The gears in the insect legs are not connected to power ratios, and only synchronise the action of the jumping legs.

With a weight-to-power ratio of 10.9 kg per kW compared to the RX-2's 9.9 kg per kW, the RX-3 was slower.
13.
The pressure ratio ( as opposed to power ratio ) is not inverse-square, but is inverse-proportional ( inverse distance law ):
14.
The thrust-to-power ratio is enhanced because the water approaches the propeller in a linear configuration and exits the nozzle the same way.
15.
Nano electrokinetic thrusters have a very high efficiency, specific impulse, exhaust velocity and thrust-to-power ratio which make them suitable for a wide variety of applications.
16.
In weak ice and mild ice conditions, the power ratio between the bow and stern propellers could be reversed as the latter have higher propulsion efficiency.
17.
It is also theoretically possible to achieve a very high efficiency of nearly 100 % as well as a high specific impulse and high thrust-to-power ratio.
18.
The study said that the system was " consistently performing with a thrust-to-power ratio of 1.2?.1mN / kW ", and enumerated many potential sources of error.
19.
If the original friction-to-power ratio was, say, 1 %, that implies the smaller drill will have 10 times as much friction as power; the drill is useless.
20.
Moore's Law isn't some rule of nature but the result of engineers'hard work and occasional breakthroughs, which keep the price / power ratio declining instead of leveling off.
