Abstract: The invention provides a computer-implemented method for determining predicted power generation of a renewable energy installation. The method includes receiving current power generation data indicative of a current power generation value for each of one or more neighbouring renewable energy installations, and determining, based on the received current power generation data, a current data map indicative of current power generation values across an area including the renewable energy installation and the one or more neighbouring renewable energy installations. The method includes retrieving a previous data map indicative of power generation values across the area at a previous time, and determining, based on the previous and current data maps, a future data map indicative of power generation values across the area at a future time, determining a predicted power generation value of the renewable energy installation at the future time based on the determined future data map.

Abstract: A system for alerting motorists travelling on a roadway in a vicinity of a vehicle is disclosed. The system includes one or more projector units, and a respective attachment structure for each of the one or more projector units for attaching the projector units to a portion of the vehicle. The one or more projector units are configured and arranged to project a light signal on to at least a portion of the roadway adjacent the vehicle and in a travel path of the motorist. The one or more projector units include at least one light flare projector unit and/or at least one signage projector unit. A school bus incorporating the system is also disclosed. A method for alerting motorists travelling on a roadway in the vicinity of a vehicle is also disclosed.
