H3X claims it’s tripled the power density of electric aircraft motors
Weight is a big deal in aviation – and that goes double for electric aircraft. Every pound carried skyward represents a pound less payload you can carry, a reduction in the range you’ll get from your battery or hydrogen tank, and ultimately a loss of money for the owner.
New anti-poaching motion sensor recognizes when wildlife is on the run
Modern sensors have given conservationists a powerful new tool in the fight against poaching. A new research project at the University of Twente could harness this technology in yet another useful way, by mixing motion sensors with machine learning to recognize when wildlife is responding to a nearby threat.
Amazon tribes to use drones to detect illegal deforestation in Brazilian rainforest
Indigenous rights’ groups and WWF International are beginning to train Andean tribes people deep within the Amazon rainforest in the use of drones so that they, as forest-dwelling specialists, can help protect wildlife, and identify, compile evidence for, and report on, illegal logging activities.
“World’s fastest electrodes” triple the density of lithium batteries
Such an energy and power density boost could be revolutionary for electric cars, motorcycles, bikes, and other emerging ground transport modes, as well as a huge potential leap forward for the electric aviation space.
Mack delivers world’s first-ever electric garbage truck to end user
The people at Republic Services — an “industry leading” waste management company operating in North Carolina — will test the LR Electric model on one of its residential recycling collection routes.
Universal Hydrogen and Magnix building world’s largest hydrogen plane
A new LA-based fuel logistics startup, Universal Hydrogen, has embarked on a project to develop a retrofittable hydrogen powertrain for existing airliners, and will test it with a 40-seat De Havilland Canada DHC8-Q300, commonly known as the Dash-8, that will become the world’s largest hydrogen-fueled commercial aircraft.
Zero-emission trucks set to make New Zealand a world leader in hydrogen energy
Kiwi company Hiringa and Hyzon Motors—a U.S. manufacturer of hydrogen fuel cells—signed a “heads of agreement” that would allow Hiringa’s hydrogen-powered electric vehicles (HPEVs) to start hauling freight as early as 2022, positioning New Zealand as a world leader in hydrogen vehicle infrastructure.
