Via youtube is er een video
over toekomstige energiebronnen:
10 Future Energy Sources...en ik plaatste er volgende opmerking:
Q:
What about Deltaworks as in Holland
along coasts
to gain electricity from the tides
(and against sealevelrise)?
And as windmills aren't necessary
for electricity, to fill up the barrages?
Would'n that be some kind of "perpetuum?"
Eternal energy because of the tides?
Wat vinden jullie?
