Water opportunities

World is facing a severe water shortage and desalination of sea water is very expensive. Industrial desalination involves huge amount of electricity consumption that makes the business non profitable. If you can solve these problems of purifying sea water cheap or reduce the cost of making solar energy cheap so that it can be used in desalination process of water,  you will be solving the most challenging global problems and you can also make money in the process. Here is the challenges we are facing regarding water.

” A cheap way to extract salt from seawater so we can drink it? Several countries are already dealing with the impact of rising populations and shrinking lakes and wells without water. For example, in Amman, Jordan there is scarcity of water. Droughts in China , INDIA, Australia and Ukraine have led to crop failures, rising food prices and dwindling grain stocks.

In the middle of the 20th century, the world had about 4,000 cubic meters of fresh water per person per year, according to DHI Water group http://news.cnet.com/8301-11128_3-9925900-54.html#ixzz1Imw1VSbu . Now we’re close, globally, to 1,000 cubic meters per person per year — and 1,000 cubic meters per person per year is defined as water scarcity.

Since 97 percent of the world’s accessible water is in the ocean, inexpensive green technology like desalination — the process of turning seawater into fresh — would open up vast new sources.

Beef production accounts for 1.3 percent of calories consumed by the global human population, but cattle occupy 60 percent of the agricultural land. It takes 31.5 kilowatt hours and 2,500 gallons of water to produce a pound of meat. Grain for human consumption takes less than a kilowatt-hour and 25 gallons, according to various estimates.”

So now you know the impact you can make if you can find a cheaper way of desalinating sea water or finding a cheaper solar technology to generate enough electricity for all the industrial , agricultural and human use. Try your best and start finding some solutions. Good luck.
