直接空気回収で本当に二酸化炭素を除去できるのか？ | Anthony Taylor | TEDxKings College School

直接空気回収は、排出された二酸化炭素を大気中から除去することを目指す技術として提案されています。講演では、化学反応に伴うエネルギーコストと、大規模に導入した場合に誰が費用を負担するのかという点から、その実現可能性を検討しています。話し手は、ウィンブルドンのKing's College Schoolでシックスフォームに在籍する生徒で、否定的でも楽観的でもない慎重な結論を示しています。動画の提供元はTEDx Talksです。

Direct Air Capture proposes to remove carbon dioxide from the atmosphere after it has been released. Anthony assesses how realistic this is, working through the energy costs the chemistry imposes and the question of who would pay for the technology at scale. His conclusion is measured rather than either dismissive or optimistic. Anthony is a sixth form pupil at King's College School, Wimbledon. He is studying the International Baccalaureate, taking Mathematics, Physics, and Chemistry at higher level. He hopes to study Engineering at university and was recently awarded an Arkwright Engineering Scholarship, sponsored by the Royal Air Force. He is also a keen sportsman, with a passion for rugby and rock climbing, and enjoys volunteering with his local Scout group. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
