The International Union for Conservation of Nature surveyed 47,677 of animal and plant species this year, ultimately listing 17,291 of the count under Red’s List of endangered species.

The Switzerland-based environmental group conducts a yearly examination of plant and animal species and 2009’s list topped last year’s by 2,800. However, the group admitted that the list is incomplete, and there remain millions of other specimens yet to be surveyed.

A partnership between two companies will develop a home energy monitoring device for residential solar power installations.

Two startups – Tendril Networks, known for its home energy monitoring technology and Fat Spaniel technologies, a solar panel monitoring company – make up the partnership. The purpose of the partnership is to develop a monitoring device for homes that can gauge the sun’s intensity for any particular time and automatically adjust, or even shut down, home appliances as needed.

Because of their enormous body size, whales have been thought to contribute a considerable amount of carbon dioxide to the total greenhouse gas build-up whenever they exhale. However, Trish J. Lavery of Flinders University in Adelaide, Australia claims they – the sperms whales of Southern Ocean, at least – are falsely-accused and that they live quite a carbon-neutral life.

During the October 13 Biennial Conference on the Biology of Marine Mammals in Quebec City, Canada, Lavery talked about earlier calculations overlooking the whales’ capacity to offset their carbon dioxide emissions. The 210,000 sperm whales in Southern Ocean should be declared carbon neutral, according to Lavery. The carbon neutral status is achieved by bringing iron from the depths of the ocean to the surface whenever they feed. This extra iron in the water induces plankton growth which in turn traps carbon and prevents it from being released into the atmosphere.

A new Kansas-based company called EcoFit Lighting believes it can make the transition to LED street lighting not only much easier, but also much cheaper.

EcoFit’s design is a retrofit module that slides right into place in existing streetlights, eliminating the need to have a full replacement. The company claims using their product would bring down costs from $700 to $900 (for a complete replacement) to just $400. Savings also come in the form of energy efficiency and extended lifespan as EcoFit’s LED lights are 60 percent more efficient and last six times longer than sodium streetlights. Additionally, as it’s estimated that replacing street lights with EcoFit LED lights would take just five minutes (as opposed to taking up to 30 minutes to fully replace the head), labor costs are also expected to be reduced.

In Taiwan, a new charger technology claims to be able to charge phones without even being plugged into an outlet. That’s because it taps into the power of hydrogen as a fuel source, and is expected to help put Taiwan in the list of purveyor of green technologies.

Scientists from Taiwan’s Industrial Technology Research Institute recently unveiled a charger powered by hydrogen. According to source, the device can fully charge a phone within a couple of hours, although the amount of hydrogen fuel used for that span of time wasn’t mentioned. Tsau Fanghei of the research team says they “hope the hydrogen-powered device can replace current mobile phone recharge systems in 2012.”

While carbon capture and sequestration technology remains controversial, studies to delve deeper into it are ongoing in hopes of presenting one way to alleviate emission levels. A team from MIT has been studying a carbon capture and sequestration (CCS) technique called pressurized oxy-fuel combustion. This process converts the carbon dioxide emissions of a power plant into a pressurized liquid stream meant to be pumped underground. Team leader Ahmed Ghoniem of MIT claims that his team is the only one conducting an academic study of “pressurized combustion system for carbon dioxide capture.”

The Arakan forest turtle was once thought to be extinct until some specimens were found peddled as food in China. According to LiveScience, it was 1908 since a live specimen – just a single one – was last collected by an Army officer from Britain. But in an elephant sanctuary in Myanmar, a team of Wildlife Conservation Society (WCS) personnel discovered five endangered turtle species, one of which is the Arakan forest turtle. The animal is small, with adults measuring less than a foot in length, and is characterized by its brown coloring and block mottling. Like many other turtle species in Asia, the Arakan forest turtle’s existence has been threatened by poaching.

A team of scientists from the University of Texas at Austin has developed a type of spray-on solar cells that could lower costs of production dramatically.

The concept of spray-on solar cells is by no means a new approach – the Australian National University has been working on one for the past three years. The University of Texas at Austin team led by engineer Brian Korgel uses copper indium gallium selenide (CIGS) as the main component for the ink used to manufacture the solar cell. This nanoparticle ink allows manufacturers to completely deviate from the conventional expensive method of solar cell production. Using this ink, solar cells can be made through a roll-to-roll printing process, similar to how newspapers are printed. Plastic substrate and stainless steel are a couple of possible bases for the printing.

The northern Madagascar spider tortoise, one of the three subspecies of Pyxis arachnoids, is currently facing a threat to their population brought about by poachers.

The spider tortoise is small compared to other tortoise species, and is characterized by the presence of web-like patterns on adult shells. The northern Madagascar spider tortoise subspecies (P. a. brygooi) can only be found in a narrow strip on the coast. Since they’re endemic and hence, can easily be caught, the subspecies is currently “extinct across 50% of its former historical range.” Senior wildlife biologist at Nautilus Ecology UK, Ryan Walker, conducted this population survey last March, and came to the conclusion that the wild population of the northern Madagascar tortoise has fallen by 90%, mostly due to massive collection for illegal pet trade.

After less than a year of construction, the Sierra SunTower Plant that’s touted the first of its kind in the USA was finally officially launched by eSolar.

Located in Lancaster, California, this is the first eSolar concentrating solar thermal power plant with 24,000 mirrors instead of the company’s usual 12,000. The entire plant was built less than a year through the use of eSolar’s pre-fabricated components. Within that span of time, the plant’s heliostat mirrors have been utilized in various occasions, not to harness energy, but to greet the company CEO on his birthday and celebrate USA’s Independence Day. As was intended by Southern California Edison and eSolar, the 5-megawatt Sierra SunTower plant was connected to the grid this August 5 to power 4,000 homes in California’s Antelope Valley.
