'Fuel battery' could take cars beyond petrol

A new approach to storing electrical energy can store more energy than
gasoline in the same volume, and could help extend the range of electric
vehicles. But some experts say other approaches are more practical.

The biggest technological hurdle facing electric vehicles is their range.
Even the best rechargeable batteries cannot match the density of energy
stored in a fuel tank.

Combining electric power with a combustion engine to make a hybrid electric
vehicle sidesteps that problem. But a new take on electrical power storage
that is part battery, part chemical fuel cell could ditch gasoline for good.

The new design stores energy more densely than petrol, and was conceived by
Stuart Licht of the University of Massachusetts, Boston, and colleagues.

This needs to be re-figured. The energy stored in the fuel tank is off-
set by the total energy needed to put it there. This is outside the realm
of pure physical science.

This is a valid argument, though up to some point there has to be
assumed a "free lunch". For instance the sources of oil vary :
solar energy, primordial presence, etc. Then the sources of the fuel
battery materials also very. However, considering the direct
cost to human culture is mostly a physical science issue.
The same issues occur in nuclear power, even the portability
issues. The whole thing does need reconsideration, but the
bottom line at this time is the added flexibility in having a
working method added to our tools.
