You may not know Dean Kamen by name or by sight but you’ve undoubtedly seen the invention that rocketed him to stardom on TV, in movies, and maybe even in person. It’s called a Segway. Kamen is back with a new invention, this one without wheels.
Kamen’s latest brain-child, called “Slingshot” after the fabled weapon used by David to tackle the monstrous Goliath, takes dirty river water, ocean water and even raw sewage and turns it into pure drinking water without the energy and tons of machinery required to clean dirty water under conventional means.

San Jose is about to jump on board with the ban of the plastic single-use bag. But the city goes a step further in trying to ban the paper bag too.

San Jose’s ban would allow paper bags made with 40 percent recycled materials, but only for a fee. Yes, just another way to fee us to death – as if San Jose isn’t already outrageously expensive to live (I know, I’m from there). Read more…
