The important thing in today world is clean energy obtaining from non-chemical ways. The problem is generating great quantity of electric energy which can be converted to other kinds of energy like heat or light with process different from burning in oxygen or other chemical exothermic reaction processes. There is a need to invent a form of energy not based on nuclear fission or fusion, what not always can be connected with high energetical processes like in nuclear technology.
Energy can be produced continuously in small portions suitable for one home energy requirements but in infinite term of time. The existence of country electric grid is doubtful in this approach, and the spread systems seems to be the right solution for many reasons. We can produce electric energy from sun, wind, or tide but those are environmental energies we cannot trust for hundred percent sureness especially when we need to generate it on other planets where there is no suitable atmosphere or in outer space far away from the light of stars. We need fuel-less and more versatile energy sources, safer in usage. Although the beginning of the civilization was formed on burning wood and coal, where those materials were needed to powering the steam machines during technical revolution in eighteen and nineteen century, the main human requirements according to the energy generating weren’t fulfilled in those times and they aren’t fulfilled now. The main limit of steam engines was exhaust gases and smokes as well as low efficiency of transforming obtained energy. The important and crucial civilization leap was made when humanity started to use electricity based solutions, invention of electricity was a milestone in human history, even if electric motors were neglected in preliminary stage in those days, the electricity was required for internal combustion engines, where it was needed for initiate the ignition processes. People started to gain the opportunity to learn after sunset when first lightbulb was invented without need to apply oil lamps which light was too weak for reading, and children were losing sight in this faint light. Now as a inhabitants of this planet we are strongly accustomed to all these improvements like clean water in our taps, light from led lamps, warm from central heating based on heat pump or gas stoves , etc. However, the supply system that is responsible for all these comfortable for us things is not safe. Humanity has nuclear plants, that needs cooling from sees, lakes or rivers, we are dependent from electric grids and if the grids would be destructed we couldn’t find any solution for this disaster. Despite of this, humanity has invented mobile energy generators based on internal combustion engines that needs a lot of fuel for work. The fact, that civilization is so dependent on fuels is catastrophic, if one would think about all danger implicating from this situation. But all predictions would be not plausible if someone would be trying to think that the fuel resources on the planet will be endless, that we’ll be able to produce it from carbon dioxide and water from the atmosphere of our planet, preliminarily emitted to it by ourselves, or something like this. Carbon dioxide is a waste exhaust gas with which none of wise people have no idea what to do, in vain is pumping it into underground carbon dioxide reservoirs. Humanity should face the fact that we are living on the edge. Someone really wasn't done his best about it. Humanity is not free, we are not living in freedom, for many reasons and the one them is the fact, that it is energetically dependent. Freedom is for that people who are now on the top of the world. For instance for the energy producents which are ultimate dictators in the process of life on this world. To be honest, this civilization hasn’t even a faint idea about its own cosmic neighborhood, faint recognition what is happening in nearness of own planet due to lack of seriously advanced space propulsion, this system is conservated by still the same institutions and economic processes. If this situation is to turn for better, the approach of technology dictators must be changed by people which are acting outside this deal, but it is rather obvious that the dictators won’t change their technology course due to their own economic environment that is for them a source of serious income. Besides the situation of global invalid processes that lead us to the edge of serious trouble is no only based on their activity, because this process was implemented through many years and at the beginning it has its own disadvantages which today start to bring many problems. Some strategies were wrong from the beginning, and although some inventors was trying to implement certain improvements, they were muted by system’s people and their harmful activity what is visible today on the global scale. Those who are so proud for the rocket propulsion, advanced electronics and latest progress in artificial intelligence systems, will not be so proud when the fuel for rockets or current for computers will be lacking for certain simple and easy to recognize reasons. Without any progress in technology of producing electricity or in propulsion for vehicles we won’t be able to go farther than the orbit and nearness of our own planet and even the colonization of nearest planets in solar system would be very difficult. For sure with only jet and rockets propulsion we can’t escape using crew expeditions outside solar system, and we won’t be able to colonize Mars in this century, and I don’t talk here about sporadic crew landing on Mars surface, what can take place in this century but we will not be able to fund there any larger system of facilities or habitats for sustain people living in good conditions. Building a city on Mars in this century is a fairytale with application of rocket propulsion. Other words, we cannot operate freely in space using only rocket systems. It is dramatic situation, that for exploration of space there is lost so much financial resources, only for sustain current not healthy situation in transport in outer space. Before we started space exploration by use of rockets, one should count advantages and disadvantages, maybe better situation would occur when we would be improve the system of propulsion we will be apply, before we start sending loads ad crews in space in rockets deck. First we should work out the technology of propulsion that would be adequate for cosmos dimensions before we start to do anything.
Humanity can’t improve rocket propulsion to nuclear rocket propulsion because of dangerous fission wastes produced in the process of nuclear propulsion, such systems are instable because they need high-enriched uranium or plutonium for operation. Much safer is looking for less risky methods of propulsion like reaction-less propulsion types. Although such propulsions are for now in preliminary stage of theoretical works or there are existing already certain types of prototypes which are working with low efficiency with some exceptions based on work of certain inventors which were more successful on that field but they were not noticed by proper institutions or influential people with premeditation or not as a promising people with vision, still some inventors don’t want to publish their revolutionary works to wider society for many reasons.
