- Hypersonic Aircraft Powered by Hydrogen
Following NASA, also the European Space Agency ESA plans to develop a hypersonic aircraft. The European INVICTUS project even goes one step further and aims add an environmentally friendly propulsion system using Hydrogen. In addition, the aircraft is supposed to take off horizontally, so it can start and land at conventional airports. As hypersonic airfact travel close to space, this shall one day provide convenient access to space travel. Yet this is still science fiction – NASA estimates the development will take decades and predicts commercial travel in the 2050s. - Czech Railways End Traditional Dining Car Service
Some sad news from the Czech Railways CD. They plan to decomission their old-style dining cars on the trains connecting Prague with Berlin and Hamburg. They will be replaced by modern Bistro cars. Gone are the days where you would get your traditional Czech Roast with dumplings, prepared in an actual kitchen and served on a table with table linen. It was the last dining car where you could get to feel like you were in the “Old Europe”. Now also this train arrives in the present. Too bad I never had the chance to dine in one of those cars. - Snake on a Globe
Ever since I got my first mobile phone – a Nokia – I love playing Snake. I also love maps. This browser game is the perfect combination of both – you play Snakes on globe! You guide the snake from one city to the next. The next city is randomly chosen, and you only see the city’s name. You need a good knowledge of geography to find the shortest way and get the highest score. A perfect way to pass your time and test your geography.
Also have a look at the author’s other projects, he has a knack for visualisation of information. After spending more time than intended playing snake, here is another way to spend countless hours!
