Wouldn't it be great to go out on a summer day and not hear the noise of a demolition team tearing up the road? There have been ways out of this devised including a jackhammer with a shield over the cutter at the road that seals out the noise, they even have a hammer that is a sort of clamp to reach over the window or wall top and improve the concrete silently by clamping it, and this has been applied to road machines to first use the weight of the truck which the hammer is well connected with. The mass of the machine presses down into the concrete and then the hammer clamps in to the road like the usual wall clamp using the pressure of the weight of the truck to achieve enough force to make a big enough dent in the road to then be able to quietly clamp the concrete. Another innovation to reach into the concrete for walls is to drill into the wall with two drill bits with counterrotation and then the bits themselves or parallel bits or other clamps in the holes drilled disentigrate the room or other stuff. Unlike the truck mounted clamp the inventor says this is portable and lightweight, and no doubt it could be used in place of the truck mounted machine. This is somewhat loud but much quieter than a conventional hammer of this sort and faster in labor so the overall sound is lower because it just takes 15 minutes to demolish what was a 2 hour labor before.

..There is the new idea of the skyscraper used in the urban areas for agriculture and aquaculture. Some people may want fresh produce right away, if it's on sale from Brand Y at 49th floors and 87 cents. The problem here is if land is cheaper in the country, and it always will be, why not just build it there? This way more people will move to the country even if nobody lives in the country!
