They're the ones who did the actual testing/measurements. I had a box fan attached to a single filter (for wildfire smoke) but was unaware of how inefficient it was.
just to follow your logic. lets say I invent car. Corsi and Rosenthal measure it to discover how more efficient it is compared to horse, and from that point it's known as their invention
It's known as their technique (not invention) because it got popularized via of word of mouth. Same as the Fosbury flop or Larsen truss.
If you create some novel car design that gets discussed enough, maybe it will get popularized and get named after you. ie Bangle butt, for the E65 BMW 7 series.
Ownership is known - Microsoft/Disney/Warner. For them, it's probably not worth the lawyer time to try to sort out what stake and/or transferring the IP.
Ironically Microsoft's consolidation of the video gaming market might have a weird positive effect here. In cases where the ownership is disputed or split between multiple entities if Microsoft acquires all of them it gets intrinsically resolved
This only helps if they acquire every possible rights-holder who could have a claim. And even then there could be revenue sharing issues that make publishing anew impractical.
Based on Microsoft's acquisition spree, that seems highly likely. Revenue sharing I think at this point is just a matter of the correct SEC disclosures for quarter-end statements
If all you need is compute, than yeah, self hosting is easy. Otherwise, do you think just about every company under the sun is a sucker for being on the cloud? If it was so easy, companies would be either be constantly dropping prices to compete with all the self hosters, or new companies to fill in the price gaps.
I acquired a minisplit for $450 or so (labelled "For export only - not for sale in US or Canada", because it contained R-410 and doesn't meet the current efficiency standards) and installed it myself.
Getting a similar system installed would have been north of $10,000, and before anyone says "well, that would be a licenced HVAC installer", no it wouldn't - it would be a barely-trained person who is simply "supervised" by a licenced HVAC technician.
If it was so lucrative, wouldn’t more people set up shop undercutting the current offerings? Why not become an HVAC installer and make millions, if you’re really able to make $15k profit on a job you can turn out in a day.
The truth is probably more that the various money sinks in our society are starting to add up, things like healthcare, legal protection, licensure, compliance, rent (business or personal), even just having appropriate work vehicles, fueling them, compensating people for the time spent sitting in traffic to come across town to your house. Somehow you’re paying for all of that when someone’s livelihood is installing your mini split. A lot of those costs have grown faster than wages, if you try to point to a reason why it’s different today than 20 years ago. More people looking to make a quick buck without doing any work or providing any real value, and more people succeeding.
In my state (OR) it takes 4 years to become licensed to do the work for others but homeowners can do the work themselves.
My experience is that it’s not generally well understood how simple it is to install mini splits. The supply companies won’t sell to you directly outside of d2c web companies like hvacdirect
My state has a program where they give you big rebates but only if you use some one on their list of approved installers and since there aren't many installers it creates a big backlog. Homeowners who could install them themselves miss out on the rebate.
In Seattle, installing AC requires a refrigeration permit, which requires a refrigeration contractor license to pull and a licensed HVAC tech to install, which takes 4+ years of training.
It is expensive, but I think you're underestimating the costs.
If the AC catches fire because your electrician skills are bad, what happens? I guess you can rent a ladder if you need one, but they're at least $200 if your split is on the second floor and ladders can be deceptively tricky, and load ratings must be considered. Condensation can kill you and be an extreme cost with mold. Your first mini split is going to take a real long time to install, I promise, assuming you size it right. There is a non trivial risk to life and limb.
This is one of those "Reality has a surprising amount of detail" things.
If you're not comfortable with the electrical work, hire an electrician.
Of course don't DIY it if you're not comfortable, but a simple exterior wall install is fairly straightforward. On a second floor install, (with the condenser on the ground) you only need a small egress hole you can drill from the interior. You'd need a ladder just to secure/cover the lineset.
I'm sorry, but that's not a fence, it's just a vertically mounted array. Would OP really have built a regular fence there?
It'd probably be less labor and material intensive to just build a single structure holding the entire array using much longer rails instead of setting posts and rails every 6-7 feet. To keep costs lower you could also go with a string inverter instead of the ~$1500 you'd need for microinverters.
Pricing conveniently doesn't include the panels, so you just have a set of posts and some horizontal racking.
