There are nano-engineered designs, which at least have been analyzed theoretically, that show the potential to be very lightweight, very inexpensive, very efficient, and we'd be able to actually provide all of our energy needs in this renewable way.
ナノテクによるデザインなら 少なくとも理論上は 軽量性 経済性 効率性を 実現できる見込みがあり すべてのエネルギー需要を 再生可能なもので賄えます
