/diy/ - Do It Yourself

[Anonymous No.1269866]

so, theoretically, how strong would a drone have to be to lkft a shipping container(for the sake of discussion, fully loaded)? would motors be able to pull it off or would it need engines? how would you go about stabilizing it with the potential for shifting cargo? how much fuel/battery life would be needed to say, carry it from california to hawaii? how far inland would be possible? let's say budgets are either $12,000 or unlimited. would claws, magnets or both be best for securing it to the drone? i'm kind of new to drones in general. asking for a friend.

Look at your question.
>how strong would a drone have to be to lkft a shipping container(for the sake of discussion, fully loaded)?
It would have to be strong enough to carry a fully loaded shipping container.
What’s the container way?
What are you putting in it?
What’s your gross weight?

The army uses chinooks to move similar loads. Base your research off of that and you should have an easier time with your unknown calculations.

Well a fully loaded 40 ft shipping container runs a bit under 60,000 pounds. A modern chinook can lift around 20,000 pounds. So I'm going to go out on a limb and say yes, you need engines. Big engines. Lots of fuel. Probably some wings to generate lift as well if you want to go crossing the ocean. To be honest, you're just building a cargo jet at this point, and iirc there are a couple of good threads archived somewhere if anyone has the links

OP, this is the dumbest fucking thing I've read in years and I wanna know exactly how dumb, so I'm gonna answer it.
Short of hooking up a quad to a power supply and measuring it, I'll just check online. I'm getting around 150-500 watts/kg.
So let's be generous, but safe, and say 250W/kg.

Let's use a 20 foot shipping container, itself weighing 2,500kg, maximum payload capacity 25,000kg, with a volume of 33 meters cubed.
Knowing you'll be transporting weed, with 1oz/liter, 28 grams per cubic decimeter, 10x10x10 cubic decimeters per cubic meter, x 33 cubic meters, 28*10*10*10*33/1000, that's 924 kilos of weed plus 2500kg of shipping container, total 3434 kg, at 250 watts per kilogram, that's 858 kilowatts, or about one million two hundred thousand horsepower.
So, the biggest battery you could get for a quadcopter, a 1KWh, would last around 4.19 seconds, but would burn itself out in a fraction of a second trying to deliver that. We could add a thousand of these batteries, to give you an hours flight time, but that would nearly triple the weight. You could hang the batteries off helium balloons, but by that point balloons would have been a better starting point.
Now, Hawaii to cali is 4 thousand k's, so at 100kph that's 40 hours. So you'd need, bare minimum, 40 thousand kilograms of batteries.
Now, there's 9kwh in 1KG of petrol, so perhaps that's better. It also saves you trying to work out where the fuck to find a 200kw brushless motor.
Ah fuck, the old tesla's used 310kw motors, so that's nice. Still, fuck that for weight. Either you're blimping your batteries, or using a petrol engine to generate electricity, and you're losing far too fucking much there, so just use proper combustion engines.

Now let's recalculate. 858kw for just cargo. 858/9kw(per liter)=95kg. Divided by 0.3 for efficiency, 316kg of petrol. Fuck, that's basically nothing.
Oh wait no, that's per hour. That's 12,600 KG of petrol to shift 3,400kg of weed. We're ignoring engine weight here.

As someone who works with high pressure steam systems all day, I can tell you that using steam for lift is so fucking retarded that I jumped to hydroxy instead, something much more viable.
Hydroxy you just have to contain. Steam you have to keep hot, and then you might as well just heat air, as air doesn't fucking condense under the slightest pressure.
And "Steam from the ocean" is fucking silly, water vapor's just a component of the air. The air you're trying to be lighter than. Even if you could somehow capture 100% water vapor it'd still weigh just the same as the rest of the air you're trying to be lighter than.

>could you also make your explinations in the us system?

You'd need motors 200x as powerful as the strongest drone motos currently available.

Fine, let's do this shit.
First is weight. If it's not weed, then let's just fill up a shipping container to max capacity.
A 20 foot container weighs 5 thousand pounds.
5,000.
It can hold 55 thousand pounds
55,000.
So 5,000 plus 55,000 is 60,000
60,000 pounds.
Now, we know you can lift 1kg with 200-250 watts, or 2.2 pounds. So to get energy to lift and hover 1 pound, we divide 250 by 2.2.
Because the figure is not exact, let's just say 100 watts per found.
Now, at 60,000 pounds, that's 60,000 pounds each using 100 watts, so 60,000 times 100. That's 6 million watts, 6,000,00 watts. A kilowatt is one thousand watts, so to make it into kilowatts we divide by 1000. 6,000 kilowatts.
That's 15 of the electric motors that drive the Tesla Model S.
Let's continue

[Anonymous No.1270949]

>>1270943
So, to float your container, you need to use 6,000 kilowatts of ENERGY, either from petrol or electricity.
Now, that's a flowing speed, it's like miles per hour, it's how much energy you're using at any time, not an amount used.
So, if a lightbulb uses 1 watt, or, let's say, every second it needs one cup of electricity poured into it, if we wanna see how much it uses per hour we leave it on, keep pouring one cup of electricity into it every second, then after an hour, we can say it used one watt hour of energy. A constant flow of one cup of energy per second is called a watt, and the total energy used if you do this for an hour is a watt hour.
So, if you then get 10 of these lightbulbs, you could use one watt hour of energy to power them, but you'd use it up 10x quicker.

So, if you've got six million watts, if used for an hour, that uses up six million watt hours. Doing this for 40 hours, to get from hawaii to cali, would use up 40 times six million watt hours, or 240 million watt hours. Divide by a thousand to get kilowatt (thousand watt) hours, 240 thousand kilowatt hours (240 thousand thousand watt hours).
Now, a 1kw battery (costs $1,500) but also weighs 9 pounds. And we need 240 thousand of these.
So, just to carry the original 60,000 pounds of container and cargo, we need 240 thousand 9 pound batteries, or 240,000 times 9, two million pounds of batteries, that would cost 240,000 batteries times $1500 each, Three hundred and sixty million dollars.


>>>1269934
>i don't think this is a good idea because then i'm limited to going over water.
OP, if you think "Collecting steam off the ocean to float" is a good idea, then what do you think about this image? Maybe you could rotate it and use it to fly?

[Anonymous No.1270954]

>>1270949
Long story short op, to carry 60,000 pounds of cargo, you'd need 30 tesla model S motors that didn't weigh anything, and also three hundred and sixty million dollars of batteries that would weigh two million pounds.

You may be too fucking dumb to follow my maths, no matter how much I spoon feed you, but now it's time for you to sit in a corner, understand that no matter what mummy and your teachers tell you, you aren't smart, you aren't clever or special for wanting to fly a container with drones, you're a total fucking idiot, and the sooner you understand just how fucking retarded your view of reality is the sooner you can grow up, learn how it really works, and actually achieve stuff.

I wish you the best of luck in life, I really do, but you need to understand how fucking stupid you are, by merit of not looking at this idea and going "Wow that's fucking retarded".


Here's a better goal: You and your fucking friend go build a quadcopter that can carry a brick. Not the hardest, they're only 3.5kg, fuck, 7.7 pounds.

So, 2 million pounds of batteries to lift 60,000 pounds of car. So do the maths again, now you need 66 million pounds of batteries (12 billion dollars of batteries) to lift the first 2 million pounds of batteries and 60,000 pounds of car.
So now you need 132 million pounds of batteries (396 billion dollars of batteries) to lift the 66 million pounds of batteries to lift the 2 million pounds of batteries to lift the 60,000 pounds of car.
So to >>1270046, that's what the spreadsheet showed. That the batteries will need more batteries to lift themselves, forever increasing the weight.

The difference would be marginal at best, especially considering to even get large mass of feathers in a shipping container you would need to compress them a good deal, removing most of the air and increasing density.
