The present invention eliminates growing weeds without fatigue, without the use of chemicals and in an environmentally friendly manner. You pilot the drone on the part to be treated and it suffices to apply the intense heat of the weedkiller to the grass so that the plant cells burst and the weed dies. The device, which is recharged autonomously by solar panels, has completely carbon-free energy which prevents the amplification of climate change. The device does not emit any polluting molecules, therefore totally clean for the planet. Figure for the abstract: Fig. 1
