  • With an energy conversion efficiency of usually 75 to 80 % they are really efficient and don’t have as much energy loss as other types of energy storage. It’s a simple, but powerful concept and I find it beautiful. However, there is some concern regarding their impact on the local ecosystem. Not only do they need huge water reservoirs, which are artificially created and therefore might impact nearby rivers and even fish migration, but the way they are sealed with concrete or asphalt also disallows the development of riparian vegetation. From an ecological perspective they are basically dead zones.

    Still, considering several alternatives, I think it’s one of the better options. Although it’s not cheap to build those, which is a problem in our current capitalitic society

    The Abrahamic religions do not have a monopoly on the concept of God.

    Yes. I just made few examples on popular concepts. And I can make similar examples for a lot of other concepts. However, to discuss this further, we need some clear definitions.

    Do the ridiculous things now ascribed to electricity […] prove that electricity doesn’t exist?

    This is a form or erroneous attribution. It reminds me of the luminiferous aether of which physicists thought for a long time that it exists until it was disproven. This is a testable hypothesis. Your pixies might even be testable to a certain degree. But beyond a certain point they aren’t. Therefore being in the realm of pseudoscience again.

    If we observe electricity, of course elctricity exists. But if we don’t know its cause, it’s important to investigate it. We have to investigate cause and effect instead of just assuming that a higher power plays a role. That’s our only way to gain knowledge and separate fantasy from reality.

    And currently, religions with their concepts of deities reside in the realm of fantasy.
