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.

Black Lives Matter: Looking back at the journey of racial justice movement as a Nobel Peace Prize Nominee

The killing of George Floyd by a police officer in the state of Minnesota, has confronted the people of the United States in particular and the Western World in general about the existence of deep-rooted racism which has remained even after the Civil Rights movement and many decades of progress.

The years of racial discrimination led to the emergence of the Black Lives Matter (often abbreviated as BLM) movement. The BLM movement has been nominated for the 2021 Nobel peace prize as well.

This article explains the BLM movement, it's nomination for the Nobel Peace Prize as well as its symbolics importance in the lives of the black people. In other words, it looks back at the journey of this racial justice movement as a Nobel Peace Prize Nominee.

What is the Black Lives Matter movement?

The BLM movement started in 2013 after George Zimmerman—a white man—shot dead—black teen—Trayvon Martin—to death in 2012. The term “Black Lives Matter” was taken from the tweet of a woman named Alicia Garza, which turned into a trending hashtag and later into the name of the whole movement, co-founded by herself, Patrisse Cullors, and Opal Tometi.

The movement aims at equality and racial justice for Black people and highlights the injustices and oppression against them.

Furthermore, there is also strong resistance from the police and usage of military weapons against the black protestors as compared to the white ones, a kind of systematic racism which was clearly visible during the Storming of the Capitol Hill.

When a black person named George Floyd was killed by a white police officer in Minnesota on 25 May last year, the movement gained momentum and there were solidarity protests not only in America, around the globe—including countries like the UK, France, Australia and Germany. There were even violent protests in some parts of the US, and in some places the right wing groups clashed with these protestors.

The Movement Growing Profusely

A pro-right wing ruling government, where the President himself was criticised for being racist on several occasions and the upcoming elections led to increasing dissent—furthering the growth of the movement. George Floyd became the face of the movement along with many other black people who lost their lives before due to systematic racism—some names in the unfortunately endless list were Breonna Taylor, Ahmaud Arbery, . The movement also started getting the support of Hollywood celebrities, who supported the movement on their social media handles.

Amidst of all this, a similar killing of yet another black person, named Jacob Blake happened, which sparked the protests further.

“The group has called for defunding the police for at least five years”, Black Lives Matter Los Angeles co-founder Melina Abdullah told CNN. Some of the protestors believe that defunding the police could decrease such incidents.

In June, after pressure from BLMLA and massive protests, the Los Angeles City council unanimously approved a measure to develop an unarmed model of crisis response that would replace police officers with community-based responders for nonviolent calls.

Corrine Basabe, a black woman, started the George Floyd Justice Billboard Committee. Because of that, there are also billboards in cities like Los Angeles, New York and Washington DC, which are made for people to see regarding the Black Lives Matter movement and the killing of George Floyd. This way, many people driving through the roads could be reminded of what happened.

Featuring an oil painting by New York City artist Donald Perlis, a white, the billboards also include a quote from the Rev. Martin Luther King Jr.: "Injustice anywhere is a threat to justice everywhere." His painting was also displayed in New York’s Times Square.

When asked what she hopes for BLM's future, co-founder Patrisse Cullors said she knows the movement will win. "I know this because our work is full of love, healing and dignity," she said. "And we centre Black people's humanity and life over our death and decimation."

Backlash

The movement faced backlash from various right-wing groups like The American Patriot and Proud Boys. There was a slogan “All Lives Matter” from the Anti-BLM protestors, which minimises the problems faced by the black community in their daily lives. The then President Donald Trump also refused to condemn the right-wing groups and he defended the police instead of supporting the Black people’s cause.

In Arizona, Rep. Walt Blackman, a Black GOP member of the Arizona Legislature labelled BLM as a “terrorist organisation” in an interview with Fox News Radio affiliate KFYI.

There are a lot of post-truth narratives defaming the BLM movement.

Nomination for Nobel Peace Prize

As mentioned earlier, the BLM movement has been nominated for the 2021 Nobel peace prize, for the way they spread and called for a systematic change in the world, through non-violent protests. It has been nominated by a Norwegian MP.

In his nomination papers, the Norwegian MP Petter Eide said the movement had forced countries outside the US to tackle racism within their own societies.

“I find that one of the key challenges we have seen in America, but also in Europe and Asia, is the kind of increasing conflict based on inequality,” Eide said. “Black Lives Matter has become a very important worldwide movement to fight racial injustice. They have had a tremendous achievement in raising global awareness and consciousness about racial injustice.”

He said that one other thing that impressed him about the BLM movement was the way “they have been able to mobilise people from all groups of society, not just African-Americans, not just oppressed people, it has been a broad movement, in a way which has been different from their predecessors.” He has previously nominated human rights activists from Russia and China for the prize.

His written nomination concludes: “Awarding the peace prize to Black Lives Matter, as the strongest global force against racial injustice, will send a powerful message that peace is founded on equality, solidarity and human rights, and that all countries must respect those basic principles.”

Nominations for the Nobel peace prize are accepted from any politician serving at a national level, and they are allowed only 2,000 words to state their reasons. This year’s deadline was February 1, and the committee prepares a shortlist by the end of March. The winner is chosen in October and the award ceremony is scheduled for 10 December. The World Food Programme was the winner last year.

The movement deserves the nomination, and if it is declared the winner of the Nobel Peace Prize, then it’s going to be a huge win for the Black people and will give a push towards an ideal where there will be no racism.
