Do it Yourself, DIY hobbyist-made homemade, portable lasers that can melt even steel.

Laser is not a toy. One single laser LED can burn the paper. In the second film, you see that the 1W laser LED can put newspaper on fire. But, the most powerful hand-held, homemade laser can make much more. The YouTuber named Drake Anthony made that thing. And its introduced in many media pages. The first film is about that, the most powerful hand-held laser. 

The 250 W laser uses LED-based technology. That makes it possible to make portable lightweight, high-power laser systems. That laser can melt steel and those things make them very dangerous in the wrong hands. The laser system that shoots a laser beam through the laser lead-made laser beams binds that energy into those beams. This effect is known as the maser effect. 

The requirement for that thing is that laser rays that come from the bottom of the system are stronger than beams that come from its sides. Another way to make that system is to use high-power holograms. Those high-power or high-energy holograms inject energy into that laser beam. And that can raise its energy level to higher than the creator predicts. Another way is to aim multiple laser- LEDs at the same point. 

In the wrong hands, those portable systems can be dangerous. They can be used to cut electric wires. And if they are aimed at things like aircraft. They can scratch to the wing. That means those systems can be dangerous and at this time dangerous means both purpose and non-purpose damages that the high-power laser rays can cause. A single laser LED that injects energy into organs like eyes or skin can cause deep burning injuries. And that makes those systems dangerous.

When we think about military applications, high-power portable lasers can make a similar revolution as drones. The ability to interconnect laser communication lasers and laser weapons makes it possible to create systems. They can also destroy drones and other targets. Laser systems can drill holes in cannons and engines. And that makes them ideal for sabotage. 

If multiple drones aim laser beams at one point, that can destroy even large, and well-armored targets. Those lasers can cooperate with drones. If the drone has a mirror and the laser beam is aimed at it, that system makes it possible to shoot laser beams around the corner. The mirror drone that hovers above the battlefield can aim those laser beams over the hills and other blockage. 

The fact is that laser weapons are also deadly tools. If somebody uses a laser rifle as an assassination tool, there is no bullet that nobody can compare like police normally make in gunshot cases.  High-power laser rays that are shot at the water balloon can cause extremely powerful explosions when they cause sudden vaporization of water. 

The power of that explosion depends on how powerful that laser ray is. And how fast it can transfer its energy to that water. If that evaporation happens very fast. That can create a powerful pressure effect that can damage things. That is around it. So that makes it an effective stun gun.

Genetic engineering is the ultimate tool for people





Genetic engineering brings new species in front of us. The genetically engineered spiders that create silk that glows red in the dark is the brand new thing in the world of genetic engineering. Genetically engineered species can make many things that are impossible for regular technology. There is the possibility to create insects that deliver vaccines. The mosquitos that carry deadly malaria and other diseases can also carry vaccines. The idea is that. 

The vaccine is made in the engineered mosquito's salivary gland, and it helps the immune system detect malaria parasites better than without that vaccine. The malaria vaccine can be the shell antigens of the malaria parasites and the immune booster that causes an immune reaction against those antigens. 

This thing can be a very interesting way to use genetically engineered species in areas. Where there are no vaccine styluses. Or people are hard to reach.

But then we can go to the biorobots like microchip-controlled bugs. Same way. Microchips can control bugs. Those things can control things like spiders. The remotely controlled spiders can make the silk canvas.  But then we can think, about what remote-controlled spiders like black widows can make in wrong hands.

Genetical engineering makes it possible to create things like mosquitos, wasps, and bees that produce the same poison as the black widow. Those things are extremely dangerous in the wrong hands. And microchip controlled bees and other bugs can attack people. Genetically engineered parasites can create things like tetradotoxin. Which makes it possible to create human robots. 

The most futuristic versions of biotechnology are beyond your wildest dreams and they are worse than your worst nightmares. 

Genetic engineering makes it possible to create the most interesting versions of the hypothetical intelligent bugs. Those creatures can be spiders spider silk involves bacteria that can transmit those spider's nervous signals to each other. 

But then we can remember Joseph Stalin's idea of "monkey soldiers", or "dog soldiers. The soldiers with monkey brains. The idea is that the dog soldier follows precisely the orders that it gets. The microchips in the brain control that creature. The control antenna can look like a helmet or some kind of metal bandanna. 

The first experiments with this bizarre idea were made by Ilya Ivanovich Ivanov. Ivanov tried to transplant the dog's head to a monkey's body. That person tried to create a human-monkey hybrid. Brain implants and genetic engineering make it possible to create real-life monkey soldiers. Sometimes Stalin and Hitler called those hypothetical soldiers whose brains are like dogs' brains and who follow all orders that they have. 

Monkey- or dog soldier is the term that means the soldier or creature that can only follow orders and doesn't think themselves. The brain-implanted genetically engineered soldiers can act as biorobots. The monkey-soldier can be like some kind of "predator" from the horror-action movie, where masked alien creature hunts people on Earth. The idea is that this kind of creature can have a strong body. But the brain-implanted microchips can control that creature's body.
