A startup has come up with a stronger EV battery without the precious metals
Creating long-range electric vehicles that are still comparable in affordability to gasoline cars has long been the challenge of the electric vehicle industry. While improvements in technology have made batteries cheaper and more efficient, the average addition of a battery to a vehicle still costs Read More...
The sci-fi idea of suspended animation is now buying ER surgeons more time
Nowadays, it seems things that you would only see in science fiction films are becoming a reality all the time. The latest example of sci-fi-turned-reality comes from the University of Maryland Medical Center where doctors have successfully placed humans in suspended animation for the first time. Read More...
New Jersey just doubled its offshore wind power promise
How do you go about generating renewable energy when your state has 130 miles of windy coastline? Massive wind farms, of course. This week, New Jersey Governor Phil Murphy declared the state will install 7.5 gigawatts of offshore wind by 2035, almost double its initial target of 3.5 gigawatts. Read More...
The humble ski-lift could lead us to clean energy that’s available on demand
What do you see when you imagine a zero-carbon future? Electric buses zipping by? Rolling hills covered with solar panels? Offshore wind farms towering over the sea? If batteries are part of your vision, good thinking. But there’s a promising if whimsical, piece of the renewable energy puzzle Read More...
These electric cars make a humming noise to help pedestrians - and the surrounding flora
Within the next two years, the US and Europe will require all new electric and hybrid vehicles to emit noise in order for pedestrians to hear them coming. But automakers and regulators are still not settled on what that noise should sound like. In a search for the best one, Ayax — an independent Read More...
How a tech industry trick could save the humble banana

This major airline declares it will be first to operate net-zero carbon flights
The budget airline EasyJet came out with a pretty bold statement this week, declaring that it will become the first major carrier to operate net-zero carbon flights. While that won’t be from zero-carbon technologies just yet, the airline announced it will offset all carbon emissions from the fuel Read More...
Mirror-based solar panels could finally decarbonize steel production
A typical large steel mill might burn through 1.5 million metric tons of coal in its furnaces in a year. It hasn’t been possible to run that type of industrial process on renewable energy, because of the extremely hot temperatures required, making nearly a quarter of global emissions hard to Read More...
Scientist have made an AI that predicts when and where lightning will strike
Lightning strikes may be beautiful to see, but the consequences of them can be brutal. For one, lightning kills more people each year than tornadoes or hurricanes. On top of that, lightning strikes can be detrimental to farmers as they can cause fires that can destroy millions of dollars' worth of Read More...
