So I thought of an idea -- what if we collect the sun with a large reflector -- like I had been thinking about way back when, when I was in high school -- but maybe with modern technology we could make a cheaper, large collector, concentrate it to a small converter, and then the conversion device wouldn't have to be as expensive, because it's much smaller, rather than solar cells,
そこで得たアイデアは 高校時代に考えていたような 大きな反射板で 太陽光線を集められたらどうだろうということです 最近の技術でもっと安く 大きな集光器を作り 小さな変換器に光を集められます そうすれば変換器はさほど高くならないでしょう というのは 太陽エネルギーを受け取る全受光面を
