To ensure that lithium does not build up and catch fire, batteries could be inspected without taking them apart.

This is Jonathan Koomey's third essay in a series of four this week that highlights, and excerpts from, his upcoming book, "Cold Cash, Cool Climate," which discusses how entrepreneurs and investors can profit from tackling climate change, one of this century’s greatest challenges.

Written by Diane Weisenberger of Hessen, Germany Push-through hunt – that is what Druckjagd means in German and the local paper said it was coming to my neck of the woods. Deer, boar and foxes would be surrounded in the forest, then pushed into the paths of guns, the veritable carpet bombing of precious wildlife. [...]

Folders tend to be on the practical side. Can the 'iPhone of the bike world' change this? Can a folding bike ever be beautiful, even glamorous? They can, of course, be hugely practical, beautifully engineered, even – as London's furiously knee-pumping contingent of commuters turned semi-pro Brompton racers would attest – surprisingly nippy. But beautiful? Some might disagree but I'd argue not. That's why, even as a foldie agnostic (I respect their utilitarian effectiveness but remain largely immune to their charms) I took up the chance to try out the iF Mode, made by Pacific, a Taiwanese firm which, despite being one of the world's biggest manufacturers of folding bikes, is only now for the first time, selling machines under their own name in the UK. While you might not have previously heard of the company, Pacific manufactures Birdy bikes, the German-designed, slightly Heath Robinson full-suspension devices available in the UK for some time, which acolytes hail as a sort of souped-up...

Libertarian thinktank keeps prominent sceptics on its payroll and relies on millions in funding from carbon industry, papers suggest The inner workings of a libertarian thinktank working to discredit the established science on climate change have been exposed by a leak of confidential documents detailing its strategy and fundraising networks. DeSmogBlog, which broke the story, said it had received the confidential documents from an "insider" at the Heartland Institute, which is based in Chicago. The blog monitors industry efforts to discredit climate science. The scheme includes spending $100,000 on commissioning an alternative curriculum for schoolchildren that will cast doubt on global warming. It was not possible to immediately verify the authenticity of the documents. "There is nothing I can tell you," Jim Lakely, Heartland's communications director, said in a telephone interview. "We are investigating what we have seen on the internet and we will have more to say in the morning."...

Tesla's flashy unveiling of its Model X electric SUV/minivan last week looks like it's paid off in reservations. The car company announced on Tuesday that just a day after the launch, Tesla had accumulated reservations for more than $40 million worth of Model X sales.

NOTE: This is a guest post from our partners at the Protect our Coral Sea coalition. Industrial-scale fishing has wiped out 90 percent of the world’s large ocean-going fish. Fisheries continue to collapse. To protect the integrity of our oceans, governments must protect these vanishing species of fish and the habitat on which they rely. [...]

When we finally understood the internet for what it could be, it became obvious that paper documents, whether they were books or marketing plans, would one day become obsolete. But here we are in 2012, and we’ve still got daily newspapers, paper medical records, and lots of massive office printers churning through thousands of pounds [...]

A brief halt to shipping after the terrorist attacks appears to have lowered whales' stress levels, an ocean experiment suggests.

Incandescent light bulbs are really little space heaters with a side benefit of producing some light. They are an old technology that is being phased out for many applications by more efficient alternatives. Now, in addition to the LEDs and CFLs, we can add ESL bulbs, which have started to reach the market, to the available technologies. We've been watching for Electron Stimulated Luminescence (ESL) lighting technology for a few years. It is now commercially available with the introduction of the Vu1 bulb. ESL lighting uses an electron gun to stimulate a phosphor coated surface for illumination, much like an old CRT or television tube. The bulb is actually a vacuum, with no mercury (or anything else) inside it, so disposal and recycling is easier. The Vu1 bulb has an expected lifespan of 11,000 hours, which can be 5 times that of an incandescent and close to that of a good CFL. It uses 19.5 watts to produce 500 lumens, so it falls in between CFL and incandescent in efficacy. The...

Have the patent wars -- that have dominated mobile in recent years -- finally come to cleantech? And what does that mean for startups?

The settlement prompted one hybrid owner to pursue her case against Honda in small claims court.

A refutation of the “cleantech VC has gone bust” argument. The details are always more complex.

Obama’s 2013 budget proposal is out and aside from some increases in support for many of the renewable energy programs the DOE administers, like the Advanced Research Projects Agency-Energy (ARPA-E) and the Office of Energy Efficiency and Renewable Energy (EERE), the most interesting news is that Obama is starting to go after fossil fuel subsidies [...]
