<p>A method of charging/recharging a secondary cell (24) by rectifying transmitted microwave energy which may be supplied by an unmodified microwave oven (18) into which it is placed. The secondary cell (24) or an article, such as a portable transceiver (10), containing a secondary cell is protected from the harmful effects of microwave energy using a Faraday cage (12) and an antenna (16) disposed outside the Faraday cage picks up the energy which is rectified using for a Schottky barrier diode (26). Optionally the secondary cell may be disposed outside the oven (18) and the rectified current is supplied from the interior of the oven by way of conductors and/or a suitable connector.</p> |
