You're a wonderful communicator Dr Cowley. No doubt that you apply that same passion to your new profession as a scientist. The fusion industry is lucky to have you.
Everyone LOVES your t-shirt. But I say, TAKE IT OFF! You'd look awesome in just a cape, the symbol of power and prestige. A flowing cape will make you appear larger and more imposing, potentially intimidating those evil anti-science villains. However, once they catch wind of your superior cognitive abilities, you’ll need to adopt an alias to safeguard your secret identity. Copilot suggests "Doctor Divertor" and "Magnetic Maestro." :-)
A very clear presentation. Perhaps Dr Cowley can tell us how the plasmas will be controlled in the DT operation when the high energy neutrons will knock the hell out of sensors and insulators in a matter of minutes?
While mixing tokamaks and stellarators might bring the best of both, care should be taken not to bring the worst of both. To be fair, studies at the University of Auburn Compact Toroidal Hybrid (CTH) experiment have proven it's possible to reduce disruptions.
Don't the toruses become radioactive from neutron bombardment after some time? Would that be considered nuclear waste? I have been asking this question since 1972
Yes, 'linings' may be replaceable. At one point it was said that a new tokamak design - if successful - might involve burying upwards of 10 tons of SS316 every year or two. The ideal fusion would have an 'aneutronic' burn (it would yield no neutron flux). Some efforts are in this direction. But, the environmental conditions to fuse 'proton and boron11' are far more demanding than to fuse duterium-tritium (possibly unattainable), and the energy yield of that reaction is much lower, too.

Yes, I definitely would like to see their fusion approach covered. I hear they have the highest plasma heat amongst all other private fusion companies.
One thing that I have never had explained to me is what happens when a 100 million degree photon hits the container wall, is the energy absorbed and diffused into nearby atoms or does that atom get blasted off the wall and into the chamber which I assume would prevent this type of fusion?
The issue aren't the photons, but the 14 MeV neutrons, which will displace and activate the atoms in the wall. That's why research on the first wall materials is so important. Although everyone in the fusion community is aware of this, there hasn't been enough investment on this, and that's why 14 MeV neutron sources are so badly needed.
congrats!! ... doctor Cowley Finally, the U.S. govt is recognizing the importance of fusion research. In the past, it did the equivalent of giving a nice corner-smile-glance, but never really dealt with it as a serious alternative energy generation method. If we can crack this nut, we'll never want for electricity - we'll always have more than we'd want.
It is all about containment….. The sun uses the force of gravity to contain the fusion reaction and only energy in the form of radiation can escape the force of gravity. Whilst here on Earth the fusion reaction is contained by the magnetic force. The question must be how the energy from the fusion reaction is captured and released from the magnetic confinement. It seems an impossible task…..
Congrats DR. Cowley!!
I've only watched a few FIA news updates. I do get some sense that we now have a maturing 'industry' with mature information exchange. Great news!
You're a wonderful communicator Dr Cowley. No doubt that you apply that same passion to your new profession as a scientist. The fusion industry is lucky to have you.
It's great to see you develop your confidence with presenting through watching the videos you produce, and also great news on earning the Doctorship!
Brilliant diction and projection Dr Cowley. It is a delight to listen to you.
Thanks for bringing us to speed, and congratulations Dr. Cowley, you have a bright future in a very important field.
Congratulations Dr. Cowley! Thank you for investing your time for this FIA update videos.
Congrats of the Dr! And I love the shirt.

Congratulations on the degree!
It is great to see that scientific community increases its ranks with well prepared people like you. Congratulations Dr. Cowley.
Congratulations Dr. Cowley!!!
Thanks Doctor 🎉🎉🎉

Congratulations! I'm sure you have a great career ahead.
Thanks Dr.
Congrats!! You’re the best!
Don't the toruses become radioactive from neutron bombardment after some time? Would that be considered nuclear waste? I have been asking this question since 1972
.
The answer to this is yes, and the activity will be high enough to question whether repair by remote vehicles will be possible.
@@johnh6245 .. I visited the Princeton tokamak in 1972 and they avoided the question

Who knew doctors could be so smoking hawttt 🥵🌶♨?!
Could you cover Lawrenceville Plasma's DPF device?
Yes, I definitely would like to see their fusion approach covered. I hear they have the highest plasma heat amongst all other private fusion companies.

I am hopeful by the time you are in your 80s progress will have been made.
Congratulations on the Doctorate - remember, you can only use 'Trust me I'm a Doctor' a few times :-)
So then is it a “Stellamak” or “Tokarator?”
Tokerator???
Thank you Dr. :) Sub'd :))

Congratulaions on earning your PhD, your license to practice as a scientist (as I was told myself once long ago).
