No Dim, we decided others' health isn't valuable. When its our own, we'll sell our own mother into slavery for a faint hope.

How many electrons did you want to store ? One mole of Hydrogen, about 2 gm, has approx. 6*10^23 atoms. of H2 IOW about 1.2*10^24 electrons. All neatly stored, using no power. To release them just supply the ionization energy.

Don't misunderstand, I'm not necessarily picking on the Chinese, but any unhygienic form of animal farming and slaughter. These Oriental wet markets bring all the worst circumstances together. Different animals that are usually separated geographically, are kept in stressful/unsanitary conditions, in cages next to each other, and are then killed/skinned/cleaned in the same area, were bodily fluids of one specie may contaminate another. If this isn't a best case scenario for viral transmission, I don't know what is. I'm not saying this doesn't happen on pig farms, chicken farms, or in the water in India, and maybe we should be looking at the way pigs and chicken are farmed, as I'm sure most of the world's population is aware of not mixing drinking water with toilet water ( or at least, should be ). Another question which comes to mind... If you've had COVID-19, built up a supply of anti-bodies, and recovered so that you are now immune to re-infection, are these anti-bodies transferrable ? Would a blood transfusion give the receiver the anti-bodies developed by the donor ? and would these anti-bodies be effective ? IOW are anti-bodies tailored to the invading virus, or the host cells ? ( go easy on me, Last biology class I had was Gr.10 )

One factor which seems to be getting ignored during this outbreak, is the root cause. Possibly because investigating it has racist overtones, but I think it can be discussed in a civil manner. India is as overcrowded as China and probably even more insanitary in certain areas, yet no major diseases have originated there. China, on the other hand has given us SARS in 2004, and now COVID-19. Both are thought to have originated in Chinese 'wet markets", where exotic animals are caged in close proximity, under stress, and slaughtered on the spot for customers who believe their consumption provides health, sexual, and other benefits. Both virus are common to bats, and while SARS made the jump to civet cats, and then to humans, COVID-19 is thought to have jumped from bats to pangolins ( scaly anteaters ) and then to humans. Mutating with each jump. Turtles, snakes, cats, birds, bats, etc. in close proximity, and a great demand from wealthy Chinese for these exotic meats is the root cause ( what benefits does shark fin soup really bestow ? ). These markets are common in China, Thailand, Vietnam, etc., where poor farmers can make good money by raising exotic animals that were never meant to be in proximity. China did close down some of these markets after the SARS outbreak, but they've looked the other way, as wet markets made a comeback ( as in Wuhan ). Other diseases have also resulted from the overcrowded and unsanitary methods of raising pigs ( swine flu ) and chickens ( avian flu ). Is it time that the world demands the ending of these wet markets ( especially the exotic animals part ), and other unsanitary livestock activities ?

The ventilators are a 'treatment' for fluid in the lungs, or pneumonia, caused by the inflammation of the bronchial lining. They don't treat the infection, but rather, the symptoms, which are what actually kills you. The severity of the fluid build up in the lungs depends on a wide range of factors ( age, smoker, asthma, etc ), the only one of which is related to the COVID-19 virus itself, is whether the infection occurs in the upper respiratory tract ( milder symptoms ), or lower tract ( worse symptoms ).

I guess that's why our previous discussion regarding B Lazar ended up in the trash. I remember seeing him on TV in the 90s, making those outrageous claims. The only thing I've seen of him more recently is on the Joe Rogan Experience ( podcast ), and, for someone who was hired by the Government to reverse engineer a 'gravity' drive, he did not have a clue as to the workings of gravity or its effects. I nearly fell out of my chair when he said the 'old' theory of gravity involved propagation by gravitons, but it is actually a wave, evidenced by the 2016 BH merger detected by LIGO. ( gravitons are manifested by a quantum field theory of gravity, which we don't yet have, and he seems confused about gravitational waves ) He also employs certain 'tricks' in his interviews, like having an associate 'surprise' him with some 'evidence', which he claims not to have known about, in an attempt to be more believable. However, some people, even on this forum, seem to fall for his line ( along with hook and sinker ).

Why would people need currency exchange in a temple ? An airport, maybe. Just kidding; its been a while since elementary school, and compulsory religion classes.

I don't know if that's true. Symmetry considerations support least action. "A well known example is furnished by the theory of the pure (sourceless) electromagnetic field. One may infer its action from the requirements of gauge symmetry, time reversal symmetry and Lorentz invariance. From that action one infers the energy momentum tensor (by the well known recipes for the canonical or symmetric one). Then by requiring that the tensor’s divergence vanish (energy–momentum conservation) one ob-tains a set of equations which, for generic values of the Faraday tensor, imply that the latter’s divergence must vanish[2]. Thus the Gauss and Ampere laws emerge from energy–momentum conservation, itself a consequence of the symmetry of the action under spacetime translations. The magnetic Gauss and Faraday laws are automatic consequences of the use of the electromagnetic 4-potential as basic field variable. Thus, in the mentioned example, the symmetries plus energy–momentum conservation lead to the field equations without any appeal being made to the LAP." https://www.sciencedirect.com/science/article/pii/S0550321315000267

Not sure how we got to simulators/games; the OP was about using a computer to facilitate piloting a helicopter. A helicopter is inherently stable, its center of gravity is directly below its center of lift. A plane, on the other hand, can be unstable, to facilitate aggressive maneuvering. While a stable plane has its CcoL behind of the CoG so that the tailplane has to provide downward force to pitch, an unstable aircraft has the CoL ahead of the CoG making pitch departure that much easier, and increasing maneuverability. A pilot cannot cope with the constant control inputs to keep the plane flying level, so a computer is inserted in the electrical control system ( fly-by-wire ). These used to be triple redundant with manual ( control cables ) back-up, but nowdays make do without the manual back-up, and maybe to quadruple redundancy. The computer translates the force on the stick ( they don't move anymore ) into control laws, along with departure limits, and background trimming to keep the plane level. Since most 'modern' aircraft were designed in the 80s and 90s, the processors used in the F-22, B-2, F/A-18, F-16, Typhoon, Rafale and Gripen are all 386/486/early Pentium. I see no reason you couldn't have an electrically actuated ( fly-by-wire ) helicopter where a computer takes care of all background tasks and limits departure, allowing for a single stick control with a throttle, as on a video game. edit: sp mistake

A Commodore 64 has enough processing power to control a fly-by-wire system for a helicopter ( if one were built using fly-by-wire instead of control cables ). The only reason modern simulators need the latest/greatest processors is for the realistic graphics/gameplay. Most military computers ( where you usually find fly-by-wire systems ) are programmed in ADA, an outgrowth of Pascal and widely used by the Defense Department, so you wouldn't actually be able to use an MOStech 6510 processor. The central processor used in the F-22, with the most advanced fly-by-wire system, is only an Intel Pentium 90 ( 90 MHz ) from the early 1990s.

Books like the Bible, which are meant for moral guidance ( not historical account ) usually reflect the morals of the times they were written. The Old Testament part is much more violent than the New Testament, wherein the only time Jesus gets mad is when he upsets the money-lender's tables in the temple, and, he asks his Father to forgive his crucifiers. This reflects the change in moral values that had occurred. I would expect a 'Modern Testament' ( if one were written ) to have much different messages/guidance, especially in relation to the treatment of women, homosexuality, certain 'sins', treatment of the poor, etc.

If he thinks CharonY is bad, wait till he gets a load of Swansont, the 'evil liar' ( so I keep telling him )

I believe it was only about a week or two ago that 60 000 Italians, from the affected northern region, travelled to Switzerland daily for work. Now even the Swiss, who follow the rules religiously, are heavily infected, and thein infection/death numbers ( per capita ) are getting lose to Italy. The population of southern Italy consists mostly of old people, as the young move North where work is. Even my home town ( of 4000 people ) had its first case last Thursday. If people don't take this seriously and follow procedures, most of the population of these small towns will die off.

I don't think any zoologists feel the need to be secretive. We were driven by fear and greed ( don't know about malice ) 40 000 years ago when we co-existed with Neanderthals. We have travelled to the moon, and we're still driven by those same qualities. In a thousand ( or a couple ) when we may be able to travel to other stars, we'll still be driven by those same qualities. Advancement helps control instincts and emotions; it doesn't get rid of them. One question comes to mind... If co-workers ( ? ) remembered B Lazar, why didn't the interviewer ask them about him ? Maybe he was the janitor, or the cafeteria guy, or a financial controller, or the guard, or the ...

Exactly ! Why would I go all the way to Africa to play 'games' with crocodiles ?

So let me get this straight. A race of aliens travels at least 50 LY ( We've been transmitting EMR for 100 yrs, anyone closer than 50 LY could have signaled back ) and when they get here, they hide from us ? Maybe I'm not a super-intelligent alien, but that seems kind of pointless to me. Maybe he was the janitor.

Another custom is total disregard for rules. Lockdown ? What lockdown ? I'll do as I please.

B Lazar has been making these claims for over 20 yrs. I distinctly remember seeing him on TV shows dealing with UFOs in the 90s. Wouldn't the simpler explanation be that he has no academic records from MIT/Caltech, rather than the Government 'scrubbed' them ? And what makes us so special that they'd want to play 'cat and mouse' games with us ? You'd think they would explore the galaxy, not anally probe Americans from southern states.

The power generated by this heater is equivalent to V^2/R in a constant current situation. But you can also vary the current, keeping the voltage constant, in which case it is equivalent to I^2*R. IOW increasing the current while keeping voltage low, is your best bet to keep it safe with adequate insulation.

The white thermal compound is Aluminum Oxide in Silicone oil carrier. Aluminum Oxide has good thermal conductivity but poor electrical conductivity. As Studiot mentions, however, in paste or grease form, it is squishy and will allow metal to metal contact.

Judging by the empty toilet paper shelves ( and canned goods, dried pastas, etc. ) in the supermarket, I would say herd mentality, along with fear and panic, are much more contagious than COVID-19. I wonder if this opens the door to universal health care in the US, as this pandemic will likely have greater effect than 9/11 did.

Best strategy is stay at home if you can. And if you find yourself weakening, watch old movies like The Andromeda Strain, The Satan Bug, Contagion, 28 Days Later, Outbreak, 12 Monkeys, I Am Legend, or even Rise of the Planet of the Apes, to motivate you.

Not everyone who is infected is hospitalized. Most people who are infected experience mild symptoms and need to self-isolate. The ones who do get hospitalized are the elderly ( over 70 ) and those with pre-existing medical conditions which have compromised their immune systems. Not all 60 million people need to be cycled through the hospital system. The problem is, Italy has one of the oldest populations ( more people over 65 yrs ) compared to other countries in Europe. But other countries are starting to catch up to Italy. Switzerland and Spain are very close; but for some reason Germany is an outlier of the data set, with much lower infection numbers. edit: corrected Spain, not France

Removing glue residue... Yet another use for WD-40.

There's always 3% Hydrogen Peroxide, or a 5% Hypochlorite solution made from household bleach and water, Stringy. What purity IPA are you buying anyway ? Standard drug store stuff is only 50-75 % IPA. ( AKA rubbing alcohol )
