I am pretty sure that there will be people who disagree, but mosquitoes are by far the most irritating insects around. Of course this is the opinion of a person who has to only deal with the itchiness for a few days and then forget about the unpleasant experience. But many are not so lucky.
Every year, over a million people are killed by malaria and there is no effective method to tackle this problem. The only solution is to destroy mosquito breeding grounds and curb the problem at source. As mosquitoes breed in stagnant water, I concluded that surface aeration would the best means of eliminating breeding grounds. It would prevent a mosquito from laying eggs as it can lay eggs only if the water surface is completely still. And even if the mosquito does lay eggs, its larvae would suffocate as they need to remain on the water surface to breath. The device would also reduce the larvae’s source of nutrition as aeration hinders the development of algae, anaerobic bacteria and the surface microlayer.
So I built a solar-powered device that creates surface turbulence through aeration and thereby prevents mosquito breeding:
This device automatically switches on when it comes in contact with water so that it floats up and starts running when flood-water gets collected. It generates air bubbles that can effectively produce ripples up to a radius of 2 meters. The air pump is timer-based and runs at intervals of 10 minutes to increase the life of the device and maintain a balanced water oxygen level. I have also provided an alarm which alerts if the water body dries up or someone tries to remove the device from the water.
The world is spending billions of dollars for developing vaccines for vector-borne diseases like malaria. However, curbing the problem at source is a much direct and effective solution. At less than $10, this device is not only affordable for developing countries like India, but can be easily implemented at large-scale.
At present, there is no such sustainable product to reduce mosquito breeding in water bodies. If this device is improved upon and ubiquitously installed in villages and cities, then I’m sure the world will soon be free from mosquito borne diseases like malaria and Zika.
