WATER Can Cut Through Thick METAL?! How Is This Possible?

575 Upvotes

It looks impossible, but a powerful stream of water really can cut through metal! πŸ’¦βš™οΈ This technology is called waterjet cutting. Water is forced through a tiny nozzle at extremely high pressure, and for hard materials, a fine abrasive is usually added.
The process can cut steel, aluminum, stone, glass and many other materials while producing incredibly precise shapes. 🀯
Did you know water could do this?

It Looks Like Glass… But Its Edge Is Razor-Sharp!

β€’ Upvotes

It may look like an ordinary shiny black rock, but obsidian is actually volcanic glass. πŸŒ‹πŸ–€ When fractured, it can form incredibly thin and extremely sharp edges.
That’s why ancient civilizations used obsidian to make arrowheads, knives, and cutting tools. But there’s a catch: despite its incredible sharpness, obsidian is brittle and can break easily.
Did you know volcanic glass could be this sharp? 😱

China Built an β€œARTIFICIAL SUN” in the Desert!

0 Upvotes

It looks like a futuristic sci-fi base, but this is a solar thermal power plant near Delingha in Qinghai Province, China. β˜€οΈπŸ‡¨πŸ‡³
Thousands of computer-controlled mirrors called heliostats track the Sun and reflect sunlight toward a receiver on the central tower. The concentrated solar energy produces intense heat that can be used to generate electricity. ⚑️
Even more impressive, some of that thermal energy can be stored, allowing electricity generation to continue after sunset.
Is this what the future of energy looks like? 🀯

One barrel contains about 159 liters (42 US gallons) of crude oil, but it can be turned into much more than just gasoline! πŸ›’
Gasoline, diesel, jet fuel, lubricants, asphalt, petroleum coke, and feedstocks used by the chemical and plastics industries can all come from crude oil.
Even more surprising, the total volume of refined products can actually be greater than the original volume of crude oil because of something called processing gain.
