Well Neil DeGrasse Tyson went on Fox Business and talked about this like we have achieved net energy gain in a power plant, when in reality NIF uses 100x more energy than they got out of the pellet. He makes it seem as if we have solved fusion, which I think is pretty dangerous, as any viewer who believes what he says could start to believe we don't need to think about renewables anymore.

The following is a partial transcription of what he said:
Neil: Right at this moment I don't think people know for sure what the announcement will be, but if the secretary of energy is giving the press conference, everyone I think is thinking that we finally can get out more energy than we put in, and that is the key..
(Neil describes fission versus fusion, and (weirdly) magnetic confinement fusion, even though NIF is inertial confinement. It really feels like he doesn't know anything about NIF.)
Host: alright so lets say we've overcome some of those challenges and finally created more energy than we put in to the experiment.
Neil: That's it.. you got it. so now it's up to the engineers. Once we get the physics figured out, which it seems like we have, then the engineers say can I make that smaller, can I make that portable, would it fit in to a car? or is it only the size that might power a city? there are places that don't have access to energy... either oil or sunlight for example... so this would be transformative to civilization, and I see it akin to the transition from horses to automobiles, which happened in a matter of a couple of years, because we got the physics figured out for engines, internal combustion engines, when that happened you couldn't give away a horse, yet we were riding horses for thousands of years, building civilization literally and figuratively on its back. so my analogy to that is, we've been digging fossil fuels out of the ground for 150 years...
Host: How long will it take to heal the planet from any harm that we've done to ourselves?
Neil: Yeah here we are harming a planet that was itself trying to sustain us. by doing that you've sewn the seeds of your own extinction. and so the planet will heal, slowly. a lot of the carbon is taken up in to the oceans, so if you start dropping the carbon in the atmosphere, the oceans will equilibrate with that, so it will take time. but now is better than any time later than now, so oh yeah... I'm giddy.
Host: I can't wait for my fusion engine.
Neil: It's a pivot in civilization.
- geysersam 4y agoJesus Christ. "Now it's up to the engineers." It's been that since the 50s.
- Gud 4y agoIt’s finally moving forward though. Commonwealth Fusion Systems has a plausible design.
- thayne 4y agoI think the GPs point is that "it's just an engineering problem now" doesn't mean it is easy to solve. It's been "just an engineering problem" for a long time. Of course, new physics discoveries can make the engineering problem easier, but that is true of practically any engineering problem.
- Gud 4y agoI understand that, but a lot of progress has happened just in the last 10 years, especially with regards to superconducting magnets which are vital for the magnetic containment. I see so much negativity regarding fusion power when so much is happening it’s important to show all the positive things happening
- TaylorAlexander 4y agoOh I am a huge believer in CFS and their SPARC system. I’ve watched every hour long lecture they’ve posted on YouTube. My whole issue is that this announcement from NIF is not some kind of holy grail so many in the news are making it out to be. It’s a positive step but Neil DeGrasse Tyson is talking about “now engineers need to figure out if they can put this in cars” and it’s like… no that’s very much not the next step. In fact NIF isn’t really trying to be a path to a functional power plant so much as a weapons research system that happens to produce research which might be useful for other systems. I just really feel like NdT is really misrepresenting the importance of this specific announcement. In particular he’s conflating Q plasma with Q power plant. The NIF draws about 100x more power than it delivers to the target so if they actually tried to harvest the energy they generated they’d be losing 99.4% of what they’re putting in, at least according to comments I’ve read on HN about it. NdT makes it sound like they have actually gained energy when they are two orders of magnitude away from doing that at NIF.
