The environmental and climate balance of electric cars improves significantly when they are charged with green energy. It is not far from this realization to the idea of solar cars. Ideally, these no longer need to be charged externally at all, because they store the extracted solar energy directly in their battery. In practice, however, … Read more
The American space agency NASA wants to test a new technology that allows smaller payloads to go into space with much less energy consumption. The method was developed by the Californian company SpinLaunch. It is a catapult, a small rocket that holds the cargo in the hold. Accelerated to hypersonic speeds and accelerated into space. … Read more
SpaceX is probably by far the best-known private space company. But it is certainly not the only one. For example, there is the startup Rocket Lab, which operates its own launch pad in New Zealand.

On the other hand, mines and quarries are … Read more
Amazon obviously takes its climate goals seriously. In 2019, the group announced its intention to be CO2 neutral by 2040. To this end, the truck fleet is now being tackled: little by little the diesel trucks are being replaced by e-trucks. The first five vehicles will start in the UK. The new fleet saves 170 … Read more
Deutsche Bahn is currently testing a battery train in Baden-Württemberg. In the medium term, such towing vehicles can be an alternative to diesel trains on routes without overhead wires. Climate neutral: a challenge for rail Deutsche Bahn aims to be climate neutral by 2040. Already today, approximately 90 percent of transport services, both in passenger … Read more
Traveling by train is generally considered to be particularly environmentally friendly. That’s not wrong either. Deutsche Bahn could strike an even better balance, especially when it comes to climate protection. Because while the trains in the Netherlands are exclusively supplied with wind energy, in Germany coal-fired electricity is still used. In addition, the route network … Read more
The classic glass of wine with dinner, the traditional beer after work: both were previously considered harmless, but the effects on the brain are stronger than expected.
