looking for cheap cooling suggestions

Hi I am thinking of running a vaccum air pump to take the cool air in my basement and take the air into my bedroom. This would be quite easy for me to do since there is a channel in my attic running vertically down to the basement. All i would then have to do is place a vent in my bedroom ceiling.
Can anyone confirm that this works (it seems logical that it would) and suggest the type of pump and piping to use as well as some king of thermostatically controlled power strip.
If it does work, why is this method not standardly installed with central A/C ? My AC has a fan that only circulates air in the same zones.
Taking this vacuum idea further, if I run a looped length of metal piping (has to be a good heat conductor) a few feet undergroud in my backyard and pump hot house air through it, would it come back considerably cooler?

Why not use a blower to move cold basement air upstairs? Vaccum air pump?

Do you have more than one A/C? How does it avoid mixing the air from various areas?

Yes, but unless the pipe was pretty deep and extensive, and the volume was large, you wouldn't lose enough heat to matter.
This a troll? Vacuum pumps, pipes in the ground...

The humidity might make you more uncomfortable if the basement is humid

It can work to some extent. Oftne, the cooler air is also more moist and not so comfortable. You also have to bring in air that is going to be warmer to replace the cool air you took out. After a few air exchanges, the cool air may not be so cool any more. It will take some time for the basement to absorb the heat and afer a time, it won't be neary as efficient as the first day.

Duct and a blower should work.

Because it is not all that practical for a long term and does not remove humidity the way a mechanical AC does.

Deeper you go and the longer you go, yes, it can work. I don't have a clue how well, but you can do some calculations based on mean temperatures fo ryour region. It is also possible to extract heat in the winter to heat a house with geothermal heating sytems.

SOunds like an excellent way to heat your basement in the summer.

You're confusing heat with temperature. Two different things.

A vacuum pump is optimized to produce vacuum, which is way different than moving a large volume of air, which is what you need to do here.
Assuming you can move a large volume of air from the basement, yes it will temporarily cool the living space. But once you move the existing air out of the basement, which doesn't take very long, it then takes quite a while, hours, for the air in the basement to cool down again.
When I was a kid, we didn't have central air. Sometimes in the summer, we'd take the blower cover off the forced air furnace and run the blower to do what you are trying to do. It gave a brief but noticeable cooling effect. Howerver, after about an hour, the cold air was gone and maybe an hour later it was time to open the windows.
The other problem with this is that it draws hot humid air into the basement, where condensation from cold water pipes, etc may become a problem. Plus, if you did it regularly, it might introduce enough moisture that would support mold too.
