Solar Radiation Management
Cool, Irrigate and Power the World
Harvesting drinking water from the air with the power of space
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
Hot diodes! Banned cheap cooking and electricity for the world’s poor?
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
Silver plants and double-sided modules cool your roof and increase the yield by 16%
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
Marine carbon storage as a path to decarbonization
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
How our clouds stay bright and why we should mirror dark roofs
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
IEA: 630GW of solar to be deployed annually by 2030 to reach net-zero – Mtoe to TWp Calculator
PV Tech | Developers will need to install the equivalent of “the world’s largest solar park roughly every day” by 2030 to support global net-zero emissions targets, according to a new report. The International Energy Agency (IEA) has released its first Net-Zero Strategy today (18 May). Called Net Zero by 2050: A roadmap for the
World largest Off-Shore floating PV of 5 MWp
Sunseap Group, Singapore’s leading solar energy provider, announced today that it has completed the installation of one of the world’s largest floating solar farms on sea water in the Straits of Johor. It is hoped that the successful building of the five MW-peak offshore floating photovoltaic (OFPV) system will lead to more OFPV projects in
Ministry Of Environment In South Korea Planning 4.2 GW Floating Solar Capacity On 6 Dams
After 2.1 GW floating solar project was announced by South Korea in 2019 to be set up by Ocean Sun and EN Technologies, the country wants another 2.1 GW floating PV. The South Korean Ministry of Environment is planning to further expand the country’s floating solar PV capacity by as much as 2.1 GW, growing
How to cool and power the world
We can now calculate a lot. There are countless climate models, including theoretical assumptions, if we built 20% -50% of the Sahara with photovoltaics, the temperature in the Sahara would increase significantly due to the much darker surface of the photovoltaic modules. Less radiation will be reflected back into space by the bright desert sand,
Bifacial modules on flat roofs provide a quick and easy ROI – enough to cool our cities
Can we have both? An ideal Performance Ratio Photovoltaic Project and enough Return of Investment to rebuild our cities to become more resilient against urban heat islands? We learned these days, that with no mitigation, cities will turn into ovens. We will see an increase of 4.4 ° Celcius! This is huge and will be
