And we have these little electric turbo pumps, they're about the size of a Coke can.

我们有这些小型电动涡轮泵，它们大约有一个可乐罐那么大。

Now, the electric turbo pump cycle is a totally different way to pump the pellets into the rocket engine.

现在，电动涡轮泵循环是一种将颗粒泵入火箭发动机的完全不同的方式。

So we came up with a new cycle called the electric turbo pump, which we'll talk about in a moment, but we also managed to be able to 3D print these rocket engines.

所以我们想出了一个叫做电动涡轮泵的新循环，我们稍后会谈到， 但我们也设法能够 3D 打印这些火箭发动机。
