French cyclist Francois Gissy has reached a speed of 163mph
(262km/h) on a mountain bike to set a new record of top speed on a mountain
bike.
The previous record of 150mph (251km/h) was broken on a
track near Munchhouse in Eastern France. The previous record was set in 2002.
The mountain bike was powered with an hydrogen rocket which
uses hydrogen peroxide (H2O2).
Surprisingly, the French cyclist is said to have designed
the bike himself using an ecological monopropellant motor produced by Swiss
company Exotic Thermo Engineering (ETE) and Engineer Arnold Neracher.
The concentrated liquid hydrogen peroxide of about 90%
concentrate is fed from a storage tank into secondary chamber filled with a
catalyst (which could be ethanol). This causes the chemical bonds to breakdown
and the hydrogen peroxide to decompose into heat, water (H2O) in the
form of 340C steam, and Oxygen (O). The steam is forced through a rocket nozzle
to provide thrust.
That is a breakneck speed!
