notbatman,

I am traveling to Antarctica next week. I will be there for several days. Is there any evidence supporting FE that you would like me to gather or are there any experiments that you would like me to run?


You could check if Lake Vostok is still 38 Fahrenheit or if global warming made it suitable for bikini girls.

Quote
Observations indicated that the Barrier edge had moved some 30 statute miles (50 km) south since Ross's time, which meant that the ship were already south of Ross's record.
Borchgrevink was determined to make a landing on the Barrier itself, and in the vicinity of Ross's inlet he found a spot where the ice sloped sufficiently to suggest that a landing was possible.
On 16 February he, Colbeck and Savio landed with dogs and a sledge, ascended to the Barrier surface, and then journeyed a few miles south to a point which they calculated as 7850′S, a new Farthest South record
Almost sailed to 80 south in "Ross sea".

Does anyone know what the urge was to pick up a rock 5 miles form base instead of just bend down and pick one up?

The other thing, weight is a major issue why were no wheels with spokes used?

The medal mesh getting pressed down to the inner frame is a power inefficient nightmare. It is even worse as driving with so little tire pressure to almost compress down to the rim. Each and every cross-section of the mesh chafes, what the hee hah?

The fierce fighting between the XRP gamble and Ripple investor continues.
The one or other XRP'ler bleeding heavy lying in some cold war trench wishing he never sight up to this battle.
For every winner there must be a loser, just a simple life lesson.
The good thing only 90 Billion XRP to come and the war be won. (added to supply is not same as sold, true sold numbers we know in some weeks)
As the year comes to another end, some numbers:
December 30, 2018 XRP supply was 40794121066, today 43319477613 a plus of 2,525,356,547 for 2019 or 2.52% of total supply.
Averaging about 7 million per day  2525356547 / 365 = 6,918,785
In past years the most notable is the manipulation at start of 2018 as price was high, supply slowed.
Once scaling is sorted and XRP cant be bought to its knees with large amount of data the battle will intensify again, maybe.


2020 will be the year most companies will have the own token, just like they have a website now.

I'm pretty sure that electronic cars are the future, i don't own one myself yet but i want to once the oil reserves dry out there will be the need for
another kind of fuel for cars and electric cars are a step in the right direction. I also think that a lot of people will still drive normal cars until the oil runs out because of the sound and the feeling that you get with a regular more specific fast car or a muscle car for example, but maybe we could solve the sound issue by installing a hifi surround sound system imitating a muscle cars noises  Smiley

You mean the past is the future,
1828 first model electric car.
1837 first batteries powered locomotive
1887 first electric taxis hit the streets of New York
Turn of last century more electric cars where on road as cars with internal combustion engine.
Electric vehicle held land speed record until around 1900
1975 the U.S. Postal Service purchased 350 delivery jeeps from AM General
What will happen with the mountain of toxic waste once batteries are past usefulness
The "oil running out" scam is now running for centuries



For someone a lot of time to waste and no life queening for hours is not an issue and start charging.

Many company's in the past have tried to print the own money, every single one has been shut down.
If one company can have it all will have the own currency, why not cost next to nothing to produce and sell for what ever price.

"...Would a medal engineering company not be a better choice to provide steel mesh tires as Goodyear, a Rubber Company?..."
IIRC tires have steel belts.
...

Steel belted radials were just coming to reality in the years of the various Apollo missions.


No, the 1970 model Lincoln Continental Mark III was the first American-made vehicle with radial tires as standard equipment.
The Citron 2CV came from factory with radial tires fitted in 1948 as standard.
A steel belted radial tire is nothing like a steel mesh tire where the mesh compresses to the inner-frame under load.
Quote
Four major components comprised the LRV tire's design: mesh,  tread,  inner-frame and  hub.


Is like equipping the billy cart with power steering (60lb/27kg)
Quote
The approach worked because each tire was only required to support about 60 pounds of weight (on the Moon, the equivalent of 360 pounds on Earth) and be used for a maximum of 75 miles.



Prior to the LRV the MET (Modularized Equipment Transporter) Apollo 14 did have inflated tires.
Quote
The MET was a two-wheeled vehicle with a tubular structure 86 inches long, 39 inches wide and 32 inches high when deployed ready to use on the lunar surface. The MET had a single handle for towing and has two legs to provide four-point stability at rest.

The MET was stowed during flight in the Modularized Equipment Storage Assembly (MESA) in the LM descent stage, and was used during both EVAs. Equipment was mounted on the MET for the geology traverse included the lunar hand tool carrier and the geology tools it carried, the closeup stereo camera, two 70 mm Hasselblad cameras, a 16 mm data acquisition camera, film magazines, a dispenser for sample bags, a trenching tool, work table, sample weigh bags and the Lunar Portable Magnetometer.

The MET tires were 4 inches wide and 16 inches in diameter, and were inflated with 1.5 psi nitrogen preflight. The tires were baked at 250 degrees F for 24 hours preflight to remove most of the antioxidants in the rubber. Operating limits for the MET tires are -70 deg. F to +250 deg. F.

Empty weight of the MET was 26 pounds, and the vehicle had a useful payload of about 140 pounds (Earth weight) including the lunar soil samples to be brought back to the LM from the geology traverse.

Estimated travel rate of a crewman towing the MET, as determined by tests with the 1/6-g centrifuge rig at MSC, was about 3.5 feet per second, with a one pound of pull required on level sand.

From Press Kit, Release No: 71-3K, Project: Apollo 14.


Judging by the footprints the cart is still at base and not attached to power source.

Why NASA provided it is unknown, whats interesting is the illustration of the Buggy unloading. It seems it was attached to the outside and then lowered like a Drawbridge.
The LRV sure has some bizarre design features like 4 wheel steering which is very handy in thigh cornering, but on the lunar surface?
Another is the added complexity to have electric power steering. Power steering is very handy on heavy vehicles but the LRV only weight 210 kg/ 463 pounds and additionally is only a sixth of gravity. On a single use battery using 4 motors just for steering 100 pound heavy vehicle?, odd.

It wasn't a Sunday trip to the mountains, there were many unknown unknowns. In the end many of those design constraints were moot, but what would you expect from the first trip to the Moon? It was mostly guesswork and the other part is that it was funded by the government, do you know what that means? When the Space Shuttle was designed there were also many other ridiculous constraints because the military wanted to be able go to space and steal a satellite and go back home in less than a day. It was never used but it impacted the Space Shuttle design.

People doubting going to the Moon in '69 should stop with the fake conspiracies and should put things into context. It wasn't that there were aliens, it wasn't that it was all fake. It was that the funding came from the military and you add government red tape bureaucracy and politicians bs and you get something ridiculously expensive and with some doubtful design decisions. It wasn't perfect, it was human but it worked alright.

And then funding was cut so we've had to wait more than 50 years till someone gets to do it in an economically sensible way.

Thats the whole point 4 wheel steering is expensive, complex and higher chance of failure as a straight rear axel. Budget is key word.
Power steering on a mission critical mission on something weighting 100 - 166 lb is strange. Much cheaper more relay-able options available.
Another strange engineering choice is the use of high rpm low torque motor driving low speed on uneven terrain.

6 Motors totaling almost 1KW (932.12 Watts)
Quote
Each wheel had its own electric drive, a DC series wound 0.25 hp motor capable of 10,000 rpm, attached to the wheel via an 80:1 harmonic drive, and a mechanical brake unit. Maneuvering capability was provided through the use of front and rear steering motors. Each series wound DC steering motor was capable of 0.1 hp

There was already some knowledge as LRV was used on Apollo 15,16,17
Apollo 11, Launched 16 July 1969, Landed on Moon 20 July 1969, Sea of Tranquility, Returned to Earth 24 July 1969

....Because most people know that it is impossible to land on the moon.

Six American manned craft landed on the moon, a total of twelve men.


and three electric vehicle waiting patiently for the next guy doings some wheel spins

Those ran on two 32aHr batteries each. It's rather amusing how small that battery pack would be today. So yeah, bring your battery, hook it up, and that moon buggy should go!

Not sure where you get the info from the 32 aph batteries, this NASA site says 121 Ah

You seem to confuse improvement with innovation.
The AC induction motor as used in pre model 3 is technology dating back to 1887 and was invented by Nikola Tesla
As it is extremely inefficient to take DC power source (battery) run it through a inverter to power AC motor, from model 3 onward the older tech DC motor is used.
