Throughout the world, there have been several innovations to generate new portable clean water in developing nations. The latest of these innovations is WADI, a water purification system started by the Australian corporation Helioz.

According to Helioz’ research team, WADI is an easy to use, cost effective UV measurement device for solar water disinfection (SODIS). In short, WADI is a solar powered water disinfection system that operates “without the use of chemicals, batteries or filters”. Because of its pure use, WADI guarantees its users with safe, chemical-free drinking water.

The WADI device is simple and easy to use. A user simply fills in a PET bottle with water from any source, puts the WADI device on instead of the regular bottle cap, and exposes the bottle to sunlight and UV rays until the water in the bottle registers as clean on the device. If the water is still contaminated, the device will show a sad face to the user.

If the water has been purified, the device will register a smiley face on it’s small LCD screen. However, the device does face some challenges. Although the device shows serious advancement towards clean water around the world, it also has setbacks in areas where water sources and sunlight are scarce.

In areas where sunlight is scarce, the cleaning process might take up anywhere from 45 minutes to two days longer than normal. As a result people who are in desperate need for water resort to drinking contaminated, more accessible water, researchers say.

However, the self sufficient water purification system promises to take the world by storm. The project is expected to launch in developing nations in January 2014. Currently, Helioz is working on a funding campaign for the device.

The campaign will allow the company to create a further study on the effects the device has on remote villages such as Odisha, India. The study will also help the company customize their product depending on the area it is being used in.

Projects such as WADI show great promise towards completing worldwide water purification. However, only time, and user responses will tell if the project is a success.

U.S. Solar Company Expands International Development to Latin America
SolarReserve, a U.S.-based solar company, has announced its expansion into Latin America for international development purposes. The company opened up an additional office in Santiago, Chile, as part of an effort to “provide cost-effective, clean energy solutions worldwide.”

SolarReserve plans to focus primarily on solar energy opportunities in the growing mining sector throughout the region, and will also be developing large-scale concentrating solar power (CSP) projects, as well as photovoltaic projects.

Company CEO, Kevin Smith, stated that the move to Latin America was a logical next step considering the benefits of clean energy development in the region, including the abundant solar insulation, inclusionary energy policies, and the expanding mining sector. He also said that although hydropower and wind power are already established sources of clean energy in Latin America, solar is only more recently gaining a foothold.

Smith also stated that SolarReserve hopes the installation of solar energy will help provide a more consistent and reliable energy source to the region, along with a cleaner source of power from an environmental standpoint.

Australian crowdfunding site, ChipIn, is being used to raise money to provide rural Indian slums with solar powered lights. ChipIn has joined forces with Pollinate Energy, an NGO dedicated to providing sustainable and renewable energy sources to rid India of energy poverty. Pollinate Energy’s goal is to crowdsource funds to support the purchase of five franchises that will sell solar lamp kits for tent slums in Bangalore, India.

Pollinate Energy’s goal is to provide the community members with a month-long training program, initial hardware, and continuing support systems to ensure long-term success – as opposed to simply providing members of the community with solar lamps.

Crowdfunding has rapidly gained in popularity in recent years, and has become an efficient way to fund renewable energy projects in supporting energy-poor communities in developing countries. Pollinate Energy says that the funding is needed, as they found nearly “3,400 families without power in a 6-mile radius.” Information released by the government backs up these numbers, with a recent report citing that 1 out of every 6 urban Indian lives in a slum, a majority of which are not even connected to the power grid at all.
