positive because it helps us breath, and can power millions of homes!
AnswerNegative. Because wind turbines are so inefficient, they can only be build through subsidies, raised by increasing everyone's energy bills. They are bankrupting the economy.

The quickest and best way is to look at the battery. If your positive cable (+) is going to the frame or body, positive ground. If the negative (-) goes to the frame or body, negative ground. I believe that a MF 35 is a neg ground system but use the check from above.
It is not the energy that will be dissipated out into the environment is doing the worst damage, it is taking out of the geothermal energy from the Earth that do. Geothermal energy keeps the Earth alive.
Electrons move from areas of negative charge to areas of positive charge and produce an intense spark. Some lighting reaches Earth because negative charges at the bottom of storm clouds may cause the surface of Earth to become positively charged by induction.
Negative earth
in 1978 with the T140E
poitive
No. A lot of cars in the 1960's had positive earth.
That depends on what reference level you have chosen. If the (arbitrary) reference level you chose is Earth's surface, then anything on the Earth's surface has zero potential energy. If you choose some higher reference level, an object on Earth's surface has a negative potential energy. If you choose a lower reference level, an object on Earth's surface would have a positive potential energy.
AnswerThere is no positive and negative. There is hot and ground. The hot (120 volts AC) is in reference the ground (Earth).
The Earth's core
The Crab Nebula is too far away for its energy to have any impact on Earth.
The Sun
"geothermal" (the source is a combination of original impact energy and radioactive decay.)

Positive * It lights up the earth at night * It gives us a talking opint * It is an objective to reach * It gives us tides, and tidal power Negative * It encourages werewolves!
