A captura direta de ar realmente consegue remover o dióxido de carbono? | Anthony Taylor | TEDxKings College School

A captura direta de ar é uma tecnologia proposta para remover o dióxido de carbono da atmosfera depois de ter sido liberado. A palestra avalia a viabilidade dessa técnica, analisando os custos energéticos impostos pela química envolvida e quem arcaria com a tecnologia em grande escala. O palestrante, aluno do ensino médio na King's College School, em Wimbledon, chega a uma conclusão equilibrada, nem negativa nem otimista. O vídeo é do TEDx Talks.

• Remoção do CO2 do ar após sua liberação
• Custos energéticos da química envolvida
• Quem pagaria pela tecnologia em grande escala

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
