The nuclear bottleneck
As it turns out, no matter how much harumphing gets done in Congress, there is only one company in the world that forges the $350M dollar reactor cores -- and, as Bloomberg reports, they're turning them out at a speed of 4 per year. Ingots, as the giant steel cores are called, are only produced by Japan Steel Works Ltd., consequently an old samurai sword producer. The CEO maintains that their closest competition is still 5 years away from matching their technology. Oops.
Representatives at JSW worry about this new resurgence in the popularity of nuclear power, saying that their capacity is not set to meet the new demand. Congress has already earmarked $18.5 billion for nuclear loan guarantees, but there's really no clear picture of how fast this money can be spent with the current bottleneck of nuclear reactor cores. According to Earth2Tech, developers are laying out deposits as big as $100M for projects as far out as 2015.

Airlines feel the pinch of high gas prices

If there's a silver lining in the dramatic jump in fuel prices, it's the fact that older, dirtier jets will be sold or retired from service, helping to lower the emissions that the airline industry has been taking heat for. Continental is set to retire 63 old jets, replacing them with more efficient jets from Boeing in 2009. Here are some measures that the other major carriers are taking, from the article:
•Delta will dump 15-20 older, less efficient mainline jets, plus 20-25 regional jets. The change will result in a 10% reduction in Delta's domestic flying capacity by year's end. It also will eliminate at least 2,000 jobs.
•United will remove 10-15 older mainline jets to partially offset fuel costs that could swell $1.2 billion more than planned this year.
United has led in raising fares to offset rising fuel prices. But CFO Jake Brace warned that the industry likely won't be able to raise fares enough to fully cover higher costs.
•JetBlue will sell four more Airbus A320s, on top of the six it previously announced that it would sell. In total, 10 A320s will leave the fleet by early 2009.
•US Airways will fly three fewer planes during the second half of the year than previously expected and could cut back further, President Scott Kirby said. But he added that despite tough fuel prices "remarkably, the (travel) demand environment remains pretty strong."

Thanks to smog-busting weather, and some significant investment in beatification efforts, four cities in Florida made it into the top 10 -- Jacksonville, Tamp-St.Petersburg, Orlando, and Miami (which took the number one spot). Here's the full list:

Let's just hope that Bill Nye's show will be patterned after the classic Bill Nye the Science Guy. If he could show us simple household ways to do green experiments, crack some corny jokes, and then wrap up with a clever song parody reviewing what we've learned, I think they've got a hit show. Noticeably absent from PG's lineup is Professor Beakman of Beakman's World -- you've got to respect the originator.

5 ways the combustion engine is getting better
by Josh Loposer

Filed under: Cars and Transportation
The good news is that automakers are finding ways to make the old-school engine way cleaner and more energy efficient. New technologies are being tested and put into use right now that will translate into significant gains in fuel economy and reduced emissions in the near future. Here are five of the ways that science is squeezing more juice out of your fossil fuel burner:
- Cylinder/Motor Shutdown -- Manufacturers like GM, Chrysler and Honda are all producing engines that deactivate 2 or more cylinders when they're not needed. Likewise, start/stop technology -- where an engine shuts down when the vehicle is idling and restarts immediately for use -- is integral to most hybrids and will soon be finding its way into conventional motors.
- Direct Injection -- By getting rid of the clunky fuel injection systems of yesteryear, researchers are finding that engines can achieve both better fuel economy -- some claim up to 20% better -- and a more complete burning of fuel, read lower emissions.
- Smaller Engines -- You're not likely to see too many V8s in the future, but you might not lose that much power either. Smaller engines can be supercharged to get more power, while they also leave room for a more aerodynamic body design.
- Switching to Diesel -- Diesel sedans have natural advantages in the areas of durability and fuel economy, but the trouble has always been emissions. Now, companies like Mercedes and Audi are releasing 'clean diesels' that neutralize the heavy exhaust that is associated with diesel.
- Lighter is Better -- In terms of an engine's actual weight, and the components which the engine operates, automakers are finding ways to lighten the load. Automakers are making significant gains by simply using lighter materials and taking stress off the engine by using electric-powered components.
Huge woodburning stove to power Scottish homes

Ok, not exactly a stove, but a powerplant that operates entirely on forestry waste. The Steven's Croft Power Station near Lockerbie, Scotland, was officially opened this week, becoming the the largest wood-fired power station in the UK.
Because Scotland engages in sustainable management of its forests it has ample wood waste, which until now had been largely, um, wasted. However, the new plant will use that residue as well as "specially grown willow" to generate 44MW of electricity - enough to power some 70,000 homes.
Woodburning is also a surprisingly clean form of power generation, and according to the govenment will save up to 140,000 tonnes of greenhouse gas emissions annually (although the press release doesn't say compared to what.) The plant has the added advantage of making the surrounding area smell as festive as a roaring fire on Christmas Eve.
Burning biomass - in this case what's called "woody biomass" - is part of the Scottish government's plan to generate at least half of its electricity from renewable sources by 2050.

Corn-based ethanol could smother the Gulf
by Josh Loposer

The 'dead zone' in the Gulf of Mexico is thought to be caused by agricultural pollution, i.e. nitrogen fertilizer, that is carried by the Mississippi and then dumped into the ocean. While fertilizer doesn't seem like the biggest environmental threat to the ocean, it results in a pretty nasty suffocating condition called hypoxia. Phytoplankton thrive on this fertilizer and bloom like crazy in waters where it's in high concentration. The problem comes when they start to die and sink to the bottom -- their decomposing bodies literally suck oxygen out of the water.
All the excitement over biofuels in the last few years has caused a major spike in corn production -- and it just so happens that of all the staple crops in the US, corn is the one that requires the most watering and fertilizer. When you mix heavy irrigation and tons of nitrogenous fertilizer, you get major runoff.
In the past, farmers were encouraged to rotate their fields between corn and soybeans -- a lower maintenance crop -- checking the amount of runoff and thus regulating the size of the dead zone. Now that the market for ethanol is blowing up, groups like the EPA are getting really worried about the possibility that corn will be in heavy rotation up and down the Mississippi Basin.
Oysters: Sexy and recyclable
by Kelly Leahy

Oyster populations are depleting and coastal states have started sinking batches of empty oyster shells back into the water to grow new beds. Once the shells are in the water, they provide homes for many organisms, including oyster larvae. North Carolina is the front runner in oyster recycling with several oyster shell drop off sites and legislation making it illegal to throw them away.
Oysters not only make for pricey appetizers but they also filter up to fifty gallons of water a day, keeping waterways clean which is one reason why oyster beds are being encouraged outside of waste water treatment plants as far north as New York City. These particular critters won't end up on your plate, however.
Timberland tells you how much carbon is in your footprint

Ok, fashionistas, it just got a little easier to green up. Footwear and clothing maker Timberland has begun putting labels on some of its products which indicate how much carbon was emitted in its manufacture.
Carbon scores range from 1 to 10, with 1 being absolutely Gore-worthy and 10 the sartorial equivalent of a coal-powered Hummer. Currently Timberland is labelling about 60 types of boots and shoes, but plans to expand the practice to all its products by 2010.
On a related note, rapper/producer/composer Timbaland declined to comment on his carbon footprint, but did note that he was "well-equipped."
