You're not going to get people interested in saving the planet by keeping them locked away from it. Why should anyone care about the animals if they don't ever see them? I don't think Avs was suggesting people go poke the Wolves. Merely pointing out that nothing is going to change if humanity remains committed to the idea that it is not part of nature and merely a watcher. Or in your case not even that as looking at the wolves makes them die or something?

Something left out was that a metal membrane is used to extract hydrogen from liquid ammonia, which actually puts it close to on par with liquid fuels. I'm not necessarily optimistic, but on this is an important breakthrough.

Take all the subsidies away from the beef and fossil fuel industries, slap a big ole tax on gas powered vehicles, and use the revenue to heavily subsidize electric vehicles. Hammer it into people's heads that they can use the money they're no longer giving to BP to instead rent high fuel efficiency vehicles for long distance travel, or better yet take a train.

I was joking but in my country (Holland) this isn't such a strange idea, old people in the countryside get around nowadays on electric bikes and since you're never really far from a city and work you can live in the countryside without a car perfectly fine. Whenever I visit most other countries, especially the countryside, I get annoyed at the lack of proper bike infrastructure. It's possible to make the countryside and inner cities more accessible in a carbon neutral way so you can still have big action radiuses without cars.

The hydrogen from ammonia is something else entirely. Oxygen from plants comes from splitting water during photosynthesis, and burning hydrogen would create water (and perhaps some nitrogen oxides), so it's much more balanced. Granted, I too think it is far too late. Evil_Greven fucked around with this message at 15:58 on Aug 19, 2018 |

Gully Foyle posted:Here's a thing though: ammonia is largely made from fossil fuels. Ammonia is just NH3. It's been produced from loving vegetable oil and organic waste (even wastewater), though it's cheaper and easier to produce through fossil fuel refining (primarily natural gas) with some associated energy costs. Those energy costs could be handled by renewables; one of the problems with renewables is getting the power from where it is generated to where it is used, and liquid fuels are a solution. The problem with hydrogen has always been storage, and having a membrane that can convert ammonia to hydrogen on-the-fly is tremendous.

The energy density of fossil fuel and ease of transportation is the really attractive aspect of it when compared with batteries. If it were possible somehow to create liquid hydrocarbon fuel in an efficient and carbon-neutral way, it would be far, far better than batteries.

Is the proposal that we create enough vegetable oil that we then use renewable electricity to create ammonia to store hydrogen to run cars? How many times less efficient is that than just using renewable electricity to power batteries to run cars? How much electricity is lost from generation to the point that it is transmitted to a battery?

twodot posted:Yes, if you can create an object that is more energy dense than a battery and as carbon-neutral as a battery, you will have made a better thing than a battery. That's pretty close to what this is. Non-renewable power plants themselves lose something like 2/3 of energy from fuels in order to generate electricity, of which at least another 1/16 or so is lost in transmission (high voltage lines are actually very efficient; it's the step down to low voltage lines where it gets leaky). An undetermined amount of energy is lost on leaky household power to the battery. Batteries don't store AC, so it must be converted to DC, which is typically another 1/5. This loss is mostly offset by the efficiency of electric motors, which might lose between 1/10 and 2/5, compared to internal combustion engines that lose between 3/4 and 4/5. So, at the end they are rather similar in efficiency. However, batteries themselves are an issue. They're heavy, they don't get lighter as energy stored decreases, they are limited in energy storage, they are limited in storage cycles, and are currently not practical for aircraft. Renewables plants losing energy is essentially irrelevant, but it currently makes up under 1/5 of U.S. electric grid production. A further 1/5 is from nuclear plants, which leaves over 3/5 from fossil fuels. On the other hand, hydrogen stored in ammonia could be either burned in an internal combustion engine or used in a fuel cell. Fuel cells are technology we already have to generate electricity directly from hydrogen and oxygen, with typical loses between 2/5 and 3/5, and can then immediately power highly efficient electric motors. Natural gas could still be used to produce ammonia, rather than burned for fuel as it currently is. Evil_Greven fucked around with this message at 18:04 on Aug 19, 2018 |

It's like someone worrying where you could get carbon for some process and someone saying "carbon is everywhere, you could get carbon from a shoe" then someone taking that to figure out the efficacy of some sort of shoe supply chain to get carbon.

Meanwhile you have still left the topic of "What metrics does Owlofcreamcheese think are good for evaluating policy given Owlofcreamcheese has rejected cost efficiency as a metric?" unresolved. OOCC interpreted it correctly. There are many sources of ammonia, such as those examples. The hard part is getting hydrogen, though it can be done rather efficiently from natural gas. Hydrogen is indeed mostly from fossil fuels, but this is different than burning fossil fuels. The carbon emissions from steam reforming are easily captured, and are sold for other applications.

For example, your posts in this thread lead me to believe that having to fly less is enough to induce fear-based paralysis in you. That's, uh, pretty unreasonable, so I have no idea how to communicate with you at all. Mann is arguing against narratives that say in no uncertain terms that climate change will be the end of civilization, not against suggestions that things may have to change for some people in rich countries. I've actually posted a ton in this thread about the need for collective action over individual action, but part of that is selling to people the idea that collective (ie, political) action may lead to some changes in how they live their lives.
