There’s a bulk food store near me and it allows BYO containers (or you can use one of their compostable bags). It’s great! A little bit more work (you need to tare your/container write down the empty weight), but you get your goods in the container of your choice.

Can you not turn it into charcoal and bury it? I think that has a very long lifetime.

I wonder how carbon-negatove a bamboo forest would be if you harvest it, turn it into charcoal (or bury in a bog or something?), rinse and repeat. Afaik charcoal sinks carbon fairly effectively (???), unless you burn it obviously.

That’s what I love about these sapling trees, man. I get older, they stay the same age.

Super cool. Chemical fuels (hydrocarbons or even plant oils) have ridiculous energy density, which is nice for e.g. cars but absolutely crucial for fast, long-range air travel. I don’t think we’ll be saying goodbye to jet engines for a long time, and it’s awesome that we have ways of making fuel in a somewhat sustainable fashion.

The US Navy has experimented with this, but I think the idea is to use nuclear power instead of solar energy. Makes sense for an aircraft carrier with a big reactor and thirsty jets.

And the Chevrolet Suburban has been around since 1935.

Granted, it has gained over a ton in that timespan. But it hasn’t really gained much since 1973.

1400W for a minute is insane. You are either a pro track cyclist, or you should quit your job and become a pro track cyclist!

Rule of thumb efficiency of humans is about 25%, which is about the kJ to Calorie conversion, too — so 14kJ of energy output burns ~14,000 Calories.
