Methods of Transportation

Methods of Transportation
all right welcome to our brief lecture talking about

methods

of

transportation

for industrial development i stole the slides from a guy named david palmer who works out of eagle crest high school in colorado i am of course miss skull and i'll be your host for today's lecture a quick note about format which might influence how you take notes on each slide let me go ahead and show you what you're going to see is the type of

transportation

and then you're going to see some pros and
methods of transportation
you're going to see some cons and that's really what we're going to talk about then you'll also have a picture to help illustrate it so when you're going through and taking your notes it might be useful just to take two column notes basically in a table format have one side be pro and one sided con and then down the left-hand side just list diff the different types of

transportation

so starting to dig into it um the first type of

transportation

we're going to talk about
is air

transportation

right and air

transportation

has a lot of really good things going for it it's very fast it doesn't take very long to fly products from one place to another it's very secure it's much harder for hijackers for instance or for thieves to steal stuff because there's just fewer points at which um goods are out it's great and really awesome if we're talking about things like fresh foods they're things that need to be moved from one place from the
source to the market very very quickly okay so for instance the bananas from argentina or wherever they grow bananas in south america those they tend to fly because they need to get them from one place to another very very quickly okay um some of the cons some of the negatives it's very very expensive to ship things by error that's why for instance if you go to the post office and you say you want to ship something parcel post which means you're putting it on a truck it takes a lot
longer but it also costs roughly 25 of first class shipping right air travel it's also got a smaller tonnage of cargo so there's they're less there's less space in the plane even in cargo planes to ship stuff than there are say for instance on on the big ships um and speaking of big ships we talk about container ships or barges right in the picture we've got here is a great illustration of what one of those container ships look like you can see what it's really got
it's just literally those great big containers that you see on the back of semi trucks just stacked up and depending on the ship will depend on how deep they're stacked and how many are on the deck but they can stack a lot of cargo on and in those ships okay so it's very inexpensive in large part because the unit price is so little right the more stuff you can put into a type of shipping the less money each item costs and this holds a whole lot of stuff um it's also good because
the containers can be transported to and from the boats to trucks or trains really easily literally they just put them on cranes and drop them down okay so um it's inexpensive you can ship a lot of stuff most freight in the world by the way when it goes overseas goes goes by container ships okay and it's easy when you hit that breakable point to move it from the ship to a different type of

transportation

some of the cons it's very very slow it can take days or even weeks potentially
methods of transportation
for items to get from one place to another okay it's way better than it used to be obviously since we're using motorboats and not sailboats um but it's still especially compared to planes very very slow you run the distinct risk of piracy especially depending on where you're at in the world and how secure the the waters are right so for instance um not quite as much now but for a long time right off of the horn of africa by somalia it's a huge piracy problem there's still
a little bit of a problem but not nearly as bad as it used to be where literally you'd get these pirates you would come up and take control of the ship okay and then they would ransom the ship off one of the cons of this is that you can only use it where there's water as well right container ships only really work and when we say water by the way what we're talking about are oceans we don't send container ships up and down rivers right you'll never you won't find a
container ship on the columbia or the mississippi or something like that okay these are open water ocean port kind of ships okay so there's limits to where they can go which is also also kind of a con um another type of ship that often gets used um and works really well and we're talking about about certain types of freight are oil tankers obviously we use them for oil right and these don't we don't stack containers up on the top like what you saw in the previous slide but what
we do is all the freight goes into the bottom of the ship and in essence what it does is it helps to serve as ballast okay the trick with this is of course if you run into something this could be a huge problem as we find out almost every time there's a major oil spill right um it also makes the cargo very very valuable and easy to siphon off small amounts so um just something to consider right and also oil tankers tend to move tend to move slow so um we're transporting liquids in
particular like i said in particular crude oil from one place to another oil tankers are the way to go and there's some ways that they obviate and try to cut down on the likelihood of problems so for instance you'll notice in our diagram where there's empty space at both the beginning both the front and the back of the ship and then there's also a double hull that double hole by the way goes all the way up the sides um to try and make sure that if we're if the worst case
scenario happens that we're not spilling oil you also notice that the oil is in tanked rooms and each of those rooms has its own wall so they can actually um shut off parts of parts of the ship and shut off access to those those rooms if worst case scenario you know they they had a hole in the bottom of one of the rooms or something like that they could limit the amount of oil that gets out so moving on though talk about other types of

transportation

um next type we want to talk about are
methods of transportation
trains right my son's favorite method of

transportation

by the way and trains have a lot of a lot of really good things about them right they're relatively inexpensive they can carry large quantities of cargo um they're comparatively easy on the environment okay um but there's also some really bad things so first of all it's they're fixed destinations meaning trains only go where there are rails to go okay so um they only go to certain places and not everywhere in the
world has equal quality track okay and then speaking of track you come across the issue of maintaining the tracks so you've got to maintain not just the metal rails on top but also the cross ties underneath you've got to make sure that they're not blocked right um since we live in the pacific northwest in the puget sound region probably once every two three weeks something like that if you pay attention to the news you'll hear that the sounder train is blocked right sanders a
commuter train but the same principle applies what's happened is there's been a landslide up north and now the tracks are blocked so people can't get through on the train right same thing holds for um cargo trains we've got to maintain the tracks we've got to make sure that the tracks are clear that they're in good shape right and that the trains are able to to get through um another method of

transportation

this works especially well for liquids and we see it primarily
with um liquids and gases a lot of times oil for instance um are pipes so if you've ever seen a pipeline it's quite the thing you see they carry so some of the pros they carry large quantities of cargo they're relatively inexpensive you build it you maintain it but there's not you don't have a lot of labor costs or things like that that go into it right there and there they work really really well for liquids and gases okay um some of our cons of course that you've got
fixed destinations so the pipes go where the pipes go and and if you want to take it anywhere else you got to put it on a different method of

transportation

okay um maintaining those pipes can potentially be expensive because i know for instance back home up in alaska with the great alaska pipeline you literally during hunting season every year you hear about people who shot a hole in the pipeline and now there's oil spurting out somewhere along the way right so then not only does the they
have to shut down the pipeline or at least part of it they have to patch it and fix it or replace the segment most likely replace it but then they so they've got costs in terms of the downtime they've got cost in terms of the replacement but they've also got costs in terms of cleaning up the environment and so those are all things that need to be considered when we're talking about about pipelines and about pipeline maintenance um pretty sure this is our last slide here so we
talk about sending things via truck on the road this is probably the most popular way certainly here in the us to to ship stuff is so some of the pros it's very very flexible trucks can go almost anywhere right see you see cargo trucks driving all around seattle all the time you see them on the freeway you see them in small towns that's especially when we're talking about um shorter trips it's very very quick comparatively right and it literally can go to a door in a way that
that trains can't and planes can't things like that that's why oftentimes the last segment of

transportation

will be on a truck okay but some of the downsides right trucks have smaller capacities they you have the cost of um gas which fluctuates so right now it's down right it's down to i don't know 250 a gallon give or take here in the puget sound last i looked um but it could be as high as there are points where it was actually almost upwards of almost five dollars a
gallon so you've got fluctuating costs there in a way you you don't have as much trouble with with some of the other ones you've also got the cost of the driver right and truck drivers are not not cheap to pay and make pretty decent living um and depending on how far you want them to go right technically like everybody else they can only work about eight hours a day so if you need them to take a 10 or 12 hour drive now you're not only paying them for the time they're on the
road but you may also very well be paying for them to stay overnight somewhere right hotels aren't cheap paying for meals and things like that is part of the part of the trip so this has been our lecture talking about

methods

of

transportation

and industrial development some of the pros and the cons we looked at air travel we looked at trains we looked at boats and container ships we talked about pipelines we talked about trucks and other vehicles and looked at what are again some of the
pros some of the cons of each of those

methods

of

transportation
