@geor664 Actually, I looked it up on their website, they do inject oil, but not into the main chamber, only spot lubrication on the seals themselves. So the LiquidPiston rotary engines actually don't need more oil then a regular piston engine. I love the idea of all the flexibility of a hybrid car with this engine. You could produce hydrogen at home to fuel it as well as charge its batteries at home, then switch to gasoline when on long road trips if needed, or biodiesel or all sort of other fuels, and if there's a huge cataclysm and society ends or whatever you'd have several possible ways of powering your vehicle. =)

@tkorte101 Yes, they need CO2, that's the whole point. There's too much CO2 in the air, so the trees are meant to be planted to convert the excess CO2 in the air into wood. Most of the CO2 in the air right now has been locked away in coal and other long and usually slow carbon cycles for millions of years, but we've fast tracked their emissions without fast tracking their absorption back on the other end of the carbon cycle.

@The_Chad_Davis There's actually quite a few more evidences then just those gas bubbles in the ice, although they are a important clue. Climate scientists are of course using multiple sources of data.

@Jv19979 Actually, vulcanoes emitt about 200 million tons of CO2 every year, humans do 24 billion tons every year. We're releasing far more CO2 then all the vulcanoes on earth does right now.

@flashg1160 This is about statistics. Yes, there's been bad storms in the past and there will be bad ones in the future. But there's more of them and on average worse ones comming. And worse ones have arrived.

@tkorte101 Critically low CO2 levels? Where the heck did you get that idea from? -_- You can test the CO2 levels yourself, they're high. Yes, there will be a day when we'll run out of carbon on our planet, but that's gong to be billions of years into the future, approaching the time when our planet will be swallowed by the sun anyway... And yes, if you go back far enough in the fossile records there wasn't exactly much CO2 in the air back in the days when most of our coal was actually created as most of it was bound in the forests that became our current coal deposits, where a lot of that carbon has been locked away ever since, thankfully.

@tkorte101 It's happening. The reason why carbonated water is acidic is because the bubbles in carbonated water is literally CO2. And every single gas in the air gets trapped in air bubbles that gets mixed in with the sea water naturally due to waves etc. I'm sure you've seen them, waves, right? As for the "how things used to be like" idea... Yes, there's been a lot of different eras on our planets history, including several that humans would never be able to survive in... Several where we quite literally wouldn't be able to breath. And no, plants are not carbon starved at all... We've also had periods with way less carbon in the air even then to prior to us humans showing up.

@Jade_Bronson Um, I think you're missing the whole this is a different design from those that had all the problems in the past thing... This isn't a engine with even half the issues that rotary engines of the past has had.

@christopherbrown6523 Creating new fuel really isn't the point. Even if it's synthetic it's still going to release emmissions that's just not acceptable long term. ICE is on its way out. More then half of all cars being sold here in Norway has been electric for several years now.

@fliporhold No, there's more glacier melt now then there was. Yes, there are places where there's more growth and some individual places it's about even, but on the whole around the globe they're retreating at an alarming rate. I've been to several of said glaciers, both here in Norway and when visiting family members in Iceland, the difference is quite staggering. Also, I have family members over in Greenland who have shared pictures from their home villages over on Greenland and the glaciers there... Trust me, they're melting fast...

@Jv19979 Removing carbon from the air is a energy intensive process, it's not really viable to do in a non-biological way yet, and even if it became viable you'd need a lot of energy to do anything like that. I can gurantee that it's not going to be the fuel of the future. ICE is on its way out. As for carbon never going away... As a fuel, most definitively it will. In the air... No, not for billions of years yet... But eventually the planet will lose its magnetic field and therefore also its atmosphere and its carbon...

@highclasswhitetrash9027 Yep, but for me it's powering these things from home made hydrogen while still having the option of other fuel types when needed that's appealing. And of course I'd like it to be a plug in hybrid if I'm even to consider it. I'd be running on electricity the wast majority of the time. Hydrogen, diesel etc would all be backups for the battery for me for situations where more engine power or range or both is needed.
2
How does that thing work with A) hydrogen and B) hydrogen + gasolin mix? I'd love to have a hybrid car that can run either on electricity (plug in), gasolin, hydrogen (made at home from fresh water and electricity) and ideally also diesel, just for the ultimate in flexibility. Possibly using a neural network and sensors to adjust things as needed. And ideally being able to fill up different fuel types whenever I like without worrying about the details when changing fuel.

@ZeroCooly Not sure if you've noticed, but the bottom of the sea has quite a lot of pressure, water after all is rather heavy... And air is absorbed into the water by the waves... So, air bubbles in the water that's being pulled down by the currents down to the bottom of the sea... Yeah, your argument isn't really holding water as far as I can tell...
1
@highclasswhitetrash9027 You don't really need to be smart... You'd essentially just buy a box, connect water and electricity on one end and you'd get oxygen and hydrogen on the other end. It won't even have moving parts, although it will wear out eventually due to chemical processes that can't be controlled just like a battery will...

@heinzmaier2739 So, you're wondereing why the water isn't lowering? Melting fresh water from all the various land based ice is part of it. And there's many other cycles involved, like how much water is in the atmosphere vs in the form of fluid in the sea and lakes etc vs water that's literally in the ground. Huge amounts of the Earths water is most likely not at the surface at all but in the mantle etc. Only about 0,3% of the surface water is actually available to us humans as drinking water. So even with the water inside us that is still so little that it makes little impact on the sea levels, our carbon emissions however has more impact and is visible.

@Rainer Kinzinger Theoretically yes, you'd get more weed, although you wouldn't necessarily get as stoned on that weed. I don't have experience with weed in particular. But I know that with vegetables we here in Norway sell vegetables and fruit that often taste better then many other places because our climate makes them grow slower increasing the concentration of a lot of things in those plants, while the faster growing ones elsewhere is mostly just water and carbon and little else leaving them somewhat tasteless by comparison. This doesn't apply to all plants, but it does to some of them. But regardless, if you want to increase yield then there's better ways to do so then to increase the carbon levels in the whole atmosphere... You could just do it in a greenhouse with local carbon levels that's higher, you'd need way less carbon to do so and get that effect there and you wouldn't fuck up our enviroment doing it...

@Jade_Bronson Um, what comment where that replying to if I may ask? There's a rotary engine out there that doesn't have lubrication issues by the way.
1
@ivan schafeldt There's more then one type. And sure, any individual reading needs to be taken with a grain of salt... But when you start adding up thousands of them you got another story.
1
@Petri_Pennala Depends, our coal is mostly trees, but some of this stuff predates trees by quite a bit...

@resuwrecked Liquid Pisons design uses stationary seals so you get a tighter fit and since they're stationary you can lubricate on the point instead of adding the lubrication to the fuel, so you get about as much lubrication as with a regular piston engine. As for hydrogen and electricity being coal powered. That of course depends on the electricity makeup in any given location. But even if you use 100% coal power to fuel a EV it's still more enviromentally friendly then a gasoline engine just a few months after purchase assuming you use both equally and regularly. Now granted in a location with a non-renewable electricity mix a plug in hybrid is the most enviromentally friendly due to the lower carbon impact of a smaller battery and the reduced carbon saving of charging compared to a renewable energy source while a electric car require a much bigger battery then a hybrid. The exact math on what's best for the enviroment is kind of complex and depends on the amount you drive as well as the exact electricity composition in a location. But the thing is, having either a EV or a hydrogen car means that at least it is possible for your vehicle to make the switch to 100% renewable if 100% renewable power is made available to you, with a gasolin engine that's not the case.
1
@theviniso No, it doesn't. With stationary seals you can inject lubrication where it is needed rather then to mix it into the oil itself and there's less wear and tear on the seals. This design should require less maintainance, use less fuel consumption and especially need less oil for lubrication. Is it perfect? No. But it's a good step in the right direction. I'd love to have a plug in hybrid using a engine like this capable of both using gasoline and potentially renewable fuels like hydrogen.

@dhc2 There's been emission standards for factories since the 1860s or so in Britain and other countries followed. (The first enviromental act in Britain was actually a short lived ban on coal fires in London in 1306, but the Alkali Act of 1863 is the oldest ban on pollution from factories that I can see on the books anywhere... Regulation on factory emissions therefore has a long story, the difference here is just that for once we private citizens actually are asked to make changes to our lives and regulations are made to facilitate and incentivise that...
1
@Twilzeth Nope, you're thinking of the Wankel engine that indeed does have those constrains. But this design has fixed places for the seals so the lubrication can be delivered on point just like in a piston engine and doesn't have to be mixed into the fuel itself, reducing the lubrication needs.
1
@smh9902 I'd love to hear about them. =) Especially if they're multi-fuel capable. Ideally also at a low RPM unlike the turbine engines...
1
@catchnkill Any part of the engine that requires lubrication that is stationary can have point lubrication where the lubrication is feed directly to the point in question, that wasn't possible with the Wankel engine.

@gabrielbrunser6401 Please don't resort to name calling. Whatever we might personally think about those we argue against we achieve nothing but the opposite of our goals by resorting to such measures.
1
@stlgdroidst Kind of true. Thankfully we've been blessed with a unusually stable sun with very low variation in output compared to most stars of both its own class and other classes. And we can indeed see the impact of changes in solar activity on the gasses in our atmosphere, for instance how high our amosphere goes depends on that activity with it sometimes puffing out more. However as far as surface level effects that CO2 does matter, not just because of the direct effect, but also the indirect effect through other feedback loops. Look up the video that Simon Clark made about why Venus is so cold.
1
@stlgdroidst Also, for reference Venus is further away from the Sun then Mercury, yet it's way hotter at the surface. And the moon is the same distance from the Sun as the Earth but it's not the same temperature, not even close. Indeed greenhouse gases are indeed the reason we don't live on a ice rock with similar temperatures to Mars right now, but while having some greenhouse gases is a blessing there's such a thing has having too much of a good thing.
1
@Muck006 Even running a EV on 100% coal powered electricity using batteries that produce quite a bit of greenhouse gasses to produce you still end up producing less CO2 with a EV then with a gasoline car after just a few months to a year of use assuming daily driving with both. But yes, you're right, technically in places with a low rate of renewable power in the energy mix a plug in hybrid car (with a big enough battery for your daily driving) is actually more enviromentally friendly then a pure EV, you need a certain amount of renewable energy in the energy mix for a pure EV to make more sense then a plug in hybrid enviromentally speaking.
1
@Muck006 Some of us actually have a decent amount of renewable energy in our energy grid, but even in a 100% coal powered place a EV is still more enviromentally friendly then a gasoline car. As for the whole why not using technology thing... Because technology is a important part of modern life? The impact of using a computer or a EV is relatively low compared to using a ICE car etc. There's diminishing returns for these things. Someone doing a lot of harm arguing that those who do the least amount of harm should stop doing any harm when they complain about those doing the most harm doing a lot of harm is kind of a strawman argument to be honest I feel... I've changed several of my own life choices to reduce my own emissions. Public transport, vegetarian diet, locally sourced products etc... And in my own country our electricity mix is mostly hydropower, so almost entierly renewable assuming that the weather paterns don't change too much and we keep getting water into the reservoars we use to produce our electricity... Could I do better? Probably, personally I can't afford to build a new house that's passivly heated though, so I do the next best thing, and live in a appartment complex with multiple homes, so the heat in each apartment is shared to some degree with the rest... And yes, I afford myself the luxury of using our mostly renewable electricity and using technology that granted does produce emissions on the point of production but is relatively enviromentally friendly when kept, especially since said computer is my main source of heat in my appartment...
