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.

The Toxicity in Video Games and Cyberpunk 2077

Cyberpunk 2077, the most awaited video game was released on consoles and PC on 10th of December, 2020. The game went under 10 years of build-up and had kept gamers waiting for over 8 years. Cyberpunk 2077 is inspired by a cult-favourite tabletop roleplaying game. The video game was designed by well-known Polish studio, CD Projekt Red. Cyberpunk was the studio’s first big console game since The Witcher 3: Wild hunt which was an extraordinarily triumphant game that won numerous awards after its launch in 2015.

The popular video game, when released, faced backlash from the gaming community and non-gamers for several reasons. To many observers and gamers, Cyberpunk 2077 even proved to be an absolute failure. Several gamers called out the game developers for the promotion of sexiest ideologies and transphobia. However, the reviews weren’t well received by the fans. Cyberpunk 2077 fans responded with unacceptable abuses, harrasing and hateful messages and even rape and death threats.

Keanu Reeves in Cyberpunk 2077

Cyberpunk 2077 released ample previews, trailers, motion pictures and marketing material. Aside from this, the appearence of popular Canadian actor, Keanu Reeves as a character in the game carved the expectations of gamers and promised a sexy and kinky world of futuristic and revolutionary action. CD Projekt Red, one of Europe’s most successful video game company announced Cyberpunk 2077 project in 2012 and released the first trailer in 2013

The game is set in an alternate timeline in the city of California. The streets in the game are owned by tyrannical corporations. Everyone in the game modifies their body with illegal technology. Much of the state in the video game setting is said to be suffering from the impacts of a major nuclear attack which happened years ago. Every player gets to be a cyber-enhanced human who has to fight against physical and psychological threats to their survival. The game character of Keanu Reeves comes in as your sidekick.

In 2018, the developers insisted and had assured the gamers that Cyberpunk 2077 would not include in game purchases. CD Projekt Red did not want to lock any content behind a paywall. The studio was also insistent that the game would come out only when it was completely “ready”. They announced that the release would take place in April 2020 but it was delayed multiple times due to the COVID-19 pandemic as well as other quality problems that the game was facing. When it was finally released in December 2020, gamers expected their experience of the game to be “worth the wait”. However, the video game wasn’t well revived by all. In spite of several months of work that went into making and developing the game, the game was launched with several technical issues. Players on both PC and consoles were having terrible experiences. As a result of multiple glitches and technical problems, the characters’ faces were obscured and the game would reset randomly. Some of the environments or areas of the game map was unappealing. The game even caused consoles to crash repeatedly and sometimes sacrificed players’ progress. One glitch led to characters’ breasts and penises being exposed. The characters’ genitals would poke out of their clothes. CD Projeckt Red offered refunds to players who were disappointed with the product. In fact, they updated a self-review discouraging gamers from playing the game on console until the game was fixed and improved.

Cyberpunk 2077 was roundly criticized by reviewers, game designers, industry insiders and other gamers across the gaming community. The wait and hype for the game had already created a fanbase which turned toxic by harassing reviewers who criticised the game.

There is another reason why the game wasn’t well received. Cyberpunk 2077 transphobia was apparent in the game contradicting the fact that the developers had claimed that the game was ahead of its time. The game has an incredibly detailed character creation menu. The players can control several aspects of their character’s appearance including the shapes and size of the genitals. The game even allows players to decline the option of including genitals to their characters. However, this isn’t the problem and is in fact appreciable. The idea of not determining gender by the character’s genitals in fact made many trans players happy. But this soon turned into disbelief and disappointment. The gamers realised that the game actually assigned the gender to the characters not based on their genitals but rather by the voice. Characters with higher-pitched voices were identified as females and characters with deep-voiced characters were assigned male pronouns. This purports the toxic idea that people’s gender can be determined by certain traits. A non-sexist video game would determine the gender of a player’s character based on an independent choice made by players themselves. This is uninfluenced by other physical traits or qualities.

Several reviewers called out Cyberpunk 2077 for promoting sexist ideologies. Unfortunately, toxic fans harassed the reviewers. “You just KNOW when you're going to get harassed. If the game with all the hype has anything wrong with it, and you're honest about that, or even just want to provide any context outside of ‘it's fun’, you're going to get harassed. It's a given.” These were precisely what Susan Arendt, a podcast host quoted. She even second guessed herself whether sharing her true opinions was worth the hateful, threatening and harassing messages that she received.

Controversial Tweet by Cyberpunk 2077 Twitter Handle

In the early days of arcade, gaming was a family activity. The popular male dominance and stereotype that only boys or men are good at video games were perpetuated in the past three decades. We observe this change due to sexualisation of video games. Today, most video games aren’t family friendly as they include explicit and sexual content. This, in fact, is a marketing tactic used by developers to target the male population. In 2018, a Cyberpunk 2077 fan who was awaiting the game at that point of time tweeted that the user wanted to see more from the “guys” at CDPR. In response to this tweet, CD Projekt Red tweeted, “Did you just assume their gender?!”. On the look of it, the tweet seems innocent but it is a joke at the expense of the trans community. After receiving backlash to the tweet, CDPR took it down and issued an apology staying sorry to “all those offended”. The apology seems like another targeted mockery and CDPR did no right by not taking responsibility for its actions.

Not only is Cyberpunk2077 transphobic and sexist, it is non user friendly as well. The game has several epilepsy triggers without any warnings about it. There are several instances and situations in the game where the effects and the graphics are brighter, louder and flashing. This is a general trigger for seizures. Liana Rupert, a player of Cyberpunk 2077 suffered a major seizure and at several moments felt that she was close to another one. After bringing this to the notice of CD Projekt Red, the company agreed to add trigger warnings wherever necessary.  

The gaming industry has definitely taken a few steps forward in terms of inclusivity of all genders but has also taken a few steps backward. While all genders are welcome, they still face harassment and judgement for simply existing in the community and need a lot more improvement.
