abstract:Mindflex was a toy by Mattel which apparently used brain waves to steer a ball through an obstacle course. The brain waves are captured with the enclosed EEG headset, which allows the user to speed up or slow down a fan, thus lifting or lowering the blue styrofoam ball.
When life-cycle costs are compared, natural gas is currently a more economical decision than flex-fuel powered vehicles, although both are more expensive than gasoline at current figures (keep in mind that these dynamics could change due to oil shocks or increased demand for traditional fuels both real risks).
