Apologies to the organisers of the 1-day technical meeting “Waste Energy Utilisation” publicised in MNM last Monday.   The meeting takes place on 24 March and not on 24 April as incorrectly indicated.  All details appear on the IFRF Events Calendar and participation is enthusiastically encouraged. The meeting is offered by the British Flame Research Committee in collaboration with the Institute of Physics Combustion Physics Group and takes place in Rotherham.  It will be of interest to energy managers, energy policymakers, equipment manufacturers, research practitioners and students; performance & economic system modellers.
