Quote from: K-Dog on May 07, 2024, 01:15 AMThe truth about hydrogen has been known for quite a while.  But.............

Definitely it has its deficiencies.  Vehicles will need to be designed with much larger fuel tanks and will have less range and performance.  The H-ICE variation really is only useful for heavy equipment where you need the torque.  In automobiles, going electric with a fuel cell makes much more sense.  As a fuel for aviation it looks close to useless, except of course if Hindenburgh-phobia can be overcome and we bring back dirigibles.  :)

However, IF enough of the necessary infrastructure could be built for the distribution and IF enough renewable energy production facilities making Green Hydrogen came online and IF enough affordable cars running either on traditional Li-I batts or H fuel cells could be built by say 2050,  then there is a SLIM hope that we can keep the dieoff down to maybe just 50% of the population rather than 95% and have a technofuturistic utopia instead of becoming stone age hunter gatherers after the collapse.  ;D

Think positive!

Think positive??  You still have not figured out where you are going to get the free juice for making hydrogen.  And when you find your free energy source remember 20% of your power is lost in conversion.  50% if you make it yourself.  But that won't matter because you found free energy.

Robots who mine asteroids for metals can bring some hydrogen back from space too.  The sun is made of it.  A big  spaceship can land on the sun and get some.  We can call her the Solar Express.


Wherever you find your energy source you can use the empty space to sequester CO2.  It the math equations don't balance take psychedelics until it does not matter, when 2 + 2 = 5 you will be in the sweet spot.

And if you solve the technical problems and have your holy dispensation to violate the laws of the universe, inquiring minds would like to know how capitalism which is only a reactionary political force that responds to 'markets' can do the mojo.  Capitalism is incapable of pulling itself up by its bootstraps to create a market where one does not exist.

I suppose the conventional way of developing all this on the public dime, and then giving it to a billionaire for a song or for free. (Russian oligarch style.) could do it.

Hydrogen is a thought-stopper.  Hydrogen tech exists so you don't pay attention and for no other reason.  I say that with confidence because Hydrogen is only a transport mechanism like the wires on a power pole.  Hydrogen is not a source of energy.  You cannot make an energy source because it always takes more energy to make an energy source than you get from using it.  This is a law of the universe and you can't dance around it.

You have to find pure hydrogen for it to be an energy source.  The nearest source of hydrogen is 93 million miles away down a deep gravity well.  Imagining hydrogen as the power of the future is every bit as deluded as thinking you can collect the CO2 in the air and turn it back into gasoline.

Clean CO2, the power of the future.

Scientists at Dreamland University have found a way to turn CO2 in the atmosphere into methane.  This makes CO2 the new freedom molecule.  How is this done?  Professor John Legpuller and his team have ...

Same equation different numbers.
