Harnessing Jet Streams, Creating JobsLast Updated on 2012-06-19 00:00:00
Continuous upper atmosphere winds in excess of 200 mph contain 100 times the energy used yearly by humans. Innovators, engineers, atmospheric scientists and entrepreneurs believe that huge kite-like wind-power generators could easily and very affordably provide all the energy needed to power our planet.
And just imagine all the jobs that will be created.
Jet streams are quick moving upper air currents flowing continuously from west to east. Polar jet streams are stronger than subtropical jet streams, and they both occur in each hemisphere ranging in altitude from about four to 10 miles above Earth's surface.
In 1752 Benjamin Franklin -- a Founding Father, scientist, printer, inventor, author, musician, civic activist, statesman, diplomat and economist -- undertook a series of electrical experiments using a kite to prove that lightning was a stream of electrified... More »

Report: Humans near tipping point that could dramatically change EarthLast Updated on 2012-06-07 00:00:00
Human activity is affecting Earth in many ways, but a new study suggests that continued population growth and its impact on climate and ecology could trigger a more profound chain reaction of effects within little more than a decade.
The variety and distribution of plants and animals on Earth – and, for many species, prospects for survival – may be nearing an abrupt, fundamental change because of human activity, warns an international team of ecologists and biologists.
Unless humanity deals with the underlying causes that could be pushing Earth's biosphere toward such a change, the results could lead to social and economic instability, write the researchers in a study unveiled Wednesday in the journal Nature.
The underlying triggers that the researchers say could lead to a global ecological tipping point have a familiar ring: population growth and the... More »
Are We Nearing a Planetary Boundary?Last Updated on 2012-06-06 00:00:00
The earth could be nearing a point at which sweeping environmental changes, possibly including mass extinctions, would undermine human welfare, 22 prominent biologists and ecologists warned on Wednesday.
Acknowledging in a new paper that both the likelihood and timing of such a planetary “state shift” were uncertain, the scientists nonetheless described warning signs that it could arrive within a few human generations, if not sooner.
The problems are familiar by now: they include a planetary warming that, while slow on the scale of a human lifetime, is extremely rapid on a geologic time scale, the scientists said. And human population growth and economic expansion continue to demand new resources like energy and food, to claim new land and to cut natural landscapes into disconnected patchworks.
Humans have already converted about 43 percent of the ice-free... More »
