As an Asian guy, Algae being scummy seems a weird concept, it to me is like always been associated with Agaragar, a jello alternative common in asia and spirulina a superfood, and seaweed. Algae growing on roof giving electricity, with overgrown stuff being then removed, on a tap for a soup or jelly seems like a win win to me.

[@NothingXemnas]

I am also Asian, but my views are different. Algae in food is pretty common, but if I saw a lake covered to the brim with a green sludge, I wouldn't dare step into it. I also never saw algae washing ashore on local beaches, so I really only ever saw them in their habitat in unused pools and fishing ponds.

Excellent video, as always. Something that might be helpful to incorporate into your videos would be assigning a Technology Readiness Level score to whatever the topic is for each one. This is something that NASA does for assessing how far along a particular new technology is, and how close it is to being able to be fielded. Something like that would really be helpful for viewers to understand if the particular topic of a video is still something that's theoretical, been demonstrated in the lab, or is being scaled and ready for mass market deployment.

If you combine the cells with high lipid algae you may be able to make the photovoltic charge and filter off some algae for biodiesel using the same device. The challenge is keeping the bioreactor chemistry going without harming the photovoltic cell efficiency. This is probably not something the homeowner or small business would want to deal with, but an energy generation business that can power via solar cells during the day and via a biodiesel generator / turbine at night might be quite happy.

As a plant tissue culture scientist who's worked with plant cells in liquid culture to prep them for bioreactors, I could envision a system where the algea are slowly removed and new algea feed into the system along with any nutrient feed necessary. For energy efficient cooling, I'd consider a geothermal heat pump approach to help stabilize the temperature and (hopefully) prevent it from moving past min/max temps.

[@daniellapain1576]

I'm not a scientist but I was thinking along the same lines. Having a system that refreshes the algae while producing energy means that you could potentially have a solar panel system that exceeds the lifespan of traditional solar panels depending on the anode and cathode material. Waste algae can then be processed into biomass products such as fuel and fertilizer to run a generator at night and feed gardens. I would make the anode and cathodes replaceable. This tech could be extremely useful as a greenhouse technology.

[@nmatheis]

@@daniellapain1576 Correct, it would be similar to a continuous feed bioreactor and there are several ways to make it much more sustainable than conventional solar panels. The typical problem with bioreactor systems is contamination, so they'd need to solve for efficiency, synergy, sustainability, and sterility.

It seems like it would be worth testing a larger-scale circulatory system for the algae. A system set up with a working environment and, a resting environment, so that the stressing is only for an optimal amount of time, where the algae that has been producing for so long is swapped out with fresh, or freshly rested algae while the stuff that has been working for a certain number of days is allowed to rest and recuperate in a cooling pond, and maybe even reproduce. Like a spa day for algae. And then see how long the lifespan of the algae can be stretched collectively. It would be more like a natural organic system of operations for an organic-based substrate. After all, you get your best work out of your workers when you don't work your workers to death.

this seems like a great way to power an algae farm using the leaky electrons from the photosynthesis process that you're using to grow the algae in the first place. pump the algae through the PV panel using the power from the PV cell and allow it to grow (sure let's throw H2 production in there), when it's ready convert it into sustainable aviation fuel/shipping fuel/fertilizer/chemicals/etc. You could even make a tandem cell on the tank with a quantum dot cell tailored to absorb the wavelengths of light the algae doesn't use.

It typically burns up any electrical device used to step down the power. I don’t think direct energy capture with lightning is going to happen without exotic materials that might not exist. I could however see a potential of utilizing a lightning rod to divert the lightning into set of tungsten resistive heaters to store the energy as heat similar to all the plans to use such a device to store excess renewable energy as heat. Even then, it’s a very intermittent energy source that would make renewable look like nuclear by comparison.
