At first glance, the idea sounds fantastic: if the entire Sahara were equipped with solar panels, the world’s energy needs could be covered four times. Researchers calculated that some time ago. The idea is also gaining traction because the area is largely inhospitable and uninhabited. So there would be no competition for space. The first … Read more
The Sahara is literally overflowing with energy: within a few hours, photovoltaic cells can harvest more electricity there than humanity uses in a year. Unfortunately, so far this energy is only available regionally, as an early 2000s project to import the electricity to Europe failed. Now British entrepreneur Simon Morrish wants to pick up the … Read more
At first glance, the matter seems clear. Researchers in Japan analyzed detailed data sets on global forest cover from 1960 to 2019. Two opposing trends were observed: while deforestation has stopped in most richer countries and the number of trees has even increased again, in poorer countries the tropics still lost huge areas every year. … Read more
In 1967, US intelligence analysts discovered on satellite images a previously unknown structure about 100 meters long. It was therefore initially referred to as the “Caspian Sea Monster”. Later it turned out that it was by no means a mythical creature. Rather, it was the work of Soviet designer Rostislav Evgenievich Alexeyev that the Americans … Read more
