Scotland will build a massive battery to store excess wind power
UK energy supplier Scottish Power plans to launch a massive battery-storage system to capture renewable power from its 214 wind turbines. The 50 megawatt lithium-ion battery will allow Scottish Power to store energy when wind speeds are high and release it when they're low. According to The Guardian, this is the UK's most ambitious energy storage project to-date, and it will take the UK one step closer to reaching a net zero carbon economy.
Inhabitat's Week in Green: self-sustaining homes, wooden wind turbines and the world's first solar-powered nation
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. The planet is in rough shape. A new report from the Renewable Energy Industry Institute found that total levels of global greenhouse gas emissions reached a record high last year. And we're starting to feel the consequences of all that carbon output as climate change leads to freakish superstorms like Hurricane Sandy. As New York City prepares for more large, destructive storms, many urban planners have raised the possibility of installing giant Rotterdam-style floodgates to protect the city. There are no current plans to install floodgates around NYC, but given the increasingly unpredictable weather in the region, it might be a good idea. In a different answer to rising sea levels, Dutch studio Whim Architects produced plans for floating, self-sustaining homes made from plastic waste from the Great Pacific Garbage Patch. Scientists also found that climate change is actually affecting satellites that are orbiting the planet, and a separate study warned that climate change could wipe out coffee production by 2080.
Study says wind turbines raise surrounding area temperature, but only at night
Who said the butterfly effect couldn't apply to renewable energy? Though wind farms are considered pretty green on the energy-generating spectrum, it looks like they, too, have an impact on the planet. According to a study published today in the journal Nature Climate Change, turbines can raise the local temperature -- albeit slightly. From 2003 to 2011, researchers monitored satellite data for west-central Texas, which is home to 2,350-plus turbines and four of the world's largest wind farms. In that decade, scientists observed a temperature increase of 0.72 degrees in wind farm regions compared to areas without turbines. That warming trend was especially marked at night, when the temperature difference between the ground and the air is highest. The temperature increase was also higher in winter; researchers say that these cooler, windier conditions cause turbines to generate more electricity and therefore create more heat. Since the study didn't find any change in daytime temperatures, it looks like we don't have to ring the global warming alarm just yet.
Solar Wind bridge concept could power 15,000 homes, grow vegetables
Why just use solar power or wind power when you can use both? Designed by Francesco Colarossi, Giovanna Saracino and Luisa Saracino as part of an Italian design contest to re-imagine a decommissioned bridge (for which it placed second), this so-called Solar Wind concept would have solar cells embedded in the roadway (an idea that's already catching on) and an array of 26 wind turbines underneath, which the designers say could produce enough energy combined to power 15,000 homes. To make the design greener still, the designers have even included a "green promenade" that would run alongside the road, which they suggest could be used to grow fruits and vegetables that'd then be sold to folks driving by. Incidentally, while it's less focused on technology, the design that placed first in the contest (a so-called "vertical village") is pretty impressive in its own right -- check it out after the break.
Philadelphia Eagles going self-sufficient on stadium energy from 2011, 30 percent of it renewable
Let's skip right past the cringe-worthy "Declaration of Energy Independence" slogan and look at what the Eagles are actually doing with their pro sports venue. The franchise that dresses in midnight green is aiming to smarten up its eco-green credentials with a new partnership with SolarBlue that will provide all of the Eagles' stadium energy needs for the next 20 years, after which point the team will be free to resell any surplus electricity back to the grid. 15 percent of the total output with be generated with spiral wind turbines erected around the top rim of Lincoln Financial Field, another 15 will come from 2,500 solar panels to be installed near the stadium, and the rest will be obtained from a biodiesel / natural gas plant. So it's not all renewable, but a nice step in the right direction, nonetheless.
Inhabitat's Week in Green: high speed rail, augmented reality, and body broadband
The Week in Green is a new item from our friends at Inhabitat, recapping the week's most interesting green developments and clean tech news for us. It was a monumental week for efficient transportation as China unveiled plans to connect its high speed rail network all the way to Europe. We were also excited to see Solar Roadways unveil the first prototype of an energy-generating road that stands to transform our freeways into power conduits. Meanwhile, one 74 year old man is going solo and blazing his own trail across the states aboard a solar powered stroller. Inhabitat also showcased several amazing feats of architecture this week. One of the world's first skyscrapers with built-in wind turbines is rising above London, while designer Enrico Dini has created a gigantic 3D printer that is able to create entire buildings out of stone. Finally, we explored all sorts of ways that people are getting wired - literally. Students at the University of Washington are working on a set of solar-powered augmented reality contact lenses that may just bring terminator vision to the masses, while Spanish scientists are working on nanochips that can be that can be implanted into human body cells to detect diseases earlier. And in case you haven't heard, "me-fi" is the new WiFi as researches have discovered a way to transmit 10mbps broadband data through a human arm.
Inhabitat's Week in Green: turbines, rubber circuits, and cola-powered cars
We're happy to introduce The Week in Green, a new item from our friends at Inhabitat. Each week they'll recap the week's most interesting green developments and clean tech news for us. Welcome! Sure, the iPad happened this week, but we also caught sight of several hot green gadgets and clean tech innovations this week that stand to shape the future of green consumer technology. First off, design star Philippe Starck brought haute design to clean tech with two novel designs for home wind turbines. Starck's high-profile products have made him a household name, so we're interested to see if his latest creations kick off a trend towards "designer" wind power. We were also impressed by researchers at Princeton University who recently found a way to integrate piezoelectric chips into flexible, durable rubber-based circuits. We've seen piezo power sources before, but applications for the new chips are sure to put bounce in your step: energy generating shoes, movement-powered microsurgical devices, and self-charging pacemakers are right around the corner. Interest in green transportation is building as Florida rides high on the government's recently announced grants for high speed rail -- the sunshine state is set to blaze a trail with $1.25 billion in funding. And for those with a soda habit, Takara Tomy's cola-powered RC car is one sweet ride. The biobattery-powered car can convert any sugary liquid to energy, so pour in some Jolt and you're good to go. Finally, love it or hate it -- the launch of Apple's iPad has dominated the newswires all week. While we appreciate the device's toxin-free, recyclable construction and impressive battery life, we have to ask: is it really green?
Ontario and Samsung seal $6.7 billion renewable energy deal
Need to know how much it would cost you and your town to generate 2,500 megawatts of pure green energy? Your wind and solar farm infrastructure costs will come to 7 billion CAD (just under 6.7 billion in US currency), which includes a 437 million CAD "sweetener" to get Samsung on board. Plenty of curmudgeons have emerged from the woodwork to trash the deal as costing above market prices, but this appears to be the largest venture of its kind, so we're not entirely sure "market prices" exist yet. For its part, Samsung will create 16,000 jobs in the area, 4,000 of them permanent, as it builds toward the stated goal of providing enough energy to fully power 4 percent of Ontario's population.

Helix Wind launching wind-powered cellphone tower trials in US and Africa
Helix Wind, a company that produces some very distinctive-looking wind turbines, is getting ready to start new trials in the US and Africa. These trials will involve testing the vertical wind turbines as a source of power for cellphone towers in areas where they may be off the grid, and carry much higher operating costs. The turbines should produce enough energy to power the cellphone towers, and pay for themselves within about six months. The trials are set to start at the end of the month with local Nigerian provider Eltek NSG as a main participant. [Via Inhabitat]
Ricoh erecting 47 x 126-foot solar and wind-powered billboard in Times Square
Ever walk through Times Square and wonder how much electricity all those flashy billboards are soaking up? No? Well, Ricoh has, and now they're doing something about it. Ricoh Company Ltd. of Tokyo is erecting a 47 x 126-foot billboard at Seventh Avenue and 42nd Street that will be completely powered by the sun and wind. Fueled by 45 solar panels and four wind turbines, the billboard won't even need a backup electric generator. On days that the sun and wind aren't enough to power it, it will simply go dark. In the end, the billboard is said to reduce carbon dioxide usage by 18 tons a year. The billboard will go live in December, or just in time for the sun to go dark.
Offshore wind power park to energize Delaware homes
Unlike Rock Port, Missouri, the entire state of Delaware won't be 100-percent wind-powered after Bluewater Wind constructs a $1.6 billion wind park just off its shore, but the state will be able to "light about 50,000 homes a year" for the duration of the 25-year contract. Said agreement was just nailed down between the aforesaid firm and Delmarva Power, and it hopes to start powering homes via wind by 2012. The offshore site will sit around 12 miles off Rehoboth Beach, with a number of turbines to be planted 90-feet into the sea floor and sport three blades apiece measuring 150-feet long. It's noted that vacationers and locals alike won't be able to notice the park from the beach except on a few remarkably clear days, but if their energy bills sink because of it, we don't really think they'll mind, anyway.
Broadstar Windsystem's AeroCam wind turbines break elusive price barrier
As wind energy becomes a practical necessity, designers are scrambling to make the giant spinny things as visually inoffensive as possible. Some are small, some are off in the sea where we can't be bothered, and some just look really pretty. In this case, Broadstar AeroCam developed this handsome horizontal-axis turbine that can be installed in any number of configurations and shipped easier than other turbines, making it a viable solution for those who don't want to erect a giant pole or get involved in construction. AeroCams work on the physics of air lift -- like wings on a plane -- resulting in a huge amount of power from a small package given the amount of blades per unit. Broadstar also brags that the system's price is a boon as well -- a 250kW system runs $250,000, which it says makes AeroCam the first wind power system to break the $1/watt cost barrier.[Via Inhabitat]
Micro-turbines output micro-electricity for Hong Kong's micro-apartments
It's not just the fitness club types in Hong Kong attempting to generate a bit of renewable energy, inventor Lucien Gambarota -- the very man responsible for converting all that cardio into voltage -- is showing off some micro-wind turbines for even more power bill relief. There's currently only a single wind turbine on a small outer island providing energy to Hong Kong, the rest of the city just doesn't get enough wind for traditional turbines to do any good. Not so with Gambarota's new micro-turbines, which can generate electricity with as little as 2 mph of wind, and keep turning at all times from the slightest of breezes. The little windmills are actually gearwheels, mounted in a array. They can be arranged in different shapes and sizes, from two to thousands of square meters. The energy is put into a battery, which then powers appliances in the building. Currently the micro-turbines go for about $25 for a set of 20 gearwheels, but that price should drop considerably once they begin to be mass produced.[Thanks, nvyseal]
