Acknowledgments

I would like to thank Aidan Murphy from Met Eireann for information regarding remote weather stations. Many thanks are also due to Andy Wilson from The Sustainability Institute, Cooloughra, Westport, Co. Mayo for sharing information on his off-grid system. I must express my gratitude to Hugh Foy of MF Services, Wilton, Co. Cork who answered all my questions on the Cale range of parking meters.
