Adaptation redux

Roger Pielke Jr. has an overheated post up today wondering why I don't care about the suffering of "millions, perhaps billions" of people around the world adversely affected by climate. Oy. I hesitate to reply, but here goes.

Ocean thermal energy conversion

Over at The Oil Drum, Rick Dworsky has an extremely intriguing post up on Ocean Thermal Energy Conversion:

... the Earth has an enormous natural solar collector - the tropical oceans. ... If we can tap into this renewable source, considering thermodynamics and entropy, approximately 1% of it could provide the entire current worldwide demand for energy. More than enough energy is available, we only need a way to get it - in a practical, cost effective, ecologically safe and sustainable way.

Ocean Thermal Energy Conversion (OTEC) is a technology that can extract useful work from solar energy stored in the sea. Since the sea IS the energy storage medium, OTEC offers 'always on' baseline supply -- during bright clear days and dark nights, in still air and ferocious wind storms -- without the expense and complications of artificial energy storage systems.

Apparently this stuff is farther along than you might think. Check it out.

Dumping chemical weapons in the ocean: never a good idea

The Federation of American Scientists Project on Government Secrecy blog ... has the longest name ever. It also has a post up drawing attention to a report that's not easily available in the public domain: "U.S. Disposal of Chemical Weapons in the Ocean: Background and Issues for Congress" (PDF). Here's an excerpt from the summary:

The U.S. Armed Forces disposed of chemical weapons in the ocean from World War I through 1970. At that time, it was thought that the vastness of ocean waters would absorb chemical agents that may leak from these weapons. However, public concerns about human health and environmental risks, and the economic effects of potential damage to marine resources, led to a statutory prohibition on the disposal of chemical weapons in the ocean in 1972. For many years, there was little attention to weapons that had been dumped offshore prior to this prohibition. However, the U.S. Army completed a report in 2001 indicating that the past disposal of chemical weapons in the ocean had been more common and widespread geographically than previously acknowledged. The Army cataloged 74 instances of disposal through 1970, including 32 instances off U.S. shores and 42 instances off foreign shores. The disclosure of these records has renewed public concern about lingering risks from chemical weapons still in the ocean today.

Lovely.

Electric cars a’comin’

I hear from my inside sources -- and by that I mean a press release I was sent -- that a company called Champion Motors of America is going to start manufacturing and selling a line of electric vehicles:

The company envisions its vehicles as workplace alternatives to traditional gasoline-powered vehicles. The line, which ranges from a 2-person personal car to a 14-passenger shuttle, will be offered to the public as well as to anyone interested in becoming a distributor/dealer. The small vehicles can be used for a number of duties calling for a light vehicle such as quick trips to and around industrial parks, college campuses, private communities, hotels and resorts, malls, amusement parks and security operations. According to company literature, they are environmentally-friendly because they are emissions-free and run on rechargeable batteries, are basically maintenance-free and provide relief in cutting the cost of expensive repairs and maintenance. Their lightweight design and compact size allows them to easily go just about anywhere. The company plans on providing technical support and assistance to its customers.

These are mainly for businesses, not consumers, but hey, you gotta start somewhere.
