What Does / Mean Between Words?
To Indicate Or
Often, when a slash is used in a formal or informal text, it is meant to indicate the word or. The examples below illustrate this meaning of the forward slash:
When leaving the classroom, the teacher noticed that a student had left his/her backpack. College freshmen should bring a mattress and/or cot to sleep on during orientation. If/when Mary ever shows up, we can all head out to the party together. Burgers or pizza for dinner? Yeah, either/or is fine with me.
Blah, blah, blah 100% efficiency. Blah, blah, blah 100% efficiency. Blah, blah, blah 100% efficiency, well as long as you take my definition of what efficiency is!
If you define efficiency as you see fit, of course your numbers will say anything you want!
You also take only what suits you from anything you read. Example, you quoted:
1) "In that sense, the electric heater is 100% efficient, since energy not directly turned into heat will be turned into heat soon." (Several other replies correctly point out that electric heaters are 100% efficient at converting electrical energy into heat.)
But you forgot to quote:
That isn't a very useful way of thinking about efficiency, though, because any form of energy in your house will probably decay into heat energy pretty quickly. Your computer, television, and refrigerator are 100% efficient at heating your house from this point of view, because although they do things other than generate heat, the energy they use to do those things becomes heat in short order.
So, wow! The electric heater is as efficient as my TV to warm up my house. What a brilliant discovery! Thanks for enlightening us that much here on Slashdot. I would never have thought about this by myself if you hadn't been there to mention such a trivial fact! Never mind that I mostly heat my house with computers.
The sad part is that some people seem to rely on people such as yourself to "save the planet".
Talk about superconductors or other stuff like that if you want to help, your archaic and simplistic views aren't going to help anybody.
You are debating all by yourself again about the best alternative. I don't get into these religious debates.

And I replied:
Power lines leak by design warming up the outdoors and irradiating the air, wasting 4.70363517 × 10E18 joules every year.
There is no easy, 100% efficient solution!
Furthermore, that amount of wasted electricity is just a little less than what India consume every year and more than what Russia and more than 200 other countries consume by themselves every year!.
The power lines are a giant resistance heater!
Now, talk about 100% efficiency without a smile!;-)
That's all there is to it really...
Now, since you made me waste all that time: I am going to make you jealous a bit: Where I live, 85% heating is electric and 98% electricity comes from hydro. I work on power lines.
That natural gas also has to come from someplace. Typically someplace hundreds or thousands of miles away.
The point is that gas pipelines are not supposed to leak while power lines leak by design warming up the outdoors and irradiating the air, wasting 4.70363517 × 10E18 joules every year.
It's strange how everyone immediately points out generating and transmission losses for electricity but completely ignores the cost of extracting, processing and transporting fuels even before you burn them.
Nobody but yourself is arguing here about gas being better than electricity. We just stated facts that you seem to blind yourself from seeing. On the other hand, saying that something is 100% efficient makes you look silly.
His defense didn't work because: "Autopilot is intended for use only with a fully attentive driver"! Same thing is said in TFS of this article with the fire truck story.
If you think about it, a "fully attentive driver" ready to take control at any time seems to me like the driver needs driving school instructor skills where the instructor can take control of the car if the student screws up. Driving school instructors need more skills than a casual driver. It seems to me like being able to take over on the fly at any time might be harder than when you already have control in the first place.
Does driving a Tesla require a driving school instructor license? Maybe it should if it doesn't...

If it's 0C outside and 25C inside, the electric heater is about 8% efficient.

4.70363517 × 10E18 joules wasted by power lines every year to warm the outdoors for the whole planet.
Well, power lines in the US waste 8.4 x 10E17 joules every year warming the outdoors.
In perspective, planet Earth gets 3.8 x 10E24 joules from the sun every year.
There is no easy, 100% efficient solution! :)
