With fossil fuel supplies dwindling and ever-increasing pressure to be environmentally friendly, we should all be looking to head in the direction of green fuels.

Obviously, the best energy source is hydrogen, burnt directly as fuel or in fuel cells. But the real questions are how do we get there — and how quickly?

At present, vehicles in the UK and the rest of the world run on diesel and petrol from crude oil, which is where the infrastructure lies. Creating new fuels (such as E85), which albeit are ‘green’ but cannot be used by the majority of existing vehicles, requires a change to those that can run on new fuels and then a second change to vehicles that use hydrogen.

Surely we should be trying to get to the most environmentally-friendly fuel (hydrogen) in the quickest possible time.

This can be achieved by creating fuels such as Biodiesel that can be used by existing vehicles, and focusing on making the next generation of vehicles hydrogen powered. This would eliminate the intermediate step of changing vehicles to run on the likes of E85.

And the fuel a vehicle uses is not the only environmental issue — once the vehicle has reached the end of its life it has to be disposed of/recycled)

The only thing standing in the way of hydrogen power is the lack of available infrastructure, which can easily be resolved well within the lifetime of most of the existing vehicles on the road.

How to enter
Write a letter to The Engineer and you could win a pair of tickets to one of bmi’s European destinations, courtesy of our friends at the airline.

Flexible and competitive
bmi asked 10,000 customers ‘what would make a great airline?’ The answer was clear: competitive fares, more choice and less time wasted at airports. So bmi acted, introducing a unique fare structure on domestic and European short-haul flights to and from London Heathrow. Thanks to three fare options — including premium economy, with benefits including lounge access and flexibility — you choose the services you want, depending on your business trip.

What’s more, bmi has streamlined the passenger process from the moment of buying the ticket, to your passage through the airport, to boarding the aircraft. You can book e-tickets online and then check in online at home, in your office, or even on the move.

Alternatively, there are self check-in machines and priority check-in desks at the airport. You can even use bmi ‘web points’ to check in online at the airport, if that’s more convenient. All this means you can save valuable time from booking, right until your plane takes off.

The prize
Try the smart approach for yourself, courtesy of bmi. The winner of The Engineer’s Letter of the Month prize for April, as selected by the editor, will win a pair of tickets from London Heathrow to any destination on bmi’s European mainline network.
