Still not with water tight walls yet and the roof is with water shield paper. Waiting to see if all plywood wire on by weekend.

Rain delayed work on house rebuild and improvement with more materials being ordered for Tuesday use followed by more deliveries to do roof and more to seal it up before more weather happens.

I did login to newmars forum and new and it resets newmars forum not allowing for a day to be able to login but seemed ok. Found a way to access accounts on old cell with wifi tethering for now.

I did visit from the link and you are correct most things seem there from a data base stand point.
#14 Re: Science, Technology, and Astronomy » Fluidized Sand Thermal Energy Storage » 2024-10-05 18:02:31
I take the word sand as sand being crushed grains that are fine from earth soils and rock. The pipes extend in through the sand and come out the other side. The heat is coming from exhaust heat or from heated air or any other working fliud, or gas that is pumped through the system.
Magaldi's website states that its thermal unit is sustainable, made with silica sand and steel.
charging, storing, and discharging
To discharge, the heat exchanger reverses, releasing superheated steam at up to 752 degrees Fahrenheit.

This is the system that I described for solar concentrated with antifreeze heat exchanger embedded in the sand so that heat can be taken out later for heating.

Successful Vulcan launch early Friday would unlock lucrative future for ULA
Vulcan takes two BE-4 engines, which along with up to six solid rocket boosters provided by Northrop Grumman, give Vulcan more power than either Atlas V or the now retired Delta IV Heavy, with 3.6 million pounds of thrust on liftoff.

We have talked about sand but adding liquid now creates internal tank storage pressure. Sand battery was discussed in the Geothermal and Geothermal Battery (Changed Title 12/21/23) a Void started topic.

Bought burial plots Monday which didn't include opening and closing which happened today. I am quite tired but I think she would have been happy. They didn't find out full term baby girl but moved her headstone next to her grave. Son from Texas got here late last night due to change in connector flight redirect. Spent time yesterday in the rain continuing the shed build with son that came down from Littleton.

I have sad news to let all on the forum that know of my wife's conditions as she has passed today with her 3 sons that live still at home while I was away at work.

Since working in units of meter is called for then the Ton is a metric ton or 1,000 kg which is 1,000 liters.
Storage is the units in a stagnant or none moving state.
The pipe sizes are also critical for the flow rates desired not only to maintain filling the tanks but for also pumping them to the top once more to close the loop.
Try to fill a 1-liter bottle in 1-sec. from the water facet and then you have a comparison point as that tap is at 40 to 50 psi. or https://www.aqua-calc.com/convert/press … -kilopasca https://calculatorpack.com/water-pressure-calculator/
Power turbin water exits out the bottom of the unit so its going to be mounted at the top of the down hill tank.
this shows the water re-entering the stream after exiting the pump
This is a turbine that one can build as a DYI if that is your choices.
Power generated would connect to a battery system and be draw out of it by the pump is we are unable to build a Ram pump.
otherwise, the battery then connects to the invertor to make 60 hz voltage for use.

The storage is not a number but a variable that is determined based on the tank volumes, water amount, internal and external capability for pressure and vacuum as Caliban has already indicated due to implosion and explosion of the tanks and piping due to those levels.
So, you must decide on the level of work that must be produced to determine those values in the above statement. You must determine the power levels for the pump and generator in order to size all other aspects of a design storage and use.
One can make the storage the size of a walnut under extreme pressures or vacuum, or you can have a mountain size unit will be minimal of those.
The original numbers have already been given and they produce very little energy.
You must also include Gravity Energy Storage as they are part of the energy system by default.
We are still talking about the most efficient form of storage and conversion rate for Electricity, Work, and Power
Summary of Force, Work and Power
Force = Energy applied to an object(Measured in Newtons).
Work = Force X Distance, or the amount of heat transferred (Measured in Joules or calories).
Power = Work/Time (Measured in Watts)
Various Energy Units
1 calorie (thermochemical) = 4.184 J
1 Btu = 251.9958 calories
1 Btu (thermochemical) = 1054.35 J
1 kilowatt-hour (kWh) = 3.6 x 106 J
1 kilowatt-hour (kWh) = 3412 Btu (IT)
1 therm = 100,000 Btu
1 electron-volt = 1.6022 x 10-19 J

https://en.wikipedia.org/wiki/Working_fluid
generator type for the working fluid determines inlet rate from the volume
This is also where we get into how much power wattage can I get for how long of a duration before refilling the volume.
Pressure control is achieved in hydraulic systems by metering the flow of a fluid into or out of a constrained volume to create force such as a jack for an automobile.

A pump adds energy to oil in any of the three ways, as described by Bernoulli’s equation:
Hydraulics pneumatics Com Sites Hydraulics pneumatics com Files Dec mc Eq1
where P is the pressure,
ρ is the density,
v is the velocity,
g is the acceleration due to gravity, and
h is the elevation.
More equations on the page
https://www.machinerylubrication.com/Re … re-vs-flow
Of course, this is moving the fluid to make pressure from the reservoir to the location to be moved.
Sensing functions that are computer controller-ed used to produce a response for more or less power seems to be good to have.
While I am thinking about gravity and water as the mass that we can make use of.
https://www.micro-hydro-power.com/water-turbines.htm
Power (watts) = Head (m) x Flow (litres/sec) x 9.81 (gravitational constant ‘g’) A typical water to wire efficiency is around 70%, so you should multiply the result by 0.7 to get the actual amount of electricity that you can expect from the site.
https://www.builditsolar.com/Projects/H … fRiver.htm
Power = (1/2)(Turbine Efficiency) (Water Density) (Turbine Flow Area) (Water Velocity)^3
Normally the mass is what will cause the turbine to move so knowing the amount and time is a flow rate.
Rotation is required and that is torque for the turbine.
Of course, when you need RPM's we are looking at that flow rate as it relates to the torque values.
https://www.studysmarter.us/explanation … al-motion/
https://en.wikipedia.org/wiki/Torque
Power in rotational systems (torque and frequency of a rotation)-527.png)
power generation from the top to the bottom means we want to make 2 -3 times what we would use. So I am looking at the 3kw turbine as it would cost less than $400 on ebay turbine

Store of pressure or is defendant on size of chamber and period that measurement is done.

So off grid water power creators use an old washing machine motor rewound to producr 600 w at 24 v like this unit
