PURPOSE: To provide a generating device that eliminates the need of fuel, is economical, safe, and convenient, and can be moved anywhere for generation, by dropping and rotating a material to be dropped consisting of soil, stones, and sand from a high location onto an impeller where a generator is mounted via a funnel-shaped chute.

CONSTITUTION: Soil, stones, and sand are used as materials to be dropped, they are dropped from a high location onto an impeller where a generator is mounted via a funnelshaped chute, and the generator is driven by rotating the impeller. In this generating method, the materials to be dropped are accommodated in a container being provided, for example, at an elevator or a belt, are lifted up to the high location for dropping the materials to be dropped, and are naturally dropped from the high location onto the funnelshaped chute for rotating the impeller, thus eliminating the need for any particular fuel on generation and obtaining a generating device that is economical and achieves generation at any location.
