PORTABLE APPARATUS FOR GENERATING ELECTRICAL ENERGY
First Claim
1. A portable apparatus for generating electrical energy, the apparatus comprising:
- a. an electrical energy-generating device for generating electricity in response to input mechanical action;
b. a gravity powered drive for supplying the said mechanical action to the electricity-generating device by the descent of a suspended mass under the force of gravity;
c. a protection system adapted to prevent a drive force experienced by the electrical energy-generating device due to the input mechanical action from exceeding a predetermined threshold as a result of an overload condition.

Abstract
A portable apparatus if provided for generating electrical energy. The apparatus has an electrical energy-generating device for generating electricity in response to input mechanical action, and a gravity powered drive for supplying the said mechanical action to the electricity-generating device by the descent of a suspended mass under the force of gravity. A protection system is provided to prevent a drive force, experienced by the electrical energy-generating device due to the input mechanical action, from exceeding a predetermined threshold as a result of an overload condition. The protection system may perform the dual function of physically protecting the electrical energy-generating device whilst also providing clear feedback to the user that the apparatus is subjected to an undesirable overload condition.
