I came across an article online about "Artificial Sun" and would like to share it here. The article states we are facing a big issue called "Energy problem". The population all over the world will reach up to 10 billion in 2050 and we need new power resource which is over 40 trillion KWh. The amount of world power generation in 2019 was about 27 trillion. So, that means we need as much other power resource as the whole earth. In terms of power amount, cost, eco-friendly and safe, hydroelectric power generation and solar power are not enough and are not reality. One of the solutions to this issue is nuclear fusion generation which attracts a lot of attention these days. It is said that nuclear fusion generation is to make artificial sun on the earth. The attempt is that we artificially create the same nuclear fusion reaction as one which generates inside Sun and extract the energy out of it. The fuel for nuclear fusion is heavy hydrogen and tritium. We can get them out of sea and they are called "inexhaustible energy source". In theory, one kiro gram(kg) can generate as much energy as 10 million kg fossil fuel. Now, the generation has a bunch of technical challenging, but Korea has cutting-edge technology on this and it has stayed ahead of the game. Anyway, the technology is expected to be commercialized in 2040 or 2050. I will turn 85 around that time and I really hope the commercialization is a lot faster and is affordable for everyone.

We might as well open it up and give it a try. This my friends called a slow cooker, Or also known as a Crock-Pot. They're sleeping shoes. The nine-tailed fox fairy has appeared in the world, And has got that benighted ruler So befundled he'll be: banishing his son and divorcing his wife, before you know it. They have passed the qualified teacher status skills tests in numeracy and literacy and ICT. those awarded qualified teacher status must demonstrate all of the following. They set challenging teaching and learning objectives which are relevant to all pupils in their classes. they base these on their knowledge of: the pupils evidence of their past and current achievement the expected standard for pupils of the relevant age range the range and content of work relevant to pupils in that age range. They use these teaching and learning objectives to plan lessons, and sequences of lessons, showing how they will assess pupils’ learning.
