If those teslas are produced in China then we don't have this significant part of emissions from shipping. There won't be battery packs of that size within our horizon. Buy local. As Mahatma Gandhi advocated. An ethic now abandoned in consumerism frenzy, and Indian farmers are committing suicide on a scale never seen before.

For those interested in veering off topic into uncharted shoals, here is Gordon Bok's rendering of the narrative memoir of Karl Edstrom, who was tracked down in a nursing home when in his 90s, as the last member of the original crew of the Hesper. Among other things, he tells of the bewilderment of the "French ladies" who came down to the docks to welcome the vessel upon its arrival in Le Havre, not fathoming how a ship that size could be manned by just nine men.
My take of this is that the Age of Sail reached its pinnacle of economy and efficiency just as it breathed its last gasp. Or, to sound hopeful, when it was about to take a hundred year slumber?

The new IMO regulations are a big deal in this regard. By imposing sulfur emissions requirements, they force the ships to use a refined product rather than the "bunker oil" which is refinery waste product -- at which point their cheapest option is basically diesel.
Understood, however it's a change from the most horrible pollution imaginable to the second most.
Is this site reputable? I was afraid of its intense download extensions business..
Come on neroden you must see that trade has to be reduced exponentially..
I'm focusing on using economics as a pressure point to affect behavior. Getting ships into the diesel market means that they're buying a much higher-priced fuel, which allows for them to be undercut by electric shipping, allows for locally produced goods to have lower costs, etc...
I think that we should be clear that global trade is harmful.

Neroden just recommended Vox. I checked them out. Check out the infographics - I didn't read it as it is too long for me and I agree with the principle:
Clean energy technologies threaten to overwhelm the grid. Here’s how it can adapt.

Fuel consumption per distance is related to speed and displacement (gross weight). The classical formula:
Fuel_per_unit_distance = constant * speed^3 * displacement^(2/3)
A fuel tax would probably be more effective than a tax on weight. Cruising speed is the big driver here, having a power of 3, while weight is sublinear having a power of 2/3.

OT for MA (con't here):
The Police realized the Tesla was likely on Autopilot and pulled in front of the car then slowed down to a stop.
As designed, the Telsa's traffic aware cruise control also slowed, and then stopped the car.
Note that if Navigate-on-Autopilot was enabled and the lane-change prompt was disabled (not available yet), then the Tesla would have driven around the slowing Police car and continued on it's way.
Tesla needs to address this. They should connect a microphone to the self-driving software stack so that the car can react properly to Police and Fire sirens.
Cheers!

My apologies! I have no idea of any nefarious gnomes that may be lying await. I have either all or almost all of the inestimable M Bok's recordings in my collection, and all but one he has autographed for me.
Tells ya sumfin' about me.....
Of minor importance to the bunker fuel discussion: speaking on behalf of TMC members as a whole, there is, unfortunately for our own priorities another extremely valuable feature of bunker fuel, aka diesel #3 (or F.O.#3) (and perhaps even #4 but I'm not going to look that up).
It may be trashy bottom-of-the-barrel stuff, and cheap, BUT it possesses the greatest energy density of standard liquid fuels. Kerosene to bunker fuel represent a continuum, with the lightest and cleanest kerosene at the top....and fewest BTUs; then diesel #1 (which we use in AK winters), diesel #2 (what most think of as diesel, aka fuel oil #2), and #3. Heaviest, richest....and gels at the highest temperature (somewhere close to 20ºC if I remember aright) meaning that you wouldn't be able to use it for most terrestrial purposes but on the open main and in the close environment of a ship's hold, it works well.

I wonder if they'll be able to crack the no longer usable long chain fraction and get more diesel out of it or does the sulfur preclude that and it's disposed of unburned.
