Here is a test of the rig in Tanzania.
Looks like the BYU rig might last for a while; only time will tell.
Kudos to the folks at BYU!
Despite what you may hear, manual well drilling methods have been used successfully for a number of years. The Terry Waller method (the so-called 'Baptist method') has been used by the SAIWI folks at UNR to teach those in developing regions how to drill and construct their own water wells. I know it has been used in Bolivia, Kenya, Ethiopia, and Nicaragua.
Here is a video of the Waller method.
