<v Speaker 1>to brain Stuff from how stuff works dot com where

0:00:19.880 --> 0:00:30.960
<v Speaker 1>smart happens. Hi Am Marshall Brain with today's question. Do

0:00:31.160 --> 0:00:34.400
<v Speaker 1>race cars use gasoline like normal cars do or do

0:00:34.479 --> 0:00:37.400
<v Speaker 1>they use something else? It depends on the type of

0:00:37.479 --> 0:00:41.640
<v Speaker 1>race car you're talking about. For example, Nascar engines burn

0:00:41.680 --> 0:00:45.760
<v Speaker 1>a hundred and ten octane leaded gasoline, Indie cars burn

0:00:45.880 --> 0:00:50.160
<v Speaker 1>pure methanol also known as wood alcohol, top fuel, dragsters

0:00:50.159 --> 0:00:54.160
<v Speaker 1>and funny cars burn nitromethane. Each of these fuels has

0:00:54.200 --> 0:00:58.680
<v Speaker 1>advantages and disadvantages. For example, the methodol fuel used in

0:00:58.680 --> 0:01:01.319
<v Speaker 1>indie cars has the vantage that it can run at

0:01:01.360 --> 0:01:06.120
<v Speaker 1>extremely high compression ratios, meaning more power and the engines

0:01:06.160 --> 0:01:09.800
<v Speaker 1>able to handle turbo charging easily. Methodol also has a

0:01:09.880 --> 0:01:13.839
<v Speaker 1>nice safety feature. You could extinguish a methodol fire with water.

0:01:14.520 --> 0:01:19.480
<v Speaker 1>D ten octane gasoline also handles high compression well. Nitral

0:01:19.560 --> 0:01:23.440
<v Speaker 1>methane is basically a liquid explosive and contains a great

0:01:23.480 --> 0:01:26.479
<v Speaker 1>deal of energy per unit volume. It has more than

0:01:26.560 --> 0:01:30.120
<v Speaker 1>twice the energy is a similar amount of gasoline. Do
