Brit car smashes century-old speed record, clocking 225
kph
London:
A British-built car has broken the land speed record
for steam-powered cars for the first time in more than
100 years, after it achieved an average speed of 225 kilometres
per hour. According to a report in New Scientist, Charles
Burnett III has reached speeds of 219 km/hr (136 mph)
and 243 km/hr (151 mph) during two drives at California's
Edwards Air Force Base. That smashes the previous official
record of 204 km/hr (127 mph) set in 1906 by Fred Marriott
of the US in a modified version of the then-popular steam
car known as the Stanley Steamer. Officials from motor
sport's governing body, the Federation Internationale
de l'Automobile (FIA), are expected to ratify the new
record shortly. Burnett drove a 7.6-metre-long, 3-tonne
car called "Inspiration" that grew out of a 1997 student
project at Southampton University. The car's engine burns
liquid petroleum gas to heat water in 12 suitcase-sized
boilers, creating steam heated to 400 degrees Celsius.
The steam then drives a two-stage turbine that spins at
13,000 revolutions per minute to power its wheels. The
FIA requires two 1.6-km-long runs to be performed in opposite
directions - to cancel out any effect from wind - within
60 minutes. Inspiration made the first run on August 25
and turned around for the return run with just eight minutes
to spare. Before and after each timed run, it took 4 km
to accelerate and another 4 km to slow down. The record-setting
drives came after several earlier attempts had been thwarted
by electrical faults, valve problems, a storm and a tyre
puncture the previous week. But, the team is planning
another run today, to try to get even closer to the car's
theoretical top speed of 274 km/hr (170 mph).
