US DOE - Fusion Ignition

My immediate thought. Pumped for when doc oc gets out here
 
Try to enlighten us. Seriously, not being a jerk. We’re not all nuclear physicists but we are mostly college grads.

I’ve read 3-4 stories about it, what was I missing that makes this an impossible tech for even another few hundred years? Maybe I’m an oddball for caring about the human race after I’m gone. It’s not like I’m expecting it next year.
I need Neil DeGrasse Tyson to break it down for a dummie like me

Don't listen to the haters. There is a lot of concern that the method used to create the reaction will not be scalable to actually use it for energy production. That said, it's still something humans had never been able to achieve until now, so it's still a pretty big frigging deal for the science.

In the reaction they got more energy then they put in.

But the lasers they were using operate at 1% efficiency, so they used 100 times more power getting enough energy into the reaction in the first place.

Not to mention the reaction net gain was not converted back into electricity at whatever efficiency loss it has.

Basically if I'm calculating it correctly, the gain they needed off the reaction just to make it energy neutral needed to be 187 times more then they got, assuming 100% of the extra gain was converted directly back into electricity.
 
I know a scientist at Livermore extremely well and have asked about this and other research going on at the lab. They've basically answered nothing for classified reasons. From the small amounts I have gathered. This has FAR more implications for our military and national defense than it does moving us towards a greener grid system.

I haven't gotten my CF fusion degree yet, but I assume we're still just using a steam turbine to generate electricity?

Those two things go hand in hand.

Our national defense is weakened both by being dependent on ****** countries in the middle east for oil as well as by the effects of climate change that are likely to increase conflicts around the globe as time goes on.

But yes, if we could develop compact fusion reactors they could power all sorts of things, from ships to larger aircraft.

Yes, even if someday we are able to harness the powers of the sun itself, we'll still be using it to boil water to generate our energy.

I’m not surprised by this.

Didn't know they had any scientific stuff in Livermore. Town of 400 some by Fort Dodge must be rockin'
 
From what I've read and heard about it, this sounds to have more impact in advancement of weaponry than power production. The process that they went about it with lasers makes it difficult to make a constant reaction rather than just a quick single burst. While cool, it isn't the game changer that many are hoping it to be.

While an incredibly cool scientific success, I'm not sure that we're all that much closer to that "unlimited clean power" that many news outlets are making this out to be.

So....we get to see Real Genius finally play out?

Doesn't everything?
