      I don't think concrete structures are really designed to last hundreds of years: 50 to 100 is more reasonable - sometimes less. However, this might be to the benefit of concrete battery technology since new tech would be incorporated in to new structures. Concrete is now recycled and all this extra metal would have to be considered during the grinding and recycling. Not a huge deal, you would think

    Some possible problems that popped up in my head:
    * How much does it complicate the cement pouring practices that are used today? (Might making cement bricks and using those in the walls be a better idea?)
    * How do the anodes, cathodes, and additional add-ins affect the structural integrity of the cement?
    * What happens during a critical failure of one of these batteries and is that something you'd accept happening inside your walls?
    * (On a lesser note) I imagine this would make it close to impossible for WiFi signals to get through the walls.

      And the very fact that there are questions such as these tells me that there is no way this technology is being adopted any time soon. Why would construction companies take on this risk with little or no benefit to themselves. The problem of storage for renewables is a problem for utilities not construction firms. Possibly utilities could sponsor the technology, but why would they do that when there are solutions available that are 100% under their control?

  • @Xero1of1

    One of the reasons why modern concrete bridges need to be replaced every 30-40 years is because of a redox reaction. The iron/steel rebar within the concrete starts to rust which expands in volume as it does so. This expansion, especially when combined with colder temperature or wetter climates causes the concrete to crack which allows more moisture in which then increases the redox reaction even more. The fact that this cement is based upon a redox reaction worries me. How long with the concrete last? Even if the concrete lasts, how long will it remain operational as a battery? I think this requires a massive amount of study and further development before it can be considered a viable alternative. Concrete itself, without the rebar, can last a thousand years or more if you get the right mix and don't add anything that can rust. The Colosseum in Rome is a prime example of this.
    What would be very useful is if we can find a building method that uses different materials that when combined, can create an energy storage system. The more pure these materials (granite for example) then the longer it will last. Granite can last tens of thousands of years, and as a building material, can be extraordinarily strong.

      Putting a negative voltage on the iron should make it less likely to rust.
      There may be an alloy we could use for the iron that would resist rusting without costing too much.

      That was exactly my thought - like stories of peoples galvanized plumbing suddenly ALL going bad at the same time. IMO, this was most likely due to the addition of cable TV (remember grounding incoming cable to a water pipe?) Or even the addition of lawn chemicals watered in by sprinklers. We all know that galvanized was a bad idea, but does anyone know exactly why it randomly caused so many problems so suddenly. Concrete is already becoming a trillion dollar issue and now they want to make it subject to electric fields? What if my cell carrier installs a new localized transmitter up the street - or if the city moves my power lines under ground - or if we're having a bad solar flare day. What do you do when you live on the 7th floor of a 17 floor eco building with a koi pond on the roof and grass on the walls and a guy with a clip board stops by to say you have to move out for 18-30 months while they "fix" it?

    Many people had this idea over decades, myself included. The ACTUAL problems are not found in the cement composition that much, but in how to mitigate the problems arised from moisture entering the concrete and galvanic corrosion of the steel re-enforcement, even using it as a cathode or anode material without compromising structural integrity. In plain English if we can use the steel inside the concrete as the cathode and the cement itself as an anode, we will have giant batteries and turn ANY concrete construction into a giant battery. Although I highly doubt it would be a good idea to constantly depleting the metal in the re-enforcement, it may be possible to at least isolate it and use doping material inside the mix to facilitate the ion exchange. Moisture will be the #1 problem to tackle. Even the best concrete always absorbs some moisture, especially when it is underground in the a building's foundation. Engineers even use special ion-exchange plugs throughout the constrction to mitigate the galvanic corrosion, and given the fact that most large cities are near the sea, the problem is even bigger.

      well i'd take anything said by someone who gives energy density of a battery in Wh/m² (or Wh/ft²) with about 5 truckloads of salt.
      batteries tend to be 3 dimensional which makes this a really useless metric for any purpose (other than showing it in a youtube video).
      to prove the point: lithium ion batteries have more than 250000000 wh/m² (if your battery is 1000m high)
      not to mention that the resin between the layers probably messes up your overall strength so badly that you could never use it as structural material anyway.

    True. Until the house settles and the cement cracks, or somebody decides to hang a picture frame or a water pipe bursts and the water soaks into all the wonderfully porous cement.
    Or the myriad different ways poorly maintained houses can degrade, which realistically is all of them. Generally people don't do maintenance until AFTER the damage begins to show.
    Also fires happen, earthquakes, extreme weather events etc etc.

In general electrons stay in the same place unless there is also an ion flow(like from the cathode to the anode *within* a battery). There is some actual electron flow in circuits, but it is so slow that it is only measured in semiconductors(critical part of how they work).
      On a side note, if you want to look up how to calculate the flow of electrons, it is called the drift flow. It is usually measured in micrometers/second. Also, it oscillates in AC current, so electrons usually travel nowhere very slowly.

      Anywhere that has access to a sustainable supply of timber should be doing their best to build everything out of wood. And that's just for the environmental concerns of the other options. Concrete is the most destructive building material, wood the least destructive.
      Wood does fine in earthquakes too, if it's properly designed for it (although you'll probably get some cracks in your sheetrock). California has almost never had problems with wood houses collapsing during earthquakes. It's always the concrete and steel stuff that collapses. Even in San Francisco's 1906 earthquake where we didnt know we needed to build for earthquakes yet, most of the wood structures remained standing. That's a small part of why the fire raged so hard immediately after the earthquake.
      edit: Notable exception to wood doing fine in earthquakes is the 1989 Loma Prieta earthquake. There were a lot of wood apartments in the city that did collapse, but that's generally attributed to the construction trend at the time of completely gutting the structure from the bottom floor to put parking there. In other words, buildings that were so poorly designed they stood no chance to survive anything more extreme than a mild breeze. Traditionally designed houses in the suburbs did just fine.

The crystals that make Portland cement turn into a strong solid have water as part of their structure.

    My main question while watching this video is that how do we know that the electrical charge within the cement may not weaken it over time? As ubiquitous as cement is and as ideal as the solution, I still have concerns. If the cement is used as the insulator, wouldn't the electrical charge by the plates rapidly corrode the rebar embedded within cement (as rebar has a high iron content). If one keeps it above ground level then in Northern climates it might be feasible, but where it snows new houses & building are subject to cracking (no matter how new) due to freeze/thaw cycles as well as ground settling; we're not even considering vibrations from other sources. Cracking in cement always leads to moisture seeping in possibly shorting out the circuit. I would imagine separate circuits would be necessary to avoid this sort of thing but this would definitely lead to increased costs if you had to pour sections separately as opposed to the current methodology. I think you've covered many other battery types which have been far superior in concept and who knows maybe sometime soon we will see one of these new types of batteries or a combination of various concepts be the solution to the ever increasing need for energy.

    • @tippyc2
      @tippyc2 Před 2 lety +4

  • @sicko_the_ew
    @sicko_the_ew Před 2 lety +2

    From what I've read so far of the comments, I think maybe the main problem with this is that it introduces possible compromises with the structural aspects of the concrete. In a list of priorities for a "battery building", the quality of the concrete in structural terms would be absolutely first. But then, as you have pointed out, the system opens up the possibility of buildings that "self-report" faults early on. And if it's already established that it doesn't compromise the structural properties, I suppose this point doesn't hold, either.
    IDK, so for now it's worth keeping the idea around. No need to hastily accept or discard it.
    I suppose, too, that one could probably split the concrete parts of a building into "structural" and "non-structural" ("load-bearing" is the term I think I've heard engineers using?). If your concrete battery is not expected to make any critical contribution to keeping the building from going horizontal, it's just another kind of "pane of glass" - but perhaps a "pane of glass" that resists fire better, or makes breaking in difficult. With that in mind, it might even be worth trying to make them as light as possible, and push all their contributions to the strength of a building onto load bearing members, independent of them?

    We are better off using the buildings and housing we already have as "batteries". Using them to store (thermal) energy when it's abundant in the form of increased or decreased temps and letting them return towards the mean when energy is no so abundant. Obviously having good thermal insulation improves the "battery". Example: Using solar energy to slightly over-cool or over-heat during the day while the sun is shining by say 3 degrees and letting the interior temp swing back the other direction at night when solar energy is not being created. The perceived comfort disruption to us is fairly minimal and the change is gradual so it's hardly noticeable. You don't even have to generate your own electricity for this to be a large-scale benefit, doing the same on-grid reduces the strain and levels off power production around the clock for energy providers. All it takes is a programable thermostat or someone willing to manually control the thermostat 2x a day.

    Problem: cement and concrete when saturated or even surface wet is conductive, which would short out the battery and could electrocute a person. Likely not with a lethal voltage, but the amperage would burn the flesh at the contact point. Concrete and cement are listed as conductive flooring under electrical code because of the danger when it gets wet. The low voltage is the only way this could be safe, but rebar would become part of the circuit and could become part of a circuit when equipment is anchored to the concrete. Some electrical code would need to be written for this to be used.

      Also I know that at least in lithium ion batteries the charge carrying lithium ions in the electrolyte plate on the surfaces of the two electrodes over the battery life.

    I can't imagine this would work for buildings anyway, the constant battery activity would degrade the concrete too quickly. There's two mechanisms that will break down the concrete: volumetric expansion of metal oxides in the battery components, and heat cycling during charge/discharge, both of which will lead to microcracking of the concrete. Potentially there could be decomposition of the actual cement bonds as well. And if there's any water being electrolyzed by the process, that would definitely degrade the hydrated cement, and you might even see hydrogen embrittlement of the reinforcing steel as well.

    Frankly, the best use of concrete for energy storage is it's weight. Energy lifts the concrete to store potential energy, and we extract the energy with the kinetic energy of lowering it under control. Make a table, put a ton of concrete on it (not that much concrete), use a motor to lift it to store energy. Use ratcheting to hold it until needed. When energy is required, use a generator to extract the energy. This mechanism can be made to hold an entire building (they already do this with seismic table/bearings), if you wanted a city-block sized battery.

Most new homes do have the foundations with concrete however, I'm not sure how ground water will effect it or if the amount of storage will justify the extra cost in residential construction. So the tech is really only meaningful in commercial buildings and possibly only poured concrete construction. This means upfront cost and time before payback will be the determining factor.

    there was some book, i forget which, i read back in the late 90s.. it talked about how the CIA/FBI would plant bugs- cameras, mics, transmitters. they would take a zinc and steel nail, nail it into a brick of the building, wet the brick and seal it. it would stay a battery for weeks and weeks, running the equipment they needed. this was the late 1970s the book was talking about and the electronics only needed a few volts.

    As long as it's not bad for your health this can be revolutionary. Even if the energy density is garbage you still need to build houses and right now concrete is the go-to material. Might as well use the otherwise static walls for something else too.
