existentialism is an escape
One of my coworkers is occupied with a project that concerns mounting a number of windmills off the North Sea coast. Windmills on sea are different from the ones on land. They do not stand tall and slender like trees, instead they have sturdy crouched truss frames that give them a lot of balance and they are relatively much less high.
We had a strange discussion, because he told me that he does not believe that windmills are an efficient solution to the energy needs of the human race, he thinks we absolutely need nuclear, if we continue to produce babies like we do as a human race - to do him credit, he doesn't have kids and doesn't want them.
I told him that I am sure he is wrong. It felt funny to me that I - a freelancer temporarily employed in this company - was reassuring him about the value of his work, but I meant it. Wind and sun are much more powerful than we may realize and to harness them is absolutely profitable. My mother had 16m2 of solar panels on her roof and every year the electric company gave her trouble over the annual bill, they just could not believe that she produced more electricity than she consumed and they even accused her of fraud. She sent them photos of her roof and the solar installation, but they told her "solar panels will only reduce your energy bill somewhat, it is impossible that they produce all your annual electricity". From the mouth of the "experts"!
One day, to her immense relief (sort of), the solar panels were struck by lightning, and the problem was solved. But.. after two years, she has regained her courage and she is almost ready to try again...
