Perspectives: Unpacking the hydrogen color codes
You may have heard the terms brown hydrogen, grey hydrogen, blue hydrogen, and green hydrogen when referring to this energy source. Who knew hydrogen, the most abundant element in the universe (76 percent of all molecules in the universe are hydrogen), came in so many colors! Actually, it Read More...
POWERPASTE could make hydrogen fuel technologies safer and more efficient
While hydrogen fuel cells have a huge potential to shift our transportation industry towards a cleaner future, one of the main reasons why the technology hasn’t yet reached scale is because hydrogen is incredibly volatile and challenging to store and transport. In a bid to overcome this Read More...
Medical drone delivery project to service remote communities in Uganda
Advancements in modern medicine allow for multitudes of medical problems to be managed by the individuals who live with them, but what good are these advancements to those living in remote areas if they aren’t accessible? Ensuring that remote communities have equitable access to modern Read More...
Wind turbines on a vertical axis can boost efficiency of wind farms
According to the latest Global Wind Report, the world needs to triple its wind energy production over the coming decade in order to reach critical net-zero targets. While that’s a very ambitious goal, a new study demonstrates that by redesigning conventional wind turbines, we could boost their Read More...

The Manta will be an Read More...
E-waste: Scientists develop the world’s first fully recyclable transistor
One of the main reasons why so many electronics end up as e-waste instead of getting recycled at the end of their life is the fact that it’s really difficult to separate and recover the valuable materials that make them up. Now, a new technique developed by scientists at Duke University may help Read More...
This underwater kite generates electricity using water currents
Some time ago, we introduced you to KiteKraft, an innovative kite design that uses the power of the wind to generate clean electricity. Now, a similar kite system aims to do the same, but by using tidal and river currents instead. Called Manta, the system was developed by scientists at the Read More...
