Yikes!

Looking for somewhere in Fossil Fuel Free for this, it doesn't seem to fit in Aerodynamics:

That's the Alessandro Volta, with a Toyota Highlander hybrid drive train swapped end for end.

Any other measure of "good nature" is fictitious because Gaia isn't real, and there aren't any other species with value systems. If salmon are "good", it's only because we say so. Apart from humanity, nature doesn't care if salmon exist or not.
The message from biologists is that, it is the 'rate' of change which evolutionary adaptation cannot keep pace.
Crustaceans, for instance, cannot evolve the ability to form body shells within a carbonic acid environment , as is seen rapidly accelerating in the world's oceans.
The entire marine food chain cannot evolve fast enough to survive without under- sea- ice algae, which forms its base, at the pace that we're losing polar sea ice. Once we achieve a 'blue ocean event' it's game over.
A collapse of the ocean fishery may be of no concern.
Soylent Green will get the 1%-ers by for awhile.

Odd enough, sometimes an "invasive" species may become the most effective way to keep the food chain sustainable somehow. When it comes to fishing resources, it's been true to some extent in my country.

I guess this falls under the purview of 'renewable energy'?

Just A Car Guy: there's a guy on the South Pacific island of Vanuatu that makes and sells a coconut oil mixture of 85% coconut oil and 15% kerosene for use in diesel engines.
Quote:
Tony Deamer, who runs a garage and car hire business in Vanuatu's capital Port Vila. makes “Island Fuel” which contains 85% of the purified and filtered coconut oil blended with 15% kerosene. No modifications are required in the diesel engines that use Island Fuel; however, engine pre‐heaters are recommended for colder areas.Tony Deamer says that this fuel has been tried and tested over many years and is now ready for retail sale. Unfortunately, the laws of Vanuatu do not allow the sale of Island Fuel, so he sells only the coconut oil to interested car owners. The minibus fleet owners in Porta Vila have been blending their own Island Fuel since 1995. The bus operators are completely satisfied with using it and they are reporting an increase in kilometers per litre when operating with the Island Fuel.
[snip]
Deamer has also developed a simple, gravity-feed filtration system which removes water and free fatty acids from the oil, thereby lowering the temperature at which it solidifies. Mixing the purified oil with either diesel or kerosene also prevents it from thickening. In 2002, over 200 minibuses on the island were running on a coconut/diesel mixture....

When the engine has indirect injection, the usage of vegetable oils actually improves the fuel-efficiency. Probably those minibuses to which a mileage improvement was reported are Toyota Coasters with the 1HZ engine.

Would that be in the context of 'human' consumption, or in the larger context of the general marine biosphere?
Humans can and do 'adapt' on a dime ( Peter Pan / Jif ). I'm uncertain about the ability of other species, which are genetically programmed to seek a specific food supply, one in which they've relied upon for millennia.
Estuarine harpacticoid copepods for instance.

Not only marine. I have seen it at some rivers and lakes where most native fish species could no longer live, yet catfish and sometimes tilapia grew steadily, not only being used for human consumption but also sustaining other wildlife such as alligators.

Did you watch the video I linked on post 190? I filmed that in 2019, yet since 2003 I knew there were alligators in that very same place which is heavily polluted BTW.
