That is more than enough reason for them to all join in. If you competitor is charging 45% less than you and making more proffit.. you are either going to follow quickly or go out of business. I can see a lot of Arab oil producers trying to stop this by discounting the cost of fuel. I know ships can run on pure unprocessed Venezuelan crude oil which deposits out vanadium metal sufficient to block the ships flues' the engineers have to daily climb up the inside of the chimney stacks with sledge hammers to break the metal out from inside the pipes by smacking the pipes with the hammers to make it drop down into the chimney sump to be removed. The amount of pollutants going through the flue is horrible. Why this was ever allowed I do not know.

the problem is that US doesn't= have what other Countries have. Concentrated areas of people that have been trained in mfg. Modernized ports and infrastructure. the last President didn't get an infrastructure Bill passed and we simply can't ramp up mfg. for large scale production in a short time frame with qualified and trained people. Kids coming out of high school don't want to work for a mass scale mfg. at low wages. People from China, Viet Nam, India and other Countries are willing to do the work. It requires lots of discipline which the US lacks. We have too many lazy spoiled brats. to be quite honest with you.

Energy Observer electrolzes water to run the hydrogen fuel cell: efficiency of electrolyzing water about 70-80%, efficiency of fuel cell about 30-55%. So, overall process efficiency 0.70 x 0.30 up to 0.80 x 0.55 is 21-44%. Efficiency of Li ion battery: 95+%. So why not charge your batteries instead of electrolyzing water to feed your fuel cell? And I didn't add in the energy cost of compressing the hydrogen.

@@richardpark3054 A factor against charging Li+ cells is longevity and sustainability. After ~500 cycles their capacity drops precipitously and they become a fire hazard. No doubt they offer performance in specific applications, but are ill-suited to deep cycle for years on a ship. I don't know Energy Observer's rationale behind using electrolysis and fuel cell, but they most likely use it as a proof of concept. If moving freight was their goal they'd use a LFP battery that'd provide superior energy conversion than electrolysis/H2, as you say.

60+ years ago there was a cargo/passenger ship that emitted ZERO greenhouse gasses in operation. The NS Savannah failed, not because of her technology, but because the operators couldn't/wouldn't decide on how to use her. Build a Panamax sized ship with that technology and it would have probably 50% again the cargo capacity of a "traditional Panamax simply because of needing to carry a fraction of the amount of fuel. And that would be for emergency generators.

The tech requires more energy to manufacture it and replace it every few decades than it saves over the course of it's usable lifetime. This saves money for the shipping company, but it created a whole new manufacturing industry that's pumping pollution out just to keep up with the new demand for this new tech. The same problem is happening with wind turbine farms. It's a net negative. Plus, companies just turn to China for the cheapest version of whatever new tech they need, and that nation doesn't even pretend to try to end pollution.

No, it's not well done, because the new tech caused a new demand. A whole new manufacturing industry is popping up to keep up with the demand for that new tech, and they spend more energy manufacturing the new tech than the new tech can produce over the course of its usable lifetime. It's the same story with wind turbine energy farms. They have to be replaced every 2-3 decades due to wear and tear on the larger parts and safety concerns, just like an airplane engine. We've seen (at least with wind turbines) that the cost eventually causes companies to start acquiring the tech for cheap from Chinese manufacturers, which don't use renewable sources of energy. Until manufacturing gets sorted out, pumping out new tech for transportation can only make things worse.

Wings and sails are NOT ‘sucked’ upwards nor forwards. The low pressure area causes higher pressure air beyond this effect to accelerate towards the low pressure zone and by the time it gets there, the wing or sail has moved on. The result is a THRUST of accelerated air perpendicular to the chord of the sail or wing. IN a wing, this air is thrust DOWNWARDS, and when the thrust of this air matches or exceeds the mass of the plane the wing will fly. On the underside of the Wing or sail, air is compressed to a higher pressure, and can;t pass thru the wing or sail to the low pressure on the other side, so it expands, moving away from the wing. This adds a small component of thrust from the air coming off the trialing edge of the wing. You can tell that THIS is what is at work because Propellors, and Fans all produce a THRUST- not a suction. “Lift” is an imaginary force that resulted from the Wright bros early wind tunnel tests that were quantifying how strongly an airfoil ‘lifted’ on a spring scale.
@kulkrafts3143
@kulkrafts3143 4 ай бұрын
Low pressure vs high pressure as in Bernoulli effect is considered not scientific. If it is a vector changing thrust then it is correct, but your description is confusing. Check MIT basic wing lift lecture online.
@christopherpardell4418
@christopherpardell4418 4 ай бұрын
@@kulkrafts3143 The Bernoulli effect is not generally the cause, because air does not accelerate over the top of the wing. So it is not the increasing speed of the air over the wing that causes the drop in pressure. It is the Angle of Attack. The air going over the wing literally has to fill a larger area because the leading edge of the wing is higher than the trailing edge. As long as the airflow remains laminar, it’s the same amount of molecules filling a larger volume, and that causes a low pressure zone to form. But again, This causes ambient pressure air above this zone to accelerate Into the low pressure zone. The net result is NOT ‘suction’ nor any force of ‘lift’, the result is a flow of air downwards toward the wing, as the wing moves out of the way of the air movement. One of the disconnects is in studying airfoils in a wind tunnel, which creates a stream of air with high inertia. In reality, it is the wing that has high inertia and the relatively still air that has low inertia. Wind tunnels do not adequately show the real physics. But you CAN find photos online of aircraft flying just above a flat, smooth deck of clouds, and see the massive trench the downdraft from the passing wing creates. And, again, you can look at ANY electric fan, or propellor on a plane, and observe directly practically no ‘sucking’ on the top side, but a massive Thrust on the underside of the airfoils. Wings and sails create thrust.

Nice pipe dream , now show me how fast it sails with 5,000 tons of freight . Ive been a sailor and Capt. over 45 years, this is more of a liability on a ship that is purpose built to be a freighter. Just recovering the initial cost, regular maintenance and regular repair would take half or more of the service life of the vessel , And then there's the lost money from the amount of cargo / container space this system displaces.

This has been actually measured from satellites the whole earth is growing greener as a result of carbon dioxide in the atmosphere. So it's increasing agricultural yields, it's increasing the forests, it's increasing all kinds of growth in the biological world and that's more important and more certain than the effects on climate." ~Freeman Dyson, Institute of Advanced Study in Princeton, New Jersey.

It's a bit off topic. Because the main topic of the video is carbon neutral naval propulsion technology. But, yes. I agree that more carbon dioxide has a positive effect on greening of the planet and increasing agricultural yields. I do not agree that this is a non climate effect. When the world gets greener it means there are more plants and larger plants. This translates into more carbon dioxide that is taken out of the atmostphere. If carbon dioxide is the actual main driver, then this means it should have a positive impact on temperature as well.

"There are huge non climate effects of carbon dioxide.....". You need to read up on our primordial climate and the types of trees and plants that evolved due to the high levels of carbon in the atmosphere at those times. As the levels of carbon sequestered out of the atmosphere, proportionally into these plants, different types of plants (low carbon plants) then evolved. As the carbon levels now increase the types of plants that suit high carbon atmospheres will begin to re evolve. Not in yours or my life time. There cannot be 'non climate effects' if you increase the proportional base of co2 in the atmosphere. It's a closed system. As for your 'the earth is getting greener' comment I don't know what satellite images your looking at but the bulk of the images I have seen from satellites going as far back as the early seventies would indicate otherwise.

You’re repeating a talking point that has been solidly debunked. Factors that plants don’t necessarily become greener with more CO2. It depends upon the species of plant in most cases they also require more water. Most significant is the traditional farming areas are drying out and other areas are becoming flooded so it’s not quite as simplistic.

The thing about sails is they also stabilise the boat during rough sea, so you are less likely to have roll overs if used correctly, if used incorrectly they can actually increase roll-over. But that can be said about a lot of things, modern ships have so many complex control methods to stabilise these huge ships during rough sea that could be completely taken over by large sails.

For the great majority of ships, I think kites will be the way to go. It can all be set up in the very bow of the ship and will not interfere with loading/unloading operations. Kites being controlled to fly in a figure eight pattern can significantly increase the effective wind speed and generate far more lift for a given area. Furthermore, the force it exerts on the ship can be brought aboard down at deck level where it doesn’t contribute any heeling moment. Kites can be flown at higher altitudes where wind speeds tend to be higher and more constant. There’s already a set it and forget it model on the market.

The main issue is bunker oil used in marine Diesel engines with little to no after treatment is sickening for human to breath the fumes. It's impossible for greenhouse gas behavior to cause global warming. Global warming was officially stated at 1.1°C in 1991 and 1.06°C in 2022. There is no mechanism that would allow greenhouse gas behavior to cause global warming. The back of the United Nation's IPCC science report states it took its greenhouse gas samples at 20,000 meters altitude where it is common high school level knowledge there is no greenhouse radiant energy. This is typical practice for deceptive marketing to state legal data transparency protecting the perpetrators from fraud prosecution. The IPCC has been transparent with its data acknowledging it is not dealing with active greenhouse gases. Earth's greenhouse effect is frequently used as a primary example to high school students of a system always in saturation from the strong greenhouse gas water vapor absorbing all the greenhouse radiant energy from the earth with greenhouse gases within 20 meters of the surface that is all around us everyday and can't have its overall effect changed. There is no further greenhouse radiant energy to interact with greenhouse gases. At 1% average tropospheric water vapor over 99% of earth’s greenhouse effect is from water vapor. Water vapor would hold earth's greenhouse effect in saturation if it were the only greenhouse gas in the atmosphere. Arctic warming is taking place with the proving mechanism being warm Atlantic Ocean waters migrating deeper and more frequently into the Arctic Ocean warming it and the region. That warmer water is causing a few weeks less of reflective snow and ice coverage resulting in more solar heat gain to the Arctic region surface. Atmospheric CO2 levels of 1200 ppm about three times what they are today would greatly invigorate C3 plants the majority of plant life on earth greatly greening the planet. 0.4% of the atmosphere is CO2 and on average 1% is H20 water vapor. (1% H20)/(0.4% CO2) = 25. Water vapor is 25 times more present in the atmosphere on average than CO2. Water vapor has an CO2e of 18, 18 X 25 = 450 CO2e total for water vapor to 1 CO2e for CO2. The Earth’s oceans have 3-1/2 million sea floor volcanic vents warming the water and changing it’s chemistry that have not been systematically accounted for.

Chat-GPT, when used as a "Google 2.0" is helpful in situations like this. Here's a quick response/fact-check: "Certainly! Let's delve deeper into each point of the argument to critically analyze its accuracy and provide detailed corrections where necessary. ### 1. **Impact of Bunker Oil and Marine Diesel Engines** **Analysis:** - **Health Impacts:** Bunker oil, used in marine diesel engines, contains high levels of sulfur and other pollutants. Burning this oil releases sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter, which can have detrimental effects on air quality and human health. This is a well-documented issue. However, this concern is distinct from global warming and greenhouse gases, as it primarily pertains to local air pollution and health impacts. **Correction:** - **Focus on Greenhouse Gases:** While the pollution from bunker oil affects air quality, it does not directly relate to the broader issue of greenhouse gas emissions and their role in global warming. To understand global warming, one must consider greenhouse gases like CO2, CH4, and N2O, which differ in their environmental impact from pollutants like sulfur dioxide. ### 2. **Greenhouse Gases and Global Warming** **Analysis:** - **Greenhouse Effect:** The greenhouse effect, caused by gases like CO2 and methane, is a well-established scientific phenomenon. These gases trap heat in the atmosphere, leading to global warming. This is supported by extensive research and climate models. - **Temperature Records:** The claim that global warming was officially stated as 1.1°C in 1991 and 1.06°C in 2022 is misleading. In 1991, global warming was not measured with the same precision as today. The temperature increase relative to pre-industrial levels is more accurately tracked with current data showing an increase of around 1.1°C as of the early 2020s. **Correction:** - **Scientific Consensus:** The assertion that greenhouse gases cannot cause global warming is incorrect. The scientific consensus is that greenhouse gases, including CO2, contribute significantly to global warming. The 1.1°C figure reflects the warming observed since the late 19th century, not a specific annual measurement. ### 3. **IPCC Sampling and Greenhouse Gas Data** **Analysis:** - **Sampling Locations:** The IPCC does not solely rely on data from 20,000 meters altitude. Instead, it uses a range of data sources, including ground-based observations, satellite data, and atmospheric measurements at various altitudes. - **Transparency:** The IPCC is known for its rigorous peer review and transparent reporting. Claims of deceptive practices regarding sampling are not supported by evidence. The IPCC reports include detailed methodologies and data sources. **Correction:** - **Misrepresentation:** The statement about IPCC data collection practices is inaccurate. The IPCC utilizes comprehensive and varied data sources, including lower-altitude measurements where greenhouse gases are prevalent. The claim of deceptive marketing does not reflect the IPCC’s established practices. ### 4. **Greenhouse Effect and Water Vapor** **Analysis:** - **Role of Water Vapor:** Water vapor is the most abundant greenhouse gas and plays a significant role in the greenhouse effect. However, its concentration is not constant and is influenced by temperature changes. CO2 and other greenhouse gases drive the increase in global temperatures, which then increases water vapor. - **Saturation Myth:** The argument that the greenhouse effect is saturated and cannot change is incorrect. While water vapor does contribute to the greenhouse effect, CO2 and other gases still significantly impact global temperatures. Water vapor acts as a feedback mechanism rather than a primary driver. **Correction:** - **Complex Interactions:** The greenhouse effect is not "saturated." Greenhouse gases interact in complex ways, and CO2 is a primary driver of global warming, while water vapor amplifies the effects. The notion that the greenhouse effect cannot change is a misunderstanding of how these gases interact. ### 5. **Arctic Warming** **Analysis:** - **Ocean Warming and Ice Melt:** The argument that warm Atlantic waters contribute to Arctic warming is valid. The influx of warmer ocean waters into the Arctic accelerates ice melt and contributes to regional warming. **Correction:** - **Accurate Contribution:** The warming of Atlantic waters and its effects on Arctic ice is a well-documented process. This factor is part of the broader climate system's response to global warming and should be considered within the context of overall climate change impacts. ### 6. **CO2 and Plant Growth** **Analysis:** - **CO2 and Plant Growth:** Increased atmospheric CO2 can enhance the growth of C3 plants, which can contribute to a "greening" effect. However, this does not account for other factors such as nutrient limitations, changes in water availability, and temperature extremes that can offset the benefits. **Correction:** - **Complex Effects:** While higher CO2 levels can promote plant growth, the overall impact on ecosystems is complex and involves multiple interacting factors. The claim that elevated CO2 will universally result in a greener planet oversimplifies these dynamics. ### 7. **CO2 and Water Vapor Concentrations** **Analysis:** - **Concentration Comparison:** Water vapor is more prevalent than CO2 in the atmosphere, but comparing their concentrations does not directly translate to their relative impacts on global warming. Water vapor’s effect is enhanced by the warming caused by CO2 and other greenhouse gases. - **CO2e Calculation:** The calculation of CO2e for water vapor is oversimplified. Water vapor’s role in the greenhouse effect is part of a feedback mechanism rather than a direct comparison to CO2 levels. **Correction:** - **Effectiveness and Mechanisms:** The comparison of CO2 and water vapor concentrations does not fully address their relative impacts. Water vapor’s role as a feedback mechanism and its interaction with other greenhouse gases must be considered in the context of the broader climate system. ### 8. **Volcanic Vents** **Analysis:** - **Volcanic Influence:** Volcanic vents do contribute to ocean warming and can affect ocean chemistry. However, their impact is relatively minor compared to human-induced greenhouse gas emissions, which are the primary drivers of recent global warming trends. **Correction:** - **Minor Contribution:** While volcanic activity does play a role in ocean processes, it is not a major factor in recent global warming compared to the significant impact of greenhouse gases. The role of volcanic vents should be considered within the context of their relatively small contribution to overall climate change. ### **Summary** The argument presented contains several inaccuracies and misunderstandings about climate science. The greenhouse effect, the role of greenhouse gases like CO2 and methane, and the complex interactions involving water vapor are well-supported by scientific evidence. Misrepresentations of IPCC practices and oversimplifications regarding greenhouse gas impacts contribute to a flawed understanding of climate change. Accurate climate science emphasizes the complex and multifaceted nature of global warming, driven primarily by human-induced greenhouse gas emissions."

Roll out the better and cheaper practical solutions and do not worry about the rest - people will go for them, as they did in the past and lifted ours civilization to the amazing levels we are at now. This alone, and not the ideological labels of 'greeneness', 'sustainability', 'ecofriendliness', 'renewability' and alike phantasies shall move the things forward.

Yep. Just purchased a '25 hybrid Camry that gets 45 - 50 mpg with over 500 miles range. Replaced an Audi Coupe. Rode my BMW thumper mc and thought I could have regenerative braking also and a lot more torque. I sail a 32' trimaran with rotating carbon fiber mast and boom. Also, sail an 11 foot inflatable Hobie pedal board.

Thats incredible, just imagine if the sails served as solar cells as well! Maybe in the future there will be someway this could be made possible. Just an idea Ive had. It would be extremely interesting to have a ship thats exterior surface was solar panels of some sort. For both increasing speed and creating energy aboard. Even the sides of the ship could be utilized for harnessing solar energy. As the reflective surface of the water below would likely increase tge amount solar energy collected. I think its very possible to create such a sailing/ solar ship. Id build it myself if I had the funding.

Just as with the land based production of power (electricity) people are refusing to consider the one source that would solve all the issues: NUCLEAR ENERGY. Safer and more environmentally friendly than either fossil fuels or rare earth based batteries. The reactor designs are already available and have been for years.

When I was a kid, I had a magazine called ‘Insight’, there were a number of articles in that regarding the super futuristic large sailing ships that were coming, this was in the early 80’s, Turn of the century they said we would be using sail to move super massive carriers of Ore and Grain. Hasn’t happened yet.
