[00:00.10] From VOA Learning English,
[00:02.38] this is the Agriculture Report.
[00:05.56] Students at the University of Virginia
[00:08.60] have developed a new way of purifying water.
[00:13.08] They say it could bring improved water quality
[00:16.41] to millions of people in the developing world.
[00:19.97] They called it MadiDrop.
[00:22.41] Field testing begins recently in South Africa.
[00:26.26] The laboratory in which the MadiDrop is made
[00:30.25] operates like a kitchen.
[00:32.89] Workers add ingredients and mix, weigh, press and bake.
[00:41.42] What the workers are making
[00:43.46] is a ceramic disc that contains silver.
[00:47.45] When the disc is dropped in water,
[00:49.79] silver ions are released to purify the water.
[00:54.12] Ions are atoms that have an electrical charge.
[00:58.20] Testing at the University of Virginia
[01:01.74] shows that the disc produces clean, safe water.
[01:06.27] Beeta Ehdaie is a doctoral candidate at UVA.
[01:11.11] "It's not just about making a really great technology
[01:15.17] that effectively removes or kills bacteria and pathogens.
[01:20.22] It's about making a low cost, simple to use one,
[01:24.06] tailored to people in developing countries
[01:26.10] who don't have many resources."
[01:27.54] The students are experimenting with different sizes of MadiDrops
[01:32.27] to match them with different sized water containers.
[01:36.31] Why the name "MadiDrop"?
[01:39.28] The word "madi" means water in Tshivenda,
[01:43.56] a language of Limpopo Province in South Africa.
[01:47.54] There, fifty women run a factory that makes water filters.
[01:52.57] The university started the factory last summer.
[01:57.17] The women mix sawdust and clay to make flower pot shaped filters
[02:02.66] that they use to purify drinking water.
[02:06.26] The water flows through the filters
[02:09.26] is which trap bacteriaand solid particles.
[02:12.49] The factory sells the filters to local families.
[02:16.52] Manager Certinah Khashane says
[02:21.32] the work has changed the women's lives.
[02:23.87] "When they get money for those pots,
[02:26.98] they just buying school uniform for their children."
[02:30.94] But the MadiDrop is smaller and less expensive than the filters.
[02:36.42] Over the next few months,
[02:38.27] students will test the MadiDrop in South Africa.
[02:41.94] Maggie Montgomery is a water expert
[02:45.57] with the World Health Organization.
[02:48.52] Over Skype, she explained what field testing should show.
[02:52.90] "Do they find it convenient,
[02:54.35] does it have a certain taste they don't like to the water,
[02:57.88] what happens once it becomes exhausted?"
[03:01.32] If the testing is successful,
[03:04.36] the South African women will make and sell the MadiDrops.
[03:08.46] The goal is to expand such factories to other developing countries
[03:14.45] and improve millions of lives each year.
[03:18.69] Jim Smith is a UVA engineering professor.
[03:23.16] He leads the project.
[03:25.25] "Imagine a magic stone and you take this magic stone
[03:29.64] and you drop it in your water container.
[03:31.43] It purifies the water and makes it safe to drink.
[03:34.87] And then imagine that this magic stone only costs a few dollars.
[03:38.90] That's what a MadiDrop is."
[03:41.34] Professor Smith says he has received calls
[03:44.82] from companies that want to make the MadiDrop.
[03:48.26] And that's the Agriculture Report from VOA Learning English.
[03:53.47] I'm Christopher Cruise.
