    First!

    Neat.  The side of me that pairs beers with chocolates wants to see this work paired with that of the Open Source Ecology people.

    Brilliant. Refreshing to see an attempt at an impartial text into this subject.

    Why is a train made of heavy steel when it would be more efficient if they were made of a strong and light material like carbon fibre? or even a car made of CF?

    (Carbon fibre weighs roughly 1,800kg per cubic metre, which compares well with mildsteels at around 7,800kg per cubic metre.)

    Cost.

    The following (2yo, but I don’t think things have changed much in the mean time) graph shows comparison of costs for carbon fibre vs steel in car manufacture. Note the cost shown is per vehicle, not per kilo – i.e. it already takes the weight saving into account.
