Known as "frozen smoke" because of their milky translucent appearance, aerogels are among the world's lightest solid materials. Consisting of 99.8 percent air, they're highly heat-resistant and are an excellent form of insulation. Now, scientists at the National University of Singapore (NUS) have used paper waste to create one.
According to NASA, US airlines could save up to 250 billion dollars between 2025 and 2050. It will all be thanks to green technology pioneered by the agency and industry partners, as part of NASA's Environmentally Responsible Aviation (ERA) project.
A new organic aqueous flow battery technology promises to drastically
lower the cost and sustainability of running energy storage systems.
The technology, which was developed at the Pacific Northwest National
Laboratory, uses low-cost and sustainable synthesized molecules
rather than the usual commodity metals, and could be retrofitted to
Improving on their previous design, scientists at Harvard University have developed a cheap and highly adaptable flow battery that could prove ideal for storing renewable energy throughout the day. The battery is made using Earth-abundant materials, is much safer than previous designs, and could reach the market in as little as three years.
WASP (World's Advanced Saving Project) is set to unveil Big Delta, reportedly the world's largest delta 3D printer, later this week. This 12-meter (40 ft) tall behemoth was brought to life with the purpose of building nearly zero-cost housing through the use of local materials and as little energy as possible, offering quick and inexpensive relief to disaster areas and addressing the future housing needs of a rapidly growing world population.
Toyota and Hino Motors have begun testing a jointly-developed fuel cell bus in Tokyo, Japan. The brief test is designed to will help Toyota evaluate and improve the technology ahead of a possible market launch.
Plastic carrier bags are typically petroleum-based, take a long time to decompose and are often imported from distant countries. They're also tricky to carry when cycling. The new PaperJohn tackles all of these issues. It's a backpack made of biodegradable, 100 percent recycled paper.
Australian Architect Stephen Sainsbury has spent decades researching materials to reduce environmental impact. This has culminated in the development of the Ecoshelta prefabricated modular building system. Based on an extensive evaluation of the environmental impact of building materials and other factors, the Ecoshelta Pods are constructed using a combination of eco-friendly timber, a composite panel roof, the latest wall and floor technologies and marine grade structural aluminum alloy.
As electronic devices are becoming outdated at an increasingly fast pace, e-waste continues to be a huge problem.
That's why scientists from the University of Wisconsin-Madison have
started producing "wooden" semiconductor chips that could almost
entirely biodegrade once left in a landfill. As an added bonus, the
chips are also flexible, making them prime candidates for use in
In tropical countries such as the Philippines, there are plenty of rice
husks ... and also plenty of termites. A group of engineering students
from the University of California, Riverside, recently decided to use
the former to address the latter, by creating termite-resistant
particleboard from rice husks.
