It is indeed a proud moment when 3 students from India have entered the the finals of Google Science fair 2012. Here is the brief about who they are and what are their projects. Kudos to these young scientists!
Vertical Multi-Level Farming to Increase Crop Yields – An Affordable and Feasible Design
Sumit Singh, 14 years old, Lucknow, India
My design for a Vertical Multi-Level Farm is low-cost. It has been tested and I have proved its feasibility. It is affordable by small farmers who can use this method to increase crop yield in agriculture and horticulture.
Water-efficient toilet – The “Vacu-flush.”
Rohit Fenn, 16 years old, Bangalore, India
“Vacu-flush” is a redesign of the conventional toilets used in most homes now-a-days. It uses a partial-vacuum assisted flush to conserve over 50% of the overall water used in a toilet to flush out excrement.
Visible Light Deoxygenation
Raghavendra Ramachanderan, 17 years old, Bangalore, India
The project intends to develop a chemical reaction that converts an alcoholic substrates into their corresponding alkanes. The conversion is catalyzed by sunlight, and a few other reusable components. The reaction is absolutely ecofriendly and also near-quantitative yields have been obtained. A serious application of this work is in the re-conversion of partially oxidized fuel (alcohols) into usable fuel. This way, fuel can be used multiple times and energy can be obtained from it.
