Apologies for skimming through it because most of it was explaining the concept and process of which I am well familiar with. So it is possible that I missed it. If so , please give me a time stamp and I will make sure to watch it.

Dont get me wrong. This technology is exiting and I am very interested and excited about it, 

But,. And there is always a but. What abut the economics? Sure you can produce net electricity, but at what cost? How is it going to be competitive with other renewables , Cost per Kilowatt hour? 

IMO, perhaps in the future but not now.  But I hope I am wrong.  

Thought it would be amazing, I seriously doubt we are within a decade or two, of being able to generate power with fusion technology, on an economic scale that makes any sense. Hydrogen may be closer. 

Ever since I was a kid (there were wild dinosaurs and Raquel Welch) practical fusion power has always been "just 30 years away".

 

If it really does work economically it's going to be a game changer.

 

So far nobody has been able to sustain a fusion reaction for even 10 seconds . So far they have been able to be net positive in energy output but only if not counting the energy used to start the reaction (which is a millions of times more) .

I very much doubt i ever witness a actual fusion reactor in a commercial large scale energy solution. I am not even sure that is will actually be possible in total.

 

C’mon guys, I saw it in a YouTube video !

Yes, Fusion generates only heat that is used to boil water and run a generator exactly the same way as coal powered electric generation.

So you need a very large heat exchanger to bring the heat into the water and heat it to a 500 Celsius while all the fusion chambers are all very small and around that heat exchanger are super strong superconductor magnets that must be cooled far below the boiling point of liquid nitrogen.

So even if all technical problems are fixed the technical solution is super expensive and can't be used for commercial mass production of electric.

If we find superconducter that tolerate higher temperatures or find a solution without strong magnetic fields than it might get cheap enough but not with the current approach.

Yes it is always the same 30 years away since the 1960s

Same era for me, hence my dino and Raquel reference ???? 

 

 

Released in 1966 ???? 

 

Meanwhile, millions of us around the world, myself included, are already using fusion power for our home energy requirements.

 

It's just that the energy source is 93 million miles away and the energy transfer system is a little inefficient.

Meanwhile climate change has always been 10 years away from killing us all.

And that 10 years since the late 1990s....Forgot when was it Bangkok will be meters under water? 2015 I think

And you can all argue against solar power in Germany in January, but a shopping mall in Thailand which opens 10 or 11 AM is the prime example that makes sense...no expensive grid to transport the solar energy, produced exactly when it is needed....on a cloudy rainy day when the solar doesn't work well the ACs use less power.
