Why human can't find fuel instead of pretroleum?
The human use pretroleum as the energy of car,plane,ship, generate power and industries for more than 150 years. According the statistic, the oil of the Earth would run out in next 40-50 years. So find a energy that can replace that oil is a serious problem.
We can see some advanced in project of "replace oil ", such as nuclear-powered ship and eletric train, like Toyota and General Motors throw some new concept stype car: electric cars and hydrogen cars, but their sales price too high and lack of supporting facilities. so the consumers hard to accecpt it, the new energy car can't achieve universal. And we lack of new energy technology apply on air-crafts. For instance: the hydrogen plane was invented?
The NASA already send "curiosity" land on Mars, May be the human being be able to land on Mars in next 50 years by the fastest.I hope the human can landed on Mars as I alive. Please don't tell me ,the USA or other Earth countires use spaceships who burnt the oils starting their journey?
Another independant topic, if the human develope the space ships that capable to sail the solar system. Do you agree install the nuclear warheads on these spaceships? Because launch the nuclear warheads from space to the Earth, its only serval minutes,it is hard to intercept and forecasts.
Let us assume that some terrorists hajck the sapce civilian vessel " Gold Princess" who travel to Mars in 2095, there are 9000 tourists on the ships. the terroists install some nuclear cruise missiles on the ships. And disguise the civilian vessels fly to the Earth. What respond of the Eath? Maybe the Earth defense command call on radio like in hollywood science fiction movies: "Unidentified flying objects, show your ID numbers ,or we will fire."
The two topics, you can discuss the one you interesting, or both.
