US launches first commercial tidal power project this summer, Maine to reap moon’s gravitational benefits

US launches first commercial tidal power project this summer, Maine to reap moon's gravitational benefits

Solar may be the green energy source that’s been hogging the headlines lately, but there are other fossil-fuel free ways that can help meet society’s electrical needs. One of these is tidal power, and the US is set to start harnessing the ocean’s electricity-generating potential this summer with the TidGen Cobscook Bay project — the first such commercial project in the States. Located just off the coast of Eastport, Maine, turbines will be placed in 50-100 feet deep water to take advantage of the 100 billion tons of water that flow in and out of Cobscook Bay each day. When the project goes live, it’ll feed into the public power grid and generate enough juice to power between 75 and 100 homes, and the plan is to eventually install enough turbines to generate 3MW of power — which should cover the needs of over 1,000 homes and businesses. There’s more info, plus plenty of political self-congratulation in the source below.

Satellite shots show intense Greeland ice sheet melt

On July 8, around 40% of the massive ice sheet that covers the country of Greenland was at a point of thawing at or near the surface. But by July 12, that amount had risen to 97%. Just check out the image here. Anything in light pink is classified as “probably melt” while areas in dark pink are simply classified as “melt.”

The images come from NASA, showing that the melted area is the greatest it has ever been in the 30-year history of satellite observations. This doesn’t lead to any specific conclusions about global warming or climate change, or to the cause of why this massive ice sheet is melting, but the images don’t lie and this is clearly an issue. This kind of ice melt has historically only occurred once every 150 years on average.

“The Greenland ice sheet is a vast area with a varied history of change. This event, combined with other natural but uncommon phenomena, such as the large calving event last week on Petermann Glacier, are part of a complex story. Satellite observations are helping us understand how events like these may relate to one another as well as to the broader climate system,” said NASA cryosphere program manager Tom Wagner.

Inhabitat’s Week in Green: liter of light project, space tourism and a ‘Hyperloop’ train

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.

DNP Inhabitat's Week in Green TKTKTK

This summer has been one of the harshest in recent memory in the US, with record heat waves and more than half of the country experiencing the worst drought conditions in more than 50 years. And in an even more troubling development, an iceberg twice the size of Manhattan broke away from Greenland this week. The need to develop clean alternatives to fossil fuels and water-saving technologies is more urgent than ever, but we’re making progress in several key areas. In California, scientists fired 192 lasers onto a single point, producing an amazing 500 trillion watts of energy and bringing them one step closer to starting a nuclear fusion reaction that would produce an unlimited supply of clean energy. In another promising development, a teenager in Egypt figured out a way to turn the country’s plastic waste into $78 million worth of fuel.

Researcher calls platinum wrong for fuel cell development, looks elsewhere for efficiency

Researcher calls platinum wrong for fuel cell development, looks elsewhere for efficiencyHearing that fuel cells aren’t the most efficient thing in the world shouldn’t take you by surprise, but a determination by one Alfred Anderson just might. The chemistry professor from Case Western Reserve University is now making a case for using something other than platinum as the “catalyst most commonly used to convert chemical energy to electricity.” According to him: “Using platinum is like putting a resistor in the system.” To be fair, Anderson still isn’t sure which material should replace it, but he’s adamant that wizards in the field should be spending their time looking for substitutes instead of tweaking platinum further. Currently, he’s working with other researchers in order to find something that’ll one-up what we’re using today, and if you’re into oodles of technobabble, you can dig into the ins and outs of his claims in the source link below.

Inhabitat’s Week in Green: origami Yoda, high-speed rail line and a self powered building

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.

DNP Inhabitat's Week in Green origami Yoda, highspeed rail line and a self powered building

It’s been a great week for two of our favorite things over at Inhabitat: LEGOs and Star Wars. First, a group of LEGO builders from LEGOLAND Windsor built the tallest LEGO tower ever, snatching the title back from South Korea and returning it to the UK. Then, using 152,455 LEGO bricks, Rolls-Royce built a half-size replica of the jet engine that powers the Boeing 787 Dreamliner. In one of the most ingenious LEGO constructions ever built, LEGO pro Rene Hoffmeister built a barrel organ that plays the Star Wars theme song. And in other Star Wars news, we reported on the renovation of Luke Skywalker’s boyhood home in Tatooine (actually it’s in Tunisia). And finally, we shared a photo of this 7-centimeter-tall origami Yoda — the most adorable bit of Star Wars memorabilia ever made.

Bob Mansfield: ‘all eligible Apple products are back on EPEAT’

Bob Mansfield 'all eligible Apple products are back on EPEAT'

Here’s something you don’t want happening when you’re trying to wrap up a career, plan a jaunt to Moorea and generally goof off while waiting for the final checks to clear: large numbers of people demanding that you change something. That’s probably what one Bob Mansfield is dealing with, just weeks before he’ll turn in his Apple employee badge and do… well, whatever he wants. Just six days after the company yanked its products out of EPEAT’s green registry, all eligible Apple products are back. Why? Well, many cities, entities and organizations (San Francisco, we’re glaring at you) won’t purchase products that aren’t on the list, and according to a letter from Bob (embedded in full after the break), the removal “was a mistake.”

He also notes that “Apple makes the most environmentally responsible products in our industry,” and that no other company in this industry can say that its entire product line “exceeds the stringent ENERGY STAR 5.2 government standard.” Curiously, he also states that Apple’s relationship with EPEAT “has become stronger as a result of this experience,” which sure makes one wonder what went down to begin with. Now, Bob — retirement. No more emails. Focus.

Inhabitat’s Week in Green: rise of solar power, cardboard forts and a Death Star ping pong ball

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.

Inhabitat's Week in Green rise of solar power, cardboard forts and a Death Star ping pong ball

It was a big week for superlatives in clean tech and green architecture — particularly in Europe. First, construction on The Shard, architect Renzo Piano‘s shimmering, 72-story skyscraper, wrapped up in London, making it the tallest building in Europe. A nighttime celebration, complete with a laser light show accompanied by the London Philharmonic Orchestra was held. Just about a mile down the river, construction is moving forward on Blackfriars Station, the world’s largest solar bridge. The historic bridge is being fitted with a solar array that will produce 900,000 kWh of clean electricity per year. And in Germany, solar producers have set a new world record, pumping an astounding 14.7 TWh of electricity into the grid during the first six months of 2012 — 4.5 percent of the country’s total power production during that period.

Inhabitat’s Week in Green: energy-harvesting toilet, LED lightbulb overhaul and a floating, solar-powered resort home

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.

DNP This Week in Green TKTKTK

LED technology shone brighter than the summer sun this week as artist Bruce Munro unveiled plans for his largest lighting installation ever — a field of thousands of LED flowers that will spring up next year at Australia’s Ayers Rock. Best of all, the entire installation will be powered by solar energy! We also saw Rice University flip the switch on its new Epiphany Skyspace — a green-roofed pavilion that’s topped with a brilliant blue canopy of light. If you’re still not convinced that LEDs are the future, we recently produced two videos that are sure to show you the light — check out our interview with five professional lighting designers on today’s state of the art LED bulbs and watch as we give Inhabitots editor Julie Seguss a light bulb overhaul that shaves over $400 off her utility bills. And if you’re ready to make the switch, check out our guide to 24 gorgeous green lamps that look great with LED bulbs.

This week saw some exciting new developments in the realm of renewable energy. First, a group of scientists in the UK developed a new energy-harvesting device that attaches to the joint between the thigh and shin. The device could be used to power monitors and mobile devices, to name a few possible applications. Meanwhile, scientists from Nanyang Technological University in Singapore have invented a new toilet that turns human waste into electricity while reducing the amount of water needed for flushing by up to 90 percent. That’s what we call, win-win!
