My design, you mean to say that green energy means that energy which produces less waste and causes little changes in the enviornment ?Is this energy produced by solar,wind and other alternative sources am i correct

Debera, you are right up to an extent. Green energy means less pollution, ecco friendly etc, while usage and during the process of energy generation too. In that sense, solar & wind are more ecco friendly.
Good points, RalphyBoy. Gyms do have tremendous potential for human energy to be converted to electricity. Stationary bikes, cross trainers and, yes, even dance floors could be kicking energy back into the grid.
If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
Robots in films during the 2000s hit the big time; no longer are they the sidekicks of nerdy character actors. Robots we see on the big screen in recent years include Nicole Kidman, Arnold Schwarzenegger, and Eddie Murphy. Top star of the era, Will Smith, takes a spin as a robot investigator in I, Robot. Robots (or androids or cyborgs) are fully mainstream in the 2000s.
