Marine shipping is just about the most fuel efficient way of moving things between any two places, by a lot. A 100,000 dwt ship can get 1050 miles per gallon per ton of cargo. It takes about a teaspoon full of fuel to move an iPhone sized device across the pacific when I ran the numbers last.
- Vt71fcAqt7 2y agoInteresting. Could you give a brief description of how you got that number? Eg. what factors were considered.
- eric-hu 2y agoThose numbers match what comes up with a quick search: https://www.extension.iastate.edu/grain/topics/EstimatesofTotalFuelConsumption.htm https://www.extension.iastate.edu/grain/topics/EstimatesofTo... That study uses 1,043.4 mpg for the fuel economy of a 100,000 dwt ship. Videos of transportation ship engines are cool. Each cylinder is wide enough for a person to lay down inside it. https://youtu.be/G0eMyA388bE https://youtu.be/G0eMyA388bE
- School-Cotton 2y agoTo ship things to/from these fabs by sea you have to add the cost of shipping by truck between Phoenix and (presumably) LA. Not sure how big of a difference that makes.
- nine_k 2y agoChips are small, so one truck once a few days may suffice.
- CPLX 2y agoAirplanes. They use airplanes. We are talking about microchips here, possibly the highest dollar per gram substance that exists on the planet. The interest you'd pay just losing a couple days in transit time would exceed the cost of purchasing a dedicated private jet and the crew to fly it.
- jocaal 2y agoImagine the insurance...
- kstrauser 2y agoA semi truck carries +- 15 tons of cargo and gets an average of about 6 MPG, so about 90 MPG/ton.
- ponty_rick 2y agoTrains are pretty efficient as well.
