This 2,000-year-old toy was a steam engine.
Heron of Alexandria described it in the 1st century AD. Water boils, steam shoots out of two bent nozzles, and the sphere spins. Then nobody put it to work for about 1,600 years.
I asked Opus 5.5 to rebuild it in 3D:
→ the fire heats the water, the pressure builds, the sphere spins up
→ steam jets that push the sphere the opposite way, like a real reaction turbine
→ live readout: water temperature, steam, rpm
→ one html file, three.js, no 3D models

这件 2000 年前的“玩具”,其实是一台蒸汽机。
公元 1 世纪,亚历山大港的希罗(Heron of Alexandria)就描述过它:水被烧开,蒸汽从两根弯管喷出,球体随之旋转。然而在此后的约 1600 年里,却没人真正用它来干活。
我让 Opus 5.5 用 3D 把它复刻了出来:
→ 火焰加热水,压力不断积聚,球体开始加速旋转
→ 蒸汽喷射产生反作用力推动球体反向转动,原理和真正的反作用式汽轮机一模一样
→ 实时数据面板:水温、蒸汽状态、转速(rpm)一目了然
→ 只需一个 html 文件,基于 three.js,无需任何 3D 模型
