Manta, the underwater kite that generates electricity from the tides
The concept of an underwater kite captures (or rather: lets itself be captured by) the waves and produces electricity in a sustainable and effective way.

Electricity changed the world: superconductors will change it again
Superconductors can really change the history of energy. Many problems have been solved: here is the step needed to reach the finish line.
OMIT, the handheld vacuum cleaner without electricity
A designer creates a "back to the future": a handheld vacuum cleaner that works without electricity. Energy saving and efficiency.
Airgel inspired by camel hair cools without electricity
A special airgel “sandwich” that mimics camel hair can cool and keep food and medicines fresh without using electricity.
Tasmania claims to be powered 100% by renewable electricity
Tasmania is the first Australian state (and one of the few) in the world to be powered by more than 100% renewable electricity. And it doesn't stop there.
AuREUS, solar windows that capture UV rays and convert them into electricity
Solar panels obtained from agricultural waste, which convert UV rays into electricity: AuREUS is a big hit for energy and environmental sustainability.
IEA: renewables will be the largest source of electricity within 5 years
The new report from the IEA, the International Energy Agency, goes beyond its most optimistic predictions
Scientists create a jet engine powered only by electricity
The prototype works, and reproduces (on a very small scale) the dynamics of a jet engine. A road opens for green flights
New spintronic circuits don't need electricity to make calculations
A new computer architecture created at MIT could lead to the advent of spintronic circuits and wave computing in the future.
Cooling without electricity: the airgel "fridge" is born
The device is based on a layer of material that blocks the sun's rays and disperses the heat away allowing it to cool without electricity.
Janus, “two-faced” membrane that obtains electricity from salt water
Named after the Roman God of passages and gates, the Janus membrane uses osmosis to produce electricity with similar efficiency to wind and solar
PureFlame, camping stove that transforms fire into electricity
A sprig, a pine cone, a log of wood: camping is technological if you can cook and even feed the devices with a fire. Here is PureFlame
Glowee, bio light and no electricity
Glowee creates biological light without electricity: it means less pollution from nuclear and coal, it means reduced environmental impact with natural substances.
Capturing energy from the wifi and converting it into electricity: a first device made
Along the road that leads to wireless electricity, or "witricity", there is an important new travel companion: a circuit developed by researchers at Duke University capable of capturing energy from sound and the WiFi signal with an efficiency close to that of solar cells. It is a small device that uses 5 copper and glass fiber conductors connected in a circuit through 5 channels made with a metamaterial. The circuit 'captures' energy from the aforementioned sources converting it into electrical energy... Read more
Within three years wireless electricity on the market
That immense, gigantic genius that was Nikola Tesla built a tower, the Wardenclyffe Tower, in the middle of Long Island: an installation, he said, capable of transmitting electricity without the need for wires. The project (with the associated mysterious fire) foundered among a thousand mysteries even though Tesla had already transmitted remote energy in other experiments, and since then the project was shelved. More than a century later it's still a big hunt: big companies (Toyota, Intel, Samsung, Foxconn) and small startups (WiTricity, ProxybyPower) have... Read more
Urine produces electricity: in 36 years I have squandered a fortune.
And I'm only counting humans: until yesterday it was considered an unpleasant waste product (except for diehard lovers of the drink). Today a team of English scientists has discovered a possible and very useful application that would help transform urine into electricity. Dr Ioannis Ieropoulos and his team at the University of Bristol last week published the surprising results of a study demonstrating how urine can be successfully used in microbiological fuel cells. … Read more
Energy from CO2: does a nanogenerator make pollution a resource?
A team from the University of Queensland has developed a revolutionary nanogenerator that absorbs CO2 to produce electricity, demonstrating how we can turn it from a problem into a resource.
Turn2Sun, high altitude sun and wind in the Swiss Alps
Turn2Sun gives wind turbines a second life by integrating them into solar systems in the Swiss Alps. Innovation at the service of the environment.
The future of urban heating: 90 GWh underground caverns
A 90 GWh underground plant is being built in Finland that will store thermal energy: heating a city for an entire year.
Bitte schön, Germany (re)shuts down 15 coal-fired power plants. And no?
Kept in operation during the energy crisis caused by the war in Ukraine, the newly closed coal plants are considered superfluous
Wind of news on solar panels: they are now self-cleaning
Rub, blow, clean, repeat. It is the dance of the wind and self-cleaning solar panels for record energy yield.
