another green concern is the composites we use, not just the disposal of, but the carbon footprint of producing the raw material

we've been using basalt fibre with bio resin for prototype race car bodywork but basalt is produced from volcanic rock so the carbon used to melt that must be high

we've also looked at natural fibres like hemp based fibre with bio resins but not tried them in anger yet

lets face it we can make many efforts for craft to become carbon neutral but the travelling and transportation of us and the craft will outweigh any efforts we make to make the sport 'green' just like the F1 KERS systems' a token drop in the ocean compared to the freight, shipping costs, totally floodlit race tracks etc etc
