A carburettor is connected into the inlet duct of an internal combustion engine. Devices of the invention are particularly suitable for use on one side of a membrane, such as fabric membrane, to provide electrical power or visible light on the same, or on an opposing side, of that same membrane, or at a distance from where the radiant energy is gathered. The compressor is configured to compress fluid. Operating an electronic component beyond its rated operating temperature range will damage electronic components.
