To help fusion energy observers get a better handle on our industry’s progress, I’m detailing the six steps every fusion company must take on the path to delivering power competitively. Today, I’m digging into the second step: get your fusion fuel hot enough. For fuel, fusion energy requires a very energetic cloud of charged particles called a plasma. Step one is making one – that was the previous milestone. Step two, if your fusion machine is able to heat a plasma up to 10 million degrees, it shows your machine has some promise to make a plasma that could someday sustain fusion reactions. Many different types of machines have crossed this threshold, including the type we’re using at @CFS_energy, called a tokamak. We’re sharing this because we want to help people watching our industry — investors, the press, science fans, policymakers, and increasingly the general public — appreciate the real progress while not falling for empty hype.

Not trying to be excessively combative but I think a prior step should be show you have affordable and reliable fuelsources. For example, the Tritium to start these factors is neither cheap nor plentiful, last I heard. And anybody using Helium-3 has it worse. Your thoughts?

Nice! Also would be great to highlight the engineering problems to tackle, the different approaches out there, and where everyone is with them. Yeah, the nerdy parts.

Not wanting to make you sound wrong but is it logical to demand temperatures many times hotter than the sun for a reaction that happens at temperatures far less in the sun? Temperature wasn't even a factor in the original Lawson's criteria. I think it is still too early to gatekeep methods to burning plasma until at least we have a process that yields consistent and sustained Q>1. Till then, all our methods (yours inclusive) are 'hype', even though you have more dollars than we do. 😉 Go easy, Bob! 🙂
