The Future of Clean Energy: Crash Course Engineering #31
video description
- uses hydrogen fuel cells and biogas turbines to run the plant.
- hydrogen is collected from seawater using electrolysis.
- Wastewater is collected. The incoming flow of wastewater is also energy for the plant to collect.
-solid/insoluble waste is filtered out and burned in a biomass boiler. This can be used to heat the digesters, the central heating of offices and/or preheat water to improve efficiency of biogas turbine power. The ash produced can be collected for building/composting.
- The wastewater is then condensed and digested to produce biogas. The biogas can power the plant and/or be distributed for other services.
-the inert sludge from biogas production can be distributed for agriculture.
- The separated water from the refuse is then treated with the biproduct of the electrolysis (sodium hypochlorite) until it is safe enough to be redistributed to the public (grey water supply) for flushing toilets and agriculture. Excess chemical can be distributed for other services.
-The hydrogen produced by the electrolysis can also power the plant by HFC use or distributed. The biproduct being distilled water. This can be distributed to the public also with the treated wastewater, where it can remineralise through the ground and return to water courses, or top up the water supply used to distribute heat around the premesis and run the turbines.
A plant like this would then be beneficial in which:
-the abundance of seawater is converted indirectly into useable fresh water. Improving available water resources.
-Wastewater is treated and redistributed in a cost neutral fashion, also improving available water resources.
-Soil quality is vastly improved.
-Useable gas and electricity is created in vast abundance. Enough to run the plant and sell for profit.
-almost no resources need to be brought in to maintain the process.

Great video! However, you probably should have mentioned breeder fission reactors, which take the nearly limitless supply of fertile isotopes (mentioned in other comments) and converts them to fuel. A good number of reactors have been run that actually produce more fuel than they consume. Also, -don't be fooled- in a weird way of saying that it's the most energy-dense option on your list, so your mining requirements are MUCH lower than for other things. -Nuclear waste- is actually very little considering how much power they produce, and it can be reprocessed or used directly as fuel in fission reactors that don't slow down the neutrons, called fast reactors or burner reactors. Also, I will be very surprised if fusion is ever run in net positive energy, while fission already outputs WAY more energy than input, and currently is the best clean source for now.

I know this is crash course and youre short on time, since youre trying to keep the videos at about 10 mins, but I was a bit dissapointed with the absence of certain topics. Could you maybe do a video about 4th gen nuclear reactors, or carbon capture as a way of making biofuels more environmentally-friendly? I'd personally be mostly interested in a video on the former, since it seems like a more complex topic, and it would be great to have a video that explains the pros and cons of the more viable/promising 4th gen nuclear reactor types. Especially since, from the little research I've done, it seems we're closer to implementing them into the grid than fusion reactors.

A small nitpick, but oxygen producing organisms did actually do a lot of -harm to the planet- when they were new (though not plants, and more than 450 mya. The Oxygen catastrophe was one of the biggest mass extinctions in the planet's history. Oxygen was poisonous to most organisms at the time you see, but eventually organisms evolved to use the oxygen, and a new balance was reached.

A few points of correction about nuclear power (from a nuclear engineer. Nuclear energy makes up 20% of the electricity production in the US not 10%. Also the fission that you-re talking about is with slow moving (thermal) neutrons not fast moving neutrons. That being said, much of the information here is pretty accurate.

the only reason i was able to understand and literally get an A on my test was because she was attractive to me AF and had an accent good thing I'm american. And probably shouldn't text this during valentines day because I might get a steak knife from the back from my bae, but thank you for this info.

OK team. 6: 46 fast moving neutrons don't have any significant effect on the fission process. They have to be moderated by something to turn them into Thermal neutrons, ie slowed down, so that they can interact with fissionable material. More to come, maybe. T. W

I am a lawyer, and soon a doctor, I hope in the future to become a theoretical physicist, and I have never considered myself an engineer, education is closed to each branch and that's why they make mistakes. Because they think the engineers are the only qualified.

Out of date on your nuclear information. Newer generation reactors could burn the waste from old reactors and power the U. S. for hundreds of years, without even mining any new material.
I think they even mentioned this in the PBS documentary on nuclear power.

Nuclear waste is extremely dangerous for an indefinitely long period of time. There have even been talks of creating a nuclear priesthood to pass down the knowledge of just how dangerous it is to generations tens of thousands of years into the future.
