Geoengineering and Unintended Consequences

Human beings have been tinkering with the environment since the invention of fire. Civilization can be seen as an unintended side-effect of humanity’s earliest geo-engineering— irrigating primordial floodplains as we moved from hunting-gatherer to agricultural societies.

Large-scale, intentional geo-engineering designed to counter-effect all the unintended consequences of our carbon-intensive energy systems are now being seriously studied.

Having spent decades battling acid rain and sulfur emissions, the idea of piping hundreds of millions of tons of sulfur into the upper atmosphere to simulate a volcanic eruption feels wrong.

Our personal favorite? The Hugo-Gernsbackian cloud-making fleets. Reflective clouds of vaporized sea-water seems a lot less toxic, and more easily reversible than mimicking volcanoes. Plus, they’re cool looking.

Dr. Seuss designed fleet of gigantic cloud ships saves the planet!

But should global warming pass a tipping point, and enter into a positive feedback loop, well, some of these  ideas might suddenly seem more practical. Particularly to those of us living in coastal regions.

Humanity’s track record with accidentally messing-up ecosystems (the transportation of invasive species, human-caused desertification) guarantee that, should we be lucky enough to live in a geoengineered world, we will doubtless experience the apocryphal Chinese curse. Interesting times indeed.

Retrofitting Halogen Track Lighting with LEDs? Someday soon, we hope.

With energy savings of up to 80% over Halogen, retrofitting your MR16 track lighting with LEDs would seem to be a no-brainer. The problem is, well, it’s complicated. The prices on this type of lighting are falling fast, and the bottom line is; making a big investment now might not make sense.

LED tracklight

According to Wikipedia, there are few standards for MR16 and MR11 compatible LED lamps, and with a large variety of designs varying significantly in beam control, light quality, efficiency and luminous power, getting the right light for your model of track lighting may be difficult. Or impossible. Most LEDs run on DC current; halogens most often run on 12 volt AC current. So your bulb will need to have an integrated rectifier.

If this is all greek to you, it’s probably not the greatest idea to tackle this solo.

Think twice before placing a huge wholesale order from the Pacific Rim. With reputable sources selling dimmable LED halogen replacements for 30-70 dollars a bulb, you have to wonder about the longevity of a 10 or 15 dollar generic knock-off.

In the pioneering spirit of Warm Home Cool Planet, we appointed ourselves guinea pig and ordered fifty bucks worth of the, ah… affordable bulbs to test in one of our living rooms. We’ll keep you posted on the results.

We’re looking forward to these bulbs hitting the mainstream residential market in the next few years. Stay tuned to this channel.

Time to cool off

Red Earth

Our Planet in 2220?

At the Cambridge headquarters of Warm Home Cool Planet we’re well served with local scientific opinions-what with the big brains of Harvard at one end of town and the super-colliding intelligence of MIT at the other. Sometimes the smart folks from Tufts University in our neighboring town of Somerville get overlooked.

That might be changing with today’s Boston Globe article covering the controversial theory expounded by Tufts astrophysicist, Eric J. Chaisson. In a recent paper Chaisson has put forward the theory that even if we solve the environmental problems caused by greenhouse gas emissions, the rate at which we are generating radiant heat through the generation and use of non-renewable energy sources could result in catastrophic changes in the earth’s eco-systems and atmosphere within two centuries.

“What this means for humans is that this is the ultimate limit to growth,” said Dennis Bushnell, the chief scientist at NASA’s Langley Research Center, who urged Chaisson to publish his idea. “As we produce more kilowatts, we have to produce more waste heat.”

Some critics have cautioned that it is impossible to predict what technologies will be developed to handle the problem of radiant heat over the next hundred years or so. And, that if we don’t figure out how to limit the damage greenhouse gases are already causing to our environment, it’s kind of a moot point.

After looking at both sides of this argument, it is the opinion of Warm Home Cool Planet that we need to worry about what’s coming out of the tailpipe first before we consider how hot the tailpipe is.

The First Mention Ever

Sent to us by a reader:

‘I just checked, and Barack Obama’s inaugural address was the first one to mention the role renewable energy will play in our future economic prosperity.”

Since Warm Home Cool Planet is a little too busy keeping our audience updated on all things energy efficient , we’re going to take your word for it, rather than read all other 55 inaugural addresses. There are some good ones though.

For those of you watching at home, you’ll find President Obama’s shout out to the alternative energy industry on the You Tube Clip posted below at 9:25.

OK Computer… now go to sleep.

In a pilot study conducted by Verizon, the company found that Windows “sleep” features can actually cut energy costs by $65 per computer, annually.
Geez, you’d think Microsoft would have enough $$$ to do their own study.
Anyway, here’s the skinny on how much the communications giant is saving by having their PC monitors go zzzzzzzz… when no one is looking at them.
Hey Monitor, you're getting sleepy... very, very sleepy

Hey Monitor, you're getting sleepy... very, very sleepy

Your mileage may vary, but we suggest you check the sleep function is working properly on your own PC or laptop.

T. Boone Pickens Explains his Plan

Not since Ross Perot’s quirky 1992 presidential bid have we been as impressed by an elderly Texan billionaire writing on a whiteboard. This video is worth watching for the illustration of the US wind corridor. (For a different map of potential wind resources click here.)

Picken’s company Mesa Power LLP has put it’s money where his mouth is, making the world’s largest order for wind turbines with GE in 2007, scheduled for delivery in 2010 or 2011.

For T. Boone Pickens, The Answer is Blowin’ in the Wind

Energy independence or bird killing eyesore?

When the Bush administration ignored T. Boone Pickens ambitious Pickens Plan Oil mogul and corporate raider decided he’d just have build support for the massive undertaking himself.

In the video accompanying the PickensPlan.com Web site, Pickens said that getting 20 percent of the U.S.’ electricity from wind and diverting natural gas to transportation could be done in 10 years “if there is the right leadership.”

“I am calling on the next President and Congress to take immediate action in the first 100 days of the new Administration to do whatever is necessary to make this plan a reality. We are asking the American public to get behind this plan and to help us reduce our dangerous dependency on foreign oil. This has to be the number one priority in the country starting today and that’s what this campaign is all about. I am also calling for a monthly report on the reduction in foreign oil imports and a monthly report on progress in the development of natural gas vehicles in this country.”

Picken’s even has a Facebook page for the plan.

Not everyone is overjoyed at some of the specifics of Boone’s proposals. Environmentalists worry that Pickens “Wind Corridor” could be disruptive to migrating birds, many communities in the US have fought wind turbine proposals, referring to the giant towers as eyesores.

Making energy costs visible

DW_ConsumersAMI6

The Citizen Patriot newspaper in Jackson, Michigan ran a story yesterday about the new ‘smart’ meters Consumers Energy customers will start seeing in their homes. It’s actually a visual display panel that will allow their customers to see-and control–energy usage in their homes.

When prices peak, special thermostats could automatically dial down or shut off air conditioning. Lights, appliances and electronics could also be controlled through display panels or connections to home computers that show energy usage or notify customers of high energy costs.

Consumers Energy will be installing units in 6,000 homes over the next year. Sounds like a great program, and judging by the comments this article has attracted, Consumers Energy needs all the good PR they can get. Warm Home Cool Planet is happy to help!
