Riding a short distance vs riding a long distance is irrelevant. Both systems require an amount of energy per unit of distance. Because the energy is supplied in different ways, there is a different amount of carbon emitted of per unit of energy.

Here's a source, dickface: https://www.ebikes.ca/documents/Ebike_Energy.pdf

A watt hour is equal to 0.86 nutritional calories. My estimate of 40 watt hours per mile converts to about 35 kcal. Estimates of the energy taken to pedal a bike are about 30-40 kcal/mile. That checks out!

1 kilowatt hour is equivalent to 860 kcal.

1 kilowatt hour from a coal power plant generates about 1.0-1.1 kg of CO2.

For a typical Western diet, studies suggest that the average emissions associated with food production and transportation can range from about 0.5 to 2.5 kg of CO2 per 1,000 kcal of food consumed. (0.4-2.1 kg of CO2 per 860 kcal)

The ebike generally has a smaller environmental footprint than the analog bike, as most sources of power produce less CO2 than coal power plants and most people eat more meat than necessary, putting them in the higher range of the food CO2 production range.

I'm having a hard time finding a source but I read an article claiming that unless you're vegetarian, a traditional bicycle will have a higher carbon footprint (even taking into account the battery manufacturing) than an ebike, due to how inefficient it is to grow and transport food when compared to production of electrical power.

Ebikes are way more efficient than electric cars, too. I calculated that my bike uses about 40 watt hours per mile, compared to about 250-350 for an electric car.

The surface area of the box is about 135 inches. If this surface area were spread over a sphere, it would have a diameter of about 6.5 inches and a volume of nearly 150 cubic inches (nearly twice the volume of the uninflated box!). 150 cubic inches of osmium weighs about 120lbs.

So, indeed you could exceed the weight limit of the box by ballooning it out and filling it with something that's at least 7/12ths as dense as osmium (or a little more dense than lead).

It seems like your post is an attempt to normalize what the Trump administration is doing. It's not normal.

You're right, maybe there's nothing to see here. I forgot that people start setting cars on fire as a goof.

Haha, I mean, we're definitely arguing over semantics but you're saying something equivalent to, "No, don't eat ice cream. Put some in your mouth and then swallow it, but don't eat. We never eat."

Haha. Would you please also tell the Republican party that you'd appreciate it if they could find prettier ways of destroying our government and constitution.

Think whatever you like but jury nullification is when a juror votes "not guilty" when they actually think someone is guilty of a law that they disagree with.

What you're describing has a name, and that name is nullification.

Horray, we're great again!

Are you mentioning this because of gun ownership in the U.S.? Not many people carry guns every day. Even if they do, they’re not likely to draw their five-shot .38 special against a group of ICE agents in body armor.
