Are glass batteries a hoax?

[Bender]

That makes no difference. They can cancel each other out when parallel as well. Angular momentum doesn't have a position, only an orientation.

Yep, I looked and it's correct. Which seems to negate the objection to flywheels being used to supply power to vehicles.

It makes it more complicated, but it shouldn't wear out your tyres or make you go straight when you turn the wheel.

Nice illustration of it on youtube :

Edit. I guess that maybe the forces on the bearings might be prohibitive. Although wheel bearings seem to take plenty of force in their lifetimes.

Yes, the point I was trying to make is that you have to engineer the system to deal with it (rigidly support the two counter-rotating wheels), and said engineering adds extra weight, cost, and so on. You're right - it shouldn't wear out your tires; the gyro effects would be "contained" by the supporting structure.

 

Another thing you have to keep in mind is what's going to happen if a flywheel fails; those tend to be rather violent events. So you'd also need a containment system, and that adds weight and cost as well. But of course all of these technologies have risks (gasoline can explode too).

That's interesting, but in 2002 someone already attempted to patent a "glass battery", but it was more likely

a hoax. Though description of their "glass battery" more resembled a capacitor.

Stable levitation of one magnet by another with no energy input is usually prohibited by Earnshaw’s Theorem. However, the introduction of diamagnetic material at special locations can stabilize such levitation. A magnet can even be stably suspended between (diamagnetic) fingertips. A very simple, surprisingly stable room temperature magnet levitation device is described that works without superconductors and requires absolutely no energy input.

Are such materials as concrete, asphalt, sand, stone diamagnetics or paramagnetics?

It depends on the minerals inside the concrete, asphalt, sand and stone. Some, such as magnetite, is even ferromagnetic.

Probably, I've posted a post in the wrong thread. It belongs to "plasma cushion levitating cars".

Hi...as per my knowledge the problem is that conductivity of solid electrolytes is much lower than conductivity of liquid electrolytes. This is very difficult to change because it is based on physic's laws. Li-ion batteries commonly use organic electrolytes. They may not be too cheap and are flammable, but at least they offer acceptable power densities. With glass electrolytes power may fell below acceptable level.

It seems like the whole idea is based around the claim that regular Lithium on anode converts to some mysterious low Fermi energy form on the cathode.

Quote

During discharge, a cell plates the metal of an anode of high-energy Fermi level such as lithium or sodium onto a cathode current collector with a low-energy Fermi level; the voltage of the cell may be determined by a cathode redox center having an energy between the Fermi levels of the anode and that of the cathode current collector.

http://pubs.rsc.org/en/Content/ArticleLanding/2016/EE/C6EE02888H#!divAbstract

But it is not clear if Lithium is transferred at all and what is this low Fermi energy form of Lithium. How Fermi energy of Lithium can change?

[Moreno]

It seems detailed patents of Goodenough on glass battery has been published. However he provides little explanations what is "low and high Fermi energies" of alkali metals are. Any suggestions?

METAL PLATING-BASED ELECTRICAL ENERGY STORAGE CELL

Oct 27, 2017

The present disclosure provides an electrochemical storage cell including a battery. The battery includes an alkali metal anode having an anode Fermi energy, an electronically insulating, amorphous, dried solid electrolyte able to conduct alkali metal, having the general formula A3-xHxOX, in which 0≦x≦1, A is the alkali metal, and X is at least one halide, and a cathode including a cathode current collector having a cathode Fermi energy lower than the anode Fermi energy. During operation of the electrochemical storage cell, the alkali metal plates dendrite-free from the solid electrolyte onto the alkali metal anode. Also during operation of the electrochemical storage cell, the alkali metal further plates on the cathode current collector.

It seems now more details are reviled on how Lithium may switch between different Fermi levels. The whole thing looks to work like an EDSL supercapacitor and exploits some quantum effects:

Quote

Schematic of EDLCs at the electrode and electrolyte interfaces during discharge where electric dipoles coexist with the mobile cations and negatively charged vacancies in the electrolyte. The positive electrode’s incoming electrons tunnel through the quantum triangular barrier formed by the EDLC that equalizes its electrochemical potential of the electrolyte with the electrochemical potential of the positive electrode; each tunneling electron reduces a Li⁺ into Li⁰. The dipoles help to keep the ions confined at the interfaces

https://link.springer.com/article/10.1186/s41313-018-0014-8

Could someone make comments about this tunneling?

Quote

In our cells in (Braga et al. 2017), the plated lithium in contact with the positive electrode equalizes its electrochemical potential with that of the carbon, which is equalized with the electrochemical potential of the S₈. Therefore, the electrochemical potential of the lithium plated on the positive electrode is not equal to the chemical potential of the negative-electrode lithium

Not clearly understood how Lithium can equalize its electrochemical potential with either Carbon or Sulfur without making any chemical bonds with them. Is it possible?

The video I watched left you with the impression that you could charge your electric car glass battery in 60 seconds and it could travel 1000 miles on one charge. Seems that Physics would say the battery would overheat big time if you could push that many amps into it in 60 seconds.   Hmmm.  Doesn't sound right to me.

[Blockhart]

What determines the charge rate us how fast a battery will accept current, without overheating or degrading. Kind if like filling a water tank. You can use a bucket or a firehose. Will the tank hold up to the force of the firehose? You can empty the tank by a small valve or dump it out all at once.

The same analogy fits batteries. The discharge rate is basically determined by the resistance of the load put across it. Anyone who has left their headlights on overnight knows about this. A dome light will not give you a dead battery in the morning.

There are others internal conditions in the battery that come into play, but this is the basics of the charge-discharge rate comparison.
