From Michael Harper
While reading the article on Iceland and hydrogen fuel cell cars
(This Week, 1 May, p 20),
I started to wonder about the environmental effects of replacing
petrol engines with fuel cell versions.
The petrol engine was originally hailed as a clean alternative to the horse,
which left the streets ankle deep in muck and attracted disease-spreading
flies.
When our cities are filled with vehicles producing water vapour, will we look
back on the golden age of petrol engines, when the streets weren’t more humid
than a Turkish bath and there wasn’t a rainstorm every night?
