[고2] 2025 09월 – 23번: 우주 태양광 발전의 비효율성과 비경제성

 

It's conceivable that in a world where solar panels are incredibly expensive and there's an extreme collapse in the cost of launching objects to space, you might want to maximize your energy per panel by putting them above the atmosphere. But panels are cheap, and even if we assume pretty steep drops in the cost of space launch, the numbers don't add up. This becomes especially clear when you start to think about maintenance. Try to imagine acres upon acres of glass panels in space, regularly hit by intense radiation and bits of space debris while enduring the extreme heat of constant sunlight. They'll have to be repaired and cared for either by astronauts or an army of advanced robots. Solar panels in Australia can be cleaned by a teenager with a spray bottle and a cloth.

	내용	원문
가정	태양광 패널이 매우 비싸고 발사 비용이 극적으로 낮다면 우주에 설치하는 것이 고려될 수 있다	It's conceivable that in a world where solar panels are incredibly expensive and there's an extreme collapse in the cost of launching objects to space, you might want to maximize your energy per panel by putting them above the atmosphere.
반박	하지만 패널은 이미 저렴하고, 발사 비용이 크게 줄어도 경제성이 맞지 않는다	But panels are cheap, and even if we assume pretty steep drops in the cost of space launch, the numbers don't add up.
근거	유지·보수를 고려하면 문제는 더 분명해진다. 우주에서는 방사선, 우주 파편, 극한의 열에 지속적으로 노출된다	This becomes especially clear when you start to think about maintenance. Try to imagine acres upon acres of glass panels in space, regularly hit by intense radiation and bits of space debris while enduring the extreme heat of constant sunlight.
근거	결국 우주에서는 우주비행사나 로봇이 수리해야 하지만, 지상에서는 간단히 청소할 수 있다	They'll have to be repaired and cared for either by astronauts or an army of advanced robots. Solar panels in Australia can be cleaned by a teenager with a spray bottle and a cloth.
