Steam-Powered Vehicle Goes For Land Speed Record
Tuesday, December 28th, 2004
British design engineer Glynne Bowsher and his team has nearly completed their technologically advance steam-powered automobile. Their hopes is to smash the land speed record in the British Steam Car Challenge (BSCC). Not only that, they are hoping hat the vehicle in turn will spur the general public’s interest in cleanly powered vehicles.
Fuels which do not “rot” the environment usually bring to mind images of gently humming electric cars, clean hydrogen, natural gas, or hithane - a concoction of hydrogen and methane.
The most promising, believes Mr Bowsher, is either nuclear or hydrogen fuel.
The public is reluctant to explore nuclear; but researchers and engineers across the world are exploring how best to generate and, more importantly, store hydrogen fuel, one of the main barriers to its widespread use.
Nine European cities are taking part in a pilot scheme to use hydrogen fuelled buses on certain routes, for instance.
But until a viable mass-scale way of storing and distributing hydrogen effectively is developed, it remains limited in use.
Mr Bowsher believes that until then, designers could look to Inspiration for a different take on good old steam.
The key to its potential is the difference between internal and external combustion technologies.
External combustion engines - like steam ones - hold several advantages over internal ones.
They have the potential to produce fewer harmful nitrogen oxides (NOx) than conventional cars which use internal combustion engines.
Although steam engines still need to burn hydrocarbon-based fuels like petrol and diesel, which in turn release carbon dioxide, external combustion engines can control the release and the production of CO2 more efficiently.
And because such engines can work well at lower peak temperatures and pressures, the creation of NOx compounds can be almost negligible.
Current performance metrics are; Performance: Maximum speed 200+ mph (320km/h); Initial acceleration: 0.52G. The current record stands at 763 mph, or Mach 1.02, set by Andy Green in the Thrust SSC II, in 1997. Bowsher’s design will have to nearly quadruple its maximum speed in order to break the record. I suppose he is a good candidate to do it for he worked on the Thrust SSC II and designed the Thrust SSC that set the land speed record in 1983 at 633 mph. Bowsher has designed his vehicle from the ground up.
