Reply to [OC] Wind Speed versus Fossil Fuels by Barra79
It looks like there might be a hard floor of 9GW fossil generation that is more apparent at higher wind speeds. Either turning the fossil plants completely off is not allowed by contract or law maybe? Or this grid needs the inertia of these fossil power plants? So, the apparent upswing in the curve fit at very high windspeeds is a bit misleading. Also, extremely high winds might be associated with cold fronts / snaps that cause wind farms to feather their turbine blades or electricity demand to spike.

Well if you count Supernova explosions scattering heavy elements into the universe, even then it's not renewable. You know some way of continuously making uranium 235? If you do, the nuclear physicists would really love to know it. But back in the reality that the rest of us live in, there is only a limited amount of fissile fuel on our planet.

No, they're conserving more land than they're actually using for these things. A lot of the land isn't even forrested to begin with like you're trying to make people believe. And some of this supposedly forested land is actually for Timber production, not entirely Greenfield areas. So you're leaving out a lot of the story and it's clear you have an agenda that you're trying to push. People aren't buying it.

You are absolutely lying about what these projects are doing:
"Syncarpha’s 7-MW project in Old Town will be leasing land from the city to construct an array on Dewitt Airfield. This land, currently vacant, unused and untaxed and with little agricultural value, will now be a stream of rental income for the city over the next 20-years.
In Readfield, Syncarpha and a property owner struck an unusual agreement, whereby the owner will put approximately 75 of 95 acres into conservation. The remaining acreage will be leased to Syncarpha for the construction and operation of a community solar farm.
The power generated by this array will benefit households in the same utility “load zone,” ensuring that the land is not subject to permanent commercial development. After the operational life of the solar farm, equipment will be removed and the portion used for solar will be put into conservation as well.
Syncarpha has purchased rocky land located next to a highway in Augusta to build a solar farm, but will not develop the entire parcel. The project is donating approximately 10 acres of woodlands to the Sportsman’s Alliance of Maine, its largest sportsman’s organization, for the alliance’s outdoor education center."
"Five years in the making, the 152-megawatt solar farm is one of many ongoing renewable energy projects geared toward meeting Maine’s statutory target of 80-percent clean energy by 2030.
The land is owned by Bessey Development Co., a Hinckley-based, family-owned wood brokerage company, and has been in the Bessey family for more than five generations. Most of the land was previously used for commercial timber harvesting, and some of it was used by a tenant farmer to grow corn.
In compliance with the state’s conservation policies to reduce environmental effects, the company has conserved 1,875 acres — including 1,020 acres in what’s called the Unity Wetlands Focus Area, 324 acres in Readfield and 531 acres in Shirley."

Racking, anchors, clamps, etc are designed for high wind areas. Florida solar installations actually get beefier hardware than those in California because it's designated as a high wind area.

Yeah, isn't this the hypothesis about giving enough time, anything that is possible will happen? And even though it's astronomically unlikely to happen, a new universe bubbling up from a Quantum fluctuation and into an entirely new and separate universe could theoretically happen.

Reply to comment by hikingsticks in Eli5 why aren't gas only vehicles far more fuel efficient than before by Live_Strongerrr
Yeah, the ability to accelerate from a stop up to 5 to 10mph on electric only really boosts city fuel economy. For a conventional car or bus, this is where they have the absolute worst fuel economy gulping down fuel in 1st or 2nd gear. I'd also suspect that bus drivers taking off from a stop in a regular diesel bus would step on the throttle and cause the engine to run a rich fuel / air mixture. So the benefits accrue here as well in the fuel efficiency and maintenance departments.
Going forward, I'm glad we're seeing explosive growth in all electric buses and cars. They're vastly more efficient and simpler than a hybrid drive train, avoiding the tradeoffs between power and efficiency hybrids had to make. Hybridization was a great technology for its time but it's increasingly being supplanted by full electric architecture.

>but doesn't alter the thermal efficiency of the engine itself
Slight correction. Hybrids like the Prius use a slightly different engine cycle than pure ICE cars. Basically, the intake valve closes later in the Prius engine so the engine doesn't compress as much air as if it intake valve closed right after the intake stroke finishes. This means the expansion ratio is greater than the compression ratio, trading power for efficiency. The addition of 2 electric Motors helps make up for some of the loss in power. The electric Motors/ generators also allow the car to control the gas engine speed and not rely on the throttle so much to do so. This allows the car to run with the throttle more open and even wide open a lot more of the time. This reduces the pumping losses since the engine is not sucking air through a restricted throttle a lot of the time. To top things off, this also reduces pressure drop that would normally happen across the throttle in a conventional ICE car, increasing the air available in the cylinder.

But there's a similar situation going on with hybrids. The 2023 Prius gets slightly better fuel economy as the 2003 Prius. It's gone from a 1.5L engine to a 2.0L engine over that time. The 2023 is 350lbs heavier, explaining a lot of the stagnation in fuel economy.

Those high efficiency numbers are in lab conditions at ideal operating parameters. A lot of these high efficiency numbers come from test engines that are years away from being in use or are so exotic that they will never be used in a production car.
In the real world, car engines hardly ever operate at their maximum efficiency point. Add in idling, engine warm up time and the inability of conventional gas cars to recapture energy from regenerative braking and the actual efficiency is much lower.

Reply to My Personal Story About Challenger by MoabEngineer
I always had this memory of my kindergarten teacher setting up a TV in the class for us to watch something. I didn't really understand what was going on at the time. However, I clearly remember the teacher suddenly turning off the TV in the middle of whatever we were watching and announcing that we were all going to the playground right away. It always struck me as weird and we never got an explanation as to what happened.
It was only years later that I learned about the challenger explosion and the date lined up perfectly for when I was in kindergarten. I watched it happen on live TV when I was very young and never even realized it for years.

Reply to I think Velma was written badly on purpose. by 2Bit_Dev
Never assume malice when incompetence / laziness / greed are more than enough to explain things. Mindy Kaling hasn't been funny for years but she's well connected. Focus groups have at least passing awareness and interest in the Scooby-Doo franchise, especially in key age groups. Edgy reboots of popular IPs are the lazy way to tap into a preexisting pool of potential viewers. Streaming services are keen to follow the Disney+ model of throwing as much shit on the wall as possible to see what sticks. The entertainment industry has really lost touch with how the art and workmanship of writing / storytelling are crucial. Add these all together and it's more than enough to explain how Velma could get made.

Reply to Does preventing evaporation on canals and reservoirs increase the ambient dryness/negative environmental impact overall over the long term? by safdwark4729
Water loss from a canal is negligible compared to the amount of water in the air.
What's interesting is that the way we build canals and other similar structures that allow natural runoff to pool on their uphill side instead of continuing downhill has led to large vegetation growth:
https://m.youtube.com/watch?v=jf8usAesJvo
The water percolating and increase in transpiration from the plants in these areas has way more effect on the local climate than the evaporation directly from the canal ever would.
