A new lithium-air battery created by researchers at the University of Cambridge points the way to the ultimate battery packs of the future, its makers say. With a very high energy density, more than 90 percent efficiency and the capability for more than 2,000 recharge cycles, the new test battery could prove an important stepping stone in the development of this essential technology.

If you’re getting tired of announcements about breakthroughs in battery technology, that’s understandable: as they’re so essential to modern life, many teams of scientists are busy working on the problem around the clock, but it’s an incredibly complex area of chemistry. Any new battery has to improve on what we already have, be safe to use in consumer gadgets, and be commercially viable enough to be affordable for manufacturers.

Those are difficult targets to hit, and that’s why many ‘miracle’ batteries have since fallen by the wayside – once the initial lab work is done, proving concepts and scaling up production is very difficult to get right. The potential rewards are huge though, not just for smartphones but for electric cars and solar power, where batteries are essential for storing energy to use when the sun isn’t shining.

It almost sounds like a dream: a new kind of hypersonic space-kissing jet that can take you anywhere in the world in just four hours. But the Skylon super plane being developed by UK aerospace firm Reaction Engines is very real.

The project took a big step forward this week with Reaction Engines announcing a new partnership with defence and aerospace giant BAE Systems, whose financial backing, along with a considerable investment from the UK government, will help Reaction develop its new class of aerospace engine dubbed SABRE (Synergetic Air-Breathing Rocket Engine) by as early as 2020, with test flights possible just five years later.

It’s thanks to the SABRE engine that the Skylon could theoretically take you to the other side of the planet for lunch, before dropping you safely back home in time for dinner.

The local delivery market is worth approximately £150bn in the UK alone. This includes parcel and delivery companies (20 pc) and personal shopping trips by people (80 pc). Starship said that robot deliveries are potentially five to fifteen times cheaper than current “human-powered” delivery services.

“It does not take the whole delivery chain from an Amazon warehouse to your doorstep, it only takes the last few miles. But right now the last few miles are the most difficult part for the delivery vans. They need to find parking spaces and so forth, so our robot is taking care of that,” said Mr Heinla.

“For the large e-commerce companies it helps to reduce the costs. For the local businesses it opens up new possibilities, allowing people to order deliveries over the internet rather than coming to the store physically.”

To critics, it’s flat-out junk science, not even worth thinking about. But its inventor, Roger Shawyer, has doggedly continued his work. As Danger Room reported last year, Chinese scientists claimed to validate his math and were building their own version.

Shawyer gave a presentation earlier this week on the Emdrive’s progress at the CEAS 2009 European Air & Space Conference. It answered few questions, but hinted at how the Emdrive might transform spaceflight — and warfare. If the technology works, that is.

The heart of the Emdrive is a resonant, tapered cavity filled with microwaves. According to Shawyer, a relativistic effect generates a net thrust, an effect confirmed by various Emdrives he has built as demonstrations. Critics say that any thrust from the drive must come from another source. Shawyer is adamant that the measured thrust is not caused by other factors.

A Canadian engineer has come up with a new concept for a four-winged scramjet that could carry 75 passengers at speeds of up to Mach 10 — which is 10 times the speed of sound and five times faster than Concorde. That means the proposed Skreemr jet could cross the Atlantic in just half an hour.

Unfortunately, the design is purely conceptual and the designers admit that it’s unlikely to ever be realised, due to the current limitations of scramjet technology. But it’s still a pretty cool glimpse into what we could one day achieve with air travel.

As most science lovers will know, scramjet systems work by combusting liquid using oxygen taken from the atmosphere passing through the aircraft. This means that, unlike traditional propulsion systems, the craft doesn’t need to carry any liquid oxygen, so the whole thing becomes a lot lighter, and therefore faster.

During the press conference for the release of the Autopilot, Tesla CEO Elon Musk referred to each Model S owners as “expert trainers” – meaning that each driver will train the autonomous features of the system to feed the collective network intelligence of the fleet by simply driving the electric vehicle on Autopilot.

He said that the system should improve everyday, but that improvements might only become noticeable every week or so by adding up. Just a few weeks after the release, Model S owners are already taking to the Tesla Motors Club forum to describe how the Autopilot is improving…

Nissan says its autonomous car will be ready for sale to consumers by 2020.

Nissan Motor Co. is aggressively pushing forward with plans for a mostly autonomous car that will be ready for sale to consumers by 2020, putting it well ahead of its global competitors.

Chief Executive Carlos Ghosn said the technology would be ready by the Japanese auto maker’s self-imposed deadline—though he wasn’t sure if it would be legal on any nation’s roads.

At the Tokyo Motor Show 2015, Nissan unveiled a concept vehicle that embodies Nissan’s vision of the future of autonomous driving and zero emission EVs: the Nissan IDS Concept.

Presenting at the show, Nissan president and CEO Carlos Ghosn said: “Nissan’s forthcoming technologies will revolutionize the relationship between car and driver, and future mobility.”
