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.

Unlike the United States which has chosen to rest on its Apollo Program laurels, Russia is reviving the Soviet dream to establish a permanent human presence on the Moon. The United States, however, has made it quite clear that it has no plans to return to the Moon unless it does it conjointly with other partners.

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.

April 10, 2014 - Using agricultural land to grow an industrial crop to convert to fuel seems like a make work project for farmers. Yet an entire subsidized industry has grown up in Brazil, the United States, Canada and other countries doing just that. In Brazil they turn sugar cane into ethanol (which I don't mind too much since sugar in my book is more a food additive than a food).

The security industry will face the same digital tornado as music, news and cameras. When security is turned into embedded features our homes, businesses, vehicles and property will recognize their owners, authorized users, and uses. They will also track their own location, record unauthorized activities, and more. Self-controlled security will first be transforming, then world changing.
