1.5 hours runtime for like half a liter of gasoline?? That's unbelievably inefficient. A half-liter of gasoline is like 15MJ, should power a laptop drawing 30W for a week.
Maybe it would be better with a fuel cell.

With the current energy prices for fossil, I feel like it'd be a smarter thing to charge them through off-grid solar.
seriousness aside, this is cursed and awesome. wonder how long it'd take for the tank to run out after running modded Minecraft w/ shaders?
My generator runs basically the same consumption regardless of whether you have a 150 or 300w load on it so probably the difference is going to be negligible.
Was about to say. I can't help but feel like it'd be easier to put solar cells on the back of the laptop and let them charge its normal battery.
I don't think a solar array the size of the back of a laptop screen would be enough to run it, but it'd definitely be enough to charge it.
How off-grid are you really, if you still rely on a grid-connected service to get the gasoline? Should have called it diesel-punk instead
"Your scientists were so preoccupied with whether or not they could, they didn’t stop to think if they should" 😅
actually that reminds me
there's a series on youtube about putting solar panels on machines and checking whether they generate enough power to power the device
so they put solar panels on a car and check whether the car runs,
they put solar panels on drones to check whether they fly
would this work for a laptop? how much solar panel area do you need to run the laptop? I assume 30W power usage, that means you need 0.15 m² solar panels under full sunlight, my laptop has like 15x20 cm which is 0.03 m² ... so, you could only use it 20% of the time to give it time to recharge.
Most laptops come with 100W bricks, 30W is consumption at idle but most consume around 60W when under load
With a super lightweight laptop, 5w is achievable during light usage. I have one that draws that. It's usable for Google Docs sort of stuff indefinitely on a 5w charger. It can also go down to ~2.2w with low screen brightness and very low load. It is absolutely terrible though, celeron 3855u. I got Minecraft Java to run at 60 fps though... But it was probably using 7-12w then.
With a modern arm chip, you could get pretty great performance at that power draw. My phone (snapdragon 8 gen 3) in power saving mode can be like 5-10x faster at about 6 watts it seems like.
Also just for reference, a human consumes about 100W of continuous power output throughout the day (24-hour cycle).
You can calculate this easily. WHO recommends 2000 kcal a day, which is 8 MJ, divide by 86400 seconds in a day --> 100W average consumption.
