Fresh Squeeze Solar

Wednesday, June 9th, 2010

We usually have to plow deep for good news these days; here’s some just off the vine.

…[a solar power] invention that uses dye squeezed from berries. The dye acts as the chlorophyll in green leaves that allows the “Graetzel cell,” a layer of titanium dioxide nanoparticles, to absorb sunlight.

The invention is cheaper than the standard silicon photovoltaics in conventional solar power cells, making it a cheaper solution to the world’s energy problems, according to the Technology Academy of Finland.

The Graetzel cell can be used to power street lamps.

Martin Gardner: Gone

Monday, May 24th, 2010

Martin Gardner, one of the world’s quintessential men of reason, passed away at age 95 on Saturday.

… [he] teased brains with math puzzles in Scientific American for a quarter-century and … indulged his own restless curiosity by writing more than 70 books on topics as diverse as magic, philosophy and the nuances of Alice in Wonderland…

…also wrote fiction, poetry, literary and film criticism, as well as puzzle books. He was a leading voice in refuting pseudoscientific theories, from ESP to flying saucers. He was so prolific and wide-ranging in his interests that critics speculated that there just had to be more than one of him.

[In 1983]  …he began a column in Skeptical Inquirer, “Notes of a Fringe Watcher,” which he continued to write until 2002. He had already begun beating this drum, debunking psuedoscience, in his book “Fads and Fallacies in the Name of Science.” He helped found the Committee for the Scientific Investigation of Claims of the Paranormal.

In The New York Review of Books in 1982, Stephen Jay Gould, the evolutionary biologist, called Mr. Gardner “the single brightest beacon defending rationality and good science against the mysticism and anti-intellectualism that surround us.”

Avatar: The Movie

Monday, January 18th, 2010

Avatar, the technically amazing, richly conceived and executed movie, will not be to everyone’s taste.  It is tasty enough, however, to have broken all box office records, streaking to be the fastest movie to gross over $500 million, in only 32 days. Second place goes to The Dark Knight, which took 45 days, followed by Cameron’s Titanic taking 98 days.  The “you-gotta-see it” factor is enormous.  Even those who avoid big American films –including yours truly– are persuaded, and pay the 3-D marked up ticket price.

The visual richness and imaginative detail of Pandora, the moon/planet,  the setting of the entire film, is simply astounding.  The floating-in-space scenes as the humans approach their destination, unforgettable.  The merging of human/actors with humanoid/graphics is seamless, especially when both seem to be appearing in the same sequences – an actor in an attack helicopter alongside an enormous computer graphics gun ship, complete with a mad man in command and troops with guns on the loading dock.

Plastic Bag Eater

Monday, June 2nd, 2008

This is why we need the young: to do what their elders can’t imagine.

Getting ordinary plastic bags to rot away like banana peels would be an environmental dream come true.

After all, we produce 500 billion of them a year worldwide, and they take up to 1,000 years to decompose. They take up space in landfills, litter our streets and parks, pollute the ocean and kill the animals that eat them.

Now a Waterloo teenager has found a way to make plastic bags degrade faster — in three months, he figures.

Sphingomonas & Pseudomonas

One will want to know what happens to the glutted bacteria when the banquet is over but it looks promising….
