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

Samsung will have graphene batteries: recharge in 15 minutes
Graphene batteries are 3 to 5 times faster than lithium-ion batteries, which take around 90 minutes to fully charge.
Aquanaut, the underwater robot transformer
To explore the seabed and manage ocean platforms, a team of NASA veterans builds a transformer underwater robot that becomes humanoid.
The hydrogen train makes its debut in the UK: how is it going elsewhere?
Even in the UK the hydrogen train starts running. How is development going in the rest of the world? Let's take stock with this article.
A ferroelectric battery improves with use
The 96-year-old inventor of lithium batteries challenges thermodynamics by announcing the development of a glass battery that increases its capacity with use rather than deteriorates.
Airvida, the wearable air purifier
Bad to say, but we live in an atmosphere that is now so aggressive and polluting that defending ourselves is a duty: while waiting for clean air to return for everyone, let's put what we need around our necks.
StoreDot recharges an electric scooter in just 5 minutes
StoreDots are thinner than normal lithium-ion batteries, contain less lithium, more Germanic and some preserving agents that counteract their decay: the results are amazing.
5 revolutions that will change energy in the next 5 years
Five years is a long time: enough for the Sun to radiate the energy equivalent to all our reserves of oil, coal and natural gas and enough for the world to revolutionize energy in at least 5 ways. Here are 5 energy revolutions that we will see between now and 2024.
The ringwatch sees the light.
We've been talking about it for some time, but recently the first semi-functioning prototypes of a digital ring-clock capable of communicating with devices have emerged. Surgical steel, patented system, three rotating rings showing hours, minutes and seconds with the help of blue or orange LED lights. The system is equipped with a wirelessly rechargeable lithium battery, which provides a full week of use on a single charge. Here are a couple more… Read more
Future car tests: no engine, transmission, differential. That's how
This car has no engine, no transmission and no differential: it weighs half of a normal car: each of its four wheels has an electric motor which allows it to contribute to the movement of the vehicle and a rapid change of direction: at current state, however, you need advanced control for the movement or it is really difficult (not to say impossible) to drive it. Junmin Wang is an assistant professor of Mechanical Engineering at Ohio State University, and his team is… Read more
Graphene prodigies: charged electric cars in 16 seconds, now you can
If I asked 10 of you readers what in your opinion is the biggest problem that hinders the large-scale diffusion of electric cars, probably 3 of you would blame the oil lobbies (it's a sin to think badly but you're not often wrong) and 7 of you would blame conventional batteries, which take too long to charge. Well, you're all right. Graphene supercapacitors, however, are a more than concrete promise to solve the problem: they are… Read more
Sodium ion batteries, studies continue with a sweet discovery.
Lithium, the main element in the composition of the batteries that power our devices (and also in the war against bipolar personality disorder) is not omnipresent on Earth: several countries are forced to import it from abroad, and this shortage leads to notable swings in the prices of technological devices: the signs of its future scarcity are already there in the ever-increasing price that quality batteries present to buyers. A group of researchers from Tokyo University led by Professor Shinichi Komaba may have… Read more
