A foot is about the size of an adult foot, it makes sense.
Sure, that is why my GFs foot is 26cm long and mine is 40cm ... and the actual length of a imperial foot is only 33cm

Time btw is not "imperial" you have a strange idea what imperial is about.

Metric has its place, but using it everywhere makes no sense.
True. But the examples you gave make no sense either. BTW, if laymen say "metric" we pros usually call it SI. And the "second" is an SI unit :D

That is nonsense.
If you have a screw with a 1 inch head you use a 1 inch tool to manage it.
No one is going to ask you to call that screw a 26.xx mm screw, now will the tool be renamed.

Metric only means that you in future use a 12mm or 24mm screw, and the same for a tool fitting those screws.

Or do you really think any german craftsman is juggling with mm and inches back and forth if he has to handle a screw with 1"3 (do you write that so? one 3/16 inch ) by translating that into mm and then looking for a tool of that size? Rofl, the tools are named/numbered like the items they are used for ... it is still an 1"3 arc spanner and not a 30.1234 mm tool (sorry I made the numbers up, so no need to pull out a pocket calculator and correct them)

In an irish pub in germany or in any pub in france you also order a pint of beer.
And no one cares if it is a "true" pint or an approximately pint, as long as the size of a pint and the price is mentioned on the menu/card.

All your examples make no sense.

So 100 yards is more or less, how much exactly of 100 meters?

And you really believe that germans don't use cups and spoons i cooking books, how retarded are you?

Facepalm regarding your temperature rant ... Fahrenheit is determined by two completely unrelated temperatures: 0, the minimum you get with salted ice water ... WATER, oki, you get it? And 100 the "average" temperature of a human body.

Sorry, if it is 40degrees Celsius outside, we all know it is pretty hot, no one is comparing this with his own body temperature.

Units and especially the "normal" span of numbers in those units are just a matter of what you have grown up.

Living a year in a country with different units and you simply adopt them as you did the ones you grew up with.

Lol ...
Mars once had plate tectonics ...
From a mining perspective there is nothing Mars has not.
There is no oil or coal or nitrates.
IF Mars was once a planet full of live, as most modern scientists believe, then Mars is full with coal and oil.
However I wonder what you want to do with them on Mars. After you have sent ships to Mars, that need solar panels or nuclear reactors to reach it, why would you not reuse those on the plant, or build more.

There are people who believe mars can be terraformed with our days technology in less than 100 years.
www.marssociety.org
Or read the red/blue/green Mars triology. Yes the later is "just" SF ... but also basically only using our days tech.

People don't want to be holed up in geodesic dome glass domes and living underground like insects.
I know plenty of people that either never have left their home city, or when they did just visited another big city (like Paris or London).
For them it would be no difference if the whole city was under a dome.

I have read the first link you gave, not the second.

And I simply did not see any link, headline or what ever leading to a description how they found their data.

You pointed out, after a few more posts: there is one.

Sorry, what is so hard in understanding that people easy oversee such links? Why are you so damn hostile? Never learned about a civilized way to do a discussion?

I linked to these. You didn't read them.
You are wrong, I read the first one ... not finding any substance in it, I did not bother to read the second one.

And, to be honest, after you claimed "both" would nevertheless disclose their way how they gather the data, I did not check that so far ... so: no idea if they do. First time I read the first link, I saw _nothing_ about their data collection method.

But thanks for wasting my time with you ...

I don't think that there is a standard definition :D

Many things come together, e.g. education, industry, healthcare, not only "living from 1$" per day.

And actually, if you would be a tourist in the right areas in India you also would live from one dollar a day, or lets say you try hard to spend money, you hardly can spend 10$ ... except you want to live in a expensive tourist hotel :D

Comment Re:net metering != solar and 10% needs new physics (Score 1) 488

The world lithium "supply" is not a problem at all, I guess it is 3rd or 4th most abundant element on earth.
The problem is "production".

Batteries are overrated anyway. They are only helpful for people who want to be offgrid as much as possible. Unless we can produce renewable energy close to our peak demand, there is no point in grid wide storage.

The difference between peak and base is something like 120%, or other way around: base is 40% of peak load, depending on country it varies. So assuming you can at least produce 50% of your peak energy (10% more than the 40% base load), then you can store those "10%" and use it during peak time (works with wind). Solar works opposite as you can only produce power during peak time (or around peak time) ... grid wide it makes no sense to store anything from that. You rather simply consume it while it is produced. For a home owner or a sailor that is different. Those can schedule their appliances in a way that they always have a slight overproduction to store for the night etc.

In germany I believe the "wave" of home installations is over. Well, or we are approaching a second wave perhaps. Current installations usually have no storage. Future plans only want to subside solar plants that either don't point due south (to change the time window when they produce their peak) and/or installations that focus on consumption by the owner (with or without storage).

However you are right regarding Lithium, it is "only" an Alkali metal, in german the "rare earth" group is called "earth alkali" ... somehow my mind shifted Lithium into the other group :D
