an airline could save approximately a total of seven minutes per aircraft per gate push-back...

Essentially the savings could provide an airline with a lot of extra time every day and that time is worth a staggering amount of money. For American Airlines and Southwest Airlines, the number is around a billion dollars per year. Even British Airways, with the smallest potential savings of $166m, should find this item riveting. Every airline, especially network airlines, are desperate to find operational savings. Here we see an example staring them in the face.
One can argue the number of minutes and the dollars per minute. Change them, and even then, the potential dollars saved is a large number.

Airlines that deploy e-taxi could see big time savings that could mean getting another flight out each aircraft every other day or simply serious financial benefits – taking 30 minutes as a guide, this is worth $3,000 per day per plane. Improved operational efficiencies are significant.
MIT engineers are proposing a new way to reduce a plane's lightning risk, with an onboard system that would protect a plane by electrically charging it. The proposal may seem counterintuitive, but the team found that if a plane were charged to just the right level, its likelihood of being struck by lighting would be significantly reduced.

Pellet c'est juste la forme du conditionnement
What’s interesting is, if you look at the rear T-38, you see these shocks kind of interact in a curve,” he said. “This is because the trailing T-38 is flying in the wake of the leading aircraft, so the shocks are going to be shaped differently. This data is really going to help us advance our understanding of how these shocks interact.”
