For real this time, NSF, I swear it's the last time.

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

We already have a perfectly good nuclear fusion reactor about 93,000,000 miles from our planet. We just need to make better use of its output.
I mean yeah, we should absolutely be replacing as much fossil fuel use as we can with existing renewable energy tech. But there's no reason we shouldn't also be investing in fusion research, at least as far as I'm aware
Because bad actors like fossil fuel and car companies will say "look, the government is funding fusion. Don't make us go renewable now, just wait five years until fusion is here." You have to consider the political impacts pursuing research will have on society's perceptions. Even if you know your project is just a wild experiment that probably won't work, journalists won't.
You mean like exactly what they did to Nuclear power when Solar and wind were those experimental and untested at scale technologies?
They already do this fyi. Solar plants tend to use mirrors that concentrate light to heat water and turn a turbine instead of actual solar panels. Amazingly, iirc converting light into heat, the heat into steam, and then the steam into kinetic energy, is still more efficient than a normal photovoltaic cells.
And if you wanna go big you use liquid salt instead of boring old water.
The concept is viable. Just needs moar mirrors
Mythbusters used a lot of mirrors, and could not get it to work.

Sadly I believe they found adding more mirrors did not appreciably raise the temperature of the focal point. Diminishing returns and all. So unfortunately more mirrors is not the answer, more Lasers is!
Well seeing how you almost need the output of a Dyson swarm to make a Dyson swarm, cool glowy rock power and explodey gas power can and will work just as good. Especially for places that are far away from the ideal conditions to exploit solar energy terrestrially. Where I'm at we have to use literal piles of garbage to be able to get high enough above the trees to achieve sustainable output.
