Why Don’t We Have Water Powered Cars Yet?

Hey there, welcome to Life Noggin! Hey there! Welcome to my garage-slash-workshop-slash-Olympic-sized
swimming pool room. And it’s the perfect place to work on my
new invention, a water-powered car! Well, ok, it’s not *technically* my invention. The idea for water-powered cars has been kicking
around for ages. Jules Verne wrote that “water will be the
coal of the future!” way back in 1874… so why aren’t water-powered cars everywhere
yet? And why isn’t mine working PERFECTLY as
I planned? To get to the bottom of this, we need to take
a look at some of history’s more recent attempts to *go* with *h20* The idea became especially popular a century
after Jules Verne’s prediction, during the American oil crises of the 1970s. A prolific inventor named Stanley Mayer patented
a vehicle that he said could drive cross country on only 75 litres of pure water. It was a beautiful vision, but the science
didn’t quite back this idea up, and he ran into some legal trouble because of it. In the late 2000s, the internet was inundated
by simple kits that promised to transform your car into a “water-burning hybrid”
and increase your fuel economy by up to 300 percent. That same year, a company called Genepax began
marketing a water-powered car they claimed was going to save the world from global warming. In the end, though, these prototypes ran into
a teensy-tiny problem: the first law of thermodynamics. Energy cannot be created or destroyed. So what’s the problem here? Well, water on its own is simply not a fuel;
similar to CO2, it’s only the product of a real fuel combusting. But water still carries energy locked up in
its bonds, and Mayer’s invention, like many others, is based on splitting these bonds
in a process called electrolysis. By separating the hydrogen and oxygen molecules
in water, the hydrogen can be used as fuel, and fed back into the engine, or if its an
electric car, the fuel cell. Even better, this consumed hydrogen only produces
water as waste. So vroom vroom, there you go! A super clean zero emissions fuel attached
to zero guilt. Except not really. Because water is very stable, and splitting
it up requires a lot more work than it’s worth, kinda like climbing up a steep slide. Triangle Bob’s having fun though, so that’s
good! Mayer thought he’d figured out an easy way
to do it, with far less energy wasted than a normal electrolytic cell, but what he created
consumed more energy than it produced. Today, after decades of research, the electrolysis
of water has yet to prove itself a viable way to produce hydrogen fuel. And if we can’t get hydrogen fuel from water,
it’s not really clean energy at all. Currently, only four percent of all hydrogen
produced comes from water electrolysis, some of which is generated by renewable electricity. The rest mostly comes from fossil fuels. Still, some scientists are desperate to make
hydrogen energy sustainable, and in recent years, efforts have more than doubled the
efficiency of water electrolysis. In turn, researchers at Stanford claim they’ve
figured out a way to generate hydrogen fuel using solar power and saltwater. So who knows maybe there’ll come a day when
you can just pull over to the side of the road and fuel up on the ocean, but until then,
maybe just try and ride your bike or take the bus as much as you can! Or ride your whale with legs to the local
market and watch everyone scream. Whichever you prefer! So if you could power your car on anything
imaginable, what would it be? Let me know in the comment section below,
or tell me, what should I talk about next. Curious to know why these walls have legs,
check out this video! Perhaps they would look a bit like their other
ancestor, Ambulocetus natans, whose name actually translates to “walking whale that swims. as always my name is Blocko, this has been
life noggin, don’t forget to keep on thinking!

  1. We did have one but a car company buy it and destroyed it. And it is most with money and not most people know how or do not have the money to buy parts for the engine or car.

  2. Well, technically, the idea of water powered cars dosen't seem too far off. It is theoretically possible to make artificial plants that would use photosynthesis to generate electricity (because while energy cannot be created or destroyed, it can change into different forms). That electricity could be used in an electric car, and now you have pretty much infinite fuel.

  3. There was a car that was water powered but the person who made it was poison since it would risk the oil and gas industry

  4. Blocko i would choose air to power cars because if it was an electric car every time you are driving you could have a wind mil that powers the car by turning air into eletric

  5. Also water vapor is orders of magnitude worse of a greenhouse gas than CO2. Yes, we have the watercycle that keeps things in check. Do we really want to mess with that?

  6. Bro why don’t we just have it work by making steam and use it to spin a turbine with a generator to power a electric motor?

  7. Dear Blocko, if the earth was going around the sun 100x faster than the speed of light, how long would a year be?
    PS, you r a good channel keep up the good work

  8. Anything imaginable?
    Feet but not feet
    Got it?
    No, i can't understand it either
    What about…
    WITH I M A G I N A T I O N

  9. There's a reason Elon Musk says that Hydrogen fuel cells are mindbogglingly stupid. Not only do you have to use fossil fuels to make Hydrogen but doing so creates more CO2 and water vapor (the emissions of the hyrogen car) is a worse greenhouse gas than CO2. Why would we want to replace all oir cars with hydrogen cars when electric cars linked to solar, wind, geothermal, Tidal and TBRs would make much more sense.

  10. 1. water powered cars are stupid because were waisting water when we can just use gas
    2. conserver water dont waist it guys

  11. My car will be powered by sound I'll just put my girl inside and then I can go anywhere because she won't stop yapping

  12. Something that gives me the rumble of gasoline but without the emissions. You know what I mean by rumble, right?
