Oh god I wish. I remember seeing some documentary of a guy that was big into renewable energy engineering. Something about creating a whole highway made of solar panels.

Not only would that be incredibly efficient, but it looked cool too. He had a prototype ready that had LEDs built into it you could program to warn drivers of hazardous conditions and stuff. All built into the road.

I'd just hate to see the highway get finished and then fall apart some way or another. I'm sure each panel is much more expensive to build and place than just pavement.

Even 100% efficiency wouldn't make solar viable on a really large scale. Also I hate the usage of the v for frequency instead of f; it's easily confused with velocity.

You are absolutely terrible 10/10 if trolling

My main issue with the solar roadpanels is dirt/oil/other stuff permanently staining the glass lowering the panel exposure and illuminance of the LEDs.

It's the letter nu...

And 2π = 𝜏

Are we done here?

>>6556500
Actually 𝜏 = <span class="math"> \frac{1}{c^2}\frac{\partial^2}{\partial t^2}-\frac{\partial^2}{\partial x^2}-\frac{\partial^2}{\partial y^2}-\frac{\partial^2}{\partial z^2} [/spoiler]

he probably means as a way to replace power plants, which is true since the sun hits earth with max 1kW/m^2, ofcorse that is not to say that we can't find a million other uses for them

>>6556545
>max 1kW/m^2
off by three orders of magnitude m8

>>6556555
holy balls, i must have look at local, my bad

>>6556558
no you're right, it's about 6kW/m^2
The picture I had was annual

>>6556545
>100% efficiency

And? Please finish that thought.

now I know the main chemical used in the 'eliquid' is propylene glycol, which is found in food and is safe for ingestion. My question is what do you think the effects on the lungs are of this chemical and do you think that the e cigs are better or worse than regular smoking?

What does that have to do with anything in this thread?
Did you accidentally reply when you meant to make a new thread?

yes I'm not even sure how i managed that

in respect to this thread thin film physical vapor deposition or chemical vapor deposition is the way forward for pv cells. They are thin and light so you could self installed. They could potentially cost less to make because you dont need a shit load of silicon. They have predicted greater efficiency but early days yet

I though it was power transmission issues.

You can make lot of small amounts of energy everywhere, which does give you lots of energy. But getting said energy from all this small sources requires a lot of other steps which creates a lot of loses resulting in a grossly inefficient system that makes one question if it will be a net asset.

You are not going to get tiny DC currents to transmit 50 miles without a bunch of superconductors and converting each one of them to AC is going to be a bigger pain then you think.
