Going slow saves a lot. When you go faster, the necessary energy (the fuel consumption) grows exponentially? This graph shows the solution to save you some money and the world a climate problem.
An example.
Suppose your taxi driver drives slow, say 40 miles per hour. You ask him to go 60. So 50% extra. He says: “OK, but you have to pay me double money”. Would you do that? You would call him a rip-off, a swindler.
Another example.
Let us say you go 4 knots with your boat. Costs you 4.3 kW, about 2 dollar/Euro every hour. But speeding up with 2 knots to 6 knots, costs 8,5. Would cost you 4 dollar/euro per hour. So for only 50% extra, you have to pay double.
Why are so many people ripping themselves off?
Why are there so many people even trying to make even 7 knots in stead of 6 with their sailing (!) yacht, which nearly doubles the costs again?
In their spare time, even their leisure time.
I honestly don’t understand.
