    Default Ancient Inventions and Electric Cars

    An inventor called Jack Bitterly in a laboratory in Southern California has invented a flywheel made of densely packed carbon fibre that rotates at 100,000 revs per minute and as the wheel turns it generates electricity which could be used to drive an electric car. This story and stories about ancient inventions such as an aeroplane and an analogue computer can be viewed at https://youtu.be/bQJvyRLSl9U - allow an hour and a half to watch it. Very interesting.
    It is better to wear out than to rust out.

    Saw a Sky doco similar once.
    Antikythera mechanism

    And Roman concrete.

    And we moderns think we're so clever, ah but our concrete is rubbish.
    Although the Romans pinched the idea themselves to be fair....
