What is our next fuel source?

Realistically speaking, what's the world's plan after oil reserves are exhausted? When exactly are we going to stop drawing energy from dead plants and carbon rocks?

Synthesis? Nuclear energy? Solar? Hydrogen?

I'm interested in engineering science, so no need to spare details. I've read articles and watched tv shows on the subject.

    The solution to the energy crisis is within our grasp and it is more amazing and wonderful than we could have ever imagined. 'Concentrated Solar Energy' uses simple mirrors to focus sunlight onto a single surface to superheat an oil like fluid which is pumped into a water chamber which powers a steam turbine. Because 'heat' is created, transferred, and consumed by the processes which change the molecular kinetic energy of matter, the heat that is captured and converted to mechanical energy through the CSE processes will result in a net reduction in our global temperature. CSE arrays installed over 1% of earth's deserts would yield enough energy to power the entire world at about 1/5 the cost of fossil fuel. A few large floating CSE arrays stationed over equatorial waters and a handful of obsolete oil tankers retrofitted with power towers and converted to mobile power plants could be systematically rotated and used to create and transport heat created energy to every coastal city in the world. The byproduct of installing CSE arrays over key areas of our oceans would be clean cool air, desalinized water, and possibly the improvement of oceanic ecosystems as well as the stabilization of tropical weather patterns.

    The ecologic benefits of electric or hybrid cars can be much better appreciated once we no longer burn coal to create electricity. However, the most efficient engine design is not the one powered by steam, electricity, or combustion, but by compressed air. Internal combustion engines convert heat energy into mechanical energy by igniting gasoline, but it is the pressure of rapidly expanding air that moves the cylinders. Theoretically, an identical process can be created with compressed air in our existing engines. Best of all, the Law of Conservation of Energy which states that energy cannot be created or destroyed promises that the energy needed to compress the air is equal to the energy released by the colliding molecules of the pressurized air as they convert their molecular kinetic energy into heat through friction. This means, theoretically, that the process of compressing air is an energy free process. Byproduct: 1.) A facility that uses heat recovery steam generator (HRSG) technology to compress air can be virtually sustained by the heat energy released in the compression process which it then uses to compress more air. 2.) Vehicles using compressed air release pure breathable air that, when returned to normal atmospheric pressure, absorb a quantity of heat energy from the environment equal to what was borrowed from it at compression, resulting in a net reduction in our global temperature.

    We live in an age of rapid technological advancement and have witnessed the decimation of some of the oldest and once virulent industries which could not adapt in time to survive the onslaught of competition posed by innovative leaders wielding the sword of emerging technologies. Yet, possibly the most antiquated and exploitative of all industries flourishes and remains virtually unchallenged in the one arena that should be the epicenter of technological revolution. The fossil fuel industry survives and thrives because the powers that be fail to recognize the fact that our understanding of the fundamental forces of physics is fairly comprehensive and that we are unlikely to receive any new gifts from this field on par with the discovery of electromagnetism and nuclear fission/fusion in the near future. Consequently, we must accept the fact that any solution to our energy crisis is destined to be the derivative of the technologies that already exist and is, therefore, already in our grasp. The most critical resources we are lacking is the vision to forsee a future where our greatest single source of energy is fully utilized, the imagination needed to implement the technological alternatives at our disposal in the most economical manner, and the courage to commit the necessary resources to the development of the most obvious and inevitable solution.

    We will doubtless have to depend on a kind of sources. Nuclear fission will be giant for some time, but uranium is a restrained useful resource as well. Fusion from hydrogen could hold us going enormous quantities or even millions of years, but up to now we have not been equipped to make it work and there's no promise that we are able to. Sunlight is likely one of the most promising technologies that we've got presently working. We cannot yet acheive the efficiency to hold our civilization or tradition, however we're working on it. Hydrogen gasoline cells are usually not an vigor supply. They're a way (in combo w. Stored hydrogen) of storing vigour. They are limited on the second by our issues in safely storing hydrogen fuel. Biofuels will probably play a giant role at some point. How large a position relies on how good we are able to get fuel cells and batteries to work (somethings acquired to move our trucks and cars). It also depends upon how seriously we take world warming. P.S. It must be noted that fossil fuels will doubtless certainly not disappear. As they are used up, the prices will upward thrust and we will be forced to look to other approach for financial factors long before we run out.

    Dead bodies.....that will also aid in population control. Seriously, clean fusion is the best hope because it is radiation free. And the oceans of the world are the gas tank. It is a tough challenge but I think it will become a reality in the next one hundred years.

    The existing methodologies should suffice if populations start exercising self control. A larger problem at that time may be sources of lubricants.

    nuclear energy is very dangerous and it should be stopped at any stage. we can use solar and hydrogen energies effectively to meet our future demands on fuel.

  • 7 years ago

    first, there will be world wide resource wars that will drastically reduce the population.

    any high-tech sources developed before then will be unsustainable because of the loss of technical knowledge,

    so we will be once again using recently harvested wood and other biomass.
