It's a viable alternative fuel. It's not pie in the sky, it's not cold fusion.

You'll have pie in the sky when you die

It's not gonna knock your socks off, and it certainly won't be the brightest object in the sky, but it'll be easily observable with the naked eye .

Ellen had said that her mother was afraid of the ocean, that it was too cold and too big. The sky was, too, thought Annemarie. The whole world was: too cold, too big. And too cruel.

We are disappointed to have to leave, but we now have no alternative, as we no longer have the fuel resources to stay.

You don't want no pie in the sky when you die,/ You want something here on the ground while you're still around.
