Step 11Scaling up
What happens if you make things bigger?
For instance, If you took all the lengths in the dish and the pot and just made them twice as big?
What happens?
I have checked some of it. And here are some guidelines.
The surface area of the pot increases at the same rate as the area of the dish.
But if you double the surface area of the pot you increase the volume by about 2.8 times!
This means that twice the size of device will put exactly the same solar flux on the surface but there will be a lot more capacity inside.
I think that this means that compound parabolic solar devices will have more or less ideal sizes for specific uses.
Also this aspect, the volume increasing faster than the collecting area, might mean that 15 degree and 30 degree compound parabolic dishes will become the norm in larger units.
