U.S. physicists rally around plan to build fusion power plant

Serious question: how does an article like this get written without mentioning SPARC[1] once? They&#x27;re hardly secretive, they&#x27;re MIT&#x27;s people, they&#x27;re moving on a plan to get results in ~5 years, and they&#x27;re talking about the same kind of things: tokamaks, better computer modeling, and easier to make higher temperature superconductors for stronger magnets.<p>I&#x27;m just a layperson, I only know pop science level stuff here, but they seem clearly like the best game in town -- so, seriously, can a person in the physics world shed some light on why they aren&#x27;t at least a small part of every article about fusion, but ITER is?<p>1 - <a href="https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;SPARC_(tokamak)" rel="nofollow">https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;SPARC_(tokamak)</a><p>(And, for those with an interest who still haven&#x27;t seen Zach Hartwig&#x27;s absolutely excellent 2017 talk: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;L0KuAx1COEk" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;L0KuAx1COEk</a> -- watch it!)

This is more like &quot;Fusion physicists rally around plan to improve message asking for more money&quot;. It&#x27;s not like there&#x27;s a serious plan to build a power plant.<p>Except at Lockheed&#x27;s Skunk Works, which is quietly plugging away on their own.

Are at an inflection point for fusion power? With interest and funding for it finally gaining steam? I’ve noticed several announcements about independent efforts this past year [1–6] but not sure if (a) it’s always been this way or (b) my view is skewed by HN.<p>[1]: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=21806334" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=21806334</a> &quot;General Fusion&quot;<p>[2]: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=23979608" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=23979608</a> &quot;ITER&quot;<p>[3]: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=24629828" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=24629828</a> &quot;SPARC&quot;<p>[4]: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=24986528" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=24986528</a> &quot;MAST Upgrade&quot;<p>[5]: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=25209666" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=25209666</a> &quot;NIF&quot;<p>[6]: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=25261068" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=25261068</a> &quot;KSTAR&quot;

2040s? 20+ years from now!?! Too fuckin slow!!<p>For all Musk&#x27;s faults, he recognizes such timelines are untenable, and pushes people to do the &#x27;impossible&#x27;.

Ok, say I&#x27;ve got a new design for a fusion reactor, but it takes me 5 years to convince anyone that it&#x27;s worth investigating.<p>Fusion power has been set back 5 years.<p>Someone please help me evaluate my design. Please!<p><a href="http:&#x2F;&#x2F;www.DDPROfusion.com" rel="nofollow">http:&#x2F;&#x2F;www.DDPROfusion.com</a>

Meanwhile, reportedly China has already built one and is testing it now. So the USA is 20 years behind?

The big problem with fusion is the enormous costs associated with producing energy. I guess we need to generate large amounts of energy to justify the expenditures. Based on that, I believe that China is the only country that has both the money as well as the large-scale need to make fusion practical.

&gt; to prepare to build a prototype power plant in the 2040s<p>this doesn&#x27;t seem terribly &quot;ambitious&quot;

How much of the excess renewable energy is being wasted rather than stored? Maybe fuel generation like hydrogen or ethanol, or kinetic can help make nuclear less crucial?

I think that solar&#x2F;wind + battery (e.g. Tesla Megapack) will make fusion irrelevant.

Serious question: what happens after? Will it literally be &#x27;free energy&#x27;? And are we ready as a society to handle this properly? How do we ensure that this will benefit everyone and not create an enormous imbalance by itself?<p>I guess the existing economics will be broken at some point if the cost of everything will be driven down in such a way. Are there any articles&#x2F;works that explore this issue?
