Demolished buildings and CO2 being used
A method that researchers first introduced in 2021 and made serious improvements over time may shift the construction industry to the greener side. As we said, concrete production has a large environmental cost. A big part of this is portland cement one of the main components limestone calcium by heating what it takes to get from high temperatures stems from.
Instead of using this process, Japanese researchers came up with their own method. calcium carbonate concrete It creates a building material called. I already do this existing concrete, rubble or collapsed buildings taken from air or industrial processes combining with carbon dioxide They are making it happen. The concrete blocks, or rather bricks, produced at first were quite small and flimsy.
Not only does the new method use old buildings to create new buildings, but the calcium carbonate concrete bricks themselves can be pulverized at the end of their construction life and the process repeated to create building blocks for new construction. The team’s Calcium Carbonate Circulation System (C4S) will next step up efficiency and will focus on the pilot production facility. The team also aims to build a two-storey house using calcium carbonate concrete bricks by 2030. Of course, it is not logical or possible to use the method put forward by the team everywhere. However, this method can be used in countries that are infertile in terms of limestone, such as Japan.

Those lighting effects had to be on the top, not just on the sides. In this way, the person using the gun will have to tilt his head to the side and there will be no hernia.

Yes, but a 6x scope works better for farther targets. You can also increase it to 3x when necessary 😀

Good against invasive pigeons. Grabbing a stick and chasing every 5 to 10 minutes was getting tiring.

They may have thought that it was unnecessary because the water it squirted would not hit the target like a bullet.

It would have been even better if a laser sight had been added.
