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.

Persecution of Uighur Muslims in China and the silence of Muslim Countries

Uighur are natives of  Xinjiang province of China who are Muslims and regard themselves as culturally and ethnically close to Central Asian nations. Xinjiang province has been under the control of China since it was annexed in 1949 and many Uighurs still identify their homeland by its previous name, East Turkestan. There are around 11 million Uighurs in Xinjiang and China claims that Uighurs hold extremist views that are a threat to national security.

In 2017, the Xinjiang government passed a law prohibiting men from growing long beards and women from wearing veils and dozens of mosques were also demolished.

As per the report of UN Committee on the Elimination of Racial Descrimination, the Chinese government has detained at least one million Uighurs in the detention camps in Xinjiang, China. After denying the existence of the camps for a long time, when the photos of the camps emerged, the Chinese government called them “re-education centres'' for Uighurs though the former detainees said they were detained, interrogated and beaten because of their religion, and not “re-educated.”

In July 2019 to the U.N. Human Right Council, 22 countries, mainly European countries, responded to “disturbing reports of large scale arbitrary detentions of Uighurs” and condemned the Chinese leadership.

Four days later, 37 countries, defended China’s “remarkable achievements in the field of human rights” by protecting the country from “terrorism, separatism and religious extremism.” The list of the 37 countries also included Muslim-majority countries like Saudi Arabia, Pakistan, Egypt, Qatar etc.

At the end of October 2019, 23 countries including France, the United Kingdom, United States denounced the repression of the Uighurs at the UN Committee on Social, Humanitarian and Cultural Affairs. Nevertheless, Beijing won the support of 54 countries, who praised the Communist Party’s management of Xinjiang.

In February 2019, Saudi Arabia showed their “respect” for Xi Jinping, the Chinese leader before they signed major commercial contracts with China. Egypt wants Beijing to finance its infrastructure and hence allowed the Chinese police to interrogate Uighur exiles on its soil in 2017. Pakistan, who has talked about the mistreatment of Rohingyas, has been silent on Uighurs since the Chinese Belt and Road Initiative is going on in the country.

Even Iran, who issues occasional criticism wants support from China and hence keeps the criticism coded. “There is a lot of sympathy for the Uighurs in Turkey, but the reality is that Erdogan needs China as an ally for economic reasons and to counteract the West’s diplomatic pressure on issues like Syria,” said Rémi Castets, a political scientist.

In 2017, the Organisation of Islamic Cooperation responded very differently to the Rohingya Crisis (Myanmar’s military crackdown on the country’s Rohingyas), where countries like Saudi Arabia, Iran and Turkey defended the rights of the Muslim minority group in Myanmar and actively condemned the treatment of Rohingyas in the UN Human Rights Council in Geneva.  

The question here arises is that contrary to the sentiments of their citizens, why do Muslim states stay silent over China’s abuse of the Uighurs?

Sophie Richardson, the director of China at Human Rights Watch, has a short and simple answer — there is less solidarity for Uighur than Rohingyas or Palestinians because China has managed to win these countries’ support due to its economic might.

Only time will tell how long these countries will continue to give preference to the economic interests over the anti-China sentiments of the citizens.
