After the film ‘Don’t Look up’, everyone is talking about climate change again and climate researchers like Peter Kalmus are calling on the community to rethink things and allow experiments. I want to follow the thought of a possible hostage situation of the weather a little: In 2009 I organized a photovoltaics conference in Bulgaria in order to be able to push
Enhanced radiative cooling of solar cells by integration with heat pipe via PV Magazin | Thermal management of solar cells is of vital importance to maintain adequate electrical efficiency. Lately, radiative cooling (RC) of solar cells has been researched extensively because of its passive nature and structural simplicity. However, commercial solar cells are usually encapsulated
The dual use of agricultural land as a power station and food cultivation is a really promising approach. We can continue to provide cheap food and at the same time get cheap solar power. In Germany there is a lot of discussion about it and hopefully there will finally be more movement in the market. We definitely need
The US startup Erthos is convinced that by dispensing with conventional assembly systems and laying flat modules only with wires to hold them in place, it can reduce electricity production costs by more than 20%. The considerations apply not only to open-air systems, but also to flat roofs and, to a certain extent, to bodies
I got the opportunity to visit the Tartufo Totale in Vienna on Saturday. The event took place in the Vienna Ballhaus and was hosted by the restaurateur Hannah Neunteufel, who did not take the opportunity to do an interview with the truffle blogger Luca Miliffi. Miliffi and Neunteufel then discussed why climate change and the
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
Architecture and taste are also subject to a trend. In a society that is currently overwhelmed by stimuli, people long for clear lines and tidy architecture. Maybe an explanation why there are more and more dark roofs, dark walls and dark aluminum fences and less green. Our history and our associated growth also seem to produce more
