New Engine Designs

Saw it on the news today.

As I believed, and have said, hybred engines are dead end, tech speaking.

One new very promising design is mech storage, as I was advocating before. There is a nitrogen compression system that stores and released power.

The other is a system that diverts exhaust heat into the air going to the engine.

By being preheated it makes the burn more efficient, thus getting a lot more power from gas.

Both look promising. Maybe both combined?
