Many families own portable radios but use them very sparingly due to the high cost of dry cell batteries (which can cost the equivalent of three days' food). By converting existing radios to work from the sun, not only are running costs greatly decreased, but it also reduces the pollution caused when batteries are discarded. For a small radio, the cost of conversion can be as little as $1. A small company in the UK has come up with the simple solution of DIY solar conversion kits. These kits contain sheets of solar 'glass', leads, lead connectors, plastic moulding (to fix leads to glass) and glue. The smallest kit can be divided up to convert 30 small radios to solar power and costs just £15 plus postage. Each kit is supplied with detailed instructions and an example showing how things fit together; such assembly-work would make an ideal small-scale local enterprise. The leads are fitted to each end of a piece of 'glass' and connected into the radio's battery compartment, in place of the usual dry cells. For night-time use, either dry cell batteries or rechargeable NiCads can be used. Similar kits are available to recharge NiCads, giving the option of day and night solar powered listening from radios and radio/cassette players and also for powering torches.
