Pierre-Simon Laplace, an exemplary French Mathematician, once quoted: “It is India that gave us the ingenious method of expressing all numbers by means of ten symbols, each symbol receiving a value of position as well as an absolute value; a profound and important idea which appears so simple to us now that we ignore its true merit.

I intentionally aimed to start this article with a quote by an excellent western mathematician, because we Indians need validation from westerners. We are quite capable of making high strides in science, technology, and innovation, but there is a lack of vision; lack of confidence.

The newly Independent India of 1947 had a vision: a vision to transform into a developed country using scientific interventions. We had some great revolutionaries who worked tirelessly to shape a bright future for our country. Dr. Vikaram Sarabhai founded the Indian Space Research Organization (ISRO) while Dr. Homi J Bhabha, the Department of Atomic Energy (DAE). There was a time when Dr Sarabhai convinced a Church to give land for a rocket launch station.

When India became Independent in 1947, people just wanted to earn enough to survive in the rapidly changing, bitter conditions. Today, when we are one of the economies of the world, we are fighting over temples and mosques, trying to rename cities, and dream of resurrecting some thousands of years old notion of India, the quest for scientific temperament is lost somewhere along the way.

Over the years, India’s spending on Research and Development has increased significantly in overall value but its share in GDP has remained stagnant at 0.6-0.9%. The research being done in India is quite good if we compare it to the funding received. However if we compare it with the developed countries, the gap is phenomenal.

India’s space program, atomic energy program, development of supercomputers, or development of light combat aircraft- Tejas shows that Indian scientists have given great results at a fraction of the costs of their western counterparts. Still the allocation of funds for the scientific research is well short of what is required to catapult India into the league of developed nations.

If we deep dive into the probable causes of underfunding of Indian scientific research in spite of giving good return on investment, it boils down to the lack of awareness about the same among the larger public as well as policymakers. As we know that the best way to receive funding is to create awareness about a valuable product. We don’t lack products; we lack dialogue. Science is hardly ever reported in India. It’s rarely a point of discourse. When there is no discourse around something, it leads to a lack of interest. This is also driving away the bright students from pure sciences to the technology and management which is more remunerative.  

Another issue that sprouts up from lack of discourse is the lack of belief in science. We have seen how in India, many public figures started spreading home remedies and terrible unchecked solutions like the benefits of Cow Urine during the COVID outbreak. The news channels, instead of discussing facts, talked about conspiracy theories. These news channels sometimes invited scientists for talks, but eventually, ruined everyone’s time for their TRP by asking them about the conspiracy theories.

Science literacy can reduce these pseudoscience tactics. Indians extensively believe in spirituality which is good for personal motivation and values, however the unscrupulous elements have often used it to spread misinformation and personal gains. It's imperative that we take a stand to promote scientific thought, and this is not at all an arduous task. Instead, the solution is straightforward: We need to communicate.

We need our own Neil DeGrasse Tysons, Carl Zimmers, Carl Sagans who can communicate with the common people about scientific development, in a simple language. This will help us to kick start our journey towards the Golden Era of Science without a baggage of baseless beliefs, pseudoscience, and untested products.

Plant- Microbial fuel cell: Generating electricity from green, living plants

Humans are capable of discovering and creating great things with the help of science and one such impressive discovery is that green, living plants can generate electricity. It may seem unbelievable, but not impossible.

One must be wondering how this technology works. Well, the answer is quite simple; photosynthesis. Plants excrete organic matter into the soil as a result of photosynthesis. Only some of the organic matter is used by plants and the rest is released in the soil. This released organic matter is broken down by bacteria. In the breakdown process, electrons are released as a waste product. Since the movement of electrons produces electricity, these electrons, which are of no use to the plant, can be harvested. The best part about this innovation is that the plants from which energy is being generated are not affected in any way.

This idea was first put into use by a Dutch start-up called Plant-e. This company was launched in September 2009 and is successful in launching and selling many environment- friendly products like DIY kits to the public for experimentation purposes and modular systems which could be easily installed on green roofs for abundant electricity production. Plant-e is involved in various projects, within The Netherlands, like automatic lighting systems in gardens and many more.

This technology works with the plants which thrive in moist soils and where the water is present in abundance. Therefore marshlands, paddy fields and deltas are some of the most suitable places for setting up plant batteries as a huge amount of water is present in those areas. Hence, the use of this technology is limited to certain geographic areas containing moist soils and cannot be used in arid regions. It may, however, promote the growth of more trees and plants which will gradually reverse the malicious effects of global warming.

Another obstacle in widespread adoption of this technology in today’s time is the high cost of installation of the system. The initial adopters of this technology are those who are attracted by the efficiency and eco-friendly nature of the plant batteries and willing to pay a premium for it.

The concept of plant batteries can be further taken into rural areas where most of the population still does not have access to adequate electricity. It is estimated that plant-MFC technology can cover upto 20% of European Union’s primary future electricity needs. Also, plants are almost 100% efficient at converting photons from sunlight into electrons which indicates a bright future for this technology. However, more research needs to be done in this field.

Another innovation in the field of green electricity is using algae , which often grows in ponds and rivers, for generating electricity. The basic concept which explains the working is similar to the way plants are able to produce electricity; photosynthesis.

Various other ventures in the field of renewable energy also include vegetable batteries, meaning, electric power generated from fruits and vegetables like lemons, tomatoes and potatoes, have been investigated. According to experiments, at least 3 to 4 vegetables are required just to light a small LED bulb. Moreover, it leads to poisoning of the vegetables and those food products need to be thrown away, without being useful for consumption purposes. It is therefore not a viable option for energy production.

Plant based electricity generation is still an evolving technology which has immense potential for producing energy in an environmentally sustainable way. It will realise full potential when the installation cost is attractive enough for the farmers to prefer it over the electricity grids or fossil fuel based personal electricity generator sets.
