Dev Unawatuna

Dev Unawatuna is taking a year after A levels to work on improving his grades


Im an 18 year old trying to make the most out of life. I enjoy travelling and hope to see most of the world before I die. My other hobbies include playing sports such as football and swimming, forex trading and art. I love cars and motorcycles and like learning about and seeing how they are built and the history behind different vehicle companies. I am eager to learn new things and make new friends.

I am currently studying Maths, Physics and Accounting and hope to read mechanical engineering at university in 2020.

Energy from Outer Space

11 November 2019

Although Earth does have some renewable energy sources at its disposal, they are not efficient enough to help its ever growing population sustain. This will eventually lead to the energy sources we are exhausting now such as fossil fuels to run out and at this point it will be too late to rely on renewable sources. An energy crisis would lead to wars breaking out between nations as well as many countries who were once wealthy becoming poor. The only way to avoid this is to convert all sources of energy to renewable sources which would take a long period of time as well as taking up lot of resources and even then, the amount of energy produces is hardly enough. This leaves humanity with one other option which is to get energy from outer space. After doing some research i found a few ways in which we can get sustainable energy from outer space which are stated below.

Wind power converts the kinetic energy in wind to generate electricity or mechanical power. This is done by using a large wind turbine usually consisting of propellers; the turbine can be connected to a generator to generate electricity, or the wind used as mechanical power to perform tasks such as pumping water or grinding grain. As the wind passes the turbines it moves the blades, which spins the shaft. There are currently two different kinds of wind turbines in use, the Horizontal Axis Wind Turbines (HAWT) or the Vertical Axis Wind Turbines (VAWT). HAWT are the most common wind turbines, displaying the propeller or 'fan-style' blades, and VAWT are usually in an 'egg-beater' style. These turbines can be left on other planets such as Mars with windy climates where they will collect energy into large batteries which are then sent back to Earth using rockets and used up. This is a very expensive operation however with a high margin for error since a lot of things can go wrong. The turbines will also need a lot of maintenance as the weather on the foreign planet could cause damage to them. Since planets like Mars have constant weather patterns unlike Earth which has a constantly changing weather pattern for different regions, the wind turbines should be able to produce a lot of energy easily.

Space Solar Power gathers energy from sunlight in space and transmits it wirelessly to Earth. The solar energy available in space is literally billions of times greater than what we get today on Earth and since the lifetime of the Sun is an estimated to be 4-5 billion years, this makes space solar power a long-term energy solution that has high reward with low risk. As Earth receives only a small part in the 2.3 billion of the Sun's output energy, space solar power is by far the largest potential energy source available that also has the least impact on the environment. Solar energy is already used on nearly all spacecraft today and when made to work in a large scale should be able to collect solar energy that can then be sent to Earth.

Unlike nuclear fission, which splits an atom's nucleus in half causing the release of energy, nuclear fusion combines nuclei to produce energy. While nuclear fusion has already been tested with the hydrogen isotopes deuterium and tritium, those reactions give off the majority of their energy as radioactive neutrons, which raise concerns in both safety and production since radioactive waste is produced and the procedure is unstable and can lead to lots of problems. Helium-3, on the other hand, is very safe and it does not give off any pollution or radioactive waste. An isotope of the element helium, helium-3 when it's heated to very high temperatures and combined with deuterium, the reaction releases large amounts of energy. Just one kilogram of helium-3 combined with 0.67 kilograms of deuterium produces 19 megawatt-years of energy. There isn't much helium-3 found on Earth however a lot of it can be found on the moon. Scientists estimate our moon contains more than 1 million tons of helium-3. The energy stored in that much helium-3 is 10 times the amount of energy you'd find in all the fossil fuels on Earth.

North Korea

4 September 2019

The other day I was scrolling through YouTube which recommended the video "My life in North Korea vs South Korea" by the Youtuber Jacob Laukaitis. The video was around 16 minutes and had 13 million views, and showed the two very different worlds of people living on either of side of the border only a few miles from each other. Jacob describes what is happening in each clip and the things he learned.

He had booked a tour of North Korea where he would catch a plane from China and then travel around North Korea for a week. Jacob said that he was instructed to always listen the tour instructors and there was one rule that the tourist must always follow, that being that you cannot go walking around by yourself. This rule meant that the tourists had their freedom taken away and this surprised me a lot since in this day and age almost all people have the freedom to venture where they want to. Jacob also stated how the North Korean citizens never interacted with the tourists and tried their best not to stare. I assume this is because they fear they would be punished. Bearing this in mind something weird that happened near the end of the tour where a surprise was made for the tourist, where they could talk and dance with local citizens in their local park. Jacob stated how unusual this was since throughout the tour, none of citizens chose to interact with them and came to the conclusion that this was a set up event made to make the citizens look happy to the outside world.

In North Korea the leaders are considered to be gods by the citizens and this idea alone can be considered crazy showing just how isolated North Korea is from the rest of the world since no other nation has this view on its leaders. There are public holidays in North Korea where they celebrate their leaders. On these days people don't need to attend work but must go to a statue of their leaders and pay their respects. If it is noticed that you have not done this it can be assumed that you will be heavily punished since that is how important and loved North Koreas leaders are. North Korea is so isolated from the rest of the world that an North Korean that escaped to South Korea told Jacob that back when he was in North Korea they would watch pirated American films and say that the sky scrapers are fake and could not possibly exist. North Korea has lasted this long although being hated by most nations because it has China as an ally. China sends resources and money to North Korea allowing the dictatorship to get richer. The nations other sources of income come from allowing drugs to travel through the country as well as allowing other illegal activities to be carried out on North Korean soil.
