I’ve been testing a device that just been introduced called the PowerGorilla. It’s a portable power pack that acts an emergency back-up charger for your laptop computer other other electronic gadgets. The battery inside the PowerGorilla is a lithium-ion and weighs just 631 grams (1.4 pounds). The charger will give you an extra 2-5 hours […]

Note: If you looking for AA-sized LifePO4, you can find them here. Soon, we’ll probably be seeing Lithium Iron Phosphate (LiFePO4) batteries being used in most electric cars and bikes. This new battery type is set to dominate the market. Based upon lithium ion technology, LiFePO4 batteries offer many advantages over lithium cobalt dioxide (LiCoO2)

The new Blue Ridge Parkway Destination Center has just been completed in North Carolina. It’s a beautifully designed building that is also highly efficient — it will use 75% less energy than a comparable conventional building. The building has Trombe walls: a very clever feature that will reduce the building’s heating load by 35% alone!

See our updated report on Electric Cars In 2011. At MetaEfficient, I am a strong advocate of car-free living (see my review of the books How To Live Well Without Owning A Car and Car-Free Cities). However, clean, electric vehicles can be useful in some situations. If you recharge them using a renewable energy source

The Proximity Hotel is proof that a hotel can be very green without sacrificing the comfort of its guests. The hotel is located in Greensboro, North Carolina, and it achieved a Gold LEED certification this year from the U.S. Green Building Council. The Proximity uses 36.5% less energy and 30% less water than a conventional

Architecture firm Foster + Partners won an international competition to design a green complex that will fill an entire city block in downtown Singapore. This complex will be on the leading edge of green design. It will incorporate arrays of solar cells on the buildings’ facades. Ribbon-like canopies (also covered with thin-film solar cells) will

Costa Rica is a country rich with renewable energy. In fact, it gets about 99% of all its electrical energy from clean sources, and it’s aiming to be the first country to become carbon neutral (more about that below). Some of Costa Rica’s energy sources include geothermal energy, the burning of sugarcane waste and other

The German Reichstag is expected to become the greenest parliament building in the world, thanks to a decision to rely solely on renewable energy. From late summer the building is due to swap to green power sources such as water, wind and solar energy, replacing the conventional power that it has largely relied upon until

The “Clean Technology Tower” is a highly efficient building which will be constructed in Chicago. The tower will have wind turbines positioned at the corners of the building, to capture wind at its highest velocity as it accelerates around the tower. At the apex, where wind speeds are at a maximum, a domed double roof
