  • There doesn’t need to be any knowledge involved. It happens, because it works. Neither the beetle nor evolution itself “know” anything about quantum physics. The beetle is just a beetle and evolution is not even an entity that has any agency, it’s just a process that’s happening and that leads to remarkable results over time.

    This is just one more example for the old discussion how complexity can develop through evolution. The classic example is the eye of vertebrates. Read up on that, if you’re interested in that discussion.

    Don’t worry. Asbestos cement is not really dangerous, as long as the concrete is intact and you don’t touch it, there’s nothing to be afraid of.

    It’s when it crumbles or you work on it, that you have to take care. The problem is Asbestos dust entering your lungs, where it’s very carcinogenic.

    But intact walls and roof are okay.










  • Maybe we’ll get to the point. This news just shows us, that solar power can really be very impactful, even in not-so-sunny Germany. And that we’ve reached a turning point, where we can no longer ‘just’ put up more solar panels, but also start developping systems to store this excess energy in an economically feasible manner.

    But actually, that’s nothing very new either. At least for home owners, who just put solar panels on their roofs, also investing in battery storage to use most of the produced energy themselves has been the economic strategy for a few years, since the price gap between what you got for putting energy into the grid, and what you had to pay for taking energy out of the grid was the only thing left that (economically) incentivized people to install solar power ever since the so called “Einspeisevergütung” subsidies have been dropped.
