If the water is on a hilltop, energy must have been used to pump it up there from wherever it originates. On the other hand, when used it will flow downhill without pumping.
So that the water can be gotten without a pump. Using gravity to put out a fire when the power has gone is smart. Having a water system that distributed by gravity is brilliant.
Most water towers are built with two purposes in mind. One is to provide a storage facility for potable water, the other is to provide water pressure for the system. As such, the towers are typically always 'releasing' water. There are normally a couple of one way valves to insure there is no 'backwash' to contaminate the water in the tower, but the tank is providing pressure in much the same way as the tank of a toilet.
Yes, but modern high efficiency wind machines can turn in very slow winds. Also they are built on towers that place them in an area where wind speeds are frequently much higher than near the ground.
No.However if a dam is built somewhere in the canyon (canyons usually have rivers flow through them - which created the canyon) the water released through the dam can create electricity (hydroelectric power).
Yes, the casio watch has a built in shock absorber.
It is called a causeway. It was built by they Aztecs.
For the pumps
the petronas towers were built in 1998
The Martello Towers were built in 1846... that is what i know :P
it was built in 1975
it was built in 1975
The twin towers were built in 1973.
the twin towers were built by very large machinery and they also took a while to build them
no not yet
the petronas towers were built in 1998
Large towers are built to provide water to keep equipment cool.
to honor the towers when they were there and to keep 9/11 in rememberance
Good storage containers are built in a manufacturing plant.
