rev up your engines, today I'm gonna be
telling you the truth about hydrogen
cars, now to begin once you have to
realize it there's two types of hydrogen
cars, there are cars that burn hydrogen
in an engine to propel the car along and
there are fuel cell cars, that use the
hydrogen in a fuel cell to generate
electricity and the cars are actually
electric cars with electric motors, now
the United States Air Force is presently
experimenting with both types of
vehicles in Hawaii, they're creating
their hydrogen through electrolysis they
can make it out of seawater it's no big
deal it's just takes energy and realized
that the first type of hydrogen car, a
car that just burns hydrogen gas is no
different than many cars people have
today
where they run off of natural gas,
compressed natural gas, you see a lot of
city buses nowadays in big cities that
say running on clean natural gas, you can
actually run any internal combustion
engine off of hydrogen if you really
want to, it's nothing to convert this old
Celica to run on natural gas or on
hydrogen, it's actually a lot more
efficient than using gasoline, the
gasoline has to be sprayed to make a
vapor to burn the gas is already a gas
it just added it and ignite it and away
you go
the only problem with converting stuff
to run on gas, either natural gas or
hydrogen is, you have to store the stuff and
you need very good safe containers now
they're using a lot of carbon
fiber-reinforced tanks on the
experimental ones that's the big hassle
is, you gotta store the gas somewhere and
the range is a lot less than the tank of
gasoline because hey you'd have to have
a gigantic storage tank to go 400 miles,
where a small gas tank and a small
engine could easily do that, now if you
did turn your car into a hydrogen
burning car,
it actually would pollute less it would
last longer, it runs more efficiently, but
there is a hassle getting the hydrogen
gas of course, because as you can see on
the dots of this map, there are only 270
for hydrogen refueling stations in the
entire
planet, so in this respect you'd be
better converting your car to natural
gas, quite a few people all over the
world have, there's some areas where
natural gas is really cheap, so a lot of
people converted their vehicles to run
on natural gas, turning it into hydrogen
would be kind of foolish because you've
got no place to buy the hydrogen from,
now the second type of hydrogen car are
what people normally think about,
it's the hydrogen fuel-cell cars they
take the hydrogen gas, they run it
through a fuel cell which turns it into
electricity, which runs the electric
motor on a electric car, so these are
just electric cars that don't need
batteries to run them, they use a fuel
cell, there's actually one out now here
it is it's called the Toyota Mirai and
you can actually lease one today, at
least in California there are a few
hydrogen stations there and you fill it
up pretty much like you do a regular car
just takes a few minutes, and that fast
refueling is one reason I think if
electric cars ever become the norm, it'll
be a long way in the future, but if they
do the hydrogen fuel cell cars are
actually a much better idea than a car
that has a giant battery to run an
electric motor, and that's for two main
reasons, one there's only a limited
amount of lithium in the world there's
probably not enough to make the giant
lithium batteries for hundreds of
millions of people to drive electric
cars, and it's always gonna take a
reasonably long amount of time to
recharge an electric car battery
the faster they go, the bigger they are
the longer it takes to recharge the
batteries, if you've got just a normal
112 plug in your house and you got a big
Tesla it can take three and a half days to
charge that battery up and even at one
of those Tesla super stations, if you're
almost out of electricity it's going to
take you almost an hour to charge it
back up, and if there's hundreds of
people are waiting to charge up their
battery hey, it's going to take hours and
hours and hours, people won't stand for
that, now the hydrogen fuel cell car of
course is a non polluting vehicle, the
hydrogen goes in, out comes water vapor
and electricity, so they don't pollute
the air at all they're the cleanest
vehicle you can get your hands on, but of
course there's a problem of getting a
hydrogen, it would take a massive
paradigm shift in our society to move
from an oil base to
economy to one that's based on creating
hydrogen, now it's not that there isn't
any hydrogen, the oceans full of h2o
it can be turned from electrolysis into
hydrogen and oxygen and all the gases
can be used in commercial processes or
oxygen for medical processes, it just
takes energy, so if they wanted to make
giant solar plants that turned water
into hydrogen and oxygen, it'd be kind of
stupid to use coal or gas or oil to burn
that to create it and be kind of
counterproductive, but if you really
wanted to change the paradigm of society
to non polluting, it can be done with
enough money, and who knows what the
future will bring, but really if they do
want to create the hydrogen, we can run
the cars we already have on it, it's
nothing to convert it and then as time
goes on and these things get old and all
fall apart, they could switch to fuel
cell cars it would run on the same
hydrogen, and like anything else it's
just a matter of production scale if
they started mass-producing fuel cells
that run on hydrogen and create
electricity,
hey they will get cheaper and cheaper
we're with the all-electric car that has
a lithium battery, since there's a
limited supply of lithium on the planet,
hey it might not even be feasible that
there would be enough lithium to make
enough batteries to run the things, but of
course everything in our modern society
is capitalist, and since the price of gas
is really low now, Toyota seemed to come
out with their hydrogen fuel cell car at
the wrong time economically, because gas
is cheap so people don't really care, but
as oil supplies dwindle down, if they
want to make hydrogen from seawater and
run cars that use hydrogen fuel cells,
hey that sounds like the better idea
to me then cars with lithium batteries,
cause as I said the fuel cells don't
pollute at all, they just put out water
vapor and since you don't need to
lithium, there's no problem about not having
the materials to build the stuff with, so
now you know a little bit more about
hydrogen cars and what's actually going on
out there, who knows what the future is
going to bring but, hey my bet would be
on fuel cell cars instead, and the oil
companies yeah they'dprobably fight tooth
and nail but really, they're businessmen
and if they see finally the oil is
running out or the earth is heating up
too much they can switch all their
money into doing fuel cells instead, hey
look at World War 2 in Detroit, they went
for making cars to making tanks and
fighter planes, just like that so they
could give up with their oil refineries
and start making hydrogen instead if I
really wanted to, so if you never want to

videos, remember to ring that Bell!
