One of the company that got funding is KFP rainwater harvesting. The system gathers large amounts of rainwater underground using a durable plastic sheet. More details can be obtained by here http://www.varshajal.com/
Oil spillage Clean up
The X Prize Foundation, a non-profit organization announced the winners of the two companies Team Elastec of Illinois and NOFI of Norway. They where able to clean the BP OIL Spillage from the gulf coast the most efficient way. The conditions X prize foundation put forth is that the Teams should skim minumum of 2500 gallons per minute of oil from the surface of the ocean water with a efficiency ration of atleast 70%.

Here is a a sustainable and useful idea for those living near the sea to use ocean water to get pure water. A clever design by Gabriel Diamanti gives 5 liters of fresh water from salt water. The method is very simple. He built a clay pot, a solar plate to heat and vaporize the salt water for desalination (vaporizing salt water) , a metal base and collecting vessel. Sun heats the salt water and condensation takes place. The water vapor is then collected at the bottom where it is cooler than on the top. This water is pure water and drinkable. Salt and other waste is cleaned out from the top for reuse of the same for more water. Five Liters of water can be collected on a good sunlight day. This idea should be made popular in our country since it is very cheap and effective way of collecting pure water in small scale by villagers. The following links gives you the pictures and the idea of how to build one for yourselves.

Refrigeration by sunlight
Science daily carries a article on how sun’s rays are used for cooling food that is kept in a fridge. The process involves heating water to 200 degrees F and then uses the heat to drive a compressor that lowers the temperature of a refrigerant in the fridge. With very hot climate in India I think this is a good solution of keeping farmers vegetable and fruit crops fresh until they are sold in the market. This method is environment friendly, reduces the usage of electricity to minimum.
I’m hoping that somebody takes this idea to implementation stage. The details about this process can be read at http://www.sciencedaily.com/releases/2010/05/100503111531.htm
The MEDISCO project (Mediterranean food and agriculture industry applications of solar cooling technologies) has built several of these solar refrigeration plants in Mediterranean countries where sunshine is plenty. Engineers are using concentrating collectors to direct the sunlight onto an absorber that heats water. check more details at http://www.medisco.org/about/
“SHE ” is the first a charity that raises fund to educate girl students in developing world. http://www.shesthefirst.org/
Do something is a effort that gathers students to help others. Check more details here http://www.dosomething.org/
A innovative projects called “Live below the line’ https://www.livebelowtheline.com/ asks celebrities to live below poverty line life style for a budget of $1.50. It already attracted 25 000 people to experience poverty real time. The money raised by this effort will go for funding charities focused on hunger and the developing world, http://www.unicef.org/ and malaria no more http://www.malarianomore.org/
Fisherman and Fish farmers harvest more fish than what nature can withstand. By fishing too much the eco balance of the ocean is disturbed. In order to know where fishing is done too much or too little researchers have come up with the idea of using Google earth as a tool to know how much fishing has being done. A report http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0030546 says that “Examining the coastline of 16 Mediterranean countries for signs of the cages in which fish farmers raise their herds, the researchers estimated the 2006 production at 225,736 tons, a shade more (but not a statistically relevant amount more) than the 199,542 tons reported to the FAO by fishermen. More than 90% of the coastline was well documented in Google’s map database, and the UN publishes extensive statistics on the ocean cage fish industry. That made accounting for the sector relatively straightforward compared to attempts at estimating fishing production for commercial, high-seas fisheries in intentional waters or subsistence fisheries.” http://www.cbsnews.com/2100-501369_162-20117650.htm
The use of Google earth is particularly very useful because the days of expensive use of satellite images are not required any more. Hope our state and central government agencies are smart enough to use Google earth images for various programs they conduct for agriculture, fishing and mapping towns and cities and other social needs.
Fresh water is a scarce resource and is estimated to be a $1 trillion business by 2020. check more here http://www.un.org/waterforlifedecade/scarcity.shtml Most of the clean Water that comes thru municipal pipes get’s wasted in flushing toilets or cleaning clothes or for many other household chores. Very little amount of clean water goes for drinking. This is a huge waste of money maintaining clean water all thru the pipelines which sometimes break and contaminate the clean water and thus causing more damage to health of the people who drink it. It requires large amounts of money to run a company to clean water and send it thru pipelines. This is again waste of money when very little amount of water is used for drinking.
A investment strategist Kevin McGovern found this problem as an opportunity to bring together materials science researchers and water experts from around the world to create water filters that remove the biggest health threats (such as pathogens, arsenic, fluoride, and other chemicals). They came up with a water cooler that can be hooked up to a kitchen tap or other supply pipe to provide quality water when and where it’s needed. With this he was able to eliminate the expensive process of cleaning the water and sending it thru pipelines and only 2% is drinkable at the end. The group has successfully installed water coolers all over Mexico and even the government of Mexico offices are all having one in their offices. In India and other Asian countries this is a big opportunity if some one can come up with the similar kind of idea or join forces with him to bring that technology to India. http://thewaterinitiative.com/
Man made Photosynthesis: In Another news by Nature Royal Institute of technology scientists have come very close to mimic plant’s photosynthesis process by creating a catalyst that can break water molecules (H2o) to Hydrogen and Oxygen .

A guy named Mike Bodge realized that every second some on twitter is mentioning about what time it is while tweeting something. By mining the time and what is told Bodge developed a clock called Chirp clock that tells you a mini story (a tweet) every minute. With this twist a dumb time clock becomes a story teller of what people are tweeting every second. The time will be displayed based on where you are on the globe and stories or tweets will be running in the background. When you are alone or bored this time piece becomes your story teller every second. Check out this cool idea in action at below links

Floating solar grids
While most of the solar energy is generated by panels that are sitting on vast areas of land , water that covers 1/3rd of the planet was lying waste until Solaris a Israel based company came up with an idea of floating solar grids in waste water treatment plants. The idea can be used in other places such as wastewater ponds, sewage treatment pools, dams, and reservoirs also. Solaris came up with this idea by accident. They are trying to solve a problem of concentrated solar panels heating up fast and in order to cool those down they realized the new idea of floating solar grids on the water surface. The water evaporated will cool the grids and also generates electricity while floating on the water surface. It is so beneficial to develop solar systems to be on water than on land since land is not available for huge solar plants to be established while we have vast oceans lying around us. With a combination of ocean thermal energy, solar and wind energy this idea can generate a viable business for enterprising business people. Get to know more from the following links
