Scientists have developed a new prototype battery inspired by the anatomy of the human intestine, and the biologically informed approach could pave the way for much more powerful energy sources for our digital devices.
The prototype – which offers up to five times the energy density of the lithium-ion batteries we use in smartphones and laptops – uses a lithium-sulphur cellinstead, and its intestine-mimicking design could finally make these energy-dense batteries long-lasting enough for commercial use.

Scientists have developed a self-healing electronic device that repairs itself when broken, using a special magnetic ink to bridge gaps as wide as 3 millimeters (0.12 inches) – a new record in the field.
The technology could be used in a variety of ways, including batteries and sensors for wearables, because it works much faster than other self-healing materials and requires no external input to carry out the patch-up job. Continue reading This battery heals itself if you break it in half

Martine Rothblatt is not your typical person. She is the founder of Sirius satellite radio and vehicle navigation company GeoStar. When her daughter was diagnosed with a rare life-threatening form of pulmonary hypertension, Rothblatt formed United Therapeutics to market medication for others suffering from the same disease. Because pulmonary hypertension often requires a lung transplant, she next created a division of her drug company that focuses on developing artificial and transplant-able lungs from pig genetics.
But the helicopters that deliver those artificial lungs are loud and not particularly environmentally friendly, so Rothblatt decided it was time to invent the first full-size battery-powered electric helicopter to deliver the transplant-able organs more cleanly and quietly. Helicopters can burn 500 pounds of aviation fuel every hour, leaving a trail of carbon emissions in their wake. Continue reading An Electric Helicopter Arrives

Proton-exchange Membrane Fuel Cells (PEMFCs) are considered a valuable alternative energy technology capable of efficiently generating clean power. If these kinds of fuel cells can be made smaller and more cost-effective, they could potentially replace Li-ion batteries.
Scientists at Liverpool University have figured out a way to more efficiently transport proton charges in PEMFCs with the potential to make fuel cells a commercially viable energy option.
A fuel cell converts hydrogen and oxygen into water. Therefore, a fuel cell is an electrochemical energy conversion device that produces power, water, and heat as byproducts. Continue reading Fuel Cell Breakthrough may Replace Car Batteries
