<x-rich><color><param>0100,0100,0100</param>The Royal Academy of Engineering requested my input on "The
future of Aviation". I provided the response that follows. I realize
that most of it wasn't really in the area or from the point of view
they were seeking input but I don't think that matters.

<bold><italic>Dear Mr Ploszek:

I'm replying in my role as regional director of the Tyndall
Centre for Climate Change Research. My concern is here
exclusively concerned with reducing the CO2 emission from
aircraft. While at present the proportion of CO2 associated
directly with aircraft movement is small, because air traffic is
growing and there is at least a vision for reducing CO2 from
automobiles, it is likely that releases from aircraft will become
a substantial contributor in the next decade if nothing is done.

* A major "driver" of the present pattern of evolution is that
there is no tax levied on aviation fuel. This is a problem that
MUST be tackled, desirably at a world level but at least within
a European framework.

* Moreover, if the Government introduces a carbon tax, that
should also be applied to aircraft movements. [Again
international agreements are required]

* The above development would provide a stimulus to the
development of fail-safe designs for hydrogen-fuelled aircraft.

* It seems to me that more should be done to develop modes
of aerial transport that consumed much less fuel per passenger
mile than existing schemes (whether or not one is adopting
hydrogen as a fuel). Perhaps there is scope for the return of the
airship ...or perhaps some hybrid, intermediate version
between an airship and a conventional aeroplane. Of course,
this would also greatly reduce the problem from the other
main pollutant source with aircraft: noise! No long runways
would be needed either.

* In connection with the above, with leisure transport,
especially high speed is not of great advantage since at
present, for European flights, actual flying time is less than
(often MUCH less than) one-fifth of the total journey time from
home to hotel. So a comfortable airship flight at just 400km/hr
might be very attractive, especially if the fuel savings were
properly factored into the ticket price.

* Although the photographs released of the NASA solar-
powered aircraft are both intriguing and impressive, it seems
likely that the commercial implementaion of such a scheme is
a long way off. Nevertheless, it's surely a goal to be pursued.

* Finally, more need to be done to ELIMINATE short internal
flights in this country by providing <underline>highspeed</underline></italic></bold> <bold><italic>rail links,
including direct links between airport terminals.
