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.
On olemas nano-projekteeritud kavandid, mida on vähemalt analüüsitud teoreetiliselt, mis on potentsiaalselt väga kerged, väga odavad, väga tõhusad, ja me suudaksime tegelikult täita kogu meie energiavajaduse sellisel taastuval teel.
