Efficiency

A bicycle is the most efficient machine in terms of energy expended for moving weight over distance.



A human on a bicycle is also the most efficient animal on earth in terms of energy spent for travel.



Bicycling is six times more efficient than walking.



Using a bicycle, it takes 35 calories to move an average-size person one mile (1.6 km). It takes 1,860 calories to move a person a mile in a car. So, the bicycle uses two percent as much energy as a car.

In my case the expense of Tylenol and coffee needs to be added in.

Remind me again how efficient I'm being on my bike when I'm grinding up a 15% grade

The downside: this is why it's so easy to ride a bike and stay fat.

My car is definitely less efficient with a bike on the back.

This seems like rather broad generalizations. Not sure how this "information" was arrived at, nor its merit. In fact, I don't even know what it means.

"Bicycling is 6 times more efficient that walking." What does that mean exactly?

The OP's post is to a library, so to speak. An online depository of information. He's not selling anything so there's no spamming. And there's no discussion there, only static information, which one can bring back here to discuss if so desired.

But the vigilance in general is appreciated.

Gravity

Really, gravity is only the description of the effects of Maas on Space. In effect, the effort you feel riding up a hill is caused by time slowing down as you get further from the center of mass. Apparently this hurts. Thank God time pulls us back toward Earths’ “normal” time. Something to think about as you attack your next rise.

I've seen some bike shops close to it. One when I was growing up just a repair shop. Old parts everywhere. The Bike Surgeon. Was a must stop for those doing TransAmerica

A train will move 500ton/miles per gal of diesel (35000cal). doing the math that's 1000lb/miles per 35 calories. Average rider say 200# = 200lb/miles per 35 calories

Both human and machine combusts energy into heat and work.
how much heat is released to work produced is efficiency. Something that is 100% efficient only produces work, and no heat.

Or sort of, basically is how much distance can a certain fuel get you. Energy of that fuel can be calculated by burning it (that's basically how calories is calculated). 1cal is 4.184J. They're both a measurement of energy. And likewise q aka heat is also a measure of energy.

Maybe it's me, but I've always equated a person's ability to convince me that they have a correct grasp on knowledge in a particular subject, by their command of linguistic skills, which would include syntax, grammar, capitalization, spelling, and punctuation. I don't see any fault in your spelling, so there's that.
