your probably familiar with the phrase “Ithaca is gorges”. It’s a funny little saying that gives a good indication of the region’s topography — hills, hills, and steeper hills. In fact, the inclines we have around here would make even Lance Armstrong break a sweat. So, it was with great expectation that I took advantage of an opportunity to review the IZIP Trekking Enlightened hybrid-electric bicycle from Currie Technologies. Could it be possible to bike to work and not immediately have to take another shower?
I’m still figuring that out — and will have a full review shortly — but so far, I have to say that I’m very impressed with the technology being utilized in this bike. First off, this isn’t one of those bikes that you hit a switch and kick back while the electric motors putts you along. The IZIP instead is an electric-assist — giving you some extra torque to help you up some tough inclines. To that end, you still have to pedal. The beauty of this system is that you can choose to have it on or off — or at different levels of assist. About to hit a hill and want some support? Simply press the “+” button on the left handlebar and watch the LCD indicator light a few bars higher. Want to back off? Hit the “-” button. It’s as simple as that — and believe me, you still get a workout.
Enjoy A Private Solar Shower In This Personal Pop-Up Tent
Enjoy solar showers, but really want to be completely naked in the process? Unless you’re in a nudist colony, that option might be not available on a public beach. However, this innovative (and stylish) pop-up privacy tent from Guide Gear will hide your bits and bops while giving you a clean, hot rinse. The 6.5 lb tent is quick to setup and includes a 5-gallon PVC Solar Shower. Said one recent reviewer:
Our family has always been more on the “minimal” side for car camping trips, but with my 23 year old daughter and her friends along on our recent trip, we needed a shower. We bought a Zodi water heater and this pop up shower tent. Great decision! The tent pops up in a second, nothing to put together and added almost no weight or bulk to our gear. The olive green material provided total coverage, blended nicely with the outdoor terrain, and had plenty of room for big guys. The 3 adjustments we made were adding a clip/clothespin to attach the shower head to the top, a chair right outside to hang towel and clothes (it cannot support much weight), and a large plastic pan to stand on. With those items, we had eight of us showering daily with no hitch.
That being said, you could also just go and jump in the nearest river. While this item is indeed handy, it may just be another piece of “baggage” that’s rather unnecessary when camping. To each their own, however — you be the judge.
Wind Turbines On High Voltage Power Line Towers Wins NextGen Contest
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. From the article,
The Largest Wind Turbine Propeller We’ve Ever Seen Is 6MW Of Enormity
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
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
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
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?
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
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
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
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.
