A startup has a grand vision to make hydrogen trucks a reality by 2020
The hydrogen-powered-vehicle industry is still a nascent field that has yet to show real signs of going mainstream. Yet, major automakers are exploring the technology because it gives vehicles shorter re-fill times and longer ranges than plug-in electric vehicles. General Motors and Honda, for Read More...
Texas has become the unlikely champion of wind energy in America
The most Republican-dominated, oil-rich and fracking-friendly of the U.S. has found itself with the improbable status of being a national leader of wind energy. That’s right, Texas has by far the greatest wind generating capacity in the entire U.S., producing enough electricity to power 5.7 Read More...
Learning to market digital trust could be the economic boom Africa needs

The Uber effect on electricity
Leon Trotsky said, "You may not be interested in war, but war is interested in you." The same thing might be said about disruptive technologies. The U.S. electric system, for example, may not be interested in disruptive technology, but disruptive technology is interested in it. What Uber and Lyft Read More...
Ultrafast camera to improve vision of self-driving cars and drones
To avoid accidents, self-driving cars and drones need to be able to quickly take in their surroundings even in extreme road conditions and bad weather, but conventional optical cameras aren't quite up to the job. To improve the vision of such vehicles, a team of engineers at the Nanyang Read More...
We need slow science to sow the seeds of future prosperity
A scientist's work is never done. They build on the work of others, and leave their own work for others to build on. Scientific progress is a bit like a tree with deepening roots and growing branches – which sometimes take a long time to bear fruit. Consider “bootstrap” research, Read More...
Bill Gates: The robot that takes your job should pay taxes
As artificial intelligence continues to advance, it's only a matter of time until robots start taking human jobs.

But it's much cheaper to train Read More...
New interactive tool shows ‘the evolution of wind power’ around the world
A new interactive web tool created between the Global Wind Energy Council and renewable energy software company Greenbyte allows users to witness The Evolution of Wind Power between 1981 and today. The Evolution of Wind Power was created based on data provided by the Global Wind Energy Council Read More...
