why don't we drain the oceans?

why don't we drain the oceans

by 1 centimeters per year

using solar powered desalination of seawater

then use solar power to pump

the freshwater in land where it is needed?

because 97 percent of the worlds water is salty ocean

water and not suitable for drinking.

ocean water volume is roughly 326 million cubic miles

(1.332 billion cubic kilometers),

according to a recent study from

the U.S. Geological Survey.

71 percent of Earth is covered in salty water.




water

2 billion people lack safe drinking water at home, more than twice as many lack safe sanitation

money

2 billion potential customers just waiting for us to supply them clean water

even if we charge $1 per year that would be $2 billion per year

if we charge $10 per year that would be $20 billion per year

if we charge $1 per week that would be $100 billion per year




salt

we have to mine for a quarter of a billion tons of salt each year that we currently use.

pipeline

The world's longest pipeline is 2353 miles.

the Interprovincial Pipe Line Inc. installation,

which spans the North American continent from Edmonton, Alberta, Canada through Chicago to Montreal:

a distance of 3787km.




solar power

Approximately 12000 TW (terrawatts) of energy

reaches the Earth from the Sun.

That is 1200000000000000 joules per minute

More energy reaches the earth from the sun in one day

than the whole world uses in one year.





Deserts

Seen from space, the majority of the Earth's surface is covered by

oceans – that makes up 71% of the surface of the Earth,

with the remaining 29% for land.

what percentage of the Earth's land surface is desert?

Deserts actually make up 33%
