鳖的科技爆炸呀，海水直接电解制氢

Re: 鳖的科技爆炸呀，海水直接电解制氢
你们这些法轮功和民运都是低级黑高级红，为反而反，从来不知道实事求是。NMB不干正事，整天喊什么“中共邪教、天灭中共”这种智障傻逼话，只会让正常人更反感反共这群人，这就是为什么现在都把这群傻逼称为轮子和民逗，真是成事不足败事有余，我都怀疑是不是已经被共产党收买了故意这么搞的。还有民逗整天制造低水平智障谣言，企图用一个谎言去击败另一个谎言，但是当谎言被戳穿就再也没有人相信你了。前几年墙内大面积转向粉红的重要原因之一就是各种民逗和sb公知炮制的谎言被戳穿了。

不如直接烧海水。

Re: 鳖的科技爆炸呀，海水直接电解制氢
2 里制甲烷用的二氧化碳就是1里产生的二氧化碳？1 托克托电厂一年烧煤两千万吨，产生二氧化碳六千多万吨
2 用蒙藏疆的太阳能，电解水制氢后加二氧化碳制甲烷，通过管道送到沿海火电厂。
3 里沿海天然气火电厂的天然气，指的就是 2 里制的甲烷？3 沿海核电厂通过制氢，变成调节电厂，白天把沿海天然气火电厂排放的二氧化碳加海水制氢，变成四千多万吨甲醇。
4 四千多万吨甲醇作为货运燃料，取代两千多万吨汽油。

薄膜的寿命已经验证到了3200小时，实用化大有可能。jiujianoufu 写了： 2022年 12月 1日 14:06 只发表一篇文章算他妈的屁。在我看来，这项技术面临的应用问题太多，如电极的寿命，薄膜的寿命，运营的费用等等。任何一个应用的因素考虑不到，这项技术的价值等于零。

Re: 鳖的科技爆炸呀，海水直接电解制氢
他鳖独立发明。就像他鳖刚刚经研究发现奥姆克戎致病力就是普通感冒（不是流感）水平。
那个lahei、foofy以及戴着遮羞布的婊子不用费事回我的帖了。我分别用了一个伪币把它们放在屏蔽傻x列表里，我既看不到，更回不了。
因为军版傻x列表屏蔽功能不完善，特此在个人签名处补充，lahei、foofy以及戴着遮羞布的婊子，若回我帖子死全家。

不提供能量怎么可能过滤海水？这个是违反第二定律的
sdehc 写了： 2022年 12月 1日 13:00 这工作就是在不提供额外能量的情况下，用膜过滤海水，让杂质不参与电解呀。

Re: 鳖的科技爆炸呀，海水直接电解制氢
sdehc 写了： 2022年 12月 1日 12:54 海水不淡化直接制氢当然是新发明。要不能上nature？何况这个已经试验了三千多小时，膜效率不下降。
鳖可以不大建内陆核电了。沿海核电厂以后就是发电厂加甲醇工厂，鳖的交通运输完全抛弃石油，客运用电，货运用甲醇，鳖的能源问题彻底解决。

这个说法违背热力学第二定律，和永动机一样，是不可能实现的。sdehc 写了： 2022年 12月 1日 13:00 这工作就是在不提供额外能量的情况下，用膜过滤海水，让杂质不参与电解呀。

任何分离都需要能量投入，说不投入的全是骗子。
Re: 鳖的科技爆炸呀，海水直接电解制氢
文章而已？sdehc 写了： 2022年 12月 1日 12:46 以后核电站是否可以参与调峰？白天沿海地区用内陆新能源，沿海核电站负责制氢。晚上核电站再负责供电。
白天制的氢跟火电厂排放的二氧化碳反应，变成甲醇，以后的truck必须烧甲醇，我鳖就能源自给了。
A membrane-based seawater electrolyser for hydrogen generation
Re: 鳖的科技爆炸呀，海水直接电解制氢
arstechnica的科普：
https://arstechnica.com/science/2022/11 ... -seawater/
Waterproof, breathable clothing relies on a membrane with carefully structured pores. The membrane is made of a material that repels water. It has pores, but they are too small to allow liquid water through. But they're big enough that individual water molecules can pass through. As a result, any water on the outside of the clothing stays there, but any perspiration on the inside that evaporates off will still flow through the fabric and make its way to the outside world. As a result, the fabric breathes.
A similar membrane is central to the function of the new device. It keeps liquid water from transiting across the membrane but allows water vapor to pass through. The big difference is that there's liquid water on both sides of the membrane.
On the outside, there's seawater, with its standard collection of salts. On the inside, there's a concentrated solution of a single salt—potassium hydroxide (KOH) in this case—that's compatible with the hydrogen-producing electrolysis process. Submerged in the KOH solution is a set of electrodes that produce hydrogen and oxygen on either side of a separator, keeping the gas streams pure.
So what happens once the hardware starts operating? As the water inside the device is split, producing hydrogen and oxygen, the reduced water levels increase the concentration of the KOH solution (which had started out much more concentrated than seawater). This makes it energetically favorable for water to move across the membrane from the seawater to dilute the KOH. And, because of the pores, that's possible, but only if the water moves in vapor form.
As a result, the water briefly exists in the vapor stage while inside the membrane and then quickly returns to liquid once it's inside the device. All the complex mixture of salts in the seawater is left behind outside the membrane, and a constant supply of fresh water is provided to the electrodes that split it. Critically, all of this takes place without the energy use normally involved in desalination, making the overall process more energy-efficient than cleaning up water for use in a standard electrolyzer.
