The Toronto-Dominion Bank, currently vying for the number one position in Canada, and a growing player in the United States, issued on April 14 a special report, Natural Catastrophes: A Canadian Economic Perspective. The document doesn't directly talk about climate change but it is inferred throughout. Instead, it talks about "weather conditions" and their socioeconomic impact.

Historically, one of the biggest challenges faced by both Soviet and U.S. space programs is related to keeping the air inside spacecraft breathable. The future of human activity in space requires a better solution. In its latest initiative, NASA, the American space agency, hopes to achieve a better recovery system for recycling oxygen that exceeds 75% recovery.

I'm a regular blood donor. My blood type is "A," "Rh+." That can tell you a lot about your origins. But what I get excited about is the promise of finding a process by which we can end blood transfusions forever, mass producing all the blood we need rather than tapping the veins of donors every 56 days to keep an adequate blood supply in hospitals and clinics around the world.

Seawater is proving to be one way to combat climate change by reducing fossil fuel dependency for some ocean island nations. Taking a page from land-based geothermal power which uses the coolness below ground in heat exchange systems, islands are using the thermal energy gradient in a column of seawater to generate electricity.

April 12, 2014 - There are two types of solar renewable technologies. The first, solar photovoltaics, is at best marginally efficient when converting energy from sunlight into electricity. And when the sun is not shining...well you get it. The second, solar thermal involves putting mirrors on motors to track sunlight.
