heat batteries : "meet the future" paul newman

[rampart]

this guy is storing industrial levels of electricity in refractory brick.

it seems energy can be stored (at scale ) in bricks at 1500C

replacing lithium batteries . so afghans , chileans, and other inconvenient people can relax and those of us worried about disposal , well, bricks are great londfill.

The issue is you lose the whole point of photovoltaics in having to transfer electricity INTO heat, and then back again when you need it.

Also most of the literature I've read talks about DOING this in the future, not about any existing large systems.

You realize how much energy it takes to produce 1500° Celsius?

most pottery is fired in a kiln at 1000 -1200 C i need to look up the steel forge, probably a little higher?

these are extremely common iron age technologies attainable in several interesting ways, including focused sunlight, waste heat from boilers and such, forced air, geothermal, etcetcetc.

the clip states the brick loses only 2% per day (i wouldn't trust a lead acid battery to start my car if it had been sitting idle off charge for weeks at a time either. certainly a flywheel loses more than 2%/day in the moving parts.

now, where do we put these huge piles of bricks where they won;t throw off the balance of the earths rotation?

thinking about 2%/day. that must require huge piles of bricks packed for minimum, surface area.

perhaps vesuvius can be modeled as a pile of refactort brick and store geothermal heat to power naples (about 3 mollion people if i remember .) (just over 3 million. steel melts at 1350-1550 C.depends on carbon/alloys?) )

or why not just think big. the earths core is about 5200 C. why not model the entire thing as a pile of bricks?

Great, like lithium batteries they will explode. I already have flashbacks of watching Electric Vehicles exploding from the overheating lithium batteries.

i found one of the vaporizer things out on the sidewa;k recently and decided to9 take it apart and see how it worked.

when i hit the battery the damn thing went up like a flare and would not go our for 10 or 15 min. the thought of a car doing that,,,,, how are they insurable?:

If you're going solar, you don't need 15% efficient photovoltaics. But there are a lot of other waste heat sources you can tap into

inefficiency generates waste heat waste heat is an incredibly underutilized resource. all kinds of directions for heat exchanger design with new materuals and processes.

i'm thinking about focused solar as a heating source, perhaps for boiling water. the parabolic mirror i used for grilling last summer worked fine until the rib eyes began to drip on the surface............ not my best bar bq

The great majority of our energy needs is HEAT. Storing waste heat for later needs is underutilized technology.

There are ways to store the summer heat for winter heating. One method is nearly 100% efficient (zeolite). Sand batteries and brick are a low tech solution

 

[Carl in Michigan]

A little more about zeolite:

Blowing moist air over tanks of this stuff will generate a lot of heat. This will continue until the zeolite becomes thoroughly saturated. You can do this all winter
In the summertime you can use the heat of the summer sun to dry the stuff out. Once all the water has been driven out, you can reuse it to heat your home next winter!

i like the way this is going. i do not ever see an end to the need for fossil fuel, but maybe in the not so distant future that demand can be reduced.

That is until we inevitably run out.

Then why use oil to build solar panels and wind turbines

You mean if democrats give speeches over this stuff

I am pro oil and pro coal.

I am pro oil and pro coal.

My post is not negative, solar and wind require oil. We need to point that out.

We can reduce the demand by not building solar panels and wind turbines

 

[Carl in Michigan]

I'm pro nuke pro solar, pro wind, pro hydrogen. There are many possibilities.

You can cool your house in the summer at zero expense. You can heat your home in the winter at nearly zero cost.

You have to open your mind to the many possibilities out there.
