Teeth are all I believe that is not replaced, they are used as a locator for isotopes in the water in the region that you grew up in.

Try a hot air gun paint stripper! The key to achieving high temperatures is mass, you will need a large volume to keep a large temperature. Insulation will not work as you have a problem with the fire needing oxygen.

General Science / Re: co2 bomber extinguisher

Hi. I come up with extinguisher that can kill forest fires. I call it CO2 bomb.

Looks like American-football ball, but bigger. inside is lots of liquid CO2.
Drop one in the forest fire. Valves will open and release huge amount of liquid CO2, which will become gas.  8)

Fires need heat fuel and oxygen, you need to remove one to extinguish the fire. You cannot reliably remove the oxygen from a fire for a sustained period, nor the fuel in any reasonable scenario using fire suppressants etc, so you need to remove the heat. Extinguishing the fire may remove the heat from a small fire long enough to cool the fire but a large fire needs cooling down a great deal, this is why the fire brigade spend long periods dampening fires and raking through material piles.

Co2 from solid to gas I would bet has a far smaller  energy requirement than liquid water to gas.

Damn global warming.

It must be confusing living in your simplistic world. 
  If there is an unusual hot spell and an unusual cold spell in the world at the same time then you are probably just completely befuddled.
Where as you know the above is global warming, and can produce a reason in lightning speed that supports it as such given your genius as you testify too yourself!

Methane is now thought to contribute between 35 and 50 percent of global greenhouse gas effects, gas useage has been rising pretty much in line with this warming trend


* 202107_Percent_of_global_area_at_temperature_records_-_Global_warming_-_NOAA.svg.png (115.12 kB . 1365x1024 - viewed 2470 times)

The methane in the atmosphere is increacing every year, there is a natural sink of 550m tonnes but 570 emissions. Fossil fuel extraction contribute 33percent of "man-made" emissions or 100 percent of non biological cycle emissions, 100 million tonnes is vented by fossil fuel industries.  Methane however is short lived. If we reduce using methane gas usage we could reduce the amount in the atmosphere quite quickly.

Lot of pattern changes in the ambience of the environment, Right?

Perhaps Our drastic change in actions might somehow explain the " Weird " Climate.

Probably once Everything kicks back in full motion, say 2022 onwards, then maybe it would be Weather as Usual/Normal.

Record breaking fires last year, record breaking hurricanes last year, this year not so, but there is unheard of cold in Brazil and Australia, heat pushing further toward the pole in summer, coldfurther toward the equator winter. The weather is literally shifting.

I realise summer and winter as I speak are both at the same time.

the people were known to have changed their minds.
To state that 33,000,000 voters have changed their minds is an assertion of psychic power beyond the wildest imaginings of a raving lunatic.

Fortunately we have elections and referenda to eliminate the need for psychics.
The pollsters have been so on the money recently.

The conservatives have trouble swallowing Islam ,  Labour Judaism.
Too simplistic.

All politicians want is votes.

Time was (1930 - 1970) when the Left opposed fascism, the Right supported it, and the Muslim vote was too small to matter, so Labour was distinctly pro-Jewish and the feeling was mutual. Now there are ten times more Muslims than Jews in the UK, and some (say 10%) are distinctly anti-Jewish, so it behoves one party to secure that vote, and the other party to secure the equal number of Jewish votes by appearing anti-Muslim. Since most British Muslims have brown skin, it is logical for the party with a pro-fascist history to take the anti-Muslim line.
While during election time a politician will do and say pretty much anything to gain a vote, what I mean is the actual ethos of said religions is inherant my one way or the other. The Nazi belief in the racial superiority of the German peoples was suddenly found to be on par with the Japanese during Ww2 when necessity required it.

 Islam is very focused on communal operation, ie Afghanistan new beard and Burka trend for everyone and the importance placed on community. Judaism seems far more individual based, personal achievement.

Truthfully both Islam and judaism seem pretty right wing, but so does Christianity and so did Stalin

Communism is power through consensus, fascism is power through belief.

Result: I wouldn't vote Conservative because Rory Stewart (the only hint of competence on the front bench) was not elected leader, I couldn't vote Labour because some antisemitic prevaricator had been elected leader, and there was no point in voting for any other candidate in this sharply polarised constituency.
The anti semitic thing was because of brexit, of which corbyn was an ardent supporter since about 1980, I don't think he really wanted to be PM from the point of the leadership contest, all the way through brexit having to unite a clearly polarized party and up to the election, if he would have opened his mouth once he would be in downing Street.

The left is anti Jewish culture, the right anti Muslim, it is inescapable, it is like trying tell a physicist he should really look into how cows work.  The conservatives have trouble swallowing Islam ,  Labour Judaism.

Technology / Re: Ethanol fuel is the way to go
« on: 04/10/2021 23:03:48 »
No, for the same reason that solar is a non starter, because the land is too valuable to use producing fuel. If we could grow our fuel we could make methanol or wood alcohol, but grain and the straw that comes with it are too valuable. As an example, you can make fuel from animal slurry, but farmers value it too highly to sell for the price people will pay.

Because momentum is related to duration where as energy is just a total regardless of variables.
How should we interpret this statement? Is total volume becomes energy? Or total intensity?
Energy stored in a battery is often expressed in kWh. It means that energy is also related to duration.
Joules is also expressed as time dependant. But it is a total. Momentum is a quality.

All more or less along the same lines:

Wisdom is knowing what you don't know   -- Based on a Socrates quote, but not how he put it.

“Intelligence is knowing the right answer. Wisdom is knowing when to say it.”  ― Tim Fargo

"To know how to use knowledge is to have wisdom" -- Spurgeon

« on: 28/09/2021 18:09:02 »
Because momentum is related to duration where as energy is just a total regardless of variables.

In the same time for double the velocity the energy needed to counter it is quadrupled due the body having twice the speed and covering twice the distance. To counter the faster body with the same rate of deceleration , the faster body will have covered 4 times the  distance, so it takes 4 times the opposing force or energy.

If momentum is the effect a body will have on another in a set distance, the faster body has half  the time to exert the mass, but conversely for time, it has double the distance to exert its momentum through, or in other word there is double the opportunity for mass to act due to the doubled distance, the mass dwells for double the distance.

 Doubling the mass for the same energy increaces the momentum.
