How To Build A Solar-Powered Still To Purify Drinking Water

How To Build A Solar-Powered Still To Purify Drinking Water | Off The Grid News.

Step by step instructions to build a simple box that takes in open vessels filled with any impure water. The sun’s heat collecting in the box slowly boils the water, which condenses under the sloping glass top, and is collected in a tube at the edge. What is collected is pure distilled water. This simple device (and once you get the basics you can modify it for any range of needs… ) can deliver basic life-saving drinking water from the most polluted of sources, is inexpensive and does not need too much advanced skill to set up.. just spread the basic idea and you might just save a lot of lives in a disaster.

Satvik Parabolic Solar Cooker

Barefoot college, tilonia (rajasthan)

In 1965 a young post graduate student, SANJIT “BUNKER” ROY volunteered to spend the summer working with famine affected people in Palamu District Bihar, now Jharkhand, one of the poorest of India’s states. His urban elitist upbringing had distanced him from poverty and destitution. This experience changed him, and formed the determination to fight poverty and inequality. It became his mission. The idea of the SWRC (Social Works and Research Centre), Tilonia emerged from these concerns.

Bangladesh Hits 1 Million Solar Home Systems

"The Bangladesh story however, is particularly exciting because Grameen has singlehandedly shattered the energy ‘axioms’ on which the international policy community has relied for decades: Renewable energy is too expensive: Wrong. Even if solar makes sense the poor can’t afford it or they won’t pay: Wrong. The grid will come regardless so off grid, decentralized energy is a waste of time, money, and effort: Wrong, wrong, wrong. What Bangladesh does prove is that Carl Pope is right: deploying solar makes the most sense for off-grid areas where the economics are compelling and the need is great.

That’s what makes the next phase of the solar revolution even more exciting. That’s because today we are talking about 1 million solar home systems in Bihar, but tomorrow we could easily be talking about tens of millions in either Bihar or Uttar Pradesh, Indian states that have off-grid populations larger than most European nations."

10 Huge Lessons We’ve Learned From Solar Power Success In Germany

Read full article on CleanTechnica…

1. Feed-in tariffs can drive solar power growth like nothing else. 2. A more mature solar power market sells solar power for a much lower price. 3. More streamlined permitting works.
4. Feed-in tariffs democratize the electric grid.
5. Democratizing the grid gets residents informed and motivated about energy. 6. The grid will not fall apart at 5% solar penetration… or 10%… or 15%… or 20%. 7. Solar power brings down the price of wholesale electricity. 8. Even very grey places can generate a lot of solar power.
9. Even once solar power capacity is equal to 50% of electricity demand, utility execs, fossil fuel execs, their buddies in government, and their buddies in the media won’t stop fighting it.
10. People love the sun — they love clean, solar energy — and they always will.
