Spoken like someone who has never had a surprise maintenance issue pop up unexpectedly that costs multiple times your monthly mortgage.

To get a townhome in the bay at ~2k a month is a complete outlier with respect to rent. I live in a similar COL area and the cheapest you could rent that kind of space is for ~3.5k monthly in the present market.

The car argument is not good. Anyone can buy and operate a car immediately on private property without any interference from government in the US.

Did you actually read your “source”? The article claims a lot but offers no substantiation to many of the claims.

Stratasys’ J850 totally has this capability. Full color printing with variable durometer elastomers.

Aviation regulations are written in blood. There’s a reason general aviation is stuck with technology developed in the 50s and 60s: innovating is so expensive from a compliance standpoint and production volume so low that new technologies enter that space at a glacial pace. A new Jet-A burning piston engine is only available in airframes that cost $1M+ and the cost of retrofitting in older airframes is prohibitive. If we weren’t so restrictive on the regulations, capitalism would offer a solution at a vastly reduced price point. So, would you rather have less provably safe aircraft, leaded avgas, or the complete prohibition of aircraft that make up the vast majority of the GA population?

I think I should have said “optic” in place of “lens”. The crystal is the portion that is being oscillated to divert the beam. It could be that this is exactly the same principle being used by the referenced experiment but with much higher powered acoustic equipment.

Doesn’t an AOM typically have a lens?

Revit is a pretty commonly used architectural tool now.
