Humanoid Robot Sophia

Short Summary 
KATHMANDU, March 22 - When Sophia, a social humanoid robot and the world's first robot citizen, greeted the audience at a conference in Kathmandu with "Namaste Nepal," the hall burst into applause of awe and appreciation.

The robot, who is championing the United Nations Sustainable Development Goals in Asia-Pacific, with a focus on innovation, was in Nepal Wednesday to attend the Innovation Conference and Fair: "Technology of Public Services and Development" organised by the United Nations Development Programme.

Dressed in a white UNDP logoed T-shirt, the two-and-a-half-year-old, red-lipped robot said that technology provides endless possibilities and opportunities for the world.

Highlighting the importance of technology in Nepal and its applicability to government models, Sophia said it can transform state institutions and help in meeting global sustainable development goals.

The celebrity robot, a "Citizen" of Saudi Arabia, added that technology and artificial intelligence can help in ending poverty and fighting starvation, corruption and ensuring gender equality.

English 9 95 In a question about humans fearing a robot takeover, Sophia joked citing it as fake news, although mentioned that she could be the first non-human to climb Mount Everest, which saw the entire hall erupt with laughter.

The one-day conference also featured an "Innovation fair" showcasing separate stalls with fresh innovations from youth, tech groups, NGOs and private sector participants, but Sophia was certainly the main attraction.

Reading II
Do you agree with these statements? Discuss.
Renewable energy could reduce emissions but also create jobs and improve public health.
Answer - Renewable energy sources are those sources of energy that never get depleted, for example, the energy produced from wind and water. Such energy reduces the need for fossil fuel power generation. They also help to keep the environment clean. This helps to keep human beings free from health-related issues. When people are healthy, they can have better job opportunities and focus on their work. 



The potential of renewable energy is immense
Answer - Non-renewable energy sources, such as coal, petrol, diesel, etc. are limited and can finish in a certain time in future. However, non renewable sources of energy last forever. The potential of renewable energy is immense. For example, every megawatt (MW) of wind energy installed creates up to 20 jobs; a single 1.5 MW turbine can reduce CO2 emissions by over 3,000 tons every year. And, technological advances have increased the efficiency and productivity of renewable energy. In the wind industry, for example, improvement in technology have made wind turbines 100 times more powerful compared to designs from the 1980s. Thus, we can say that the potential of renewable energy is immense.





The Alternative Energy Sources

Short Summary
All the Earth's oil deposits will dry up, and we'll be completely dependent upon alternative sources of energy.

The panels could convert that solar power into microwaves that continuously beam down to power-receiving stations on Earth, ensuring no energy is lost.

Idea II Many experts believe the simplest way of generating renewable energy is through our own bodies.

To harness the energy we generate through our own movement, we would simply need to wear a system that collects and converts it.

Idea III Wave energy is technically a form of stored wind energy, since waves are English 9 101 produced from winds which blow over the sea.

Wave energy is measured in kilowatts per metre of coastline; the US coastline has a wave energy potential of about 252 billion kWh per year.

These turbines produce double the energy of similar sized tower-mounted turbines.

Status Altaeros Energies has developed the first commercial airborne wind turbine called Buoyant Air Turbine, a circular, 35-foot-long inflatable shell, made of heavy-duty fabric.

Idea VI Fusion is the same process that powers the Sun, and has potential to provide a nearly inexhaustible supply of energy.

D. Answer the following questions.
a. How did JAXA prove the viability for the idea of space-based solar energy?
Answer - JAXA proved the viability of the idea of space-based solar energy by successfully converting 1.8 kilowatts of electricity into microwaves, after which they wirelessly beamed them a distance of 50 meters.


b. What do we need to generate energy through our body movement?
Answer - In order to generate energy through our body movement we simply need to wear a system that collects and converts the energy generated through our body movement.


c. In what way are Idea III and V similar?
Answer - Ideas III and IV are similar because both ideas emphasize on the conversion of one form of energy into another form. 


d. How can hydrogen be used as a source of energy?
Answer - We can use hydrogen as a source of energy by separating it from other elements. This gas yields high energy with no urity.


e. Why do floating turbines seem more effective than tower-mounted turbines?
Answer - 
Floating turbines seem more effective than tower-mount turbines because floating turbines produced double the energy as tower-mounted turbines.


f. Why is the fusion process environmentally friendly?
Answer - 
We can say that the fusion process is environment-friendly because it emits no pollutants or greenhouse gases and has no threat of nuclear meltdown.


g. What does ITER stand for?
Answer - 
ITER stands for International Thermonuclear Experimental Reactor.



E. Can you think of any other alternative energy sources? Talk about your ideas with your friends.
Answer - Looking at the scenario of my area, the most relevant and viable form of alternative energy sources would be bioenergy. We can generate bioenergy from organic materials known as biomass biofuels. Some examples would be recently living animal or plant byproducts and wood. For example, methane can be captured from landfills to produce bioenergy, which we then can use to produce electricity and heat. As an agricultural country, Nepal has a huge potential to generate bioenergy. In rural areas, people rear animals and they have agricultural residue in order to produce energy. In urban areas, a lot of waste gets produced and from this waste, we can separate organic waste and produce an adequate amount of energy from such waste. So, one alternative energy source that I think of is bioenergy.

Writing II
Write a news article about Green Energy. Use the following prompts.
Answer - Green energy is the type of energy that is generated from a natural source such as sunlight, wind or water. It often comes from renewable energy sources although there are some differences between renewable and green| energy. Renewable energy is the generation of energy from infinite sources but can negatively impact the environment. However, green energy is renewable energy that does not produce carbon emissions or negatively impact the environment. 
Green energy is perpetual in nature and it never comes to an end. Green energy is the most advantageous source of energy as it doesn't impact the environment negatively at all. However, the economic production and consumption of green energy is a challenging task. Though the developed countries in the present world have made good progress in the production and consumption of green energy, it is a very challenging task for developing countries such as Nepal regarding the production and consumption of green energy.
