the new glass i invented has microchips inside and many tiny air holes on the windows. i made it with cdm and young materials. how about that? its special, isnt it? now id like to introduce the new glass i invented recently!

you will think, whats the use of chip? the purpose of installing the chip is to make the windows present different translucent and beautiful images throughout the year, which makes people feel comfortable and beneficial to body and mind: in spring, there will be a scene full of spring on the glass, willows sprout and grass turn green. in summer, a hot atmosphere appeared on the glass. the sun was about to have a high fever. a child was eating ice cream while walking on the street. in autumn, there will be a bumper harvest. the straw will turn yellow, the rice field will turn yellow, and the red persimmon will be very bright when it is hung on the tree. in winter, there will be a happy scene, a group of children make snowmen, a group of children have snowball fights. people will think that it costs too much electricity to be on all day. no, i installed miniature led on it, and installed solar panels and wind turbines on it, which can solve this problem.

as the name suggests, a vent is a small eye for ventilation. but the air holes on my new glass not only have the function of ventilation, but also have other functions, such as: cool air in summer, hot air in winter, plasma purification, oxygen generation and so on.

the materials are also different. i added cdm and young materials to them. the so-called cdm material is the chemical material i have recently developed, which makes the glass extremely hard; the so-called young material is super softener. together, the two materials are bulletproof, unbreakable and extremely hard. even if broken, young will soften the glass, so you wont scratch your hand!

this is my new glass. what about?

in the future, science and technology in the world is developing rapidly. the multifunctional robot i invented was one of the most advanced robots at that time.

in the past, when building high-rise buildings, some reinforced concrete was often transported to very high places. this requires workers to take the elevator to transport the cement. but this is very dangerous. if there is a slight accident, the elevator will fall down and kill people. but even if it is so dangerous, the workers still have to do so. with the increase of high-rise buildings, how many workers will be killed every year! in order to solve this problem, i invented a multifunctional robot to solve this problem. the robot is 40 meters tall. 3 meters, 30 meters long arm. it can move 70 tons of steel bars to 50 meters high. he is a good builder of tall buildings. does it need electricity? of course, it needs electricity, but it can use solar panels to convert sunlight into electricity, so it doesnt need charging. just use the remote control to control it. press the red button and it will start to work. press the yellow button and it will move reinforced concrete to build a building. if you press the red button again, it will start painting. with this kind of robot, engineers are much more relaxed, just take the remote control to command it.

this kind of robot can also carry out high-rise fire fighting. as long as you press the green button, a few streams of water immediately burst out of its arm to put out the fire. because it has a protective film on its surface, it will not be burned. its protective film can also convert sunlight into electricity, which is equivalent to a solar panel. but just press the pink button and it stops working.

this kind of robot can build high-rise buildings, but also high-rise fire fighting. is it convenient?
