i was a research person but i know offshore O&G production facilities are manpower intensive. The video you linked seemed to show that offshore turbines were continuously staffed and showed a lot of support activities that appeared to be do-able onshore vs onboard. Thus the wasted money. If windmills only require periodic maintenance, then there would be no need for a ship of the shown size, staffing, and sophistication.
more specifically, the video shows an apparent need for a lot of manned infrastructure support. If humans have to actually man each windmill and do shipboard support, then way more expensive than oil and gas.
wasted money
that was supposed to be stacks of dollars with wings. Phone app problem
????????
cant think of a more cutting insult than to compare Tesla to Subaru (and I thought once Subaru got past their death trap stage of development, they were tough, affordable cars)
in one of the preceding posts to that link there’s a graphic of batteries. The label and the graphic should be telling wrt to the cost and purported energy efficiency of batteries vs ICE vehicles
India & China are 2 very different problems wrt Tesla. As for my expectations wrt India: I’ll believe Tesla will have significant sales when Indians stop relying on US for grad school and tech jobs.
I don’t think Tesla is gonna make any money in a country where even affluent people have to take a taxi to an Internet cafe
both are terribly inefficient mechanisms but the pumping water option requires reservoirs. If solar in CA, the power generation part tends to tend to be hot and arid places. The reservoirs would be close by. The vertically lower reservoirs would become like the Salton Sea - saline and chucky full of agricultural runoff so it wouldn’t be a simple matter of pumping freshwater uphill during the day and letting it run down gravitational gradient thru generators at night. Environmental, & consequently engineering, problems will arise. Wouldn’t be as big a problem for places with wind like east of SF but then the land is probably more expensive and there would be different flavors of environmental concerns
I think VZ is doing the conning. I’ve heard the ‘long game’ argument before wrt to VZ. It wasn’t money that the vendors were left holding as the only thing to show.
Calling it risk is being benevolent. Throwing money at Venezuela is either an act of charity or insanity (ie expecting a different result)
I wouldnt be surprised if more people crossed international boundaries in 1918 - WW1, repatriation of soldiers, support personnel, occupation of parts of Russia, colonial transfers ...
safety is not the problem w Mtn Pass unless you’re counting the regulatory costs as ‘safety’
budding 330k sq ft glass office tower. There’s a architect’s picture of the planned building viewable on google street view
they’ve only ‘captured’ these resources in terms of low cost labor and the absence of any environmental protection. Similar resources exist in many places outside of China or Chinese operational control.
ty. How well does it work in snow/rain?
Pu239 and U235 arent particularly volatile but they can still make a big boom.
Lithium battery packs occupy a lot of volume and area within an EV and consequently terminal damage can be incurred from below or any side, e.g. collision from front, back or side; bottoming out on a speed bump; running over a curb; or damage from road junk can compromise a battery casing. From that point, simply running thru a puddle can cause ignition but it wont necessarily happen immediately - thus the cases where EVs have ignited while parked. With a Li fire, spraying water on the fire makes it worse and a CO2 extinguisher wont necessarily have any effect. All the necessary fuel components for the fire are within the battery. An Li battery pack could be 10 m underwater and still burn. That wont happen with an ICE vehicle.
I dont think an EV is any worse or better than an ICE vehicle wrt to ignition hazards for normal road driving but there is a different set of hazards to which most people are clueless. Little driving faux pas that some people might blow off for an ICE vehicle could be terminal to an EV. I dont think Jeep will ever make a serious off-road EV.
cuz it's texas and they pride themselves on such things. Probably wouldnt be a problem if coal plants were still practical. Not pushing coal, just pointing out that a large part of their electrical power production was coal fueled until ~10 yrs ago and things have been in a bit of flux since. Change doesnt alway beget rose petals and rainbows.
The same system that knocked power out there dumped sleet on me for >14 straight hours with howling wind. I was amazed that we didnt lose power. I suspect the ice and added weight on tree limbs and power lines and shorting were responsible for most of the power outages.
I also remember power outages in NJ and NY that happened in perfectly clear weather that affected many more people so i dont think this is a case where Texas' way of handling their electrical grid deserves condemnation.
Your statement is true but are gas hydrates a common problem in distribution systems? I would’ve thought that mid- and downstream folks would dehydrate the crap out of the gas they distribute.
There have been some very dramatic and expensive failures due to corrosion in gas lines, eg the family that was camping in TX and were blown up along w a nearby bridge.
because of cold weather? You don’t think that it might have something to do w low oil prices and the Biden administration? NM was the 3rd largest producer in country. More than 50% from federal leases. If they stay in top 5, it will only be because US product, in general, plummets.
It’s not like it hasn’t ever been cold in NM, CO, MT, & ND
speaking of Cuba: if all the happy talk of cheap EVs and green energy were true, why are countries with lots of sun and wind still running nearly 100% ICE vehicles w nary a Tesla dealership to be found. It isn’t just dysfunctional quasi-communist countries.
that’s 1 reason. It’s mostly a replacement cost problem: ICE vehicles and liquid transport infrastructure already exist. If you want a 1955 Chevy that runs, go to Cuba
I forgot the 2nd part of your question. Yes, margins way higher on liquids. But if EVs were to become predominant, then NG prices and margins would grow accordingly.
yes and no. service companies have been beaten like an old rug for 5 yrs so they’re skeletal already.
secondly, a large fraction of the world will continue to burn liquids. That assumes all the happy talk about EVs comes to be in Western Europe and NAM. I won’t be around to collect on bets of what happens/doesn’t happen in 30-50 yrs but if there was a chance, I’d wager a lot of money that EVs will not comprise 50% of US vehicles in 2050.
oilfield services companies probably believe as I do that there is no way that windmills & PVs will be able to supplant the NG fueled electrical needs of the country - much less chemicals. EVs, fracking bans & other aspects of the Green New Deal will drive up NG costs and service companies will b happy.
I know that SLB is also putting more focus on stuff like geothermal and Li brine recovery.
and since mining will boom in this ‘Green’ future, I’m sure the oilfield service companies will shift/restart those parts of their services.
I’ll find it humorous when folks find out that geothermal wells are also fracked. But given the hypocrisy and illiteracy of the world, I’m sure convenient exceptions will be made.
production in UT and WY << NM but isn’t a lot of resource in UT & WY under fed land?
completely lacking in credibility
am in agreement w your original post. Was just throwing on a little flavoring/advertising for PubPeer which is a resource that science journalists, scientists, and tax-payers, & bio-investors should be aware of.
If you follow PubPeer, even peer-review is far from unfallable
I think the protein was isolated from a thermophyllic organism living in a Yellowstone thermal pool. There was a valuable patent involved that excluded the fed govt and that’s why scientific sampling from national parks (or at least Yellowstone) now requires a mountain of paperwork
They overpaid for lots of stuff. Emblematic: I was eavesdropping on a conversation betw a XTO field guy & tax person couple yrs ago. His income pre-XTO acquisition was $95k. After $160k. Didn’t sound like he had more than high school education and I guarantee that people doing the same work in same place but for small independents were making << $100k
Nashville has become a very popular business and entertainment location over past few years. Unfortunately, the tax pathways, exacerbated by Covid, haven’t enabled transportation infrastructure to keep pace so traffic won’t be any better than CA. There’s also no light rail/subway system.
and no income tax on wages
several years ago Tesla made an offer to buyout Simbol Materials for ~$325M. SM had a process for removing Li from geothermal bribes. The deal fell thru. I am acquainted w the guy who was the technical wizard behind SM. Smart guy. Was royally screwed and I suspect there was some shadyness in the controlling partners who ousted the technical founder.
Li is too small to fit nicely into structures of most rock forming minerals which is why it’s found in late crystallizing rocks such as pegmatites (~rocks that form from all the leftover crap from fractionally crystallizing magmas - N Carolina & Canada), evaporites in basins lacking external drainages and significant rainfall (Andes), and absorbed on clays exposed to magmatic hydrothermal systems (the aqueous phase exsolved from the crystallizing magma carries Li away with it which interacts with overlying groundwater & sediments - Nevada)
Li doesn’t behave like Na so that part of article is BS. Both are alkali metals but the relevant geologic & battery-related properties are vastly different. The important part wrt to separation is to 1st remove all the other crap into solids and collecting the Li salts at the end just like Mother Nature.
absolutely nuts.
the freezing point depression of any aqueous solution i'd consider to be reasonable for injection will be >> -70 degC so even if the shipped vaccine contained 'free' H2O the mixture would be solid. Solids can still hydrolyze thru vapor phase but at those temperatures the amount of H2O would be so small that i cant imagine that it would be significant. Solid-solid hydrolysis reaction rates must be geologic at those temps.
Dewophile mentioned that jbog said the shipped formulation would be freeze-dried so the above is probably moot.
Around surface temps reaction rates tend to ~double with each 10 degC increase. I'm not sure if that is still true near -70 degC. If it is and the vaccine stability is simply temperature dependent, then something in the vaccine has some very fragile bonds and thus my question. If the vaccine is so fragile that it's viability is only days at -56 degC, then i'm amazed it lasts more than minutes once it's dispersed in a liquid for injection.
Patching the various responses together, it sounds like the shipped vials contain only solid (not surprising at << -40 C). I have my doubts that -40 vs -70 degC would make much difference for hydrolysis. H2O vapor pressure would be minuscule in either case. Based on the NYT article linked by Biowatch, sounds more like there is a oxidation/light sensitivity since they refer to freezer doors only being opened 2x day. If that’s the case seems like hooking up an Ar purge system to non -80deg freezers might be simple, cheap way of extending distribution/availability.
what makes the vaccine so fragile that it requires < -56 degC (dry ice)? I’m assuming it’s stored as a solid that is dissolved or dispersed in solution for administration @ ~20 degC. Also wondering how long it’s stable in that solution.
are you saying that NG or wind/solar doesnt work on levelized basis? In anycase, my take on LCOE numbers is that they tend to be as reliable as NEA forward oil price and consumption numbers. If a Biden/Harris administration does eventually succeed in pushing 10000s of EV charging stations, a substantial power contribution will need to come from NG.
wrt oil, we agree that oil prices will continue to be low but Venezuela continues to surprise me in just how long they can continue on their journey into the abyss. I would take contributions from the PRC as a negative, i.e. they wont advance VZ functionality since their competency and integrity is no better than those they are endeavoring to manipulate. In the end the PRC Central Committee will realize that their expenditures have been no better spent than the western enterprises that preceded them. I agree that Russia has no incentive to help.
