Urwerk is getting a lot of notice right now. Not for it’s quirky company name, but for it’s UR 202 wind-powered watch that is quite the hit among high rolling technophiles, stylephiles and ecophiles alike. The watch, which uses compressed air from integrated wind turbines and kinetic energy to keep ticking, is made by third generation Swiss watchmaker, Felix Baumgartner and his design partner, Martin Frei. The pair, who met in 1995, shared a passion for design and a desire to take form and function to the next level.

While the use of air-friction isn’t new in the world of clocks (since the 18th century, it has been used in chiming clocks), the Urwerk design duo refined the systems to include dual turbines in their 202 model to automatically wind and prevent over-winding the classic timepiece.

The first series of watches out from this team ran around $150,000 USD. So, there is no doubt that these pretty pieces will be pricey. While the price point may not be realistic for the masses, the UR 202 creates an interesting intersection between technology and design while bringing time and space a little closer together.

There’s a basic law of physics that everyone can agree on: you can’t create energy from nothing. So when an invention comes along and seems to do exactly that, scientists are skeptical. Some get downright prickly. The problem is, these inventions exist, and everyone who looks at it agrees: it works.

Fortunately, no laws of the universe were harmed in the making of this device, though Star Wars geeks like myself could have reason to rejoice.

The Dark Side

The idea stems from some of the most bizarre, puzzling, and dark corners of Physics, specifically Quantum Physics. Here’s the very basic idea: there is energy/matter everywhere in the universe, even the deepest, emptiest depths of space. Since there’s almost no normal energy/matter in the deepest, emptiest depths of space, the fact that all that space exists (and is expanding) means that it must be filled with something. Enter Dark Matter/Dark Energy. It is believed to exist everywhere in small amounts, but since it fills the universe, that means that there’s A LOT of it – as close to infinity as you can get. While this matter/energy is not literally “dark” in any sense of the word, it does prove that energy exists everywhere, and that it affects normal matter so that (in theory) we could use it.

StatoilHydro, a state-run oil company in Norway, recently announced a 2 year test of a floating 2.3 MW wind turbine off the coast of Norway.

Cables will be used to transmit the power to shore for this $80 million pilot project. The turbine has a height of 65 meters above the sea surface and a weighs 138 tons and will be mounted on a buoy 6 miles off shore.

This technology is unique because the turbine will not be stationary. Three anchors will secure the turbine to the sea floor and can be used at depths ranging from 120 to 700 meters.

“We have drawn on our offshore expertise from the oil and gas industry to develop wind power offshore,” says Alexandra Bech Gjørv, head of New Energy for StatoilHydro. Read the rest of this entry »

As a long time proponent of the increased use of nuclear energy, I have been involved in thousands of conversations on the topic. (Trust me, I am a boring guest at a cocktail party and a real pain around the water cooler.) Nearly every one of them eventually included the comment that sounds like a question but is usually offered as a trump card aimed at stopping the conversation – “That sounds pretty good, Rod, but what do you do about the waste?”

That is the point where – if the person that I am speaking to has not totally run out of patience or simply cannot wait to get another drink – the conversation gets really interesting. You see, “the waste issue” is the best news that there is about nuclear power. I am not alone in that feeling; many of my long time colleagues like Ted Rockwell, author of The Rickover Effect, How One Man Made a Difference, believe that the byproducts that remain after producing energy with fission are valuable raw materials that should not be considered to be waste products. (See, for example, Why Throw Away a Priceless Resource?)

As a barrel of oil hovers around $130, the news has been bombarding us with the obvious effects of high oil prices. As most people weep at the pump, some environmentalists are rejoicing. Gas consumption is down, but there are additional hidden costs to high gas prices that leave even green minded folks with a frown.

1-Difficult to Extract Oil & High Environmental Impact

High oil prices are making it economically viable to utilize oil that is difficult to extract. One example of this is just north of the border.

In the U.S., our single biggest source of foreign oil is from Canada. Although this may be reassuring from a foreign policy standpoint, much of this oil comes with a steep environmental price tag. Known as tar sands oil, 2 tons of sand are needed to produce one barrel of oil in a very resource and energy intensive process.

The planets may be aligned to finally make solar competitive with coal, according to an article in Bloomberg.com by Greg Chang. Rising natural gas prices, the extension of tax credits for solar investment, and the near-certainty that carbon emissions caps will be imposed by the next U.S. administration, will make it happen. A concentrated solar thermal plant in California’s Mojave Desert, run by FPL, Inc., uses 550,000 mirrors to concentrate solar power.

“At noon on a typical workday, technicians in a two-story control room monitor a dozen screens showing the heat generated by each array of mirrors. As temperatures creep past 700 degrees, icons blink to red from green, indicating the center is ready to feed electricity to the California grid.”

The resulting steam turns turbines that generate electricity — enough to power 112,55 L.A.-area homes. Concentrated solar thermal’s potential has not escaped the attention of forward-thinking investors with big money:

“Chevron, Goldman Sachs, FPL, PG&E and other companies have filed more than 50 applications with the Bureau of Land Management to lease government-owned desert property for solar power systems. Google’s philantropic division put $10 million into eSolar, a start-up in Pasadena, California.” –Greg Chang, Bloomberg.com

Picture a kelp bed on the ocean floor swaying in the current.
Done?
Now picture an underwater field of bioWave turbines (pictured to your left) doing the same. But, unlike the kelp, supplying one half megawatt of electricity. (In kelp’s defense, it does provide oxygen, food, and a place for the elusive leafy sea dragon to hide.) Using habitat inspired and environmentally friendly design (biomimicry) the team at BioPower Systems have designed, and are now testing, the bioWAVE and bioSTREAM devices. Devices that sway in tune with the oceans currents while producing clean, renewable energy. The Australian company has also focused in minimizing the environmental impact of each device as not to upset the ocean’s many delicate ecosystems. Or, as their website puts it:

These systems will reside beneath the ocean surface, out of view, and in harmony with the living creatures that inspired their design.

I ran across this article at The Oil Drum and thought it was too tasty to pass up. It describes a new design to help concentrated solar power (CSP) increase efficiency and reduce cost.

Here’s the problem: solar thermal collectors focus the sun’s heat onto a clear tube of fluid (see: Intro to Solar Thermal). The collectors generate the most energy when the sun’s rays are parallel with the tube of fluid.  Since the sun moves across the sky throughout the days and seasons, it only reaches this “sweet spot” certain hours each day. But, if the solar collectors could move to track the sun, their power output could increase dramatically. Keep in mind that CSP is one of the most efficient forms of solar power.

On Wednesday I attended an event on Green Technology sponsored by the Midwest Council of the American Electronics Association. Vincent Albanese, SVP of Air Pollution Control at Fuel Tech, a company that produces air pollution control devices for large power generators and heavy industry, shared some startling information and insight:

• Congress is missing opportunities to save energy because of its narrow focus on achieving carbon-emission goals thirty years in the future.
• Older manufacturing companies have no incentive to clean up their plants because the EPA’s New Source Review rule requires that with any physical changes made, companies have to add all new technology.

New source review sounds good to us environmentalists, but in practice it makes rust belt companies avoid upgrades in their current operations that would save vast amounts of energy, because of the expense involved in completely revamping their entire operations. Read the rest of this entry »

Many people envision solar power as rigid silicon panels mounted on a roof. With thin film solar cells, you’re more likely to not see them, or even know they’re there. This article is about a real-life thin film solar project.

Not many bloggers are able to witness the technologies we research and write about. It’s one thing to be able to buy afford a cool “green” gadget (usually not very green), but another to see the many forms of solar, wind, geothermal, etc., which are always changing and developing around the world. So when my employer decided to go solar, you might imagine my excitement.

At the moment I work for Magco Inc., a Tecta America company. Tecta is a national commercial roofing corporation that can install green roofs, solar lighting, and solar panels alongside a variety of traditional roofing systems. This solar project is pretty straight forward: our building has a big, flat roof on top of a hill without any shade. You’d have trouble finding a sunnier spot for solar panels.

I was double delighted when I heard that they ordered thin-film solar! Naturally inquiring minds wanted to know: why and what kind? Read the rest of this entry »
