    It's been "very close" for the past 20 years. And in another 20 years, it will no doubt still be "very close". For example, the European ITER facility is optimistically predicting to have sustained fusion going by ... 2035. That's not even an actual electric power generating facility, just a demo that fusion can get more energy out than put in.

    Then, even if it does, works, it won't be able to compete economically with any form of electricity generation. Costs for ITER are already around $25 billion and climbing.

    What's really interesting is that we cannot sustain a fusion reaction unless we use an atomic bomb to trigger it.

    Solar energy is weak and unreliable. It will never power an advanced society.

    Private companies like Lockheed are getting involved and achieving dramatic results. A group at MIT is also achieving dramatic results by working on small scale reactors. If the government took all the money it spends on so-called "clean energy," fusion would be achieved quite soon.

    Solar power satellites.
    Generate power 24 hours a day, beam it down to Earth.
    We could build them on the Moon. Plenty of silicon and aluminum.

    Humanity is very close to achieving a nearly endless and clean energy source.
    We've been 20 years away, for at least 30 years now
    .
    But they don`t want to hear that. Nor do they want consider that the biggest obstacle is for how long we can maintain a plasma at the temperature required while compressing it to a density ~ 8 times higher than depleted Uranium at the same time The world record for that is about the same as for how long a human can hold his breath and we need that time to be 24 hours/day each and every day.

    Getting fusion to work would be cheaper and better in every way.

    It doesn't need to be compressed "to a density ~ 8 times higher than depleted Uranium." Plasma is even more rarefied than a gas. It's not where near the density of a solid.

    Having a plasma is one thing, fusing it requires a high (!!) density.

    It doesn't require the density of uranium. You obviously don't know what you're talking about.
