These are the first clips from Lorin Symington's quest to establish the first solar fire powered bakery in Haiti.

With fuel costs on the rise in Haiti, baked goods are becoming more and more expensive. The team at GoSol..org is pioneering a new sustainable energy based business model that they hope will spread first in Haiti, then around the world.

Introduction to Prosthetics and their manufacture

Prosthetics are parts that fit into a human body to complete a function that has been lost/impaired. Ears cannot hear clearly; eyes have difficulty in seeing clearly; limbs have been cut off or were never present. Cochlear implants in the ear canal improve hearing; lenses are inserted into the retina to improve eyesight; artificial limbs aid walking and functioning of hands.

Polypropylene Film Replacement

Last June, I took part in the InnoCentive Challenge # 9933575 - Polypropylene Packaging Film Replacement. I submitted a written proposal for novel packaging materials to replace polypropylene films, providing a better biodegradability and the same or greater moisture barrier. Since the Seeker Scientists have chosen not to employ the solution that I submitted, I am now placing it in the public domain for all to see and use freely if it suits them.

I took part in the InnoCentive Challenge # 9933299 - 3D Printer with 10X Speed that was posted on Feb 28, 2014. The Seeker desired proposals for 3D printing with 10X the speed and was particularly interested in disruptive innovations to dramatically increase the throughput of 3D printers. I decided that this challenge suited me. Within three days time I had developed a solution based on my experiences in various fields and my understanding of how to eliminate waste.

Bamboo Tunnel Proof Of Concept

Bamboo Tunnel is an attempt to build a rectangular plan based tensegrity structure that functions as a poly-house for growing agriculture products under it.

Bamboo Grove

After I had shown the paper hub and plastic strut model, Vigyan Ashram, Pabal, invited me to construct a proof of concept Bamboo Tunnel that they could show case to nearby farmers. Vigyan Ashram is large-hearted in spirit but functions with many limitations on its budget. They were ready to provide me with all the labor and tools that I wanted, but did not want to spend any out of pocket money on the project. They had a bamboo grove on the site and invited me to use some older bamboo and some green shoot bamboo to build the tunnel. Even though such a structure would not have a long life, I jumped at the opportunity as the material was good enough for a proof of concept project. I am thankful to Vigyan Ashram for the support during the project.
