Unmanned Solar Aircraft Aims to Compete Commercially With Satellites and Drones
Posted by Genevieve Klien in categories: business, drones, robotics/AI, satellites, solar power, sustainability
At 35 meters, the wingspan of the new BAE Systems aircraft equals that of a Boeing 737, yet the plane weighs in at just 150 kilograms, including a 15 kg payload. The unmanned plane, dubbed the PHASA-35 (Persistent High-Altitude Solar Aircraft), made its maiden voyage on 10 February at the Royal Australian Air Force Woomera Test Range in South Australia.
“It flew for just under an hour—enough time to successfully test its aerodynamics, autopilot system, and maneuverability,” says Phil Varty, business development leader of emerging products at BAE Systems. “We’d previously tested other sub-systems such as the flight control system in smaller models of the plane in the U.K. and Australia, so we’d taken much of the risk out of the craft before the test flight.”
The prototype aircraft uses gallium arsenide–based triple-junction solar cell panels manufactured by MicroLink Devices in Niles, Ill. MicroLink claims an energy conversion efficiency of 31 percent for these specialist panels.

Newron EV-1 begins taking deposits on its beautiful wooden e-motorcycle
Posted by Quinn Sena in categories: sustainability, transportation
Last year we ogled the Newron EV-1 electric motorcycle upon its debut, but questioned whether it would ever make it to market. As of today though, the company has ended speculation by opening pre-orders for the highly unique, wooden-bodied electric motorcycle.

Company Uses Mushrooms to Grow Plastic Alternatives
Posted by Quinn Sena in categories: food, sustainability
Plastic has become ubiquitous in our home and work lives over the past 50 years. It is pliable, durable, easy to make, and hard to break. Plastic may be convenient and useful, but it also won’t break down naturally, which makes it a long-lasting pollutant. A recent study published in Science Advances found that humans have produced 8,300 million metric tons of plastic to date, which is 25,000 times the weight of the Empire State Building. Seventy nine percent of that has ended up in landfills or the ocean. If we continue making plastic at our current rate, that figure will reach 12,000 metric tons by the year 2050. Plastic pollutants are showing up in drinking water all over the world as well as in food products, like beer. We have a serious problem.
Humans are “addicted” to plastic, says Gavin McIntyre, chief scientist and co-founder of Ecovative, a company aiming to reduce our dependence on plastic and other toxic or non-decomposable materials by making biodegradable alternatives. For several years, Ecovative has been manufacturing eco-friendly packaging supplies, and has just received a grant from the Environmental Protection Agency to further develop its new product, mResin, an alternative to the harmful adhesives found in most paneling and insulation.
Ecovative products, unlike most synthetic plastics that are made from crude oil, are grown from mycelium—networks of fungal or mushroom roots. In nature, fungi break down waste, such as old leaves, dead plants, and pieces of wood, and use it to propagate. Ecovative harnesses this natural process and grows the mycelium into various shapes and structures, from pieces of furniture to packaging materials like MycoFoam, its trademarked Styrofoam substitute.

Tesla Model 3 gets 350-mile in new ‘long range mode’ test
Posted by Genevieve Klien in categories: Elon Musk, sustainability, transportation
CEO Elon Musk congratulated the Tesla team after the Model 3 got 350 miles of range on a single charge in a new test on range mode.
Officially, Tesla Model 3 Long Range had a range of 310 miles on a single charge, but Tesla has found some optimizations in recent months – leading to an increase of EPA-rated range to 322 miles.

Elon Musk shares the science fiction book series that inspired him to start SpaceX
Posted by Genevieve Klien in categories: Elon Musk, space travel, sustainability
As a teenage boy, Elon Musk felt a “personal obligation” for the fate of mankind, according to the book “Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future” by Ashlee Vance.
Musk’s love of books and the lessons he took from them inspired him to create “cleaner energy technology or [build] spaceships to extend the human species’s reach” in the future, according to Vance.
One set of those books Musk still recommends today: the seven-book “Foundation” science fiction series by scientist and author Isaac Asimov.

New Battery Tech Could Double Electric Car Driving Range
Posted by Genevieve Klien in categories: food, sustainability
Current-day EVs generally use graphite anode batteries, which tend to provide shorter range compared to their gas-guzzling brethren, according to the researchers. Silicon anodes, on the other hand, have ten times the capacity — but are much worse at holding their capacity over time.
Frying Batteries
The team, led by Hun-Gi Jung, came up with a way to keep these silicon anodes stable by using “a simple thermal process used for frying food,” according to a statement, which involves the use of water, oil, and starch.

Home: Apparently people are cool with lumber as an industry, as opposed to lumber as a carbon collector

Choice is the one thing our creators gave us. Me, personally I prefer hemp, and not just because I smoke the female version for medicinal reasons, but because scientifically it makes sense, and can help unscrew #AmericanFarmers…Yes we need more forests, not less. However, we don’t need to use trees, when we have hemp. Pembient can 3D Print ivory, thus making animal Ivory obsolete, yet people still kill for Ivory. We can make wood products from hemp, yet we still fell trees. #HowDumbAreWe
Eco-Friendly Our hemp is grown using sustainable methods, which helps eliminate deforestation.
Made in the USA All hemp growth and material production is conducted in the United States of America.

Tesla wins court approval to build Gigafactory in Germany
Posted by Omuterema Akhahenda in categories: sustainability, transportation
How do you make “environmentally friendly cars” by destroying the environment. This is really uncool. “What would Greta Do?” Environment activists had managed to halt the felling of the trees two days ago, arguing that Tesla’s Gigafactory would affect local wildlife and water supply. However Tesla is said to plant 3 trees for every one it cuts down. Is that good for the wildlife in the forest and the water table?
A high court in Berlin has allowed Tesla to continue clearing a 92 hectare forest for its massive Gigafactory. The court rejected pleas from environment activists and said that its decision was final.

Scientists develop safer lead-based perovskite solar cell
Posted by Saúl Morales Rodriguéz in categories: solar power, sustainability
Researchers at Northern Illinois University and the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) in Golden, Colorado, are reporting today (Feb. 19) in the journal Nature on a potential breakthrough in the development of hybrid perovskite solar cells.
Considered rising stars in the field of solar energy, perovskite solar cells convert light into electricity. They’re potentially cheaper and simpler to produce than traditional silicon-based solar cells and, on a small scale in laboratory settings at least, have demonstrated comparable efficiency levels. But key challenges remain before they can become a competitive commercial technology.
One major challenge is the use of lead. Most top-performing hybrid perovskite solar cells contain water-dissolvable lead, raising concerns over potential leakage from damaged cells.
