    I'm getting older and still waiting for science
    to introduce new thought to replace our old
    and worn ideas. We don't seem to be able to
    find solutions for energy and propulsion.

    And if the new thoughts are anything like the ideas in your gravity thread we would revert to living in caves wondering if rocks were edible. It's a good job the scientific method works and your ramblings will in no way replace anything.

    Perhaps they should award large prize money to those who can demonstrate new technology like they gave with sending people into space for cheap.

    Isn't it a good thing that as far as we know are theories are correct? This means we're one step closer to the mind of god.

    I for one am certainly glad that as far as we know everything is right!

    It means the theories are the best available model of what actually happens but they can always be refined or thrown out if a new observation contradicts them.

    This is science, philosphy is down the hall.

    There is no guarentee theories or models are "right" they currently are the best available but there is no guarentee that they will not be superseded by a better model as more observations are made.

    Clearly you are not paying attention. New ideas are being thought up with such frequency that it is impossible for an individual to keep pace with them, even within a small segment of science. Perhaps you should start examining the real world, rather than your faulty perception.

    Since we currently acquire energy through atomic fission, coal, gas, petroleum, hydro, wind and wave power, geothermal and tidal and are actively working on fission; since the proportion of renewable sources is steadily increasing;and since political motivation rather than technical considerations are the main obstacles to moving to a renewable portfolio, I am at a loss as to why you think we are unable to solve energy problems.

    Maybe the new annual question from the Edge will cheer up the OP......

    John, it will be nuclear fusion, not fission to power the new world here. I have made several topics and posts on this and why it is so. Fission is ridiculously dangerous to the Earth. For the near future it will be hot fusion. Not too sure that cold fusion is even possible.

    Although, ironically, because of that, nuclear power is the safest form of energy we have.

    Fusion will be far safer, and there will not be radioactive waste.

    Not quite none: Fusion Reactor Waste

    But it will certainly be less of a problem.

    However, it is still not clear if a fusion reactor can be an economical source of power. (Or even a source of power, period.)

    Strange, that was older technology here is the new stuff, but the US department of energy also has a unique technique based on similar chemical reactions.

    In the deuterium-tritium (D-T) fusion reaction, high energy neutrons are released along with helium atoms. These electrically-neutral particles escape the plasma contained within the magnetic fields of the tokamak and are absorbed by the "blanket modules" of the surrounding walls. If these blanket modules contain lithium, a reaction occurs: the incoming neutron is absorbed by the lithium atom, which recombines into an atom of tritium and an atom of helium. The tritium can then be removed from the blanket and recycled into the plasma as fuel.

    Blankets containing lithium are thus considered "Breeding Blankets". Within the fusion reaction, tritium can be bred indefinitely. Once the fusion reaction is established in the ITER Tokamak, deuterium and lithium are the external fuels required to sustain it. Both of these fuels are readily available.

    Deuterium can be supplied by industry. Lithium is plentiful in the Earth's crust: if fusion were to provide electricity for the entire world, known reserves of lithium would last for at least one thousand years.

    A future fusion plant producing large amounts of power will be required to breed all of its own tritium. ITER will test this essential concept of tritium self-sustainment.

    Interesting. Do you have the link to that?
