MIT Group Used Solar Energy To Make Salty Water Drinkable In Off-Grid Areas

By Eleanor Goldberg for The Huffington Post:  ​While there are many technologies out there than can effectively remove salt from water to make it drinkable, most are expensive and rely heavily on electricity –- rendering them all but useless in remote, off-grid villages.
That’s why a group of engineers from MIT, backed by Jain Irrigation Systems, set out to invent a system that relies on solar energy to bring clean drinking water to rural areas in India, The Washington Post reported.
About 21 percent of India’s communicable diseases are related to unsafe water, according to the World Bank. According to MIT researchers 60 percent of India has brackish groundwater -- while not toxic, that water is too salty to be ideal for human consumption.
The group, which took home the first-place Desal Prize last month in the “Securing Water for Food” challenge, used a method called electrodialysis, which relies on electricity and ultraviolet rays, according to the aid organization.
 
The first-place winners were awarded a $140,000 grant.  Cont'd...

TRA SNOW AND SUN - SOLAR TILE MOUNT

TRA SNOW AND SUN - SOLAR TILE MOUNT

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
