Re: [Vo]:The "customer" warehouse

Here another calculation.
1) Fill the building with ice. That is about 3.3 K tons of ice.
2) Melt it to water
3) All the energy of the plant goes to melt the ice

Result: it will take 12 days to melt of the ice. So in 1 year you will have
to do this about 30 times, for a total of 100 K tons of ice to dump the
energy into pretty demanding physical-chem reaction (conversion of ice into
water).
This assumes you can do this without taking time to dump the water and fill
the building of ice. Gnomes take care of that magically (after all you have
to have faith in Rossi and his magical powers).

Again we can do this more realistically and come up with even more
efficient processes but you can see how ridiculous are these calculations
if you take Rossi seriously.
I attach a graph of conversion of warehouses of ice per day.

Sorry the label on the graph should say "days" not hours, here a fixed

Re: [Vo]:The "customer" warehouse

[Giovanni Santostasi]

Here a simple model, the physicist way: very simplified, a lot of
assumptions but it gives a feeling of the energy and temperature involved.
An extreme case, not too realistic model but we can start with this simple
model and add more realistic physics as we go.

So this is what I assumed:
1) the building is full of water. It is not possible of course but water
has decent heat capacity so let's use it to fill the building and see what
happens
2) all the energy produced by the 1 MW plant is dumped into the water with
100 percent efficiency
3) the building is perfectly insulated, a giant ideal dewar
4) I started at 0 degrees and used calories conversion from Joule at 15
degrees (for simplicity). Starting at 20 degrees (room temperature) wold
just save a couple of days.

Again we can make a more sophisticated model but this calculation could
have been done in the head as an order of magnitude problem.

The result shown in the attached graph is that it would take about 16 days
to reach 100 degree Celsius for the entire building filled of water.

We can have fun and imagine other materials and see how long it would take
it to melt them and so on.

PS
Double check my calculations and see if they are right.

That the client is no longer in business at the end of the 350 day test,

Let's do a Fermi problem to see what is needed to get read of 1 MW 
dump in this space. By the way 1 MW can power easily 1000 houses. In 
fact, if you do the exact calculation using average US consumption per 
household you get about 9000 households.

Here a picture and information about the "customer" warehouse. It is only
6000 square feet and the height is 20 feet.

Let's do a Fermi problem to see what is needed to get read of 1 MW dump in
this space. By the way 1 MW can power easily 1000 houses. In fact, if you
do the exact calculation using average US consumption per household you get
about 9000 households.
