Why Off-Shore Drilling Won’t Make A Dent in U.S. Consumption – Graphically Presented
Saw this first at After Gutenberg, but it came via itsgettinghotinhere from a Architecture 2030 e-news bulletin.
A picture (or in this case, a graph) tells a thousand words.
Second-Generation Solar Trees To Be Even More Awesome Than Real Trees
Much praise has been heaped upon designer Ross Lovegrove since his solar trees first debuted in Vienna in October 2007. Essentially a solar-powered streetlamp — but also a work of art — the structure creates, as the designer puts it, “complex natural forms in a city that can benefit all of society.” They also save energy — and have managed to survive Vienna’s dark spells, with light still being generated even after four days without direct sun. From the article,
“When we were setting up the tree outside it was quite wonderful,” Lovegrove said. “Even when we had one stem, it was incredible, it seemed so insignificant but actually it really stood out and it proves this point that modern technology and design can really lift people’s spirits, it becomes an eye catcher because it’s sort of out of context. The Solar Tree is just a streetlamp but actually some of the small things which can have a big impact on our life are all open for reinterpretation.”
With the first-generation lamps firmly planted on some of Europe’s most famous streets, Lovegrove is now planning on the next-generation design. It will be called the “Adaptive Solar Tree” and, just like the real thing, will feature robotics that seek out sunlight or respond to changes in weather.
Base Jumping Off Of Wind Turbines Probably Not Legal
It was only a matter of time.
With most commercial turbines over 265 ft. tall, they were bound to attract the base jumping crowd. Thing is, they’re not the easiest things to get access to — so we’re wondering whether this crew has an inside man to let them climb to the top. Not to mention turn off the turbine for the jump. Nice view, though.
Peak Energy And What That Means For Food
Note: The following is a peak energy introduction written with Sharon Astyk for our forthcoming book, “A Nation of Farmers: Defeating the Food Crisis on American Soil,” to be published in the Spring of 2009 by New Society Publishers. This excerpt will be a review for those who follow her site and mine but might be interesting to those who have only recently become agitated by $4/gallon gas and who want to learn more. It’s very important that those of us comfortable with this topic help to shape the emerging conversation as one of opportunity not tragedy. No doubt this will mean doing things differently now and in our future but all is not gloom and doom. The rising cost of energy could be an opportunity to address big problems- a catalyst for positive change. With that in mind we must frame this not as ‘the end of the world’ but as the beginning of something better.

Don’t Pin Your Hopes on a “Green” Economy
Both presidential candidates have stumped for a new “green” economy. To me this smells of the supposed transformation to the “information economy” touted only a decade ago. Fortune had this to say on June 30th:
What senators McCain and Obama believe about U.S. energy policy matters – hugely. To fight global warming, the next President will oversee the transition to a new, green economy , which will result in one of the biggest business transformations of the 21st century and potentially one of the largest transfers of wealth since the creation of the income tax.
Why Higher Gas Prices Are Making Me Smile
I’m not naive — I understand that there are severe hardships in store the longer the price of a barrel of oil soars ever higher. But here’s the thing. Every time I pass by my local gas station and see the numbers a couple cents higher than the day before, I smile. For some that might seem odd — and for those that depend on cheap oil, my sentiments are with you. Unfortunately for all of us, those unaffected and those in dire straits, this had to happen. As someone who champions sustainability day in and out, writes about political hangups to change America’s dependency on oil, and laments our lack of investment in renewable energies, this is a blessing in disguise. My only hope is that this continues — and is less of a “rubberband effect” we all experienced in the wake of Hurricane Katrina three years ago.
Why? Because if we are to shift to an economy that is truly self-sufficient and sustainable, we have to be hit hard collectively in the wallets. It’s the only way. As environmentalists, we can release movies, write articles, hold rallies, and buy all the green products in the world — but to to truly bear witness to real change, it has to come from those not directly involved. In other words, everyone must be faced with a burden. For some, climate change might be their burden and buying a hybrid vehicle or biking to work might be the solution. For others, higher gas prices which affect the bottom line might be their burden. In the end, what matters most is that it is a common hardship. Whatever the personal impact, the demanded outcome will be in unison.
Tapping Trees For Diesel Fuel
Australian farmers are embarking on a bit of an experiment to see whether or not they can self-sustain their production using diesel-producing trees. As some may know, I have a bit of a love-affair with plants that can produce — in one way or another — biodiesel. For those looking for an update to my “Adventures In Sustainability” series growing Jatropha — it’s coming soon. The plant is currently in hibernation. But I digress…
The diesel-producing trees are called Copaifera langsdorfii and are native to the Brazilian rainforest. The world has known of their unique properties since about the seventeenth century, but it’s only been recently that harvesting of the petrol is being planned on a grand scale. From the article,
GE Announces New Line Of Efficient Tankless/Hybrid Water Heaters
Tankless water heaters always seemed to make a lot of sense to me. I mean, hot water on demand as opposed to hot water sitting and waiting — seems smart, right? Everytime I go away on vacation, I lower the temp on my water tank to conserve energy, but I know I’m in a small minority. Most people probably go along heating water even when they’re not home for extended periods of time.
Which is why I’m jazzed about GE’s new line of tankless water heaters. For those that don’t need tankless, the electric-hybird heater they’ve got waiting in the wings looks pretty sweet as well. According to the release, the gas tankless on-demand heaters will “save 25 percent in water heating costs on an annual energy bill in comparison to a standard 40-gallon gas tank.” Additionally, the unique design can help avoid up to 25 percent of CO2 emissions tied to water heating.
Even better, earlier today the U.S. Department of Energy created the first ENERGY STAR standard for water heaters. Ironically, water heating was the only major residential energy product that did not have an ES designation — even though it’s one of the largest energy consumers in the household.
Of course, not everyone has access to gas (and truly, for those of us building green homes, reducing the use of fossil fuels is probably on the short list) so GE is getting ready to launch an Electric-Hybrid water heater for next year. According to early tests, this hybrid would reduce typical water heating energy consumption by more than half. While the typical home might use 4800kwh/year, the GE model consumes only 2300kwh/year. Plus, it would retain the same footprint of standard water heaters allowing easy installation.
The Selsam SuperTurbine Will Submerge During Rough Seas!
The Selsam SuperTurbine is one of the best designs I’ve seen yet for a wind turbine that can survive the hostile open seas. It also looks like it might be a bit of a bitch to navigate through with a tanker — not to mention the description states “the SuperTurbine probably won’t sink a vessel.” Makes you feel warm and cozy inside, doesn’t it? Still, based on designs, it looks like the pitch of the turbine should be high enough to keep you safe.
The advantages of this design are many. First, during large and fierce storms, these deep water turbines may intentionally lay down by flooding chambers, or even completely submerge to survive. Bonus! Second, flotation near the surface forms a fulcrum, with the weight of the rotors and driveshaft balanced by a downward force from the mooring below. According to the site, this allows the turbine to bend similar to arching your back to take advantage of wind patterns much more easily. Additionally, the rotors can be staggered, spiral, or in line.
Tesla Gives Us A Magical Mystery Tour Of Lithium Battery Recycling
One of the largest misconceptions of electric cars is that the world will suddenly be inundated with toxic batteries that will seep into ground water, kill your dog, and practically ruin your marriage. Fortunately, battery recycling for green vehicles has been well planned out — even if there currently aren’t many electric-powered cars on the road to be concerned about. Showing us exactly what is possible, Kurt Kelty — an engineer that works for Tesla Motors — recently posted an interesting “Mythbusters” segment on battery recycling — what they’re made of and how they’re disposed of.
Some fascinating tid-bits: First, the Tesla Roadster’s battery pack or Energy Storage System (ESS) contains no heavy metals or toxic materials. By law, this means they could technically be disposed of in a landfill with no problems. However, their usefulness extends beyond pushing a car 0-60 in less than 4 seconds. Apparently, there are major differences in the demands on a battery for use in a high-performance sports car unlike, say, providing backup for a solar array. In fact, once the lithium packs are no longer performing well for the roadster, they may be recommissioned to be used as a power source for off-grid backup or load leveling.
