I think in 2050, most cars will be Fuel Cell Energy Vehicles (FCEVs).
Recently ‘internal combustion engine cars’ use hydrogen as a fuel. Hydrogen engine efficiency is not high than hydrogen fuel cell because of the ‘Carnot cycle’ theory.
Of course, hydrogen engine effciency is high than gasoline engine or diesel engine. Carnot cycle is most high thermal efficiency among the moving cycle. In contrast, the hydrogen fuel cell efficiency is very high because it is electrochemical devices.
Therefore, in the future most cars will use hydrogen fuel cell.

Hello richard, I’m seung uk
Last class, I watched very interesting lecture which is called TED. TED provides many information in various fields. Among many fields, I watched Fuel Cell Energy Vehicles (FCEVs). This subjects is one of the future concerns. During I watched the Ted, I think that most cars will be fuel cell energy vehicles in the 2050.
Because, these days most people know that internal combustion energy cars have a bad effect on environments. So many researcher strive to solve this problem and already finished making fuel cell energy cars which replace past internal combustion energy cars. So I think that in 2050 fuel cell energy cars will be commercialized.

I think Fuel Cell Energy Vehicles (FCEVs) more than internal combustion engine cars in 2050.
Fuel Cell Energy Vehicles (FCEVs) make almost never exhaust gas, but internal combustion engine cars make a lot of exhaust gas. Therefore, Fuel Cell Energy Vehicles (FCEVs) contribute to environmental preservation, however it is difficult that these become popular. Because these cost a lot of money.
But I think these will become popular in 2050. Because people will research hydrogen fuel cell engine for 35 year, so this will make more cheap and better engine. In addition today, hydrogen stations exist 13 in Korea, but I think those will increase in 2050.

Hi richard
The car and bus are currently the main mode of transport for the vast majority of mankind. However, throughout the world petroleum resources are gradually exhausting, provoking huge problems as the greater part of people utilize such transport. In addition, the problem of ecological safety is another issue: the share of the toxic substances which are thrown out by petroleum transports exceeded 60% of all emissions for industries. As technology advances, fuel cell energy vehicles like the Honda FCX Clarity which was introduced in 2008 are a part of our future. Moreover, as scientists continue to develop fuel cell energy it will overcome both problems of ecological pollution and exhausting the petroleum resources. Hence, I think the majority of cars will convert to fuel cell energy vehicles by the year 2050..

Hello~ Richard!!
I think Fuel Cell Energy Vehicles (FCEVs) more than internal combustion engine cars in 2050.
Because Fuel Cell Energy Vehicles(FCEVs) are very Eco-friendly energy, so never make air-pollution. but internal combustion engine cars can't it.
These days, actually making Fuel Cell Energy Vehicles (FCEVs) cars. for example, hydrogen cars. this car is cheap fuel and eco-friendly engine. so I think Fuel Cell Energy Vehicles (FCEVs) cars will increase in 2050.

In my opinion, I think we will almost have hydrogen fuel cell cars by 2050.
We can reduce environmental pollution by using the cars, and can also get the materials easily. These are advantages of those cars.
But the easy way of charging system like a gas station is not built yet. Getting hydrogen is not systematic, and the car’s structure is different from existing car’s. It means that it would be expensive to produce. These are limits of the cars.
I hope these problems will be solved by 2050. Therefore most cars will be Fuel Cell Energy Vehicles until then.

Hi, richard
I think people will use Fuel cell energy vehicles, because, these day people almost waste petroleum, and now finding new enegy. so, as a result, these day, some of people use Fuel Cell Energy Vehicles and more and more people will use Fuel Cell Energy Vehicles, Therefore people will use Fuel Cell Energy Vehicles in the 2050.

Hello, Richard!! I`m Gwanwoo
Fuel Cell Energy Vehicles constitute the majority of cars. Because, Our enviroment situation is very serious. So our enviroment reserchers look forward to clean enviroment. We have to try clean the air, water and etc. In this situation, All of the people want Fuel cell energy vehicles.Internal combustion engine cars pollute the air certainly. So , Most cars will be Fuel cell cars at 2050 years.

I think most people will use Fuel Cell Energy Vehicles by 2050. Because petroleum is limited resources. Someday all petroleum is exhausted. Then people want new solution of resources, Fuel Cell Energy Vehicles will be used consequently. As example, hydrogen car and electronic car are invented. But now these cars aren't usually used because of short mileage. However by 2050, these cars will be used clearly. Thus I think most people will use Fuel Cell Energy Vehicles by 2050.

I think we will have internal combustion engine cars.
Because, Currently living in the community, we use fossil fuels.
But this fuels are being depleted. These day cars have internal combustion engine. Then, cars of that way will be discared. But, Fuel Cell Energy Vehicles not need discard. Because, Fuel Cell Energy Vehicles are not need fossil fuels. And FCEV use clean energy so pollution is not caused. Although now FCEV technique are lacks, in 2050 years FCEV technique will improve. Fuel Cell Energy Vehicles (FCEVs) or internal combustion engine cars have Advantages and disadvantages, anyway i wish pollution, fuels and so on will be sloved.

I think internal combustion engine cars more than Fuel Cell Energy Vehicles (FCEVs) in 2050.
Fuel Cell Energy Vehicles (FCEVs) make almost never exhaust gas, but internal combustion engine cars make a lot of exhaust gas. Yes. That's true. But 2050 is too short for change. Because we have a car good efficient enough. And, Fuel Cell Energy Vehicles (FCEVs) have good efficiency, but still expensive and danger than internal combustion engine. In addition today, we usually know that FCEVs is slower than internal combustion engine cars.

I think Internal engine will be the most cars’ engine by the year 2050. The reason is not that internal engine is more efficient. The reason is that FCEVs engine will not commercial by the year 2050. If FCEVs engine is commercialized, It will spread quickly. However, To commercialize, A lot of technologies have to be developed. It’s not easy to develop. the engine made from the developed technologies should be safe, light, and efficient. I think it will difficult by the year 2050.

2050, the car is a lot of energy will be used in a FCEVs . It is like the current one day run out of oil and polluting the environment. Solar energy and FCEVs, but other media to create energy, so no pollution and depletion of fuel because the FCEVs by 2050, there will be a universal being.

Hi Richard.
In this choice between fuel cell energy vehicles and internal combustion, I would select fuel cell energy vehicles. When I watched two vehicles by media in lecture, I had to select fuel cell energy vehicles. Because many of these days, there are so many cars and gas in city even in country, so we have to minimize gas using cars. There would be many kinds of method to minimize gas. In these methods I think we must use fuel cell cars to minimize gas. And there are many things showing that fuel cell cars are more efficient than internal combustion cars. So I think fuel cell cars will be most cars in 2050.

Hello! Richard. I think Fuel Cell Energy Vehicles (FCEVs) will be more than internal combustion engine cars in 2050. In the future, we will live in Eco-friendly state from all sides. FCEVs are environmentally very stable cars. Because FCEV is a type of vehicle which uses a fuel cell to power its on-board electric motor. Fuel cells in vehicles create electricity to power an electric motor, generally using oxygen from the air and hydrogen. So FCEVs will become the next generation of cars. Currently the price of hydrogen cars and the 150 million won. More expensive than electric cars. However, in the coming era, the hydrogen car 120% of the price of conventional gasoline-powered vehicles is expected to fall around.
Therefore, people will use Fuel Cell Energy Vehicles in the 2050.

I think internal combustion engine will remain in 2050. Hydrogen fuel cell cars market significantly increase. Because it not emit waste gas and not need fosil fuels, it have been prefered by customers who consider maintenance expenditure or think about environmental pollution. But it has some problems. First, Battery has short durability. So, fuel cell car owners have to replace it once every four or five years. Second, It's too silent to enjoy a driving. Lastly, it's more expensive than Internal combustion engine car. Most of them will be solved until 2050. But Internal combustion engine still has been improved and it will remain like a hybrid engine. That's why i think that.

In my opinion, we will have only hydrogen fuel cell cars by 2050.
Because these days, pollution due to exhaust gas, fossil fuel is very serious. Because of pollution, natural disasters are happening and the earth warmer phenomenon is accelerating now days. Beacause of these reasons, people will use hydrogen fuel cell cars which make no pollution. And hydrogen fuel cell cars will be used for power grid. But hydrogen fuel cell cars are expensive and not popularized for people. Engineers are responsible to make hydrogen fuel cell cars popularize to people and then we will use hydrogen fuel cell cars by 2050.
In my opinion, Fuel Cell Energy Vehicles more than internal combustion engine cars in 2050. Because we have environment pollution and we must plan measure to exhaust gas. If we use Fuel Cell Energy, we don't have any pollution. But Hydrogen Fuel Cell Energy is impact on our environment.
So I think we will use Fuel Cell Energy in2050, must use it.

Hi, Richard. I think Fuel Cell Energy Vehicles (FCEVs) will be more than internal combustion engine cars in 2050. Because people always worried about environmental pollution. So, Scientist and Engineer will find new methods. Fuel Cell Energy Vehicles (FCEVs) is good method to protect earth. So, In 2050, most cars will be Fuel Cell Energy Vehicles (FCEVs)
김석원 2014120019 2분반
i think Fuel Cell Energy Vehicles is good idea
beacuse our techknowlogy is better then now
Fuel Cell Energy Vehicles will be positive for enviroment and earth
so i agree this idea it will be realize soon
hello richard i'm 조우성 2013140130 35class
i think Fuel Cell Energy Vechicles will be more than internal combustion engine cars in 2050. because i think FCEV is too simple and easy for devalop. we must focusing on the usability not effectiveness. and also we must need to think at next generation. So i think most cars in 2050 is use FCEV
2014120119 최정훈 class 8
Hi richard.
I think Fuel Cell Energy Vechicles will be more than Internal Combustion engine cars in 2050. In that time
I think Combustion engine cars will be no more exist. And Now Fuel Cell engine cars are so expensive that
we buy it. But after 40years later It has possible that we can buy Fuel Cell engine car in cheap price.
And As you know Combustion Engine cars are very not good at Air environment. That is why we are developing
Fuel Cell Engine car. So there are still a lot time in 2050, at that time We believe that We can buy that
car.
Class8 2014120114 조준열
I think internal combustion engine wiil remain and still be used in 2050. If we use Fuel Cell Energy Vehicles (FCEVs), we need a lot of changes.
We replace car's engine with fuel cell energy engine. It cost very much. And now, we fuel car at gas station. If we use Fuel Cell Energy Vehicles (FCEVs), we have to substitue fuel cell station for gas station.
Fuel Cell Energy Vehicles (FCEVs) need many technology. It have still maked now, but it's not commercialized. Becasue, we have used internal combustion car until now, it's hard to change our style.
조유진 2014120113 class 08
I think Fuel Cell Energy Vehicles (FCEVs) will be more than internal combustion engine cars in 2050. the reason is that utilizing the chemical reaction of hydrogen and oxygen, a fuel cell powered electric motor in such a way that the futuristic vehicle. then, since there is no exhaust gas air pollution can be prevented. and reducing operational costs through the fuel efficiency can be performed. for this reason, Fuel Cell Energy Vechicles will usually use in the future.
2013140120전민재 35분반
Hi, Richard. I'm 전민재
i think Fuel cell Energy Vechicles will be use our in 2050.
because Fuel cell Energy Vechicles have many advantage
that Hydrogen fuel cell car can't reach.
but technical skills are enough to make Hydrogen fuel cell powerfull.
so i think FCEV are use in 2050.
Also i think in 2050, We can't imagine what will be invented.
2014120115 주수호 08 Thu
In my opinion, Fuel Cell Energy Vehicles will be more than internal combustion engine cars in 2050. Because nowadays environment pollution is sensitive thing in the world. By 2050, maybe i think new technology to protect earth environment will be developed.
So,by 2050, most cars will be Fuel Cell Energy Vehicles.
2012140101 이연지 08분반
I think Fuel Cell Energy Vehicles will be most car by the year 2050. Nowadays, people are developing car engine to change fossil fuel with other sources. Because fuel of internal combistion engine car is running up more and more. Also the internal combostion engine car makes the pollution of our natural environment. We have to protect our earth by developing new engine car to substitute internal combistion engine car by FCEVs. So the car used most now will be changed with new engine car in future and the new car is Fuel Cell Energy Vehicles.
2014120021 김성훈
I think Fuel Cell Energy Vehicles(FCEVs) will be the best cars of 2050. Because FCEVs are cleaner than internal combustion engine cars by hydrogen and oxygen. And hydrogen and oxygen are limitless. And FCEVs are cheaper than internal combustion engine cars by hydrogen and oxygen. And FCEVs have fuel efficiency more than internal combustion engine cars by hydrogen and oxygen.
