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.
Today's op-ed by Paul Krugman in The New York Times titled A Permanent Slump? brings to mind the prediction by Buckminster Fuller that the world would be facing an economy which would have to be based on surpluses rather than a scarcity of goods and services. Fuller had laid a timeline of year 2000 as when this would happen.
The purpose of this page is to guide a beginner in geodesic domes as to how to go about building a 3V icosa geodesic dome. This has grown out of my correspondence with a young engineer who wanted to go about doing this.
Recently I made a mobile whose design incorporated the very difficult art of vertical balancing.
Afterwards I reached different conclusions. First, vertical balance has no value for an average viewer. Even when it is pointed out, he does not appreciate it. So 3 out of 7 nodes of my mobile were not adding any value to the average viewer.
The balance four were just not moving relative to each other. but were rotating in a plane. Very boring movement with no re-carving of space.
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.
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.
I have been making various sorts of mobiles for over 35 years now.
I learnt the art of balancing forks and spoons over the edges of cups and glasses at home.
When I was living as a bachelor in Calcutta, I found a book on Calder's mobiles at one of the book fairs there. Reading that book, I got more seriously into making mobiles.
My understanding of his mobiles has increased greatly nowadays.
Previously, there was a class of mobiles that he made where the parts did not have freedom to move in relationship to each other.
