Kraftvärmeverk producerar el, och levererar värme till fjärrvärmenätet. Nätets returflöde till dessa verk har generellt en relativt hög temperatur, och det finns idag verksamheter som använder sig av denna returvärme för att värma upp anläggningar och utrymmen som har värmebehov. Det finns en potential att på liknande sätt utnyttja denna för uppvärmning av växthus, vilket utgör en synergimöjlighetCogeneration plants generate electricity and supply heat to the district heating network. The return flow from the network to these plants generally has a relatively high temperature, and there are currently operations that utilize this return heat to warm facilities and spaces with heating needs. There is potential to similarly use this return heat for greenhouse heating, which presents a synergy

Video cameras are widely used for gait-based surveillance systems. However, they raise privacy concerns in sensitive environments such as private homes or restricted areas.
