Personalized energy systems, where instead of huge nuclear plants (or worse, even larger windmills or solar farms) powering air conditioning for homes or gas stations fueling cars, individuals can produce power themselves, edged a little closer as scientists reported discovery of a new nickel borate catalyst that could boost efficiency of fuel cells up to 20,000 percent. 

The system would consist of rooftop solar energy panels that produce electricity for heating, cooking, lighting, and to charge the batteries on the homeowners' electric cars during. Any surplus electricity would go to an 'electrolyzer, a device that breaks down ordinary water into its two components, hydrogen and oxygen. Both would be stored in tanks.
My son thinks science is cool. He loves biology.  My daughter used to like science, now she says she hates it - she hates math too. She's just started middle school. That's the age when girls walk away from science - or at least the research tells us they do.

I've been trying to figure out why my daughter - who spent the last five years in a science and math magnet - now isn't interested in either subject.
