Heros Temple Doors Technical After Effects Animation

[Jonjammin]

The earliest steam engines worked on the contraction of air rather than the expansion of it. While visiting one of these early steam engines in Wales, Fred Dibnah went on to make a scale model of a temple that used the heat of the sun on it's roof to create suction which opened the temple doors.

In reality it does not work.

@the13er why not?

@NorcanDiaboli

Hot air isn`t good pusher, because of its compressability. To push the water out it need pretty much power. Steam is maybe able to do it, not air.

[NorcanDiaboli]

@the13er hmm... actually, since the siphon makes it an absolute equilibrium, it requires very little force to push the water out, and the water-level in both containers keep at the same level throuhgout the running-time, which i think would make it possible...

[the13er]

@NorcanDiaboli

Still the power of hot air is almost zero in this case.

The system looks very 18th century -- theoretically possible, practically no.

[NorcanDiaboli]

@the13er I think the guys who made this, in ancient alexandria, would be flattered by you comparing them to something as modern as 18th century...

@the13er Air, one of many forms of energy, capable of work and, thus able to generate power, will expand in heat. The amount of energy created in this application, depends on the size of the vessel. A larger vessel, would inhabit more air to expand and pressurize. Once the heated air cools, the pressurized vessel works as a natural vacuum. Ironically, the hot air balloon was created in the 18th century, same application. Otherwise, this is ancient Greek, ingenuity.

yyy

[Slapthestickcomedies]

that is sweet how that works... i want to build a real one.

uhhhh
