Dash for Green Cash

If you invested in green funds the past couple years, you likely lost your shirt--even more so than others--in the current recession according to an article in today's Boston Globe. But the smart money today, the article goes on to say, is in another type of green investing; eco-improvements on your home that will reduce your cost of living.

Nowhere does this seem to be more true than in Massachusetts. I've been looking into installing solar photovoltaic panels on our condo and with the combination of state and federal tax credits and rebates, they are practically giving the stuff away.

Why We Should Let the Big Three Fail

ƒ
[This blog originally appeared in New Scientist. See the original here.]

The second attempt at a federal bailout for the Big 3 US automakers fell apart early this morning when their union refused to trim their workers' rather cushy benefits packages.

I say good riddance. Let the dinosaurs die. It's time for auto industry version 2.0.

One alternative getting a lot of attention recently is Better Place, a Silicon Valley start-up with a business model that could quickly turn the automotive industry on its head.

Basically, it's a refueling system for all-electric vehicles that, if successful, would lead to a complete gutting of the internal combustion engine.

Better Place doesn't sell cars; rather, it sets up a national grid of refueling stations, ideally powered by renewable energy. Drivers swap out their drained batteries for fresh ones at their stations in a matter of minutes and pay Better Place by the mile, like buying minutes for a cell phone.

Israel, Denmark, Australia, and, as of last week, Hawaii are all on board. Renault-Nissan will provide the cars with the easy-to-swap batteries, and Japan is testing the company's stations for a remake of their transport system.

Tom Friedman plugged this new model earlier this week - and dissed what was then a likely bailout for the Big 3 - in an editorial for the New York Times saying:

"Our bailout of Detroit will be remembered as the equivalent of pouring billions of dollars of taxpayer money into the mail-order-catalogue business on the eve of the birth of eBay... into the CD music business on the eve of the birth of the iPod and iTunes... into a book-store chain on the eve of the birth of Amazon.com and the Kindle... into improving typewriters on the eve of the birth of the PC and the Internet."

The Better Place model may be a part of the solution, but until heavy, steel-body autos go on a serious diet, battery-driven cars are going to be prohibitively expensive.

Amory Lovins of the Rocky Mountain Institute gave a great talk at Harvard last week on Hypercars or ultralight vehicles made of advanced composites (that is, carbon fibre instead of steel) that, by virtue of their light weight, are 3-5 times more fuel-efficient.

Advanced composite car ideas have been batted around for years: GM did a one-off concept car back in 1992, but it seems no one has been able to get the economics right for mass production. Until, perhaps, now.

This summer, a Japanese paper reported that Nissan, Honda, and Toray - the largest carbon fibre manufacturer in the world - are coming together with the goal of making vehicles 40% lighter than today's models.

Last week I proposed giving the Big 3 whatever they asked for so long as the money was tied to significant CAFE standard increases. Now, I'm taking it back. The automotive industry is changing too quickly and GM, Ford, and Chrysler are too far behind.

I say if the US is going to compete in a new, fuel-efficient world, it will be with scrappy start-ups that aren't tied to 20th-century pensions. What do you think?

Energy From The Deep

[The following is a story I wrote on Ocean Thermal Energy Conversion [OTEC] for NewScientist.com]

OTEC only makes sense where the temp. dif. between surface and deep water exceeds 20℃

FOR a company whose business is rocket science Lockheed Martin has been paying unusual attention to plumbing of late. The aerospace giant has kept its engineers occupied for the past 12 months poring over designs for what amounts to a very long fibreglass pipe.

It is, of course, no ordinary pipe but an integral part of the technology behind Ocean Thermal Energy Conversion (OTEC), a clean, renewable energy source that has the potential to free many economies from their dependence on oil.

"This has the potential to become the biggest source of renewable energy in the world," says Robert Cohen, who headed the US federal ocean thermal energy programme in the early 1970s...

STORY BEHIND THE STORY
It's been fun writing about these once-orphaned renewable energy schemes that got a lot of RnD $ back in the day and are now getting a serious second look. I wrote one a couple years back on algae biofuel that feeds on CO2 exhaust that now looks like it might become a reality. In both cases, retired DOE guys who headed up the research in the 70s are suddenly in hot demand as they are the only ones with any hands on experience.
After this story on OTEC went to press, I heard that Taiwan is going in with Lockheed on their 10MW pilot plant off Hawaii.
