“The Bitcoin community will be a very good thing for Texas & a very good thing for America.” -Senator Cruz @tedcruz

PoW is the best battery to store energy ever created. Wind, solar, other renewable sources of energy have largely failed due to insufficient batteries. 90% of "environmentalists" will reject this statement out if hand because of the source. He's right though.

there is actually a company selling space heaters that are actually bitcoin miners, using the chip as the heat source. Supposedly they can make you like 500$ a year if your electricity is cheap enough.

Chinese warships reportedly sailed near Alaska in what could be a clear effort to challenge U.S. Navy Freedom of Navigation exercises in the South China Sea.

Where are the Australian Prosecutors???

Bitcoin Lightning Network Layer 2 adoption is going "vertical"

Lightning is not a company; it's a protocol. If Bitcoin is like TCP, then Lightning is like HTTP.

"The main downsides/negatives to the LFTR are technology, politics, corrosion and the general public being scared of nuclear radiation.

Liquid Fluoride Thorium Reactors were created 50 years ago by an American chap named Alvin Weinberg, but the American Government realised you can't weaponise the by-products and so they weren't interested. Another point, yes it WAS corrosive, but these tests of this reactor were 50 years ago, our technology has definitely improved since then so a leap to create this reactor shouldn't be too hard. And nuclear fear is extremely common in the average person, rather irrational though it may be.

More people have died from fossil fuels and even hydroelectric power than nuclear power.

No, it would not collapse the economy (yes, people actually ask this question)... just like the use of uranium reactors didn't... neither did coal... This is because you wouldn't have an instant transition from coal... oil... everything else to thorium. We could not do that. Simply due to the engineering. Give it 50 years we might be using thorium instead of coal/oil (too late in terms of global warming, but that's another debate completely), but we certainly won't destroy the earth's economy. Duh.

And yes he said we'd never run out. Not strictly true... bloody sceptics ... LFTRs can harness 3.5 million Kwh per Kg of thorium! 70 times greater than uranium, 10,000 greater than oil... and there is over 2.6 million tonnes of it on earth... Anyone with a calculator, or a brain, will understand that is a lot of energy!!

Any more questions I will try and answer.

Thanks for watching. And please, please share this video with as many people as you can. The more that know about this, the greater chance of change."

I wonder if people outside of El Salvador in Mexico or Nicaragua would also benefit from downloading and using the Chivo wallet?

Congrats to the Salvadorans... they deserve a break

Collecting Information

Eratosthenes was a librarian, poet, mathematician, and astronomer.  He was born in a Greek colony called Cyrene—located in modern day Libya—in 276 BC.  When he was 40 years old, he became the chief librarian of the Library of Alexandria, an enormous repository of information from a myriad of locations and intellects.  He continued collecting information throughout his lifetime and eventually contributed some findings of his own.

Developing Latitude and Longitude

Eratosthenes is credited with inventing the field of geography and developed the first system of latitude and longitude for plotting precise locations on Earth. In his system it was possible to estimate the distance from any known points on Earth at the time. He also calculated the angle of Earth’s tilt and documented a catalog of 675 stars. 

Sieve of Erathosthenes

His “sieve,” known today in math classrooms as the Sieve of Eratosthenes is a method to quickly and efficiently find prime numbers.  In the sieve, a list of consecutive integers is generated starting with two and ending with any number (n). After two, every second number of the list is crossed out (even numbers). Since the next number is three, every third number is crossed out in the next step. Four is crossed out, but five is next, so every fifth number is crossed out. As the pattern continues, composite (non-prime) numbers are crossed out and prime numbers such as 5, 7, 9, 11, 13, 17, and onward are left behind. 

Circumference of the Earth

Eratosthenes’ most important contribution, however, may have been his calculation of Earth’s circumference using geometry and trigonometry.  Eratosthenes noticed that at noon on the summer solstice in an Egyptian well, the sun’s rays shone directly into the well and lit up the water—meaning that at that day and time, the sun was right above the well.  He then put up a tall pole in Alexandria that cast a shadow on the summer solstice, meaning that the sun was positioned slightly south from the pole.  After measuring the distance between the well and the pole and taking into account the Earth’s spherical nature, Eratosthenes measured the angle of the sun’s rays on the day of the solstice and related that in a proportion to the circumference of the Earth.  His calculation, while not totally airtight, yielded a high degree of accuracy. The same calculations performed today, with accurate data, result in the circumference of the Earth measuring only 66 kilometers off from its actual, accepted circumference. 

Eratosthenes died at the age of 82.  Although most of his original writings have been lost to history, we do have evidence of his mathematical work and astronomical findings which are highly relevant in both fields today.

And for a refresher course on Diodes in general .. this video seems very nicely animated:

Then I found this video that really gets down to the inner mechanics of a Light Emitting Diode.

Thought I would share.....

I still don't see the "filament" level process in the video above.... it just says .."two semiconductors" are placed close to each other...
