The Last Human – A Glimpse Into The Far Future.

German animation and design studio, Kurzgesagt, explores the far future of humanity and how our population may change over the aeons.

Given the numerous global threats we face during this century and beyond – from climate change to nuclear war, asteroid impacts and killer viruses – many of us are concerned that humans could go extinct. But there are reasons to be optimistic, according to this latest video from Kurzgesagt. Rather than approaching the end of human history, we may actually be living at the dawn of our species; the mere prelude for a vast and exciting future that lies ahead.

Way too many batteries still end up in a landfill, though it depends on the type. While 90% of lead acid batteries are recycled, experts estimate that only about 5% of lithium-ion batteries currently enter a recycling stream. Many more lurk in drawers or end up in the trash. That’s a problem.

Why you shouldn’t throw batteries in the trash

Lithium-ion batteries can cause fires when exposed to heat, mechanical stress, or other waste materials. Once exposed, the elements contained in the batteries could leach into the environment and contaminate the soil and groundwater. While this shouldn’t present an issue at a well-managed domestic facility, exported trash might end up at a more lenient landfill. Richa et al. note that “the greater risk is loss of valuable materials.”

Scientists in Germany looked to eliminate the use of toxic solvents in the production of perovskite solar cells, replacing them with a more environmentally material called dimethyl sulfoxide (DMSO) which has so far proved difficult to integrate into processes suitable for large-scale production. The group demonstrated a scalable blade coating process using DMSO as the only solvent, and reached cell efficiencies close to those achieved using more toxic substances.

MS Tûranor PlanetSolar, also known as PlanetSolar and founded by Swiss explorer Raphael Domjan, is the world’s largest solar-powered boat, which was launched on March 31, 2010. Between 2010 and 2012, it became the first solar electric car to round the globe, taking 584 days.

Solar panels covering 537 m2 of the 31-meter boat, rated at 93 kW, connect to two electric motors, one in each hull. The ship’s two hulls contain 8.5 tons of lithium-ion batteries. Because of its shape, the boat can go at speeds of up to 10 knots (19 km/h). To establish its hydrodynamics and aerodynamics, the hull was model tested in wind tunnels and tank tested. After the record attempt, the boat was planned to be utilized as a luxury yacht.

By Subscription? – In California, You Can and it’s a Tesla Model 3 EV.

A Santa Monica, California-based company can put you into a Tesla Model 3 using its cellphone app which is now available for both Android and iPhones. The company offering the Car-as-a-service (CaaS) model is Autonomy. Although currently available only in California, the future plans include rolling it out to other U.S. states.

Until the outset of the global pandemic, owning a car was on a dramatic decline. Ride-sharing was exploding, and because cars were becoming pricier, young people entering the workforce were less inclined to join their parents’ generation of car owners.

Isolation and lockdowns temporarily took drivers off the road, as did sticker shock. The latter has been particularly true for electric vehicles (EV) which without government rebates and incentives can cost tens of thousands of dollars more than cars running on gasoline and diesel.

For his work on liquid metal batteries that could enable the long-term storage of renewable energy, MIT Professor Donald Sadoway has won the 2022 European Inventor Award, in the category for Non-European Patent Office Countries.

Sadoway is a longtime supporter and friend of MIT’s Materials Research Laboratory and is the John F. Elliott Professor of Materials Chemistry in MIT’s Department of Materials Science and Engineering.

“By enabling the large-scale storage of renewable energy, Donald Sadoway’s invention is a huge step towards the deployment of carbon-free electricity generation,” says António Campinos, President of the European Patent Office. “He has spent his career studying electrochemistry and has transformed this expertise into an invention that represents a huge step forward in the transition to green energy.”
