Demand for Solar Power Continues to Grow
Despite the failure of Solyndra and the relatively small sector of people who still deny global climate change, demand for solar power continues to grow. Solar is inexpensive, clean renewable energy, and is poised to overtake dirty sources of power, li…
Ray Kurzweil: Highly Sophisticated Crackpot or Scientific Visionary?
If you listen to Ray Kurzweil, you’ll believe that we’ll soon get to the point that we can live hundreds of years, power the world completely with solar energy, have computers in our brains and possibly raise the dead… and that’s just what he
Solar Sails Fly From Science Fiction Into Reality

Solar Storms Could Be Earth’s Next Katrina
Every few decades, the sun experiences a particularly large storm that can release as much energy as 1 billion hydrogen bombs. Officials from Europe and the U.S. say an event like that could leave millions on Earth without electricity, running water and phone service.
5 Sources of Alternative Energy You May Not Have Heard Of

Sun Oddly Quiet — Hints at Next “Little Ice Age”?
The sun continues to be the most sluggish it’s been in decades, prompting concerns about a cooling effect on climate–but don’t count on the dip in solar activity to fight global warming, researchers say.
The Moon Is Wet!
After several decades of controversy, scientists now know that over billions of years, water from who knows where–impacting comets or perhaps the solar wind–can collect in some of the coldest places in the solar system.
2G Now vs. 7500G Needed —> Renewables Alone = Not Enough
Posted by admin in General Sciences on August 20, 2009
To meet carbon reduction goals we would need 3500+ times our current solar output in 25 years. “The point is this: after decades of installing renewable power, we are nowhere close to making a small dent in the problem. In other words, if we think we are going to make the goal from solar, wind, & other renewables alone, we must be smoking something
