Why nobody makes laptops with solar panel on the lid?

Solar panels are already pretty good, but they need to be set up properly. If your panel isn't permanently facing the direction of the sun at about 45 degrees, it's not worth it; tracking solar panels are even better.
Any case where solar panels are flat on the ground or otherwise not positioned to be in good sunlight, you're just wasting your money.

yeah pretty much this, shit gets hot quick too

how about something like that

No. 6-12 square meters of area or some such should do the job okay with non tracking panels.

There are solar power calculators online, I could link you to one from this country if you want to try a calculation on a reasonable roof, gimme a moment.

Swiss government website, pick real house roofs or walls:
uvek-gis.admin.ch/BFE/sonnendach/?lang=en

But... solar fraking roadways?...

No. No. Also not solar walls for now, unless it's a heat reduction measure (usually not interesting regardless).

Just solar roofs and solar installations angled correctly at the sun, maybe tracking the sun.

solar panels are crap we need a fusion rod to siphon photonic energy directly from the sun and covert it to electrical power. Be more chad about it

Solar panels have terrible energy return and you would have to leave your laptop closed and in the sun to see any results.

it works with smartphones, so it could at least work with batteries on smaller ultrabooks?

> terrible energy return
They don't. They are really pretty good overall.

But a laptop's surface area doesn't cut it and it also isn't going to be set up properly every time unless you add motor gizmos that automate ot, which is unlikely to make sense at this point.

And people are gonna toss the laptops and panels after like 5-10 years, not 30 years. Bad idea.

>heat
>the environment it's being used

you'd probably avoid yourself facing the sun with the lid because it would be fucking annoying

To charge a laptop would take a long time and therefore be likely unattended for much of it. To get good sun for a long time it would probably need to be outside. Laptop + outside + long unattended... Jamal's laptop now.
Good for people with secure rooftops and balconies with no power outlets.

Why not get a crank-powered laptop?

Why nobody makes laptops with a crank handle on the side?
Or what about a laptop you shake to charge?
Or a geo-thermal charged laptop?

Still not good for them because if they just set solar panels they'd be out there generating solar power all day long rather than just in the evening or whenever they're actually on top of the roof with their laptop. And the panel won't get tossed after 5-10 years or whatever period average people toss laptops nowadays.

>Why nobody makes laptops with a crank handle on the side?
Too inefficient. Bike-type generators kinda work if you're really desperate, though.

> Or what about a laptop you shake to charge?
No. Fuckall efficiency, you'll be mostly moving air and human body isn't designed to put much energy into this for shit.

> Or a geo-thermal charged laptop?
Because you'd AGAIN just do this as fixed installation.

>drives a solar roadway
>get permanent eye damage due to sun reflection

Because you don't want the laptop in the sun.
We already have ways to charge laptops with solar panels, just place them optimally and then connect your laptop, it is a better solution.
Or even better, just have a battery charger and have a dual battery system so you can swap batteries for days.

Just put a windmill on it and set it on the car roof on the way to work.
Free charge.

There are already portable solar panels to charge items.

I would have gotten one, but I'm a waitfag waiting for the next jump in photovoltaics and efficiency
You should connect to a bike instead.
Also, geothermal is a very limited source of power which is only viable in specific places around the world.

>Free charge.
If that was the case, why don't we put windmills on cars in the first place?
>install windmill on car
>never pay for gas again
:^)

if you are going to leave it closed for several hours then chances are you are at home, so why not just hook it up to an actual solar panel for charging?

Just use a free energy harvester, you can get some schematics on the best pajeet YouTube channels

That is a slightly more sensible idea overall, but not as sensible as just using a diesel generator.

Also, keep the same windmill on a house roof and it generates some power without expending fuel on reduced car gas mileage. On a pole, It'll probably be in a windier spot than a car when it's parked, and you can't put such a high pole on a car anyhow.

BTW let me clarify that even with a bike generator, you really want a power efficient laptop that only uses like 5W. You're still going to pedal like an hour or two to charge it.
And mass-wise, getting that energy in food isn't as efficient as in burnable fuel. It's a weird emergency measure.

You'll probably then also see that solar panels are pretty good. Yes, it's a 2x5m solar panel surface or whatever, but it probably does the job quite easily during most of the year for 30 or so years. Set that up instead if you can. or a wind generator. Keep the bike "crank" generator for full emergencies only.

does shit like this work?
voltaicsystems.com/generator

Not well, and this is expensive as fuck as compared to the Chinese backpack further up in the thread, or just foldable or better hard-framed panels with a stand.

BTW a quality 20Ah (Xiaomi or whatever) power bank with quick charge can be had for ~$25-35 on export from China, too.

The fun thing about various of the models available is that they can do pass-through charging, e.g. charge and discharge at the same time, which is nice for hooking them into a more simple smartphone-focused portable camping or whatever solar charging system.

Why DOES nobody MAKE laptops with solar panel on the lid

Did you read the thread? It's a bad idea.

>why does nobody strap a hotplate right behind an LCD panel
try putting your hand on a solar panel after it's been in the sun a few hours, those fuckers get HOT

i think his point was just grammar

oh right, didn't re-read OP

solar panels suck after you drop them on the floor

good idea
1m^2 solar panel at 20% efficiency makes 200W in 1 hour
macbook air 2018 has 0.062m^2 lid area so ~12W in 1 hour
apple gives 12 hour battery life and 50.3wh battery, 1 hour average would be 4.2W
So at sunny day you could get extra 3 hour battery life just by leaving your laptop under the sun for 1hour with closed lid.

They're also inefficient. You could most likely get similar energy density from just using the same weight in L-ions.

>having a laptop out in sunlight

Who does this?

taking your PC outside your basement is literally reason why laptops exist

>add solar panel on laptop lid
>have it sitting in the sun to get the charge
>battery explodes because temperature rises to 200C due to lack of cooling for the underside of the solar panel

Home -> dorm -> library -> lab -> workplace -> hotel

It never goes outside outside of a backpack/case.

wouldn't you have to leave the laptop out in full sun for like days for a few hours of use?

>Have to leave laptop out in direct sunlight for at least 10 hours to get even 25% charge
>Heat, the one thing aside from water that outright kills a laptop
>Lemme just subject my laptop to melting tier temps for 10+ hours
You're retarded.

insufficient surface area for required voltage

Solar panels run on light, not heat.
In fact, they don't like heat. If they get hot their efficiency drops.
