We already eat various forms of algae. Some are quite nutritious, some give us tummy troubles, some at excellent sinks for CO2. I'm very curious if we could mass manufacture something like algae and then pyrolize it to get fuel and solid carbon to sequester. If we find some good ideas for kelp, there's whole coastlines whose kelp forests have been decimated. We could start propagating and sustainably harvesting it an…

That coastal habitat could also be used to support stocks of fish that people will actually want to eat.

Why not both? A few years ago I saw a promising project focused around floating containers with algae and oysters that also provided valuable habitat for fish

Cody'sLab has a few videos about growing his own algae for consumption which are pretty interesting: https://youtu.be/64cEmjtwRgw Personally, I'm not opposed to this kind of food but integrating it into your existing diet can be challenging.

Spirulina Is much happier warm. Harvesting is kind of boring. Got a 5 gallon bucket topper with a fine mesh strainer for engine oil. Scoop out a bunch, flush repeatedly with fresh water, you get a green gelatinous cake that doesn’t taste like much (tofuish?)

No one liked it. It would do in a pinch.

In my 20-30s, I was a long distance cyclist which required a high carb diet and I had persistent belly fat. Now I primarily lift weights and eat a high protein diet and I have lost all the belly fat and as an added bonus, my posture is no longer perma-hunched.

Which version of you would have done better at something like... running around with your kids at the park? Or running a mile to catch a train? My main point is that defined abs and a giant chest and arms have little to do with health and performance, but the body-building culture has convinced us all that they do. It got ridiculous in the 90s when Arnold and Stallone were portrayed as heroes good at everything due t…

Technically, I would have been far more injury prone running during my cycling days because of the terrible imbalances due to "mono sporting" as a cyclist. And I am not a musclebound gym rat now either. I spend more of my exercise time walking than anything else these days.

Not trying to sidestep your point here though and I understand and agree with what you are getting at re: over focus on lifting.

> Some are quite nutritious, some give us tummy troubles, some at excellent sinks for CO2 You forgot some are potent neurotoxins

That's "blue-green algae", a type of bacteria, that produces neurotoxins. Way different than the kinds of algae they're talking about here.

Yeah! I was thinking "ah the room isn't sealed, nor is the house for that matter" but I can probably get interesting measurements with a simple CO2 meter.

CO2 meter and a 30 gallon garbage bag to seal the meter inside along with the algae?

If you try to measure CO2 usage, be aware of the fineprint in your sensor, depending on the sensor it may just take the lowest reading over some period and self calibrate (incorrectly) as normal air CO2 concentration (~400ppm)

https://www.extech.com/products/CO240>

Automatic CO2 Baseline Calibration (ABC) The ABC algorithm continually tracks the sensor’s lowest reading over a fixed time interval and slowly corrects for any long-term drift (as compared to the expected fresh air value of 400ppm). The ABC period is 15 days, during which the ABC function default is always on.

>because beans and rice are healthy I disagree. A high carb diet make me fat. A high protein diets does not. There is no vegan way for me to eat my daily protein target without eating far too many carbs along with it. (edit: I should have stated that there is no way beyond eating highly processed foods)

2 things: - everyone is different - there are plenty of low-carb, high-protein vegetarian sources (see: tofu)

Actually, the problem with tofu is that it has a very high fat to protein ratio. If I were to get my protein from tofu, I'd take in way too many calories from fat.
