So if we took all the non solar matter in the solar system we would still not have enough matter to build a full Dyson sphere

But we could build a Ringworld, and then we can spin it for gravity, add shadow squares for a day-night cycle, and not have to rely on artificial gravity generators to prevent us from falling into the sun!

True, but if we expanded our scope to all the space dust in the cubic light-year the sun occupies the center of, we will have enough material to build between 10-29 solar systems, complete with their own stars, so that's probably enough material.

To collect the space dust, we need a Dyson vacuum.

Depends how you do it, if its just a thin reflective foil focusing light on a few collectors then we could probably do it inside a century on just the worlds current production capacity. (baring actually getting all the foil there and engineering collectors and so on, just talking making the foil itself here)

I think that would just make a really big solar oven.

Thats the basis of quite a few solar power plants.

Welcome to the discussion of US Politics!

Rules:

  1. Post only links to articles, Title must fairly describe link contents. If your title differs from the site’s, it should only be to add context or be more descriptive. Do not post entire articles in the body or in the comments.

Links must be to the original source, not an aggregator like Google Amp, MSN, or Yahoo.

Example:

  1. Articles must be relevant to politics. Links must be to quality and original content. Articles should be worth reading. Clickbait, stub articles, and rehosted or stolen content are not allowed. Check your source for Reliability and Bias here.
  2. Be civil, No violations of TOS. It’s OK to say the subject of an article is behaving like a (pejorative, pejorative). It’s NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
  3. No memes, trolling, or low-effort comments. Reposts, misinformation, off-topic, trolling, or offensive. Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
  4. Vote based on comment quality, not agreement. This community aims to foster discussion; please reward people for putting effort into articulating their viewpoint, even if you disagree with it.
  5. No hate speech, slurs, celebrating death, advocating violence, or abusive language. This will result in a ban. Usernames containing racist, or inappropriate slurs will be banned without warning

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

That's all the rules!
