The Mazda Rotary might survive big by using H2 as fuel, competing with
the fuel cell.

Comment: Could it be a higher operating pressure used with the Rotary
than possible with the
Reciprocating Engine that makes the Rotary more efficient by using H2?

Mazda to Develop Hydrogen-powered Rotary Engine

Japan's Mazda Motor Corp aims to develop a rotary-engine car powered by
hydrogen, which would
be far less costly than fuel-cell cars and more environment-friendly
than gasoline vehicles, a report said
Wednesday.

The nation's fifth-ranked automaker will unveil a prototype car at the
Tokyo Motor Show in October,
aiming to put it on the market in some five years, the Nihon Keizai
Shimbun reported.

The car, with the roughly 150-horsepower engine and based on the RX-8
sports car, would be able
to run about 200 kilometres (125 miles) on a single tank of fuel, the
economic daily said.

Rotary engines are less fuel-efficient than internal combustion engines
when running on gasoline, but
are expected to be more efficient than standard engines when powered by
hydrogen, it said.

It would cost three million to four million yen ($25,200 to $33,600) to
build a car mounted with the
hydrogen-powered rotary engine, it said. (AFP)

This sounds like another crock full from the eco idiots. There is nothing
about
hydrogen that would increase the thermal efficiency of the rotary or any
other
combustion engine. The only thing hydrogen has a chance with is a fuel cell
where the increased conversion efficiency would still not make up for the
cost of hydrogen and the difficulty of storing useful quantities - Vance J
