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.

Iran, Turkey, Qatar Alliance: Will this mark a shift in MENA's Balance of power?

Qatar, Iran and Turkey have been forming an alliance—which impacts several countries—especially in the MENA (Middle East and North Africa) region. The move comes after Israel recently established its diplomatic relations with four Arab league countries, namely, United Arab Emirates (UAE), Bahrain, Morocco and Sudan. The article covers how this move can have an impact on the balance of power in the region.

Support for the Palestinian Cause

The three countries are critical of the Israel-Arab ties and support the Palestinian cause. Various Palestinian factions, including Hamas and Fatah as well, are shoring up ties with Turkey and other countries in the region that stand against normalization with Israel.

During his speech in the 75th United Nations General Assembly, Erdogan called out on Israel and proclaimed, “The occupation of Palestine is a bleeding wound.”

Since the Gaza attack, which killed 10 Turkish social activists aboard a ship by the Israeli commandos in international waters, the relationship between the two has only soured. After this incident, Turkey recalled its ambassador from Israel, downgrading the diplomatic status. Yet in 2016—after a few meetings—the relationship was restored. However, after another attack in Gaza in 2018, Turkey called back its ambassadors again and expelled the Israeli ambassador to Turkey. Since then they do not have full diplomatic status.

Following the attacks Erdogan—the president of Turkey—even called Israeli PM Benjamin Netanyahu “a terrorist.” The country has been openly supportive of the Palestinian cause, and has also sent aid for humanitarian relief to the Palestinians. Several Hamas leaders have been visiting, taking refuge, and even meeting with Erdogan.

On August 22, 2020, Hamas leader Ismail Haniyeh met Erdogan in Istanbul. Jibril Rajoub, secretary of Fatah’s Central Committee, as well arrived in Turkey on September 21, 2020 to meet with Haniyeh and his deputy Saleh al-Arouri and discuss ways to end the internal Palestinian division.

On the same day, Palestinian President Mahmoud Abbas phoned Erdogan and thanked him for his support for the Palestinian cause. The two have shared several calls since—discussing political developments and US pressure on the region to normalize ties with Israel and ways to face such pressure.

Turkey has tried to balance its relations with both Saudi Arabia and Iran, who happen to be arch rivals. But after the recent growing closeness with two of Saudi Arabia’s rival countries, Iran and Qatar, Turkey might end up straining its relations with Saudi Arabia.

Qatar-Saudi Arabia conflict

This diplomatic conflict is also known as the Second Arab Cold War (the first one being the Iran-Saudi Arabia Cold War). There is an ongoing struggle between the two countries to gain influence in the Gulf. Their relations strained especially after the emergence of Arab Spring. During that time, Qatar became in favour of the revolutionary wave, whereas Saudi Arabia was against it. Both the States are allies of the United States, but have a tussle in their ideologies. Both have avoided direct conflict with each other.

There are other issues between them which leads to further tussle-

1. Qatar broadcasts a news channel, Al Jazeera, which favours the Arab Spring.

2. Qatar has good relations with Iran, Saudi Arabia's rival.

3. Qatar also allegedly supported Muslim Brotherhood in the past. Which it denies.

The Qatar diplomatic crisis became worse in 2017. Saudi Arabia, the UAE, Bahrain and Egypt severed diplomatic relations and trade ties with Doha, and imposed a sea, land and air blockade on Qatar, claiming it supported “terrorism” and was too close to Iran. Yemen, the Maldives and Libya's eastern-based government also followed later. Qatar rejected the claims and said there was “no legitimate justification” for the severance of the relations.

How does this new alliance affect the other countries in the region?

The new alliance seems to lead into formations of two alliance groups or blocs in the region, with some countries siding with Iran, Qatar and Turkey and others with the Saudis and their allies. Another point to keep in mind is that Saudi Arabia is supported by the US, while two countries from the former alliance—Turkey and Iran—are supported by Russia. This will lead to further division among the Middle Eastern countries.

This alliance can also affect the trade among these countries, and can severe the ties of many Middle Eastern countries. The biggest beneficiary is going to be Israel, which doesn’t have good relations with most of the Muslim world, except the ones which established diplomatic ties recently by signing the Abraham Accords.

In North Africa countries like Egypt and Morocco recognise Israel. However, most of the North African countries also supported the Arab Springs, which is against the ideas of Saudi Arabia. The Islamic holy land seriously seems to have less Arab allies when it comes to opposing the Arab Springs.

In fact, there can be impacts on trade and diplomatic ties with other countries outside the Middle East and North African region as well. Countries will have to balance their relations with both these groups.

How does it affect the Balance of power in the region?

In international relations, balance of power refers to the posture and policy of a nation or group of nations protecting itself against another nation or group of nations by matching its power with the power of the other side.

There has been a Cold War situation between Iran and Saudi Arabia as they are very (perhaps most) influential powers in the region. But Saudi Arabia is still more influential as a business as well as a soft power—it has a richer economy, oil exports, and most importantly, being the holy land where every Muslim comes for Hajj pilgrimage—it has Mecca and Medina. It is the land where the Prophet Muhammad first delivered his messages and teachings. Iran may try to compete in the economic part, but isn't equally as challenging in the religious part—although it is an important country for the Shia Muslims.

There have been arms embargo on Iran by the UN for arms race. Russia and China have been eager to supply Iran with advanced jets, tanks and missiles, which is quite alarming for its Gulf Arab neighbours, especially its primary adversaries like Saudi Arabia and the UAE.

On 14 September 2019, drones were used to attack the state-owned Saudi Aramco oil processing facilities at Abqaiq and Khurais in eastern Saudi Arabia. The Houthi movement in Yemen claimed responsibility, joining it to events surrounding the Saudi Arabian intervention in the Yemeni Civil War and stating that they used ten drones in the attack from Yemen. Saudi Arabian officials said that many more drones and cruise missiles were used for the attack and these originated from the north and east, and that they were of Iranian manufacture. The United States and Saudi Arabia have stated that Iran was behind the attack while France, Germany, and the United Kingdom jointly stated Iran bears responsibility for it. Iran has denied any involvement. The situation has only exacerbated the Persian Gulf crisis.

By forming this new alliance, supporting the Palestinian cause—with Qatar—even supporting the idea of Arab Springs; the Iran-Turkey-Qatar alliance has a new power with them. What remains to be seen is the other Middle Eastern country’s decision—whether they support this new alliance and the Palestinian cause or go for yet another fragile “peace-building” initiative in the already disturbed region.
