Ioannidis published a journal article with what many considered an ad hominem attacks against a graduate student. He later withdrew that portion of the paper, (somewhat) in his defense.
Maybe this is obvious, but make sure to check your rate structure with your energy company. Just because market prices are high later in the day doesn’t mean that’s when your prices are highest.
While this is true for much of Texas. I happen to live in a city that still has a public operator. So we just get more generalized flatter rates. I haven't looked into the details of my plan closely in a while as a result though, so you might be right.
En masse though, it seems not ideal from a cost perspective the way things have been scheduled up until now. I'll give them the benefit of the doubt that it might be adjusted better in the future.
Sorry for the late reply. That all makes sense. And it’s definitely possible that your power company’s rate structure isn’t really optimal for them (or the market, or you). Electricity rates seem to be generally messy and a mix of big compromises, in my experience.
Yes, because there is a lot of space there and the sun shines a lot. But they are not more efficient that installation outside of deserts which was the claim made by the comment I was replying to.
Grid following inverters can do something similar, although their response time is usually limited to the grid operator's automatic generation control (AGC) communication cycle, which is typically on the order of 4 to 6 seconds. And this requires plant controllers, and markets/contracts, to be setup for it.
See https://www.nrel.gov/docs/fy24osti/86932.pdf. It deals with estimating reserves from these types of resources, but also talks a bit about general considerations, and references other good papers and demonstrations.
There’s a bit of irony in the second reference, as the author ended up with some controversial work related to COVID-19. He co-authored a study that was widely cited to downplay severity of the pandemic, but was also heavily criticized for poor methodology (and later I think firmly found to be very wrong). He also published a paper with personal attacks of a grad student that had disagreed with him, which is probably not in the spirit of encouraging constructive science.
I never wear my rings places where I don’t also bring my fingers, and rings don’t leave oily prints like my fingers do. Sarcasm aside, I’m not sure how this is a security risk.
In 2014[0], someone stole the German Defense Minister's fingerprint from a picture. We are well past the point where you can assume your biometrics are secure.
I guess you can go ahead and take "criminal mastermind" from your CV! Why would I think that a physical 3D object with the pattern of my fingerprint that can be carried around and held up to anything might possibly be a security issue? Nope, I can't think of anything...

Careful, your sarcasm is dripping!

Have you looked at the image of the ring? How do you plan to scan that anywhere?
I was going to say the same thing. A poorly maintained chain wears and “stretches,” and in turn wears gears faster. There’s no need to intentionally wear out components for better exercise - just ride a longer route faster, throw rocks in a backpack, etc. A poorly lubed chain only adds maybe 5-10 Watts, which is not much in terms of fitness improvements. And a worn chain and drivetrain is more prone to slipping or breaking, which is a good way to get injured.
Edit: I just realized nsteel said pretty much the same thing below.
The web-based “history” tool’s content and usability has been significantly reduced, as well. You used to be able to view and download a lot of detailed hourly data - now it’s reduced to things like daily summaries when selecting long time ranges.
Paul Gipe’s website [1] is always worth checking out when it comes to unusual wind turbine designs. He knows a ton about the history of wind energy, and lots of things have been tried before.
And this NREL report [2] is also relevant. It reviews a number of rooftop wind projects. None of them met their energy goals. And the report also recommends sticking with 3rd party certified horizontal axis wind turbines (but those still underperformed because rooftops are not great for wind energy…).
