One of the best thing about electric and hybrid vehicles is that the energy doesn’t get completely wasted when you need to brake. By using an electric motor as a generator, you can slow a vehicle down and put some of that kinetic energy into a battery pack so you can use it again later. Sure, there are conversion losses both going into the battery and coming back out to the wheels, so you don’t get a lot more than half of the energy back, but an ICE vehicle turns all of that energy into heat, which gets dissipated into the air.

Electric bikes, scooters, and other micromobility options can do regenerative braking, too. This is great for getting better range and doing fewer brake jobs, just like in a car.

A superthin electrolyte with three layers could deliver safe, fast-charging batteries.

These self-powered robots, which were inspired by water-walking insects, delivered chemicals while partially submerged in a solution.

British Lithium explains their pilot method of lithium extraction at its pilot plant, which was built over seven months and funded by government innovation agency Innovate UK:

Our unique pilot plant approach incorporates all processing stages – from quarrying through to high purity lithium carbonate production. This includes crushing, grinding, and beneficiating the ore, custom-built electric calcination at low temperatures, acid-free leaching, and multiple purification steps that include ion-exchange.

The company will manufacture 5 kilograms (11 pounds) of lithium carbonate per day from early 2022 in its pilot plant, which it says is enough to demonstrate its commercial value to customers. Once the process is fully developed, British Lithium will begin work on building a full-scale plant.

An artificial intelligence (AI) system that can identify diabetic retinopathy (DR) without physician assistance, including the most serious form that puts patients at risk of blindness, has outperformed expectations in a clinical trial. The commercial system successfully detected the presence and severity of the disease in 97% of eyes analysed. Deployment of such AI systems in primary care facilities for use by non-specialists could significantly increase access to eye exams that include DR evaluation, aiding in the diagnosis and treatment of the disease.

An artificial intelligence system that simplifies diabetes retinal screening could help save the vision of millions of people around the world.
