Speaker 1: Welcome to brain Stuff from house stuff works dot com

2
00:00:03,600 --> 00:00:14,680
Speaker 1: where smart happens. Hi Am Marshall Brain with today's question,

3
00:00:15,000 --> 00:00:19,279
Speaker 1: how is it possible to drive across Antarctica given that

4
00:00:19,360 --> 00:00:22,440
Speaker 1: it's thousands of miles and there's not a single gas

5
00:00:22,480 --> 00:00:26,079
Speaker 1: station along the way. Once upon a time, like about

6
00:00:26,120 --> 00:00:29,159
Speaker 1: a hundred years ago, getting to the South Pole in

7
00:00:29,440 --> 00:00:34,560
Speaker 1: deepest Antarctica was hard, very very hard. An expedition in

8
00:00:34,680 --> 00:00:37,839
Speaker 1: nineteen oh seven failed to reach the South Pole. It

9
00:00:37,960 --> 00:00:41,800
Speaker 1: was finally reached in nineteen eleven, and it was an

10
00:00:41,800 --> 00:00:46,840
Speaker 1: incredibly daunting project. Fast forward to two thousand and ten.

11
00:00:47,200 --> 00:00:50,560
Speaker 1: In the same way that Mount Everest was once unconquerable

12
00:00:50,840 --> 00:00:54,120
Speaker 1: but is now nearly a tourist attraction and has cell

13
00:00:54,120 --> 00:00:57,320
Speaker 1: phone coverage all the way to the top, Antarctica is

14
00:00:57,480 --> 00:01:01,520
Speaker 1: now being traversed in Toyota pickup trucks. It's still a

15
00:01:01,560 --> 00:01:04,760
Speaker 1: bit arduous, yes, but it would appear that anyone with

16
00:01:04,880 --> 00:01:07,759
Speaker 1: enough money can make it to the South Pole as

17
00:01:07,880 --> 00:01:10,679
Speaker 1: part of a vacation package. How do you do it?

18
00:01:11,200 --> 00:01:15,319
Speaker 1: You ride in highly modified trucks and you carry the

19
00:01:15,480 --> 00:01:18,120
Speaker 1: hundreds of gallons of fuel that you need in a

20
00:01:18,240 --> 00:01:21,560
Speaker 1: trailer that you toe behind the truck. In two thousand

21
00:01:21,600 --> 00:01:25,880
Speaker 1: and ten, a convoy of these Toyota trucks drove nearly

22
00:01:26,120 --> 00:01:29,119
Speaker 1: three thousand miles to reach the South Pole and then

23
00:01:29,200 --> 00:01:31,720
Speaker 1: come back. Now, it used to be that if you

24
00:01:31,760 --> 00:01:34,360
Speaker 1: wanted to drive around the South Pole, you did it

25
00:01:34,440 --> 00:01:40,399
Speaker 1: in highly customized, super expensive tracked vehicles that took years

26
00:01:40,400 --> 00:01:42,640
Speaker 1: to develop. How are they able to do it in

27
00:01:42,680 --> 00:01:47,000
Speaker 1: a normal pickup truck. The main modification that they've made

28
00:01:47,200 --> 00:01:50,640
Speaker 1: is they've taken diesel engines in these trucks and they've

29
00:01:50,680 --> 00:01:53,800
Speaker 1: converted them to run on jet fuel. The reason for

30
00:01:53,840 --> 00:01:57,160
Speaker 1: the jet fuel is because jet fuel is formulated to

31
00:01:57,200 --> 00:02:01,200
Speaker 1: work at low temperatures. Anyway, when jets are flying at

32
00:02:01,280 --> 00:02:05,120
Speaker 1: thirty two feet it's minus forty degrees fahrenheit up there,

33
00:02:05,200 --> 00:02:07,720
Speaker 1: so the fuel has to be able to flow at

34
00:02:07,840 --> 00:02:11,119
Speaker 1: very low temperatures. So by modifying the trucks to run

35
00:02:11,200 --> 00:02:13,760
Speaker 1: on jet fuel, they get rid of the problem with

36
00:02:13,880 --> 00:02:17,799
Speaker 1: diesel fuel turning to jelly and cold temperatures. They make

37
00:02:17,880 --> 00:02:21,880
Speaker 1: some other modifications as well. For example, they put thirty

38
00:02:21,919 --> 00:02:24,880
Speaker 1: eight inch tires think about a tire that's over a

39
00:02:25,000 --> 00:02:28,760
Speaker 1: yard in diameter and very wide on these trucks, and

40
00:02:28,760 --> 00:02:31,640
Speaker 1: they run them at low pressure so that they don't

41
00:02:31,760 --> 00:02:35,160
Speaker 1: sink into the snow and ice of Antarctica. They also

42
00:02:35,280 --> 00:02:37,880
Speaker 1: put rails on the truck in case it falls into

43
00:02:37,880 --> 00:02:41,240
Speaker 1: a crevasse, and they have amountable crane so that they

44
00:02:41,240 --> 00:02:44,519
Speaker 1: can take the tanks of fuel. They bring the fuel

45
00:02:44,560 --> 00:02:47,360
Speaker 1: in normal steel barrels. They have to be able to

46
00:02:47,400 --> 00:02:49,920
Speaker 1: lift those off the trailer and move them into positions

47
00:02:49,960 --> 00:02:52,799
Speaker 1: so that they can do refueling, so they have a

48
00:02:52,880 --> 00:02:55,240
Speaker 1: portable crane that mounts on the front of the truck

49
00:02:55,280 --> 00:02:58,639
Speaker 1: to help them do that. Obviously, they also beef up

50
00:02:58,680 --> 00:03:03,079
Speaker 1: the heating system, do some work on the suspension, reduce

51
00:03:03,160 --> 00:03:05,840
Speaker 1: the cooling capacity, things like that so that it can

52
00:03:05,880 --> 00:03:10,280
Speaker 1: adapt to the extremely cold temperatures. And then when they stop,

53
00:03:10,360 --> 00:03:13,040
Speaker 1: they just leave the engines running so that they don't

54
00:03:13,120 --> 00:03:16,360
Speaker 1: have to start them at minus forty degrees. The company

55
00:03:16,400 --> 00:03:19,400
Speaker 1: that did the modifications is called Arctic Trucks, and if

56

Speaker 1: you go to Arctic Trucks dot com you can see

57
00:03:22,200 --> 00:03:24,959
Speaker 1: the kinds of modifications they're making in some of their

58
00:03:25,000 --> 00:03:31,480
Speaker 1: future thinking in the Arctic and Antarctic Truck realm for

59
00:03:31,639 --> 00:03:33,880
