Gas or diesel? This question worries us when choosing a car. Both the other engine has its advantages and disadvantages. But perhaps the most large drawback, this is a low efficiency. The maximum that can be squeezed out of the heat engine is about 40%. To imagine this, we will try to transfer it into rubles, that is, if you refuel 1000 rubles, 600 rubles will fly out into the exhaust pipe, simply heating the air. And in the near future nothing will probably change. Now more and more often the emphasis is on electric cars. In the foreseeable future, this is perhaps the most optimal option. After all, in fact, the production of epctrists is not so expensive, and maybe even cheaper than traditional cars. The problem in the production of batteries. There should be a very large and powerful battery. If the battery for a cell phone is generally not very cheap, then imagine what is its cost for a car, weighing about a ton, besides, it should also go a few hundred kilometers. Scientists of the whole world conduct research in this area and may soon find a way out.
