Nope. Only a scientifically illiterate moron treats heat as energy.

The sun converts chemical energy to a broad spectrum of electromagnetic energy.
A stove has a large amount of thermal energy to transfer to other matter via conduction
A toaster accomplishes the same but via radiance (with some convection).
Gasoline is chemical energy waiting to be converted.
Fire is combustion, the conversion of chemical energy into thermal energy.

Heat is a flow of thermal energy from one body of matter to another and is a measure of power, i.e. watts. Heat is NOT a form of energy and is not measured in joules.

Yes heat is energy,

Everyday Examples of Heat Energy
There are three basic ways to transfer heat energy:

Lol the heat sink and fan connected to your computer cpu transfers heat energy thru a combination of passive radiation and active cooling. The use of thermal paste is recommended to create a stronger bond between the cpu and heat sink in order to facilitate better heat transfer.

I have no idea why you are pretending to be ignorant, however if this is your chosen life, you are making Snowden into a genius

Nope. Heat is not energy. Heat is not transferred anywhere. BTW, I have no fan on the heatsink. The system is liquid cooled.

Active cooling...just like most car engines (though I don't use glycol in the coolant, since it's not necessary).

Heat doesn't transfer. Not the purpose of thermal paste.

See in your trollish and delusional mind you believe that you are arguing with me when you are actually arguing with the second law of thermodynamics.

https://www.grc.nasa.gov/www/k-12/rocket/thermo2.html

Thermodynamics is a branch of physics which deals with the energy and work of a system. Thermodynamics deals only with the large scale response of a system which we can observe and measure in experiments. In rocket science, the thermodynamics of a gas obviously plays an important role in the analysis of propulsion systems but also in the understanding of high speed flows. The first law of thermodynamics defines the relationship between the various forms of energy present in a system (kinetic and potential), the work which the system performs and the transfer of heat. The first law states that energy is conserved in all thermodynamic processes.

We can imagine thermodynamic processes which conserve energy but which never occur in nature. For example, if we bring a hot object into contact with a cold object, we observe that the hot object cools down and the cold object heats up until an equilibrium is reached. The transfer of heat goes from the hot object to the cold object. We can imagine a system, however, in which the heat is instead transferred from the cold object to the hot object, and such a system does not violate the first law of thermodynamics. The cold object gets colder and the hot object gets hotter, but energy is conserved. Obviously we don't encounter such a system in nature and to explain this and similar observations, thermodynamicists proposed a second law of thermodynamics. Clasius, Kelvin, and Carnot proposed various forms of the second law to describe the particular physics problem that each was studying. The description of the second law stated on this slide was taken from Halliday and Resnick's textbook, "Physics". It begins with the definition of a new state variable called entropy. Entropy has a variety of physical interpretations, including the statistical disorder of the system, but for our purposes, let us consider entropy to be just another property of the system, like enthalpy or temperature.

The second law states that there exists a useful state variable called entropy S. The change in entropy delta S is equal to the heat transfer delta Q divided by the temperature T.

So if you really feel the need to argue that heat is not energy you should tell NASA how wrong that they are.

Yawn

Have you frustrated yourself totally yet?

No, it isn't. Thermodynamics is a set of theories concerning thermal energy (and in some cases, energy in general).

Nope. Nothing large is required about the scale.

Systems do not perform work. Work also has a specific definition.

This is more or less correct.

Energy conservation occurs in nature. There has never been an example where energy was not conserved.
Swan wrote:

This is energy dissipation, in keeping with the 2nd law of thermodynamics and the 0th law of thermodynamics.

Heat flows from hot to cold. Heat is energy dissipation. It is not energy.

It does, however, violate the 2nd law of thermodynamics.

Can you post your version of the second law of thermodynamics that details how heat is not energy? Or are you going to continue proving that you are schizophrenic?

My guess is the latter.

Why this landing technique is the dumbest one? Do you say so because prototypes often blow up? Then it would be best if you went deeper into engineering and aerospace engineering. I want you to know that Falcon rockets also blew up at first, but now they are widely used for delivering payloads into different orbits. Why don't you like SpaceX?

There is only one 2nd law of thermodynamics. I don't somehow have my own version.

Can you post the part of the second law of thermodynamics that details the flow/energy equivalence?

Or are you going to continue proving that you are schizophrenic?

My guess is the latter.

There is only one 2nd law of thermodynamics: e(t+1) >= e(t) where 'e' is entropy and 't' is time. This means any concentration of energy, like thermal energy, must dissipate. Such energy will always flow from hot to cold. This is called 'heat'. It is the flow of thermal energy, not thermal energy itself.

This has already been answered for you numerous times. I have answered it AGAIN for you. Stop asking the same question over and over. It has been answered. RQAA.

Because it's a private corporation, probably.

There were people during the NASA Moon launch days that figured it was all a tremendous waste of money to put some guy named 'Doke' on the Moon.

There are people that are still afraid of their microwave ovens.

There are people that are still afraid of power lines, jet engines, cell phones, computers, and cars.

You will find detractors everywhere.
