Today's question: Could the hyperloop really kill you?

The hyperloop seems to have picked up some speed lately, so it's important to consider how safe it would be.

A YouTuber by the name of Thunderfoot has made 7 videos explaining why the hyperloop is a bad idea.

I'm glad he's doing this because we should always have a healthy amount of skepticism when it comes to new technology.

But...there are some problems with his arguments.

Don't get me wrong.

Thunderfoot brings up a lot of good concerns, but every one of these problems has a solution.

Let's start with his first video, titled "How the Hyperloop can kill you!"

So I'm making my next Patreon-supported video, which is going to be busting the Hyperloop,

a project that might be better described as all the problems of space travel,

while traveling in a gun barrel at nearly the speed of sound.

First, I want to point out that the hardest part about space travel is getting the rocket to space.

Astronauts are strapped into what is essentially a bomb, that consists of 90% rocket fuel,

and somehow the other 10% has to maintain a controlled explosion to get the thing into space.

This is a really difficult task, but the beauty of tube travel is that you aren't strapped into a bomb

because there's no fuel to cause an explosion.

But my MAIN concern with Thunderfoot's video was his experiment.

Ok, so there's a little metal ball in my mini hyperloop.

Simulating vacuum failure.

Luckily, this is not what would happen in a real Hyperloop breach.

First of all, Thunderfoot's steel ball was about the same size as the inside of the glass tube.

That means that not much air could escape around the edges of the ball.

In a real hyperloop, pods would probably have much more space around them to let air through.

Second, let's think about what would happen if we made this ball 300 times bigger in diameter.

The mass of the ball scales with the cube of diameter, so it becomes 27,000,000 times heavier.

But the force on the ball, which is proportional to its surface area, only scales with the square of diameter,

so it increases by a factor of only 90,000.

Since acceleration is equal to force divided by mass,

the larger ball would experience 300 times less acceleration than what you saw in Thunderfoot's video.

Now, the math I'm doing is only a rough estimate,

but it should give you an idea of how different this experiment is from a real hyperloop.

Finally, I want to point out that this experiment did not consider any countermeasures.

In a real hyperloop, pods could control their deceleration by using a propulsion system,

deploying emergency brakes, and readmitting air into the system.

Now before you go, don't forget to leave a comment letting me know what you'd like to see in future videos.

Thanks for watching, and I hope to see you next time on Tube Travel.

Korea suffers billions in losses due to China's retaliation against THAAD deployment - Duration: 2:02.

South Korean retail giant Lotte Mart has decided to call it quits and pull out of China.

It has been forced to shut its stores there due to an unofficial boycott by China in protest

against Seoul's deployment of THAAD.

Korea's tourism industry is also reeling from a sharp drop in Chinese tourists to the country.

Kim Ji-yeon reports.

After racking up hundreds of millions of dollars in losses, Korean retail giant Lotte Group

is selling its hypermarket chain in China.

The decision follows the more than six-month-long closure of about 80 percent of Lotte Mart

stores in the country.

Sales came to a halt as Chinese authorities imposed stricter safety and sanitary inspections

on the stores, which was then followed by a nationwide boycott by consumers earlier

this year.

All this was in retaliation to Lotte's agreement with the South Korean government to offer

land to accommodate the THAAD missile defense system.

(KOREAN- ) "Nothing has been fixed yet, but Lotte Mart

may sell off everything it has in China or a significant chunk of it."

And it's not just Lotte Mart's fortunes that are spiraling down.

A report released by the Hyundai Research Institute on Friday... shows damages estimated

at more than 72-billion U.S. dollars annually... and up to 400-thousand job losses in the Korean

tourism industry.... as the number of Chinese tourists during the March to July period dropped

by 40-percent compared to the same period last year.

The report estimates that more than 3-point-3-million prospective Chinese tourists have canceled

plans to visit Korea during the past five months.

That means the usual spending by Chinese tourists in Korea, which amounted to an average of

nearly 2-thousand dollars per person last year... has disappeared into thin air.

Last year alone, Korea received 17-point-2-million Chinese tourists, some 46-percent of all foreign

tourists visiting Korea.

Africa | Church News Special Report - Duration: 22:01.

Three new houses of worship.

Thousands aided through a series of Aid For Humanity events.

In this special report of Church News,

join us as we look back in the historic events

that took place in the continent of Africa.

In the fast growth of the Church Of Christ in the African continent,

the pastoral visitation of Brother Eduardo V. Manalo has a big role

in the Local Congregation of King William's Town last August 30, 2014.

Multitudes of people attended the worship service, evangelical mission,

officiated by Brother Eduardo V. Manalo.

The Executive Minister saw the joy of those who attended

and their yearning to know the teachings that we believe.

After two years,

Brother Eduardo V. Manalo returned

to personally officiate a series of dedication of new houses of worship to God in Africa.

The Local Congregation of Johannesburg was first dedicated,

followed by the Local Congregation of Cape Town, both in South Africa.

After a year, another series of big activities were witnessed in this part of Africa.

From Johannesburg, capital city of South Africa, it is almost 400 kilometers going to Thaba Nchu.

This place is an area in the province of Free State.

It was February of this year, when the construction of the house of worship began.

After only 6 months of construction, the house of worship of Thaba Nchu was finished.

This house of worship can accommodate 180 worshipers in each gathering.

July 30, 2017.

The new house of worship was dedicated to God.

Led by the ministers and ministerial workers,

the Church members in this place offered praises to the Lord God.

By the instruction of the Executive Minister of the Church Of Christ, Brother Eduardo V. Manalo,

the first worship service in the new worship building of the local congregation of Thaba Nchu

was officiated by Brother Matt Pareja, minister of the gospel.

For members of the Church Of Christ,

the successes they witnessed gave them renewed inspiration in their services to the Lord God

especially for the pioneer members in this place like Sister Monica.

Just for this moment, many of the residents already showed their interest

in examining the Church Of Christ.

From the new house of worship in Thaba Nchu in Free State, South Africa,

we once again traveled to another project that was just finished.

This time, we need to cross countries to Semongkong, in the country of Lesotho.

From Maseru, the capital of Lesotho, we traveled for another two hours.

It was only last year, 2016, when the teachings of the Church Of Christ reached this place.

One of the ministers assigned here is Brother Andrey Silva.

The life of people here is really simple, they are self-sustaining for the food they consume,

they have a farm, they have their own livestock.

When we conducted evangelical missions, when we conducted our Bible studies,

they just sat down on the grass.

For the immediate propagation of the faith, they were assisted by translators.

Because of the intensive work of propagation of faith in this place,

led by the ministers, ministerial workers together with their respective translators,

there was a rapid increase of membership in the Church of Christ.

At present, many of the residents in this village are now members of the Church Of Christ.

That is also one of the primary reasons why they were given a house of worship.

At present, the 300-seater house of worship is the only landmark in Ha Fochane village .

On August 2, before the worship service started in this place,

led by the village chieftain, they showed their acceptance of the Church Of Christ through a parade.

Afterwards they attended the worship service together with many people who are examining the Church,

new members, and Church members from nearby places.

The dedication to the Lord God of the house of worship

was led by Brother Glicerio Santos Jr., minister of the Gospel.

In order to understand the teachings of the Lord God,

the translator for the English language was Brother Rommel Sanvictores

and for the Sotho language was Brother Moiloa Monatisa.

We thank God for using the Church Administration as instrument

because the worship service was brought closer to the people here in Ha Fochane village.

After the first gathering in the new house of worship in Ha Fochane,

they conducted the activity "Aid To Humanity."

After the Aid To Humanity in this community,

we proceeded to Maseru where a multitude of poor residents were waiting for us.

Countless "kea leboha" or "thank you"

this can be heard from thousands of residents who received aid.

This is the second time that the Church Of Christ held an Aid To Humanity here at the Setsoto Stadium.

According also to him, this outreach program is very timely

because of the extreme poverty experienced by the people of Maseru.

In the Aid To Humanity held for the people of Maseru,

the first ones to be given aid are the residents with disabilities.

The people went home happy

not only because they brought home food parcels

but because of the inspiration brought by the love and care for them by the members of the Church Of Christ.

Brother Eduardo Manalo really loves the Africans

because he sees the poverty of Africa;

he sees that Africans are truly kind

and religious people.

The Church Of Christ is propagating the words of God

for them to know about the true God.

Second, we give out food, and livelihood opportunities

because that is the commandment of our Lord God that we love our fellowmen.

After the series of activities in the country of Lesotho,

we traveled back to South Africa.

A day before the dedication to God of the house of worship of the Local Congregation of Ladybrand,

the brethren continued in the intensive propagation of God's words.

Our companions in the distribution of pamphlets, God's Message magazines, and invitations

are those in the process of joining the Church Of Christ.

Although they are not yet full-fledged members of the Church Of Christ,

they are already very excited to join the Church activities

like what we are doing now, the propagation of God's words.

The next day, the brethren prepared early to attend the first worship service

in the newest edifice here in Ladybrand.

This can accomodate 800 worshipers each gathering.

The dedication to God of the house of worship in the Local Congregation of Ladybrand

was officiated by the Executive Minister of the Church Of Christ, Brother Eduardo V. Manalo.

Brother Roger Rafols has been in Africa for already 40 years.

He is one of the pioneer members who first reached this continent.

He is overjoyed for the successive victories he witnessed.

I am truly grateful to God that I reached this day.

I am already 77 years old.

I saw how the Church spread,

and the construction of many houses of worship here.

My heart brims with thankfulness to God for the blessings he bestowed to this place.

This is all from God and He used as an instrument our beloved Executive Minister

so that the Church will spread here.

The three new houses of worship in Thaba Nchu,

Ha Fochane,

and Ladybrand

are only parts of the series of projects here in the African continent.

After the dedication to God of the house of worship of the Local Congregation of Ladybrand,

a huge Aid To Humanity event was held.

Manyatseng

this is considered as the poorest community here in the municipality of Mantsopa,

in the province of Free State, South Africa.

This venue of the Aid To Humanity activity is only a few meters away from Manyatseng

where the poorest residents of Ladybrand live.

During the activity (Lingap) the need of the residents here can be truly felt.

Like the Aid To Humanity that was held in Maseru in Lesotho,

the giving of aid to the residents was also peaceful and orderly.

Through a video presentation, both the residents and former pastors of different religions

the giving of help of the Church Of Christ

and its victories in the many aspects of services to the Lord God.

The leaders of the town of Mantsopa also extended their gratefulness

for the Church Of Christ's contribution to their community.

Brother Eduardo V. Manalo wants to extend not only this temporary help

but to provide permanent livelihood and housing projects as well.

We saw how poor they are.

It is important that we join hands in order to fight poverty.

At present, the Church Of Christ is already established in 139 countries and territories...

... and like what can be witnessed in different places,

in the neighboring areas of South Africa and Lesotho,

the [Church Of Christ] continues to show concern for our fellowmen

especially when it comes for the sake of their spiritual life.

We are truly thankful to our Executive Minister

for their continued help and pastoral visitations here in the District of Africa.

This brings us joy and renewed faith

because we earnestly feel his love, concern, and help,

and we see that Brother Eduardo is God's instrument

for the further growth of the Church Of Christ not only here in the District of Africa,

but throughout the whole world.
