How do electric vehicles penetrate the market during record low oil prices?

12,000/59,000,000= 0.0002 = 0.02%

In the documentary I saw about him, he has a successful (relative) launch and touchdown. That steam rocket is basically a water heater. They crank the heat up the night before, then by launch time it's built up enough pressure. As you pointed out, it's only powered on whatever energy of steam is stored at takeoff. He knew that thing would never get as high as he claimed.
I don't think this guy cared two shits about the flat earth movement. He just used it as a vehicle for self promotion and funding his hobby. -
From what I just read, the distinction between the two has to do with how the act. In low populations, locust act the same and are generally indistinguishable from grasshoppers. However, in higher populations, their behavior changes dramatically, and this is often accompanied with a change in physical characteristics.
Eta: the locust is a specific grasshopper species that has undergone metamorphosis , as described in Doc's link

Just based on my observations of the water level at bastrop back when the most recent flood hit travis (October '18?), Bastrop flooding would be severe at a minimum; there's a bit of storage in the floodplain between Austin and there, so the peak wouldn't be as bad (relatively speaking). There's significant storage in the floodplain between bastrop and wharton/bay city. Not sure how bad flooding would be down near the coast, but the river would certainly be flowing full in its main banksAlso I would think Bastrop and the other towns all the way to Matagorda would take a beating. -
The erosive velocity of the septic river emanating from within the tunnels would likely do itWhat about an entire high school football team that spent the evening at a Taco Bell? -
I had to correct my quoted post. Depending on the downstream foodways it could conceivably rise that high under a sunny day scenario. The only difference sunny vs pmp make in this case is how long the rate of water level drop.
You could argue that pmp would be more likely to lead to total dam failure compared to terrorist activity (ie, no dam vs a whole in the spillway), and that's a valid challenge (and thinking about it more, probably more correct). I'm assuming a complete uncontrolled release in my 'analysis' which is picking a little from pile a and a little from pile b; mix em together and its worth about a pile of shit. -
And it presumably differs depending on whether we're talking about the probable maximum flood or the sunny-day scenario. But since we're talking about a terrorist attack or something of that nature, we should probably stick with the sunny-day scenario.
Well had to rethink what I wrote here. I agree with this in the sense that the mode of failure would dictate severity of the event. However, I think the discharge due to complete dam failure would be an order of magnitude more than the upstream inflow.... but I may be way off on this

Man, I posted my last response before reading your follow up.
Note, I have not studied this in great detail, so a lot of what I'm saying is based on my judgment and general knowledge of the topography.
Depending on how fast lake travis drops after Mansfield fails, yes, it could conceivably reach that high. -
LLs post got me to thinking about what may happen if Mansfield did go. I imagine the flow regime goes subcritical to super critical through the busted dam, then a hydraulic jump downstream before the foodways narrows at the cliffs and then subcritical until about mopac, then supercritical again where the foodways spreads out. The subcritical portions will be flowing higher and slower (relatively) compared to the shallower and faster super critical sections. That said, probably isn't worth differentiating the flow profiles as either would be catastrophic

In general terms, assuming level pool routing, you aren't far off. However in this case, you need to look at a more energy dynamic model since the reach distance between Mansfield and Tom Miller is not great enough to attenuate the flood wave before hitting Tom Miller. The ensuing flood wave would likely be significantly higher than the top of the dam.... pretty much just cover it up and sweep it away. It's that extreme wave height that'll flood a much greater area.I would suspect that the inundation maps are pretty similar.
Downstream from Mansfield, the Colorado flows through a pretty significant gorge all the way to Tom Miller. If Mansfield were to fail, that water would flow at high speed through that gorge until it hit Tom Miller.
At that point, the flood would overtop Tom Miller as soon as it got above 519 feet msl (i.e., the elevation of the top of the dam). Overtopping Tom Miller Dam would cause it to fail within a short amount of time. Tom MIller's failure would quickly lower the level of the flooding of Lake Austin.
So basically, anything upstream of Tom Miller Dam that is below about 530 feet msl would probably be inundated in that type of scenario. But looking at a topographical map upstream shows that there's not just a whole lot below that elevation.
But hey--don't trust me. I'm not an engineer and I haven't done the H&H modeling.

Thanks for the response. Your first paragraph clears up one of my concerns and the second confirms my understanding of the general mechanics.
One follow up question, and then I'll pass the mic: how selective is the Fed when evaluating the loan, or how often do they say no or request a lower risk profile from the borrower? Curious as to whether that would be a canary in the coal mine type indicator, or if it's something that happens with regular occurrence. -
Thank you for the link. I'll surf around through this data later this evening.Ponzi scheme? How so?
Ponzi scheme may not be the best descriptor. My concern is this: Fed loans Institution A $x dollars on Monday, to be repaid on Tuesday. Institution A is able to repay on Tuesday, but then at the end of the Tuesday, turns out they need to borrow more money. This continues daily for a couple of months.
When Institution A repays their loan, where does that money come from? Why does Institution A need continual assistance to remain liquid? Also, It seems that there is not a healthy repo market currently, and without Fed support some of these institutions may be hurting.
I suppose my real question are these: is there a fatal flaw in the structure/ operation of the repo market in which the Fed participates? And what is the real risk to Everyday Joe if some unforeseen event happens? -

This isn't a bailout, its an overnight loan. You can even call it a bridge loan as it allows banks to maintain their capital requirements while funding their daily operational needs. Banks borrow money overnight and then return it in the morning.
It isn't a risky loan either as these are high quality securities, US treasuries mostly in exchange for money that again will be returned next day.
Is there any source that shows how much is being injected daily and the feds net balance?
When I first heard the story a couple of weeks ago, It assumed that the net deposit was $500B. But on further investigation of how that market operates, it sounds like it could conceivably be a situation where the fed makes $10B each day for 50 days, but each one is paid k back the next day.
Now, not knowing the rules, it's also conceivable (in my lay understanding and with the data, or lack thereof, provided) that the borrowers could potentially be running the market in a ponzi scheme like operation. -

Meant to say start/ stop locations; I imagine the actual routes vary.

I think they still use the same route as the original Cannonball races. 31st street in New York to Portofino Hotel in Redondo Beach

Yep. Seems like a pretty good group of caretakers at my son's daycare, and I'd like for him to continue going there (or maybe not have to go through the pain of finding a new place) and hope they can manage to come out the other side alright.
