Riding the electric bus... sounds bunches safer than drafting behind it.

I forget just how long it was that people flew in airplanes... before someone created a parachute. It isn't at all surprising... if we look at history... that we invented numerous ways to use energy before we invented cheap pollution free-ish energy. Even as people erect windmills and experiment with new ways to construct batteries.... progress on fusion power has continued to plot along.

The vast human inventiveness, creativity, and worry that went into replacing animal power little more than a century ago... vastly improved human lifestyles. And even helped progress the safety bicycle. Whether we fret or not... technical progress will transform energy production completely. Todays ways of producing power is very temporary. This isn't how it was done a century ago.... and it won't be done this way a century from now.

You have to break a few eggs... to make an omelet. Right now... energy-wise we are still in the broken eggs stage. If you look to the universe you know that energy is plentiful. Mankind will master the atom. Or we will follow our predecessors into extinction.
