When the charged electrical particles approach the Earth, they carve out a highly magnetized region —the magnetosphere —which surrounds and protects the Earth.

当这些带电粒子接近地球时，便形成一个很强的磁场区--磁气圈--包围着地球并对地球起一定的保护作用。

But the safety of beaming it back--proposals call for converting the radiated energy into a narrow microwave beam, which would then be collected and converted into electrical energy on earth--makes many people uncomfortable.

Rather than being dissipated into the earth, the electrical charge stays in the key, which throws off sparks when approached, say, by the experimenter's finger.

Earth Hour does lessen the electrical load of power plants to some extent, thus making a small contribution for that hour by lessening the amount of coal burned.
