When I was in college 45 years ago all the experts were saying that a working commercial fusion reactor power plant was only twenty years away. That is exactly what is being said today. I seriously doubt that one kilowatt of power will be produced from such a reactor in the remainder of my lifetime.

The concept would need very large funding but IMHO it is possible.

Nuclear fusion is what is happening in the sun. Fusion requires millions of degrees. No substance on earth can sustain those temperatures. We have produced nuclear fusion here on Earth in the Lab for a few billionths of a second. The plasma must be contained in a magnetic field; the Russians used their "Tokamak" some decades ago with some success.

As we have discussed on these forums over the years--Why would we want nuclear fusion here on Earth or in our spacecraft. Fast breeder reactors should be re-visited. Since we have had catastrophic events with our Fission reactors we should be very wary of moving to other reactors that are many more times difficult to contain.

ITER has already cost 15 billion dollars without producing a single watt of electricity.

ITER is using magnetic confinement fusion. IMO inertial confinement fusion would be much more interesting on a large scale.

Inertial confinement is searched at Livermore National Laboratory as a military program producing micro H explosions.

Where I'm going to would be an inertial confinement fusion process on a large scale i.e. confinement tanks the sizes of towns or cities. Appropriate sites for this would be deserted areas such as the Sahara desert.

There are many political obstacles to such projects.
DESERTEC was a large scale project that would harness energy from the sun.

Fusion has been around since "Ivy Mike"
Its just not controllable
Life is what you make of it :-)

When i'm good i'm very good , but when i'm bad i'm shi#eloads better ;-) In't I " buttercups " p.m.s.l at authoritie !!;-)

We have a huge fusion reactor at a safe distance, the SUN. Last year 8% of electric power in Italy was produced by photovoltaic panels. This, plus hydroelectricity, wind power and a little geothermal production brought Italy's renewable power production to 40% in 2013. This is the way to go. We need to build a smart electric grid and develop electricity storage to use at night.

I have no doubt that fusion power generation will develop in the not too distant future.
I also see no reason to hide any future fusion power plants in the Sahara.
Fission power is a much more dangerous technology than Fusion.
Most Fission reactors often contain enough fuel to last a year or more.
Most designs for Fusion reactors call for but small fuel pellets, or a small quantity of gas, to be ignited at a time,
or a continuous process of balancing the plasma by addition of fuel, and scavenging of by-products.
My favorite Fusion research project is http://lppfusion.com/
They don't have a gofundme page, but they do accept donations.

You really have to stop posturing as someone who actually knows everything.

Could you be more specific? Or are you a Donald Drumpf?

Wow.. Thanx for that link Gordon. I wonder whether the concept has already been realized.

A fusion experiment only produces 14 MeV neutrons. To get some electricity, you must use them to heat water and produce vapor, which moves turbines which power alternators. There must be a simpler way to boil water.

Not if you want to eliminate the carbon footprint. Otherwise burning coal comes to mind.
