With lithium-containing batteries facing constraints on many of the metals they contain, Nina Notman looks at whether its group 1 neighbour sodium can supply the answer.

The lithium-ion battery powers much of our modern lives, a fact reflected in this year’s Nobel prize. It resides in devices ranging from very small wearable electronics, through mobile phones and laptops, to electric vehicles and ‘the world’s biggest battery’ – the huge 100MW/129MWh Tesla battery installed on an Australian wind farm in 2017.

‘Lithium-ion has a massive span of applications,’ explains Jonathan Knott, an energy storage researcher at the University of Wollongong in Australia. ‘It is being used as a hammer to crack every nut and we need to start getting a little bit more sophisticated in the use of the best tool for the job.’

A recent research study conducted by City, University of London’s Professor Christoph Bruecker and his team has revealed how micro-structured finlets on owl feathers enable silent flight and may show the way forward in reducing aircraft noise in future.

Professor bruecker is city’s royal academy of engineering research chair in nature-inspired sensing and flow control for sustainable transport and sir richard olver BAE systems chair for aeronautical engineering.

His team have published their discoveries in the Institute of Physics journal, Bioinspiration and Biomimetics in a paper titled ‘Flow turning effect and laminar control by the 3D curvature of leading edge serrations from owl wing.’

It seems the rise of hydrogen as the clean fuel for the future is coming closer to reality.

A viable substitute for fossil fuels, hydrogen has been struggling to gain traction for years — but thanks to Europe, that could soon change.

Semi-autonomous driving systems continue to come under the microscope, and the results are mixed. Tesla’s Autopilot system is one of the more well-known examples, and while some drivers like this Model 3 owner have faith in the technology, we have seen some disturbing instances of the system potentially leading to serious crashes.

Well, yet another Tesla was involved in a nasty crash and is a reminder that humans and driving aids don’t always make a safe combination. The video — recorded by the car’s camera system — was shared by GreenTheOnly on Twitter, a hacker who has previously uncovered some of the shortcomings of Tesla’s in-car tech. It’s not known what Tesla model this was.

Bill Gates recently got to check out the Omniprocessor, an ingenious machine designed and built by Janicki Bioenergy, which turns human waste into water and electricity.

With electric vehicles such as the Tesla or the Leaf being all the rage and joined by fresh competitors seemingly every week, it seems the world is going crazy for the electric motor over their internal combustion engines. There’s another sector to electric traction that rarely hits the headlines though, that of converting existing IC cars to EVs by retrofitting a motor. The engineering involved can be considerable and differs for every car, so we’re interested to see an offering for the classic Mini from the British company Swindon Powertrain that may be the first of many affordable pre-engineered conversion kits for popular models.

The kit takes their HPD crate EV motor that we covered earlier in the year, and mates it with a Mini front subframe. Brackets and CV joints engineered for the kit to drop straight into the Mini. The differential appears to be offset to the right rather than the central position of the original so we’re curious about the claim of using the Mini’s own driveshafts, but that’s hardly an issue that should tax anyone prepared to take on such a task. They can also supply all the rest of the parts for a turnkey conversion, making for what will probably be one of the most fun-to-drive EVs possible.

The classic Mini is now a sought-after machine long past its days of being dirt-cheap old-wreck motoring for the masses, so the price of the kit should be viewed in the light of a good example now costing more than some new cars. We expect this kit to have most appeal in the professional and semi-professional market rather than the budget end of home conversions, but it’s still noteworthy because it is a likely sign of what is to come. We look forward to pre-engineered subframes becoming a staple of EV conversions at all levels. The same has happened with other popular engine upgrades, and no doubt some conversions featuring them will make their way to the pages of Hackaday.

Although many different approaches have been proposed to address this problem, it’s clear that any sustainable, long-term solution will include one important component: a transition to energy sources that don’t result in additional carbon dioxide emissions. While most of the ideas put forth — such as the hypothetical Green New Deal — focus on renewable energy sources like solar and wind power, there’s another option that we should seriously reconsider: nuclear fission power.

As we embrace green solutions, nuclear should absolutely be part of the equation.

It was recently shared that yellow Tesla Model 3 taxis have started rolling out in New York City, a year after they were officially approved for taxi service in the city.

The UN population forecast predicts that by 2050 there will be almost 10 billion people on the planet. They’ll live mostly in cities and have an older median age than the current global population. One looming questions is, what will they eat?

The Green Revolution of the 1960s used selective breeding to double crop yields of rice and wheat in some areas of the world, rescuing millions of people from food shortages and even famine. Now, the fast-growing global population combined with the impact of climate change on our ability to produce food—increased droughts and extreme weather events many crops can’t withstand—points to the need for another green revolution.

Luckily there’s already one underway. It’s more decentralized than the last, which makes sense given there are different challenges surfacing in different parts of the world. A Norwegian startup called Desert Control has a running start on solving a problem that’s only likely to get worse with time.
