The electric cars are not without pollution and other problems

Electricity must produce somewhere  https://crisisofdemocracticstates.blogspot.com/ Kimmo Huosionmaa Many times before I have written about technology, what is used in electric cars, and why those cars are ultimate challengers for normal cars. But as you know there is no product, what is without environmental problems. Here come the critics against electric cars, what somebody has been waiting. There are a couple of environmental problems with electric cars, and one of those problems is, what happens to used batteries, and in those vehicles is used many synthetic materials. So what would those wrecks happen, when they are removed from traffic? They are similar wrecks as other cars, and that makes them problematic for the environment, and those composite materials are hard to recycle. So here I must say that the electric motor would just transfer the pollution to another place, and if the electricity would not produce by using clean methods would the environment load o...

Another strange polar explorer: Salomon Andrée 1897

Famous picture of Andrée's balloon wreck https://gamesandtehories.blogspot.com/ Kimmo Huosionmaa Another very well known polar expedition was made by Salomon Andrée or S.A Andrée (1854-1897)  in 1897, and that trip was fatal for him and his two mates. The expedition seems very interesting because when Andrée left for his final journey, he used the hydrogen balloon, what was made of rubber. That means the balloon couldn't be fixed if something made the hole on it. And because the balloon was made of rubber, the refilling with hot air was impossible. There is the fatal design error in that balloon. If the air sailor wanted to use hydrogen balloon, should the rubber balloon put in the canvas balloon, what would make the trip safer. The problem with hydrogen balloon is, that it can raise very high, and be trimming the altitude must the hydrogen released from rubber balloon. And in the case of Andrée, this gas must be replaced by something. If the hydrogen balloon wou...
