  • Battery elimination, indeed elimination of all energy storage, is moving to even higher power, from electronics to electrical engineering.

  • A step towards new "beyond lithium" rechargeable batteries with superior performance has been made by researchers.

  • This year the Battery Show North America had a record 7500 visitors joined, and 500 exhibitors, including IDTechEx, were present on the exhibition floor. Lorenzo Grande reports on his experience at the show.

  • Scientists have developed a new type of ultra-thin photovoltaic device, coated on both sides with stretchable and waterproof films, which can continue to provide electricity from sunlight even after being soaked in water or being stretched and compressed.

  • Energy Storage Innovations (ESI) USA 2017 is the leading conference to learn about new developments in battery technology. Organised by the technology consulting firm IDTechEx, ESI's aim is to bring together different players in the value chain.

  • All the publicity currently goes to the race to make regular and premium cars have longer range. This is because most people want only one car so it must be capable of the long distance trip however rare. That must be achieved despite the inadequacy of charging points in number, speed and compatibility of interface and payment means.

  • Researchers are looking at advanced materials for roads and pavements that could generate electricity from passing traffic.

  • Liquid Robotics has announced the next generation of the Wave Glider with advancements to the platform's operational range, and performance for missions in high sea states and high latitudes.

  • Cars must be driven out of cities to tackle the UK's air pollution crisis, not just replaced with electric vehicles, according to the UK government's top adviser talking in August 2017.

  • Researchers have shown that defects in the molecular structure of perovskites - a material which could revolutionise the solar cell industry - can be "healed" by exposing it to light and just the right amount of humidity.

  • New Zealand leads the world in zero emission renewable grid electricity now at 85%. With a nice balance between geothermal, hydroelectric, unusually continuous wind power and some solar, the country has less intermittency of green power than most.

  • The vending carts harness the energy of the sun and the company have created a holistic solar system whereby a vendor makes small daily payments for the cart, activating the solar panel.

  • Chemists have published the first techno-economic analysis of converting waste toilet paper into electricity.

  • As the world's first conference on Energy Independent Electric Vehicles approaches on September 27-28 in the Technical University of Delft Netherlands, key players, all of whom are speaking at the event, have been announcing some remarkable new developments.

  • No, not what you thought. Japan has very dirty power generation with renewables stuck at around 10% for two decades then rising last year to approach 15%. New Zealand has now powered up from 80 to 85% renewables feeding its grid - around the figures of Iceland and Norway.
