    I don't know if you all have seen or researched this yet, but it sure looks like it has potential. Electrical potential.

    I hope so. But it feels like I have been hoping so for most of my life; perhaps since I first saw an experimental fusion reactor on Tomorrow's World. I get the impression fusion power is always 50 years away.

    did that large experiment in California, the multiple lasers aimed at a small deuterium ? sphere-like target, did it fail ? or not yet complete ?

    ok i found this: National Ignition Facility - Wikipedia, the free encyclopedia

    As of October 7, 2013, this facility is understood to have achieved an important milestone towards commercialization of fusion, namely, for the first time a fuel capsule gave off more energy than was applied to it.[3] This is still a long way from satisfying the Lawson Criterion, but is a major step forward.[4]

    this may be a less biased article. of course it could be the very same info made from the ITER website.

    even in the Sun the H+H -> He fusion reaction only occurs in the core, the outer layers not hot enough or dense enough. a extreme engineering task to create the 'box' to encase this kind of energy.

    The idea is to use Hydrogen isotopes. Tritium is rare here on Earth, but deuterium and lithium are plentiful.

    "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."

    Now there has to be a lot of heat generated for this. Around 150,000,000 degrees C. Correct me if I am incorrect but I believe in fusion bombs, it was nuclear fission to do the igniting. We have seen plenty of the destruction fission can have though, so here the heating will be from several other sources, including microwave energy.

    Meteor Wayne said "20 years".
    The last I read the iter folks are hoping for completion circa 2028--------14 years(?) unless they are overly optimistic.

    Here is another approach from the US department of energy - http://www.iter.org/newsline/-/1884

    The first breakthrough comes from Sandia National Laboratories (the same engineers who brought us the fanless heatsink). At SNL, a research team has been working on a new way of creating fusion called magnetized liner inertial fusion (MagLIF). This approach is quite similar to the National Ignition Facility at the LLNL in California, where they fuse deuterium and tritium (hydrogen isotopes) by crushing and heating the fuel with 500 trillion watts of laser power. Instead of lasers, MagLIF uses a massive magnetic pulse (26 million amps), created by Sandia’s Z Machine (a huge X-ray generator), to crush a small cylinder containing the hydrogen fuel. Through various optimizations, the researchers discovered a MagLIF setup that almost breaks even (i.e. it almost produces more thermal energy than the electrical energy required to begin the fusion reaction).

    Probably more significant is news from the Joint European Torus (JET), a magnetic confinement fusion facility in the UK. JET is very similar to the ITER nuclear fusion reactor, an international project which is being built in the south of France. Whereas NIF and Sandia create an instantaneous fusion reaction using heat and pressure, ITER and JET confine the fusing plasma for a much longer duration using strong magnetic fields, and are thus more inclined towards the steady production of electricity. JET’s breakthrough was the installation of a new beryllium-lined wall and tungsten floor inside the tokamak — the doughnut-shaped inner vessel that confines 11-million-degrees-Celsius plasma (pictured above).

    I always thought it looked like HR Giger designed it.

    That's what I thought it was on first glance!!!
    a new giger picture!!
