Examples of cones:

This much I agree with: No point, no power

Re: Examples of Cones in nature

I think you folks mean no point, no pressure. Pressure is a unit of force divided by a unit of area, so minimal area (eg. a the point of a cone) means maximal pressure. Power is a unit of work (which is itself a unit of force times a unit of distance), divided by a unit of time, so minimal time means maximal power. Since there is no time component in a cone, its shape is not directly related to power.

Re: Examples of Cones in nature

Hi all,
I particularly like ice cream cones especially ones with a Cadbury's Flake stuck in it, along with a large dollop of 'Monkeys Blood' [ ie a lovely tasting red sauce].Makes my day .Joe.

Re: Examples of Cones in nature

Benjamin, power does imply "rate" of energy. And in this case it is power. The energy's already present, and needs to be "transfered, used, or transformed."

By decoupling - through various points - and allowing the energy to discharge, it's transfered.

And it's important to differentiate between "energy" and "power."

In physics, power is the rate at which energy is transferred, used, or transformed.
Pressure is force per unit area applied in a direction perpendicular to the surface of an object.
It's not pressure. Pressure is "applied" over an area...

Power is directed, transformed energy. It's the decoupling via the cones - that creates the "drain" that allows the energy to transform and become directed power.

Actually, you helped me clean that part up. Thanks...
