August 21, 2015 - If we could directly harvest carbon dioxide (CO2) from the air and separate and capture the carbon while converting what's left to oxygen then that would really be a technology breakthrough of consequence in our fight against global warming. Sounds like science fiction? Well it's not.
August 19, 2015 - I am often asked by readers if it is worth putting solar panels on the roof of their homes. Here in Toronto solar powered houses are few and far between. But just because Toronto is in a northern country doesn't mean solar power is not a good alternative to grid-delivered electricity.
August 18, 2015 - It goes by the acronym SALt. It is the invention of a brother and sister from the Philippines. And it is an answer to a long enduring problem in the Developing World, providing light after dark when you have no access to power from a local or national grid.
August 16, 2015 - When my wife and I were in Florida last winter we drove along A1A, the roadway next to the Atlantic Ocean, where the City of Fort Lauderdale was in the process of spending $11.8 million to mitigate against future hurricanes and "storms of the century"
August 12, 2015 - The promise of an affordable commercial fusion reactor continues to be ten years out. It was ten years out in 1990. Ten years out in 2000. And ten years out in 2010. There is pattern here. The promise of fusion is constantly receding into the future.
August 9, 2015 - Kiwi country announced this week that their remaining two coal-fired power plants will be shut down as of 2018. Now one cannot compare the carbon emissions of New Zealand with those of the United States, China, or even Australia, New Zealand's nearest neighbour, but decommissioning coal-generated energy sources even in two plants cannot hurt.
August 8, 2015 - The move away from burning carbon to create energy is being inhibited not by the explosive growth in renewables but by the current state of battery technology. That's because energy storage is the other half of the renewable equation.
August 7, 2015 - One trillion is a big number. And when it comes to carbon dioxide emissions it represents what scientists believe is the absolute limit of that gas in our atmosphere. One trillion translates to a peak of 450 parts per million (ppm).
August 6, 2015 - Celebrating the 400th anniversary of the Pilgrims' voyage to America in the original Mayflower, the Marine Institute and School of Marine Science and Engineering, at Britain's Plymouth University, intend to build and launch a full-sized autonomous ship powered by renewable energy to cross the Atlantic Ocean in 2020.
August 5, 2015 - Graphene is seen as a material that is altering our technical world. But it isn't alone. In the past few weeks two others have joined the new materials world of electronics. One is gallium nitride (GaN), and the other is sol-gel.
