How Solid State Microwave Emitters Improve Converting Waste into Energy and Cook Bacon Better

- We can now generate microwaves with solid state devices instead of magnetrons. This is a big deal because solid state microwave generators make extracting hydrogen from waste way more efficient.
And they make a new generation of microwave ovens possible. Ovens can cook an entire meal at once, perfectly.
With solid state microwave generators, we can make a home appliance the size of a dishwasher that turns the trash into electricity to power your home.
Here’s are rough calculations for how much energy could be produced such an appliance.
E_in = 1,000j/s X 90 seconds = 90,000j
hydrogen in plastic = 11%
hydrogen in 300g plastic = 0.11 X 300 = 33g
extracted hydrogen = 0.97 X 33g = 32.01g
hydrogen energy density = 131,000 joules/gram
heat energy = 32.01g X 131,000j/g = 4,193,310j
heat engine efficiency = 40%
mechanical energy = 0.40 X 4,193,310j = 1,677,324j
electric generator efficiency = 92%
electrical energy = 0.92 X 1,677,324j = 1,543,138.08j
E_out = 1,543,138j
E_out/E_in = 1,543,138j / 90,000j = 17.15

There is an error at 2:45 regarding the description of plasma. It says "The electrons and its atoms detach from the nucleii", which is nonsense.
That is nonsense. I'm not sure how I let that through. I apologize for that misinformation. I think if we take out "and its atoms" it would make sense.
The references to the literature are years old. Doesn't look like the tech has really taken off much to become a mainstream player.
Thanks for watching the video. Some of the references are more recent than others. For example, the reference to Royal Caribbean's Icon of the Seas. I'm not sure what standards an organization needs to meet to be considered a mainstream player, but that is not the purpose of this video. It is intended to encourage viewers to consider the benefits of using microwave assisted plasma to reduce waste and generate energy. I appreciate you viewing and comment.
Well you got my attention. Thanks. I have been following developments in new tech solutions to world problems. So many seemingly promising innovations end up like fusion energy...always jest a few years years away. Sad fact: we're running out of years to develop solutions on a real global scale. Global warming and the throw away mentality have caught up with us much faster than any one thought. All of this should have been dealt with, by the powers that be, twenty years ago. I'm afraid that the time line for scaling up these technologies to the level needed to make a real impact, is way too slow. Governments aren't responsive, the world population is generally apathetic. Unless we have a general sea change in attitude by everyone, I'm afraid we are truly screwed.
So graphene just falls out? That alone makes me call bullshit on the whole thing. Why the hell should carbon assemble to sheets literally in mid air, in the plasma cloud? It would be easier to believe if they would say< that diamonds fall out.
Okay, saying "drop out" is a bit loose. But it does form under the right conditions. Check out the research done at Rice University. Thanks for watching, paying attention, and commenting.
"Break down" - yeah, everyone has had those pesky ever-lasting magnetrons break down.
"More efficient" - I'd like to see that explained, how a self-oscillating inductive-capacitive cirquit fed by a HV transformer lags behind in that are.
"Some or other obscure brand heats up food perfecly" - yes you see modulating microwaves by a semiconductor completely does away with standing waves inside a microwave oven because they magically spread out and become homogenously even.
My personal favorite is doing pyrolysis with microwaves. That's right, because all hydrocarbons love microwaves, even those that ignore the s××× out of them because they're transparent to them.
Not to mention that generating microwave by semiconductors are, at least for now much inefficient than magnetrons (or reflex klystrons) and to make them wideband is a nightmare because of the matching problems for FET transistors.
I am unable to argue with you about this. Perhaps you need to contact the engineers at ITW or NPX. I can say that when I was studying electrical engineering in the 1970s, two very experienced engineers cautioned me not to learn about semiconductors because they were just a fad.
There's quite a few research papers that address some of these issues. "Conversion of waste polystyrene into valuable aromatic hydrocarbons via microwave-assisted pyrolysis" is one.
@@markinoWindsurf perhaps you need to provide actual arguments instead of throwing things out there, because of literally all microwavr ovens sold none are solid state, and like I said I have NEVER head of a magnetron failing.
And oh no... a paper about something! Of POLYSTYRENE of all things! What a critical resource, and what a useful process it would be of microwaving it instead of running conventional pyrolysis! Gees.
Who the hell has a microwave repaired?
Home microwave ovens rarely need repair. But my friend did have the magnetron in his oven die. It had to be replaced. However, food preparation services run their ovens continuously many hours per day. Worst case, they replace a magnetron every six months or buy more expensive ones that last longer. Thanks for your comment and for watching the whole thing.
@@markinoWindsurf I'd think it would be cheaper just to buy a new microwave these days...Although it takes about 10 minutes to replace a magnetron. The real question is...Can you make a microwave laser with the solid state parts??
Yes but it takes a lot of energy to make microwaves and hence expensive- thermodynamics laws are still valid.
Thank you for watching the video. I hope you saw the calculations near the end of the video that address this issue. They are also in the description. The calculations are based on reproducible experiments done at Rice University, the University of Oxford, and other research facilities. The calculations show that the amount of energy needed to generate the microwaves that produce plasma is less than the amount of energy that is generated by the device.
