From Andy Crowhurst
Further to John Heathcote’s letter regarding reducing speeds in order to
reduce fuel consumption
(Letters, 6 June, p 65), I recall a physics lesson
where the teacher was explaining that we consume fuel to accelerate and then
dissipate the energy acquired when braking. He suggested that by putting a brick under the
accelerator, energy would be saved by not being able to accelerate rapidly.
One of my classmates was then quick to point out that the energy was lost in
braking and that a brick under the brake pedal would be a far better solution.
Needless to say, no tests have yet been undertaken.
