Convert Coal Power Plants to Hydrogen is a way of re-purposing existing infrastructure to quickly switch our existing electrical grids to renewable energy.
And here in California: “Hydrogen is the most abundant element in the universe, but just coming into its own as a versatile fuel for a world moving away from hydrocarbons. Capturing hydrogen is simple in theory: just apply a lot of energy to water to break the two H’s (hydrogen) from the O (oxygen) to create pure hydrogen. Like natural gas, that hydrogen contains heat that can be released with combustion to drive a generator. Unlike natural gas, that combustion is GHG-free.”

No, Thermodynamics Does Not Explain Our Perceived Arrow Of Time
Bet they didn’t realise at the time that the idea of the second law was what gives time a forward only direction. ie…”Entropy is one of the few quantities in the physical sciences that require a particular direction for time, sometimes called an arrow of time. As one goes “forward” in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease.”

Professor Mike Merrifield does a good job of explaining what this idea entails. The second law is the interesting one though, because it has various formulations as it was thought up before people understood entropy. Yes you need to add energy to a system in order to make colder things hotter. With regards to entropy, Lord Kelvin states that you can’t turn heat directly into useful energy. Seems obvious really but its an idea that has stood the test of time and likely won’t be disproven.

With this chair, you will always look forward to a day in the office.
Something perfect for a home office
Here’s to redefining the phrase “sleeping on the job.”
LPG fuel is an excellent alternative to petrol and diesel. Some people have safety concerns, but as this video shows, proper conversion of your can prevent this. https://www.youtube.com/watch?v=AG4JwbK3-q0
You don’t have to even buy an autogas car. You can have your car converted to run on LPG. Check out the conversion process here. https://www.youtube.com/watch?v=hxlzPyztWCI
Using LGP as fuel sounds incredible and has several benefits over petrol and diesel fuels. The gas is cheaper, the engines run silent, and the gas emits less CO2 into the air. Check out this article on the benefits of autogas. https://www.begasmotor.com/what-is-lpg-autogas-what-advantages-does-it-have-frequent-questions/
There are negative impacts on nature but these can be negated if thought about properly. This article details a few pointers for sustainable future development.
Lol, nice pic, though the wind isn’t the only problem on the Sussex coast. Got to say that the Rampion wind farm seems to be a total success. Read more about it here as these giant saviours are likely coming to your location too, soon.
Wind speeds of 122mph at the Needles on the Isle of Wight are provisionally the highest gust ever recorded in England, the Met Office said.
There are portable solar-powered car AC coolers that you can buy! Check out one here https://www.amazon.com/MASO-Powered-Exhaust-Radiator-Purifiers/dp/B07TXH7HMP
Check out this DIY solar-powered AC unit. The system is quite cumbersome, but a great idea nonetheless. https://www.youtube.com/watch?v=BL74J9X6Das
Solar-powered air conditioning is a gamechanger as it means you can keep your car cool without running the risk of draining the battery during an idle park.
Yeah, they are pretty common now – and a good thing. Motor boats suck, compared to using wind or the sun. Good stuff, loving this article here. https://robbreport.com/motors/marine/solar-powered-yachts-mainstream-oddball-niche-1234592000/
They are the future. Imagine solar power container ships.
You can actually buy solar powered yachts as well as speedboats now. Cool idea.
You can purchase them! There is a company selling water-cooled LED grow lights, which reduce the heat dumped in the growing space. This means a longer lifespan for your grow lights while reducing the costs needed for AC infrastructure.
True. Liquid cooling can help dissipate heat more efficiently in LED lights, making them last longer. It can also allow for greater light output, meaning brighter lights
Amazing idea. There are already companies that are researching how to use liquid cooling technology in LED lights
Same. interchangeable means the same in a way.
Gravity isn’t what you think though.
Matter is just stored energy that makes time go slower
(3 upvotes)Gravity is just time curving into space
(3 upvotes)Hard to find a definitive answer according to this https://www.askamathematician.com/2010/01/q-is-it-true-that-all-matter-is-simply-condensed-energy/
Matter isn’t stored energy but t does have energy, called “rest energy.” What distinguishes matter-energy from other forms of energy is that all matter has inertia and is subject to the force of gravity when at rest as well as when in motion.
For reference: https://www.nasa.gov/mission_pages/tdm/fission-surface-power/index.html
“INSANE” idea according to Cosmos lab – lol, the fools.
NASA are looking into this idea already. Read this…
How come there are articles and videos online that claim that electrons are subatomic particles – the web was invented decades after we realized they weren’t. Anyways, they are still our best little friends. Arvin does a good job of explaining them here.
Never heard of them before but they get a mention and an answer on Chegg.
Not sure about “bold” but electrons are still a long way from being understood, despite us using them all the time.
“Not only can today’s technologies cut elevators’ energy use, but they also can return energy to the building grid.”
Breaking is broken, from lifts to electric trains, cars to pushbikes, applying breaks is simply swapping useful energy for bad useless energy, ie entropy. So it goes!
Not new, a but cool idea.
Loving these magnetic elevators- that can go sideways too like a tube.
Possibly – AEVs are far more efficient than conventional gas-powered vehicles: AEV batteries convert 59 to 62 percent of energy into vehicle movement while gas powered vehicles only convert between 17 and 21 percent.
Cool, I found this vid But won’t electric engines replace them sooner rather than later?
Whoever had this idea first will change a bit of history. Early days though now… “The lean-burn, compression ignition (CI), direct injection (DI), is the most efficient internal combustion engine (ICE) (Zhao, 2009; Mollenhauer and Tschöke, 2010). It produces engine-out emissions of nitrous oxides and particulate matter (PM) that need after treatment to match the extremely low limits set up for transport applications (Lloyd and Cackette, 2001; Burtscher, 2005; Maricq, 2007)”
This would revolutionise things if it works and is cheap enough – not just on building roofs but on cars too.
should be a thing already – more info here
This looks better “Quantum dots, also known as photovoltaic paint, were developed at the University of Toronto. They are nanoscale semiconductors that can capture light and turn it into an electric current.”
This stuff could be great for irregular shaped buildings that want to catch some rays.
cough… they call it “green hydrogen” (?) they should tell scientists that all of the elements now have colors.
Ohio too 😉 https://www.oceangeothermal.org/convert-coal-power-plants-to-hydrogen/
And here in California: “Hydrogen is the most abundant element in the universe, but just coming into its own as a versatile fuel for a world moving away from hydrocarbons. Capturing hydrogen is simple in theory: just apply a lot of energy to water to break the two H’s (hydrogen) from the O (oxygen) to create pure hydrogen. Like natural gas, that hydrogen contains heat that can be released with combustion to drive a generator. Unlike natural gas, that combustion is GHG-free.”
…. and make your own! watch this ….
Great idea and it is actually starting to happen! Escalante H2 Power states this will be the world’s first conversion from a large-scale CFPP to a large-scale blue/green hydrogen fired zero-emission power plant.
Thought this was a joke. Doesn’t look pretty and if you don’t have enough poo, just plug in to the regular supply. Bit odd to be honest.
The french don’t poo in the street as many claim, but I guess this could work for human waste too. There are toilets near public parks, maybe this could be a breakthrough.
Goodness, it’s a thing. This could get legs!
Everybody, meet Mike and his hydrogen house.
Our brains certainly are! You have got to read this to get the bigger picture https://www.sciencealert.com/human-consciousness-could-be-a-result-of-entropy-study-science
That’s one way of looking at it. and yes, there is only one way to go. Forward Christian soldiers, to our destiny!
Adding the video as a link – why doesn’t IdeaMill do previews when you add links to the idea description too?
Not sure why Musk is against them though,,,, lol.
There seems to be 2 options, fuel for the engine or fuel to power the electric motor. Either would be better than dirty diesel.
Been waiting for this for years, not sure if it will happen though, despite there being plenty of free hydrogen about.
“Fossil fuels were the right combination of plentiful and relatively cheap to dominate the energy market for decades.” not any more!
could be more efficient than burning gas. Imaging that.
read about this here…
Theoretical physics means you invent answers and spend your life looking for them. Ironically it works better than the old way of waiting to find something when you don’t know what you are looking for.
“give up and let theorists just tell their stories?” lol, sounds about right.
“To date, no evidence for supersymmetry has been found, and experiments at the Large Hadron Collider have ruled out the simplest supersymmetric models.” Just sayin’
Glad it appears on ideamill – ITS JUST AN IDEA, NOT A THING, watch this.
We are only here discussing the idea of the Sun’s gender because it does so well at providing us the perfect environment for us to live and prosper. However, The solar genitals are not what matter, nor how (s)he identifies. Because regardless of its sexuality THE SUN WILL SPAWN OFFSPRING, and had parents – which is all that matters. Is he or she trans or gay or both? Or are we just doing the usual human thing of applying our ideas to the wrong things?
Lol, thanks for spending our money wisely NASA “We’ve been working on this ever since Neil Armstrong found out the Moon was a boy back in ‘69” said Dr. Andrew Chapner of NASA’s Star Gender division. “And look, we know it’s not our business how the Sun identifies but we just have to know.”
For most Sol is a female (word) for the Germans, not so. But I get your point, it protects and nourishes us, so a bit of both.
CONGRATULATIONS! IT’S A GIRL!
Bosch tried this in 2016. Never used one so dunno if it is any good.
Aha, they are called active gas pedals. As long as they allow you to accelerate out of trouble then why not?
Looks like there is a patent for this, probably doesn’t need AI though.
Now the petrochemical industry scammers have been knocked off the rich-list the options are going to open right up. The future is waiting for us to embrace it. Finally.
Hydrogen is the answer, just need Musk to realise it.
I agree, until electricity is made greenly you are better off using one of the other alternatives to gas. Here is a decent list of options https://fortune.com/2013/11/01/10-alternatives-to-the-gasoline-powered-engine/
This could actually work, kind of like the opposite to the vertical fans you get for the office.
How about something like this, seen on Wikipedia https://en.wikipedia.org/wiki/Vertical_axis_wind_turbine#/media/File:Light_pole_wind_turbine.gif
These are on their way I am sure of it. Although not cylindrical as such, the Japanese have invented vertical ones that would fit in cities.
“Science” can do that already. This idea will develop and hopefully turn a full circle so we can put that dirty black crap back underground where it belongs. The Sun was created to provide our energy, didn’t you know?
Instructables explain how you can turn it into fuel – not an excuse for all the extra placcy bags we make and waste though. Nice to know this is possible already.
It’s early days but the Dutch company PyrOil developed a method to turn plastic back into oil in a continuous stream using pyrolysis.
looks like a particle to me. I think it is a particle and a wave. So do most that read physics.
Think these rolls are only available to trade. As I can’t see anything like a rollout matt on amazon or ebay.
These are a great idea, you can just roll them out on top of your camper or anywhere. Not sure which is the best but there are a few options already available. Flexible, though not purely roll-out.
This exists already, though I don’t think you can buy them anywhere soon.
What about this little beauty. Visualises the infosphere for you.
This would be amazing, but you would need to move a slider to tell it which frequency you want otherwise it would be a confusing mess. Watch this. I want one, someone should make the sensor and app.
This! But nothing on the app store that lets you point here and there to see whats going past, or through your brain. Ie microwaves, radio waves etc.
Thought I had found one online then but this thing just identifies the source of the radiation.
Thank goodness, wouldn’t want 4×10^84 photons tickling my brain.
Aptly named book about science that ‘stares you in the face’.
IS the Universe a closed system? How could you disprove that it isn’t? Too many assumptions in order to KNOW the second law is ALWAYS right (for me).
Time will tell….. “Physicists at the University of Zurich have developed a deceptively simple device that allows heat to flow temporarily from a cold object to a warm object without an external power supply.”
Don’t hold your breath. If this new theory pans out, quantum demons might someday power our air conditioners and refrigerators, saving you electricity and cheating the current laws of physics at the same time.
nice idea, but the jury is still out on if it is the reason time goes one way only, everything else points to it being able to go both ways, just not for urr, us.
Bet they didn’t realise at the time that the idea of the second law was what gives time a forward only direction. ie…”Entropy is one of the few quantities in the physical sciences that require a particular direction for time, sometimes called an arrow of time. As one goes “forward” in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease.”
Professor Mike Merrifield does a good job of explaining what this idea entails. The second law is the interesting one though, because it has various formulations as it was thought up before people understood entropy. Yes you need to add energy to a system in order to make colder things hotter. With regards to entropy, Lord Kelvin states that you can’t turn heat directly into useful energy. Seems obvious really but its an idea that has stood the test of time and likely won’t be disproven.
Saw this idea on the amazing Half-Bakery site, which lists crap ideas, and I highly recommend. Someone on there says Eddison had a front door genny.
Works just as well on normal doors, not sure if they would be that efficient though.
Been invented, just not implemented everywhere yet.
Range and re-charge time are always going to be a problem with lecky motorbikes. Not quite nailed it yet.
Get with the program man, there are heaps of them out there already, some are just amazing.
Could work for cold environments, but for keeping factories cool, some buildings use seawater to save money.
Often thought of this but have read here and elsewhere that it just moves the problem by causing inefficient pressure build up.
Says here they are in use already – “The famous ‘Van Gogh Village’ uses Tvilight CitySense”
Old idea, but yeah, LED lights would work well for this.
Not sure if this is still the case but it took 20 minutes to get street lamps to light up efficiently, maybe that has changed with LEDs?
Nitrogen no, but the age of Hydrogen-powered flight and spaceflight is dawning.
this nitrogen idea keeps coming round, I don’t like it. here’s why:
just wow!
Sci Show Rocks
Dr. Michelle Thaller was wrong in this video, lots of the hydrogen in our bodies was born before there were stars. But the video is good.
Forget Jesus, the STARS died so you could be here today!
(7 upvotes)You eat dead stars for breakfast
(11 upvotes)… and everything in your body (up to iron in the periodic table) was made in a star, everything in your body beyond iron was made in a supernova – we really are “star-stuff”, Bon appetit.
You don’t need to pull them to the bottom, just fill them up and pressure gives you the power back whenever you want it. Amazing idea tbh.
Notts Uni guys are working on this still I think. https://www.youtube.com/watch?v=ktup6CAvfGo
Not as silly as it sounds, check this in Toronto https://www.youtube.com/watch?v=GicQwXbNnv0
Or at work…
No reason why this idea won’t work – self heating pools are go!
They only use them to heat pools at the moment – someone should put 2 and 2 together.
Hyundai nailed it for cars already, but yeah, trucks, trains, planes etc.
This looks amazing.
You can get them already at https://www.trailar.co.uk/
Ahh but can it spot the culprits of light seen from the ground also? Lots of people now worried the night sky is being ruined by SpaceX.
NASA already have the data – There’s no hiding now.
Good article here, its not just a problem for astronomers.
Going “off grid” needs to be an option for future generations, we should make sure we get it up and running for our kids. Its happening, but very slowly. Big money is holding it back as usual. Read this https://www.power-technology.com/features/can-the-uk-ever-achieve-a-fully-decentralised-energy-system/
This was a good idea and is now starting to be a good thing. Nice call.
Brian made one of these, I think you can buy them on his site too https://theepicenter.com/
it exists, i have one, they work really well for stuff like charging phones – not sure if you can power proper lights and stuff though.
On their way already, better is they detect your phone so you get personalised ads.
Giving a name to something you don’t know is there is a risky business, people will believe it before it has been observed. Is this idea based on science or something else?
Entropictastic! “Dark energy could be merely mimicking the cosmological constant, a scalar field changing so slowly that we have not yet been able to detect it. Or (whisper it quietly) perhaps dark energy does not even exist.”
These on amazon, loads of options nowadays
Not sure where you buy this but it looks better than just a tent…
you cna get them already, expensive though
An attractive idea, its a sucker for sure…
Great idea, but nobody knows why gravity only sucks, see the new scientist article here https://www.newscientist.com/article/mg20227122-800-gravity-mysteries-why-does-gravity-only-pull/
Heres the video, I want one!
Solar powered tents look great
Early days. Won’t be a while til someone makes an industrial sized version to save factory energy costs.
Not only that but they may one day know WHO is watching them – if Facebook allow your data to be sold/stolen, or whatever they call it.
There are heaps fo applications for sterling engines, I guess they may become commonplace in building and floating on the sea to capture the difference in temperature between the water and air.
