Compressed air motorcycle breaks 80 MPH barrier

[Bob]

A motorcycle running on compressed air has recorded speeds in excess of 80mph.

The O2 Pursuit was designed by Dean Benstead, a graduate of RMIT University, in Melbourne, Australia. Based around a Yamaha WR250R frame, it is fitted with a compressed-air engine, powered by a standard scuba-diving tank. It can travel over 60 miles to a single tank.

The O2 Pursuit has been shortlisted for a James Dyson award.

Cool concept.

Best not to ask too many 'hard' questions tho

Enough hot air on this site to keep the bike going forever at 150mph...


A novel concept, possibly never become a realistic 'power' option though.

Anybody divers here want to hazrad a quess at how many solar panels would be required to drive a compressor capable of filling a scuba tank to 3300PSI at the correct rate of fill?

1... very large one

Those are some good performance numbers for air, wonder what sort of motor he is using?

I was going to take a shot at Bogan and tell him not to be so lazy and do some research but then i though pot - black

Between 4 - 8 kw motor required to fill dive tanks depending on rate of fill
4kw for 100l/min (25min fill tme)
Certainly be a big fuck off solar panel.

It would be interesting to see the torque curve.

Thats some cool engine-air-ing!
