Obtaining fresh drinking water from the air has been very energy intensive for a long time. Researchers at ETH Zurich have now invented a currentless technology that uses the cooling of space for this. The new device essentially consists of a specially coated pane of glass that both reflects solar radiation and radiates its own heat
The establishment sees itself endangered by the social energy turnaround, as I myself got to understand from my sisters (!) Through enormous hostility and the associated financial loss. One more reason to stand up for it: Direct DC solar power (DDS) can inexpensively cook food and charge devices. The insulation of the cooking space enables
The design options with modules on both sides and green roofs are large and very interesting. Cities are increasingly having a problem; they get hot too quickly. Green roofs are ideal, as they can actively cool the roof through the evaporation cold. But the question is often whether a white roof is not more efficient due to
The first research mission of the German Marine Research Alliance examines the oceans as carbon stores A look over the garden fence often helps. While the climate discussion in Austria does not really go on, there is already massive research into CO2 storage(CDR) in Switzerland and Germany. In Austria most people still assume that we will
