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?

There are several challenges, and our SPARC fusion machine is designed to address most of the ones on our list. In parallel with SPARC, we'll pursue tritium research to develop ARC's tritium breeding technology. This @CFS_energy blog post has details: blog.cfs.energy/how-863m-in-…
Nice. Thank you.
