It seems John Deere are looking into it.

The thing the greenies are blind to is yes the vehicle is 'green' but it's running on power from a power station somwhere and will never be fully green if you take into account the manufacturing etc.

Of course this is all old technology as the electric car was in use since the early 1800's with a petrol-electric hybrid in 1911.

As Hazelwood being closed has already shown through the SA power failure causing the Portland smelter to come to a halt. I did a CAD course early this year with some of the workers and they're already looking for other jobs as the power failure has guaranteed the closure of the smelter in the next few years. So much for keeping jobs! When the smelter goes it will take all the other support businesses with it - it'll become a ghost town sadly.
