Censorship, Windows Phone RIP, UK green strategy and more: the week’s top tech news

Jonathan Wilson, online managing editor Online censorship: who are the gatekeepers of our digital lives? Social media censorship: filtering out extremist content Well, that’s it. The dream of a free and uncensored internet, where all content was equal and equally available, is dead.…

Researchers make headway in desalination technology

Engineers at the University of Illinois have taken a step forward in developing a saltwater desalination process that is potentially cheaper than reverse osmosis and borrows from battery technology. In their study, the researchers are focusing on new materials that could make desalination…

Low-cost ‘breathing’ battery could solve renewable energy storage problem

The research team believes the battery is ideal for storing electricity produced from wind and solar sources so that the grid can still be powered when they are not generating. The ‘air-breathing’ battery is capable of storing electricity for very long durations for…

Researchers pursue low-cost, efficient technologies for hydrogen generation

While hydrogen is often talked about as a pollution-free fuel of the future, especially for use in fuel cell electric vehicles, hydrogen can be used for much more than zero-emission cars. In fact, from enhancing the flexibility of the grid to greening agriculture,…

Researchers mimic two natural energy processes with a single catalyst

Nature is quite good at doing certain kinds of chemistry. For example, water is continuously transformed into its constituents, oxygen, protons, and electrons, and back again as a way of storing and using energy by plants and animals. Technologies based on natural chemical…

Japanese, Chinese Secondary Battery Makers Threatening Korea Rivals

Secondary Battery RaceAccording to market research firm SNE Research, Panasonic reached 4,974.9 MWh in shipments of secondary batteries for use in electric vehicles for the first seven months of this year. Its market share soared to 24.9% based on its product supply to…

Organic/inorganic sulfur may be key for safe rechargeable lithium batteries

A different type of lithium sulfur battery could be more efficient, less expensive and safer. Published in: Published in: Nanowerk

Organic/inorganic sulfur may be key for safe rechargeable lithium batteries

We have come a long way from leaky sulfur-acid automobile batteries, but modern lithium batteries still have some down sides. Now a team of Penn State engineers have a different type of lithium sulfur battery that could be more efficient, less expensive and…

Low-cost battery from waste graphite

Researchers have discovered promising approaches as to how we might produce batteries out of waste graphite and scrap metal. Published in: Published in: Nanowerk

Storage is renewable energy’s greatest challenge—this low-cost sulfur battery may help

Motivated by a challenge from the Department of Energy to drastically reduce the cost of storing renewable energy on the grid while capturing more of it, a group of Massachusetts Institute of Technology scientists has developed a battery powered by sulfur, air, water,…
