MIT solar PV technology scalable, printable, incorporable into fabrics

[Crick]

This could be revolutionary. Virtually anything could now be producing electricity in the sun. A backpack, a tent, a tarp, the entire body of your car, your roof. Check our this article.

MIT's "Thinner Than a Human Hair" Solar Cells Are Now Scalable and Nearly Limitless

These solar cells are created through a method similar to printing T-shirts, but the result is a more flexible, durable, and efficient solar array

Outstanding. I freaking LOVE science.

Science may save us from ourselves one day.

Get back to us when they've made the necessary leap in battery technology to make a net-zero economy possible.
Until then, it's all a pipe dream by sheeple that don't understand math

I can't think of a better way to usher in the next glacial period other than converting visible light on a global scale which would have produced heat and converting it into kinetic energy in the middle of an ice age when the net warming is only 0.6 W/m^2.

Like you understand math?

Of course. Because kinetic energy never results in heat.

Not the actual kinetic energy (work) itself; just the losses associated with doing the work. Which relative to the work performed is low. Somewhere around 10 to 20% of the total energy.

total energy = work + losses

 

[ding]

And the same thing for potential energy. Converting electricity into potential energy does not produce heat except for losses from the conversion process.

 

[ding]

Losses are typical due to friction.

How much energy hits the panel versus how much would have warmed the ground?

If a Tesla uses 100 KW to go from point A to Point B, how much of that energy ends up as heat?

What part of kinetic energy and potential energy do not produce heat did you not understand?

How much of the 100 KW used by the Tesla didn't result in heat from friction?

As far as I can tell, assuming no significant change in altitude,
pretty much all 100 KW used by the Tesla is converted into heat by friction.

If you have a different number that supports your global cooling theory, post it.

Calculate the work and subtract it from the total energy. Because work - which can be kinetic or potential - does not produce heat.

Work to move the Tesla 100 miles north and then 100 miles south back to the point of origin
results in heat from friction. Pretty much 100% of it. Can you calculate otherwise?

What's the work in that 200 mile round trip?

How much work was performed?

 

[Toddsterpatriot]

How much work was performed?

I think all the work performed was overcoming friction.

Friction is subtracted from total energy not work.

What waste heat there is from electricity usage doesn't heat the surface of the planet. It radiates back to space. Solar radiation heats the surface of the planet. Reduce solar radiation enough and it will affect the planet's climate.
