News that has nothing to do with Election 2008

With all the news coverage focused on the election, there are a lot of important and/or awesome things that have escaped attention. Here’s a quick overview of environmental news that’s worth following:

First off, it’s common to get a craving for pumpkin pie around this time every year. But it would take hundreds of people to eat a pie made from this enormous 1,900 lb pumpkin. This behemoth is expected to set a new record for giant pumpkins (a record that has grown bigger every year in recent memory). Maybe this is the monster that Charlie Brown’s been waiting for.

I’m sure that pumpkin wasn’t grown naturally, but no one tried to stick an organic label on it at the store. On the other hand, some businesses have been caught making false environmental claims to sell their products. It can be challenging to tell greenwashed products apart from their legitimate green competitors, but one way to make informed choices is to research the companies involved. Many large companies now publish yearly ‘Corporate Sustainability Reports’ that describe their environmental track record. Corporations are also assigning a dedicated board member to oversee environmental performance. Many of the pro-environment changes that companies are adopting also contribute to the bottom line, and make great economic sense while money is in short supply.

On a related note, the credit crunch is slowing down plans to build new wind farms. Even though wind power accounted for about a third of all new power capacity built last year, the credit climate is making it really hard to line up investors. Wind energy is also running into some problems of scale. Windy days in Washington state are causing salmon deaths in a weird series of unintended consequences. As the wind picks up, wind turbines generate more and more electricity. The excess electricity floods the transmission lines, and automatic controls kick in to shutdown other sources of power. In some cases, this causes hydroelectric dams to idle their turbines and dump water over spillways. If only there was an efficient interstate transmission system, or a better way to store electricity, this whole chain of events could be avoided.

But what if we lived in a world without any need for a power grid? Bloom Technologies is trying to create a lower pollution future based on efficiencies of micro-scale. With small fuel cells, the company hopes to eliminate power loss from transmission lines and bring electricity to the third world. As a bonus, they are designing fuel cells that produce hydrogen as a byproduct – that waste gas could be used to warm homes and fuel vehicles.

Whether cars burn hydrogen or gasoline, tailpipe emissions are pretty much inevitable. This waste product has something that is surprisingly useful though – untapped energy in the form of heat. Researchers are developing new thermoelectric systems that can harvest electricity from tailpipe emissions. If they can keep cost and weight to a minimum, these devices will likely be incorporated into a wide range of hybrid vehicles to boost mileage. The energy recovery isn’t 100 percent, but it can really add up to a serious boost in efficiency:

GM researcher Jihui Yang said a metal-plated device that surrounds an exhaust pipe could increase fuel economy in a Chevrolet Suburban by about 5 percent, a 1-mile-per-gallon improvement that would be even greater in a smaller vehicle.

Queen of England plans array of offshore wind turbines, including biggest turbine ever built

The Queen of England once enjoyed direct rule over 2/3 of the earth’s surface. Her personal authority is a bit less these days, but she still has control over the territorial waters of Great Britain. And, with the backing of the Crown Estate, Queen Elizabeth II can afford to do some really impressive things in her domain. Like building an array of offshore windmills, including the biggest individual windmill in the world.

Her Majesty’s windmill will produce 7.5 megawatts, which is more than twice as much as the previous record holder (GE’s 3.6 MW Offshore Turbine). The company that’s producing the turbine is Clipper Windpower, based in California. They have a proven history building monster wind turbines – including the largest turbine built in the US: the 2.5 MW Liberty Turbine. Details are still being worked out about where the giant wind turbine will be produced, and how it will be shipped to England.

The average British person uses 10-15 kilowatts per day (half of the average American energy consumption), which means that on a windy day this monster turbine will meet the needs of roughly 500-750 people. And the British Crown plans to build multiple turbines, all far out to sea. Many will be invisible to people on land, but the biggest windmill in the world will be nearly 600 feet tall and should be visible for about 18-19 miles.
