Firstly, who are tutors? Tutor is a hybrid profession combined from psychologist and classical teacher. Tutors support students to develop their abilities and master their skills, to find out personal interests and evaluate strong sides. Based on personal information, tutors create a detailed educational plan of studies and personal development for each of their students and control them through the whole educational process. Technology works like that: experienced and prominent professors teach their numerous students through the internet while in the regional classes tutors control, support students with practical tasks, and motivate them.

As it is known, tutoring itself is a quiet ancient profession. According to Wikipedia, it was originated in ancient Greece. So, why it became a rapidly developing trend in modern society?

Firstly, dual-teaching system or two teacher model in other words (which represents tutoring) can help community to overcome the distance gap. Experienced teachers and lecturers usually live in huge or middle-sized cities, which makes competition between students unfair as the quality of studies in small cities or villages is poorer. With the help of dual-teaching system, all students have access to the high-quality information.

Secondly, this method of studying can support society in terms of coronavirus. There is no need to gather 1000 students in one class with the help of co-teaching model: it might be dangerous for them as well as for professor as he or she is more likely to be in the most vulnerable, high age group. When it comes to the quality of such lectures, it will not fall dramatically because huge audience will be divided into smaller groups supervised and supported by tutors.

Thirdly, it will create ability to learn from the best in their fields cheaper. The knowledge and time of the most prominent people in the sphere cannot be cheap. As well as a person do not need to be a genius to explain students that 2+2=4. Two teacher model creates a unique possibility when tutors can answer simple questions or help students to solve simple tasks. When tutor is not able to answer the question or question is tricky, he will deliver it to the professor. As the output, the number of questions that professor should answer will decrease and he or she will be able to answer more interesting questions at the same time period.

As it is presented, co-teaching system is a nice technology which destroys distance gab, saves money of students and their parents, and makes our world safer place at the same time.

The problem of food losses is widely presented all over the world. According to research of independent analytical center TIAR, the worldwide production of food is 3,9 billion tons, while global food waste is 1,3 billion tons. According to same research, each 1 million ton of saved food is a possibility to supply 1,3 million people who are needed in it, ability to decrease emissions of methane in the atmosphere by 143 thousand tones and gain almost 1-billion-euro profits by selling nearly expiring products. As it is presented, problem is worth dealing with, optimization and decrease of food waste can bring immense advantages and possibility to achieve sustainable development goals. Food sharing can become a tool of reasonable distribution food between people as well as possibility to decrease amount of food waste by 30% and solve some environmental problems.

So, there are some ways how technology can help society to achieve aimed goals in that sphere.

Firstly, development of services which are aimed to decrease market inefficiencies. The example of it is a Japan food-sharing app called Tabete which was launched in Tokyo in 2018. Via this service you can cheaply by products which are close to be discarded or made of surplus ingredients which are left. The mission of a service is “to make everyone happy by making it user-friendly, shop-friendly, and environment-friendly”. This app works with nearly 600 restaurants, cafes, and bakeries. This service enabled people to support their favorite companies during pandemic and decrease losses connected with lack of tourists.

Secondly, cooperation of services with supermarkets and shops. For example, collaboration of German services foodsharing.de and lebensmittelretten.de enabled people to share food with each other and cooperate with supermarkets and shops. The collaboration was successful as the number of users increased in 4 times after that.

Thirdly, creation of user-friendly app. For example, British service Olio with nearly 2,3 million users helps people to share food as well as other goods. This app has a huge number of features such as own ecosystem, user-friendly interface and cooperation with many producers made it the most popular food sharing platform in US and UK.

Fourthly, spread the ideas of food sharing and reasonable consumption via educational and entertaining content. For example, Spanish food sharing service Yonodesperdicio created in 2015 provides users with online webinars, educational videos and masterclasses related to the topic. They also actively take part in popularizing ideas of food sharing at schools. The Awareness Officer, Laure Martos, is convinced that lack of knowledge of people towards this problem is the main target for the company to fight with: “citizens are not aware of the environmental, economic and social impact that food waste generates. Raising awareness of this issue will contribute to responsible and conscious decisions.”

According to Sharecity, a project which is aimed to find out sustainable potential referred to food sharing withing cities, Top three cities with active food sharing projects are Melbourne (149 projects), New-York (164 projects) and London (180 projects).

Food sharing service “TABETE” in Japan

Reading Time: 2 minutesStartup ZeroAvia is located in California and produce hydrogen-electric engines for planes. These engines are created to cut down the emissions of CO2 and, subsequently, pollution. Moreover, their technology enables powertrain to decrease maintenance costs and fuel costs by 75% and as output to reduce costs of the flight by 50%. Company has already conducted first hydrogen-electric passenger flight on their aircraft Piper-M class in research lab in England. The plane performed all necessary elements such as take-off, landing and others. This successful test also made Piper-M class the biggest commercial hydrogen plane in the world by now. Founder and CEO of a company, Valery Miftakhov, says that 10 airlines are going to use technologies created by ZeroAvia. Furthermore, British Airways airline claimed that they are going to cooperate with ZeroAvia in order to explore possibilities to make British Airways company more environmentally friendly, sustainable and boost switch to hydrogen-powered planes. As they mentioned on their website “ZeroAvia recently completed the world’s first hydrogen fuel cell powered flight of a commercial-grade aircraft as it aims to accelerate the world’s transition to sustainable aviation”. British Airways believe that technology of hydrogenelectric engines can become extremely important in the sustainable flights industry and will make it possible to avoid fossil fuels in this segment.

 

 

 

ZeroAvia claims that aviation brings over 12% of total transportation emissions and is going to exceed 1 gigaton of CO2 emissions this year. It also states that short flight (under 1000 miles) segment is the most dangerous in terms of carbon dioxide pollution and the company is going to solve this problem as fast as possible. The main mission of the company is to “Accelerate the World’s Transition to Sustainable Aviation”.

According to Bloomberg, company received foundation of 16,3 million dollars by British government for creation of a 19-seat plane with ability for a 500 miles flight and hydrogen-electric engine by 2023

Company also received 21,4 million dollars from Amazon Climate Pledge Fund (financed by Jeff Bezos), Breakthrough Energy Ventures (financed by Bill Gates), Ecosystem Integrity Fund, Shell Ventures, Horizons Ventures and Summa Equity.
