will that be for here, or to go?

This mobile solar cooker is on display at the MTN Sciencentre in Cape Town. According to the display panel,

The Sustainable Energy Society of South Africa, in collaboration with the Soweto Information Centre in Johannesburg, has initiated a project to promote the use of solar cookers in urban and rural environments of South Africa.

Mathias Weber decided to make a solar cooker more mobile by mounting it onto a tricycle, which is used by the Greenhouse Project for Recycling Programme. His 'Solar Tricycle Pilot Project' has been active in Newtown, Johannesburg, since May 2005 and has created a huge awareness of alternative cooking methods.

The tricycle-mounted solar cooker can cook porridge, pop popcorn and heat up a variety of dishes, using only the energy of the sun.

Currently, street food vendors in South Africa use hazardous, unhealthy and costly methods of cooking, such as paraffin stoves, Primus stoves and Imbaulas (perforated paraffin tins with a fire inside). These cooking methods release harmful gases and ashes into the atmosphere and contribute to the development of respiratory diseases.

Solar cookers are clean, non-polluting, efficient and cost-effective and offer a very viable alternative for street food vendors.

For photos of the cooker out in the community, and a description of Mathias' work, have a look at the Solar Energy Project. The site also describes other solar food projects in a number of countries.
