InerziaLightning does one thing: it calculates the distance of a thunderstorm from you, by measuring the time between the lightning bolt and its thunder. Obviously, we have to tell the widget when we see the light and when we hear the thunder: this is done by clicking on the same button.
The usefulness is clear if we think to the possible danger to our modem or router due to the overload caused by a lightning fallen too much near us; this widget helps to understand when the thunderstorm is approaching and it’s time to pull the plug from the modem. The speed of sound depends on the air temperature: for this reason, we can insert it in the preferences; on the same back, we can also choose the temperature scale and the distance measurement unit.
If we change the units, the data that are already present will be coverted; we can select meters, kilometers, yards, miles, nautical miles and foot while the temperature can be expressed in Celsius, Farenheit degrees or Kelvin.
Operating System Support: Mac OS X 10.4 or later.
