Comment Re:What the heck is RTO? (Score 1) 230

I work in this industry.

An RTO is a Regional Transmission Operator. RTOs are responsible for maintaining and operating the buik grid (wholesale level). RTOs schedule generators to run based on demand and market conditions.

Burning jet fuel, by the way, is not unconventional. It is just undesirable because of the cost. Quite often, the gas turbine generators can also be run on natural gas or on a mixture of the two fuels. It is preferable, however, to have other types of generators carrying as much of the load as possible -- steam turbines, for instance, produce much more output for the same fuel input, but can't be started/stopped quickly.

Except now all you have is a ratio of two masses, rather than an absolute quantity. What exactly would you balance the kilogram reference against?

You would use it to callibrate another mass as being a kilogram. I know this is kind of a circular problem, but that's really why the fluctuating mass is troubling, because that's supposed to be the stable benchmark, and it has proven not to be so stable.

Or do you have another method involved for determining the mass of an object used as the constant for measuring mass?

Placing two masses on a balance is the usual method . . . . and it is gravity-independent. Gravity is necessary, of course, but it only needs to be constant across the two platters of the balance.
