Is this true or fake INVINCIBLE cloak

Obviously fake otherwise this would be the greatest invention since the wheel and the inventor would be the world's first trillionaire!..

With that being said some cloaking is currently possible with many tiny cameras simulating and projecting the environment onto itself however it wouldn't be on a piece of magic Harry Potter shawl like that. It would have to be on something more substantial with its own power source etc.

Let's assume that a true invisibility cloak actually works. How will the person behind the cloak see outside of it if no light can penetrate the cloak?

couple months ago we have news about China purported plan to divert water from Tibet Yarlong Tsangpo aka Brahmaputra. Now our good colonel claim to have proof Not sure if he engage in fear mongering or He is into something here

Images show China may be using a secret tunnel to divert Brahmaputra water into desert
13 December, 2017


China blocks Brahmaputra completely | Vinayak Bhat
Latest satellite imagery shows the river Brahmaputra disappearing into a 900 m underground tunnel in China.

In what is perhaps the first evidence of a possible diversion project by China, latest satellite imagery shows a massive new dam on the Brahmaputra river — Yarlong Tsangpo in Tibetan — with an underground tunnel that seems to engulf the entire water flow for almost one kilometre.

The Brahmaputra is sacred to Indians and Tibetans alike and has its origins in the Angsi Glacier in Purang county of Tibet. It has been in the news for water reportedly turning black on the Indian side and in connection with Chinese plans to divert it to the arid lands of the Taklamakan desert.

Although the Indian government has said that there is no evidence of any water diversion project, satellite imagery from 26 November 2017, courtesy US commercial vendor of space imagery DigitalGlobe, indicates a new project in an advanced stage. This report – based on latest satellite images — examines only the actual ground position. Measurements are made on very low resolution images and may not be exact.

NEW PROJECT

The available images show a new 200 m wide dam that seems to have completely blocked the water of the Brahmaputra. The entire river seems to be forced into two inlets of almost 50 m width each towards the west of the river. The water flow comes out after around 900 m downstream in two outlets very similar to the size and shape of the inlets.

The project – currently under construction – is located 60 km east of Shannan township as the crow flies. The location is also almost 40 km east of Sangri county.

What has raised questions about this project is that another project – Tsangmo or Zangmu Dam — has recently been constructed just 13 km downstream. This run of the river dam was made operational in end-2015 and has a capacity of 510 MW power production. Beijing did not pay any attention to India’s objections to the .

POSSIBLE DIVERSION PLAN

The construction of another dam 13 km upstream of Tsangmo which diverts the entire water inside the mountain suggests that its purpose may not just be hydropower generation. The purpose of this project is possibly for diverting a portion of the Brahmaputra to the parched areas of Taklamakan desert.

The geography of the area, when studied deeply with the elevation profile, clearly indicates that China may actually be planning to divert the waters of the Brahmaputra approximately 1,100 km northwest of the project site.

The path indicated on the image below shows the possible route of the underground tunnel which does not touch any water body on its way. The height difference at the project site and the point of Taklamakan desert suggest that a clear downslope will be available for the water to flow naturally without any additional constructions for large storage wells in between.

India being downstream of the Brahmaputra has full rights over its waters and any diversion of water from this river could likely hurt Indian agriculture. During any emergency, a sudden release of water from this project can also cause havoc on the Indian side.

BLACK WATERS

Satellite imagery shows that polymer resin adhesives are being sprayed by China all around this project area as a dust suppressant system. The resin adhesives are commonly used for large construction projects but are never used for projects near water, according to some water projects construction engineers, since these polymer resin adhesives are said to be harmful to humans and animals.

The resin sprays have been observed over the last two months. The rough estimate of time for water flow to reach India from this project location is 15 to 20 days. The colour of the Brahmaputra water in Assam acquiring a darker shade, according to reports in the media, could possibly be due to the use of these resin adhesives at this project site.

CONSTRUCTION IN FULL SWING

Satellite images clearly show stone crushers and cement plants at the site. The products of this facility are obviously used inside these tunnels for construction purposes. The material being quarried from inside these tunnels is being piled along the river up to the road level. Most of the stones have been crushed to different sizes and some of it may be pushed into the river along with the water flow.

A large number of tippers and other vehicles are seen carrying material to and from this area. An administrative area is also seen east of the project with a large number of red-roofed houses and barracks, possibly living quarters for staff and may also contain administrative buildings.

China is preparing for a trillion-dollar autonomous-driving revolution

• China is eager to develop smart cities to cater to an autonomous-driving revolution.
• Nearly 300 Chinese regions and have already introduced projects for "smart cities" controlled by artificial intelligence that can be optimized for autonomous transportation.
• In addition to autonomous driving, ride-sharing and ride-hailing services are projected to generate a collective $1 trillion in revenue by 2040.

China has begun preparing programs and cities for an autonomous driving revolution expected to generate $1 trillion in revenue globally, .

Nearly 300 Chinese cities and regions, including and , and have already introduced “smart-city” projects controlled by artificial intelligence technology to enhance daily life, SCMP said.

Smart cities use cloud-based technology to integrate across several industries, including transportation, health care and public security, .

Ninety-three of the smart city projects are focused on transportation, according to SCMP, and could potentially use its connected infrastructure to build the number of driverless cars and shared-driving models on the road.

In addition to driverless cars, increased usage of ride-sharing and ride-hailing services are projected to generate $1 trillion in revenue for suppliers globally by 2040, latest industry figures indicate, according to SCMP.

China, the world’s largest market for electric cars, has sought to position itself to spearhead the future of autonomous driving.

“The combined impact of mobility services, driverless technologies, electric cars and government policies [promoting them] will propel a national transformation in personal mobility,” said IHS Markit executive Jim Burkhard.

, China is poised to set up an autonomous-driving market faster than other countries due to its ability to make regulatory decisions quickly. Michael Dunne, president at US-based Dunne Automotive, told CNBC: "The Chinese government can, and will, facilitate autonomous driving sooner than we will in the United States," Dunne said.

In June, Shanghai opened the country’s , where its trialed about 200 vehicles across nine miles (15 kilometers) of test roads in a closed zone at Shanghai’s international automobile city, the government said in a statement.

The test zone uses cameras, communication bases, and radar systems to help intelligent vehicles drive in nearly 30 simulated environments.

Shanghai is expected to build an intelligent-vehicle network covering about 62 miles (100 square kilometers) by 2020, the government said, adding that Shanghai will explore the possibility of connecting to major transportation junctions within the city.

In September, Chinese search giant Baidu announced a $1.52 billion (10 billion yuan) autonomous-driving initiative called the "" as part of a broader plan to spread technological advancement of autonomous vehicles.

The Apollo Fund will invest in 100 autonomous driving projects over the next three years, Baidu said in a statement.

Enviromental impact must be the first concern as the Ganges-Brahmaputra delta is one of the biggest in the world with huge biodiversity.Although this diversion might have positive impact to millions of Bangladeshi people who are forced to relocate or simply drawn during moonson period every year,as the whole country is located exactly on that huge delta.I don't think that Bangladeshi government is able to do something due poorness,or Indian government has any intention to do something about this issue due political reasons.Best solution is always in the middle

Well, it is within China's territory, so in theory China could do what is the best for them. India could protest whatever they like, but at the end of the day nothing substantial they could do really ... unfortunately

Just a thought, what would be the impact to India if the diversion is "only" 5-10% of total water flows?

It comes down to the diesel used. Ultra low sulfur diesel (I designed a couple of those plants back in the day) release less than 1% of sulfur from a tailpipe than regular diesel. I did some clean coal projects back in school, efficiency is higher than normal coal by factor of 2.5, but still much lower than diesel.

Coal produces more CO2 than other hydrocarbons due to its lower energy density. Your article even said the efficiency of coal is 47% max right now. For gasoline/diesel it is in the 90% range. But China got literally 200 years of supply for coal So they will continually try to improve their coal plants. Oil and gas are imported, and that what they to replace. That's what I think is their motivation for electrification. I don't buy the whole narrative on EVs being better for the planet.

I suppose you were referring to gasoline/diesel plants? Car combustion engine efficiency ranges between 20% to 40%.

Yes. Diesel combustion for power generation is extremely efficient in the newer designs. Natural gas is even more so, there are plants pushing close to 99% efficiency.

Then EV makes sense then

Much higher efficiency and better/easier pollution control

Im not against EV if the energy comes from an efficient source like natural gas. Unfortunately for country like China where majority of energy is from coal, EVs are dirty. If you are in Quebec where power is all hydro, then great....assuming the car will start in the winter.
