There are several unlimited resources, such as Water, Air, Sunlight and Sea, and experts in our country have thought about it in order to anticipate a shortage of resources from electricity and fuel oil, but the government has not allocated all of them, because they cannot guarantee about productivity from unlimited resources, which will cause deep anxiety for all of us, one day electricity and fuel oil will disappear. We can already anticipate this when we now start little by little starting from non-existent natural resources. Finally, we can practice from now on vehicles that use hydrogen so that later we won't be too indifferent when electric power and fuel oil disappear.
You have explained an innovation that is not dependent on electricity and fuel oil, and in general things like that need to be tried by people who have more abilities in order to find out the level of benefits and whether a product like that is good or not. But as we can see now, electricity and fuel oil can still be relied upon as a whole in all sectors in the world. So it is still very difficult to rule out electricity and fuel oil even though new innovations always need to be tried to get an assessment of the benefits from many people.
