what if we could make a membrane that separated o2 and hydrogen from water. i thought green hydrogen was produced using green power, solar,wind,hydro?
General Motors X-250, Radial 4 (8) Engine | National Air and Space Museum i did read that its easier to balance a odd# of cyl. is that what you mean?
An engine can get 10% to 20% better fuel economy with leaner air fuel mix and slightly advanced timing. Only problem is lean burn engines can't meet US emissions because of the NOx. You'd need a selective reduction catalyst and def fluid like a diesel.
Uses wind solar and hydro to the tune of 50kwh to make 1kg of hydrogen. Then you use that 50kwh worth of hydrogen in a fuel cell and maybe get 20kwh worth of work back out of it. 25kwh if you feed the fuel cell pure oxygen and run it at low load. That's the problem. Even 120 year old lead acid battery tech stomps the shit out of fuel cells in the efficiency department. Only place they did kinda good was stored power to weight. Especially when you have astronauts that already need water and heat, the weight of that hydrogen and oxygen almost doesn't matter at that point.
As long as the wood is free every hour of my labor easily works out to a few mega watt hours or several MMbtu hworth of heat.
keeps you warm 4 times. cutting it down, loading it up, blocking and splitting it, then burning it. been playing that game a while. as i get older i need more tools to do it. my 8lb maul days are over, i see a nice splitter in my future. pound for pound you are right.
I doubt there's such a thing as free energy (just like a free lunch). But I've said for years now, that the next great industrial revolution will come about, once we can achieve room temperature super conduction.....and we're awfully close now. Used to be, to achieve that, you'd have to run the system at temperatures so low, that you'd use far too much energy to achieve it. But as scientists have experimented with different materials, they have achieved super conduction at -135C (at normal atmospheric pressure), and as high as -29C at high pressure. May not sound as though we're that close, but I believe it could happen in the next 20 years. And once super conduction is achieved at or near room temperature, they should be able to achieve fusion reactors that don't need more power going in, than they get out of them.....and we'll soon have that industrial revolution. Because the greatest "green" energy will be taking water (of which we seem to have a plenitude of), and create virtually unlimited power with it. Imagine no more ugly solar "farms", or wind turbines! What will people like Al Gore do then??
thank-you it not if,,,,, its when. "Because the greatest "green" energy will be taking water (of which we seem to have a plenitude of), and create virtually unlimited power with it."
Hydrogen fuel cells are a waste of good energy. My system uses floating barges with solar power to crack the ocean water. The H and O2 are then pumped to shore, compressed, and used in ICE engines as a clean burning fuel. With enough solar, the system will run for free. Another use would be on-board storage and then just dock alongside and transfer the fuel into your hydrogen powered boat. It isn't free due to the investment up from and replacement of electrodes, and it isn't efficient because solar panels still suck at efficiency. In the positive column, it is scalable and a system large enough would see a net gain over initial investment cost.
i think in the next 3 years trump will make a economic investment, business grants or some kind of stimulus. maybe get ready to build one. you will be fighting the oil industry that killed all the previous plans. maybe plan on harvesting chlorine if its in salt water. i found wave/tide generators interesting anchorage has a 14' tide. i was thinking a system like the old clocks to store the energy. tide/waves lifts a weight then uses it for power. a push/pull type thing. wave energy is pretty consistent around bluffs and deep cliffs. it isn't free but constant. i believe it can be done. im more interested in discussing how to make it work instead of why it cant. why it hasn't worked is part of the process of elimination. waves to drive pistons?
Right now, coal, oil and natural gas are cheap. infrastructure is already in place. All other energy sources are going to have to spend decades trying to displace this. Some small nations/regions can easily switch (thinking islands with sunshine) as they probably already are importing their energy supply. The revolution will come when each home has it's own power source that costs the same or is less than the energy supplier they currently have. Until then, we will experiment and have early adopters paving the way and the folks with a natural gas well on their property will just chuckle. Pretty sure we are decades away from mass availability and i'll be long dead.
Problem is you need like 16kg of O to fuel cell 1kg of H. Other problems are the 50kwh needed to make 1kg of hydrogen is only going to power a hydrogen powered fuel cell car 40 to 70 miles according to Toyota. My shitty obsolete Nissan leaf will go 150 miles according to kiras google search with the same amount of electricity. Other problems is hydrogen costs around $21 per kg. 50kwh according to kiras "average person who will own nothing and be happy" costs 17 cents per kWh. That's $8.50 worth of average person electricity. So $8.50 to go between 150 and 200 miles with electricity or $20+ for 40 to 70 miles with hydrogen.
we lost the coal export contract to south korea, im not sure why. cheaper/closer? they would mine it in healy then train to seward and load huge ships with it. the loading belt is still here but there is talk of scrapping it. i could get it for 80$ a ton here but the union loader assholes would pick the powder over the chunks every time. to get burnable chunks id have to go to healy/palmer. i still have a tote full but its 80% powder. i tried saving cereal/cracker boxs and filling them with the powder but it does not work well,, even in a coal stove you need chunks or it just falls through the grate. making bricks is labor intensive. on a industrial scale they grind coal to powder then aresolize it into a burning chamber, not easy to replicate on small scale. there was a 1/2 mile long pile 60' high they would take a few weeks to build up then load on the ship. some folks bitched about the coal dust but i dont think that shut it down. i would point to a nice pile of big chunks and they would laugh and pick the powder every time. palmer 130 miles away has 50# bags of chunk coal 8.50 or 210 a ton. its nice to throw some big chunks in before bed and have hot coals to start the fire with. it does smell some to burn it. il prob get a few more totes if the p/u runs. my wood stove now will burn coal chunks. might be worth a dump truck load,,, if i got usable stuff.
so fuel cells suck, got it. how does it compare to running hydrogen in a i.c.e? yes it would have to be done at scale to reduce cost.
,,,, you mean its expensive to run now because we dont have plentiful hydrogen sources. maybe we can change that. no oxides of nitrus, no co. seems like its worth considering. if both the clintons were publicly hung id wait till the video showed up on odessy, bitchute, rumble, ect. to watch it. i know. more proof im nuts. i dont do facebook. i wont watch a tiktok or youtube regardless of content. they are not the library of Alexandria.
If you didn't watch the video, then here is the gist. 1 gallon of gasoline has just an ever so slightly higher energy density than one Kg of hydrogen. and burning in an internal combustion engine will give you about the same miles range per gal/kg. So, Gasoline 3.50 a gallon. Hydrogen 20 to a kg. running it in an ICE engine won't make sense until gasoline is over 10 bucks a gallon and hydrogen is under that. For now, hydrogen is way better off in a fuel celled application.
I want a fuel cell standby generator that can strip off the carbon from natural gas and use the hydrogen. We got a shit ton of natural gas. Now that would be something I might buy before it goes mainstream.
