Well, they are, at least, that is the other name for them. This is a mechanism that ought to use a rotating helical screw blade. That is called a flightling and they are mostly used to move granular or liquid material around. And most times, they are used in a lot of bulk when handling things in this industry. They are screw conveyors.
Luckily, they work really well for what it is that they do for the companies that need them. Machines that work well are always going to be needed in time and when the time comes that they will not be any more, humans will find a way to replace them with something better.
On the other hand, where are we going to throw all these big things away to? Are they just going to get deserted somewhere in a dump and contribute to more of the trash on this planet? Will that not makes the planet even more dangerous and sick than it was before?
Because as much as we like to make and invent these things and the machines that are supposed to make our lives easier, we sure do like throwing them away too. And pretty efficiently, if the dump has anything to say about it.
Unused cars with their metals and engines that litter around the place, nowhere to go so they have to stay dormant on the ground until the earth swallows them all up and stay dormant underground instead. And they would be contributed to more of the trash that we already throw unto this land.
We really like to litter. Even if we say we hate it. We cannot help but litter if we were being honest. It is what we do. Because we use a lot of things and then throw them away once we are done with them. This goes the same for food, you know.
After it is done staying in our body, it goes out of us and where does it go? The sewers. And where will that dirt and gunk go? Well, your answer is as good as our to be honest. But for now, these conveyors are being used and still are very much useful. For now, we could still see them as something that does not have to be thrown away.
Later, when we have something better and they have used and exhausted up all of their uses, we are going to throw them away too. And we have to do a total recall on all of the things to put there with the same purpose because they will be thrown too. But they have served their purpose.
Years and maybe decades or centuries of being in use to us in the ways that they have been used. And then they will be extinct. Just like the first ever computer made. Because now we have found ways to make even that easier and lighter. We have laptops now and then tablets and phones. Who is to say that the laptops will not also go the same way?
