That’s part of why that move to coin that phrase was so powerful. There are real conspiracies/intelligence agency operations (like regime changes in several countries during the 20th century), and then there are completely idiotic ideas and takes (like flat earth) and ones that were never meant to be taken serious (like birds aren’t real).

That makes it really tedious to weed out the bullshit and distinguish it from the stuff that has substance.

I agree. Unfortunately that is too abstract a factor for most peoples present investment decisions.

Either the article is disingenuous or he’s an absolute idiot.

Or maybe you didn’t realize this was an analysis of the situation and an outlook on possible future development based on his economic expertise rather than a call to action.

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.

There’s just no economic incentive to do so. (yet?)

I once accidentaly shorted the connector cables of a battery pack with 4 AA batteries. It very quickly generated enough heat to set the insulation of the cable on fire.

Don’t underestimate short circuits!

That chart is a good starting point, but it doesn’t tell the whole story. It only shows the absorption spectrum for Chlorophyll A, which is a key pigment for photosynthesis in all plant species, but there is also Chlorophyll B, and there are numerous other so called accessory pigments (beta carotinoids are the most common examples), that can work in conjunction with chlorophyll in a photosystem to collect light of different wavelengths. Algae in particular show a greater diversity of accessory pigments. They have evolved use light at different depths below the water surface, where it reaches them with a different spectrum, because water itself absorbs part of it. Have a look at red algae and brown algae, for example.

So if you want to grow algae in a controlled environment, you should do some research about the particular absorption preferences of the species you’d like to grow.
