Sun-Assisted Desalination. A Canadian startup has built a pilot desalination plant in Vancouver that uses a quarter of the energy of conventional plants to remove salt from seawater. The process relies on concentration gradients, and the natural tendency of sodium and chloride ions–the key components of salt–to flow from higher to lower salinity concentrations. If the system can be scaled up it could offer a cheaper way to bring drinking water to the planet’s most parched regions while leaving behind a much lower carbon footprint than other desalination methods.
“We’ve taken it from a benchtop prototype to a fully functional seawater pilot plant,” says inventor Ben Sparrow, a mechanical engineer who established Saltworks Technologies in 2008 to commercialize the process. “The plant is currently running on real seawater, and we’re in the final stage of expanding it to a capacity of 1,000 liters a day.” Today most desalination plants are based on one of two approaches.
P3 BioSand Bag Water Treatment Filter. Step 1: Help us to place 10 of our organic community water treatment systems as showcase models; to benefit 1000 people now drinking infected, dirty water. Thank you to all of our Indiegogo contributors! We will be sending 2 of our P3 filters to Trailblazers in Cambodia and you made it happen. We will document the installation and post updates on our website at: biosandbag.com. Your perks will arrive shortly. Thank you again for your support! Sincerely, The P3 BioSand Bag Filter team Don, Roy and Lisa The P3 Story and Mission The P3 BioSand Bag Filter is a lightweight, portable, highly effective community water treatment system for populations that lack clean water.
Inspiration for the P3 came from a tribal elder in Ghana who had seen many well intentioned efforts from the West go awry for lack of practical design, understanding of the end user, replacement parts, etc. The mission was clear: The P3 in Varanasi, India - the River Ganges What do we need the funds for? The Impact. Updating Archimedes. Short Summary The water crisis in Africa is not just a drinking water crisis — it’s also a food crisis. Available seeds are loaded with complex and sophisticated genetic technology just waiting for the right conditions to multiply and produce food, but they need water to work. Water in arid climates is often just out of reach for crop irrigation and so food shortages turn out to be technology shortages.
This all started when a mechanical engineer from Denver took a trip to help drill water wells in Niger Africa. Virtually on the banks of the Naimey River he witnessed hunger and thirst in primitive conditions. Locals, subsisting in dusty villages less than a mile from a flowing river, could not grow enough food. With your help, Africa is about to get an update!
Fast forward to Denver Colorado where a few of us have developed a way to bring this updated technology in a cheap sustainable way to Niger Africa. This pump works day and night! What We Need | What You Get The Impact Partners. Clean drinking water for the 3rd world. Short Summary My name is Moty Brill, i am an Israeli scientist holding a Ph.d in Nuclear Engineering. During 2007 I started to look into wave energy and developed a device that uses the energy to produce electricity. At that time Israel suffered from water shortage and I modified the design to desalinate seawater. During 2011 I've met a member of government of Solomon Islands and decided to modify the design for 3rd world, isolated villages. People that die each day from lack of drinking water and diarrhea. It moved me because nobody cares about them. This will not be a "money maker" project; it will not be a huge project with hundreds of workers.
I am looking for funds to build the first ever solution for those human beings. Help me save lives. What We Need & What You Get I am looking for $650,000 which is my best estimation of the cost of detailed design, building the device in Israel and transfering it to the location in the Solomon Islands. You are buying real drinking WATER. The Impact. New Invention Makes Ocean Water Drinkable. Susanne Posel Occupy Corporatism July 2, 2013 Chemists with the University of Texas and the University of Marburg have devised a method of using a small electrical field that will remove the salt from seawater.
Incredibly this technique requires little more than a store-bought battery. Called electrochemically mediated seawater desalination (EMSD) this technique has improved upon the current water desalination method. Richard Cooks, chemistry professor at the University of Austin said : “The availability of water for drinking and crop irrigation is one of the most basic requirements for maintaining and improving human health.” Cooks continued: “Seawater desalination is one way to address this need, but most current methods for desalinating water rely on expensive and easily contaminated membranes. Kyle Krust, lead author of the study said: “We’ve made comparable performance improvements while developing other applications based on the formation of an ion depletion zone.
