John Harrison in the 18th century spent 31 years of testing and designing the first Chronometer to tell time, and thus allow for accurate navigation at sea. He never completely won the equivalent of nearly 3 million for a life’s work in doing it.

The Chronometer revolutionized sailing and sea travel enabling England to efficiently maintain its force sea projection and eventual rise to meteoric status as the largest Empire the world has ever seen.

My wife has quantised inertia (QI) – through which she believes light can`t be converted into thrust coz she likes it in the dark.

1.3 million? Hmmmm... Chump change for something like this. They’ll be back for more $$ in no time.

Once our govt starts giving out grants for research into “theories”, it never stops. Just look at the global warming\climate change racket.

Use that magic stuff the Star Ship Enterprise used.

Lithium Crystals? Are you crazy? First we have to get to that planet that has it so we can mine some. Sheesh.

What happens when the solar pressure drops off?....or you get caught in cross currents from other stars?

“Only needs electricity’? That would make for an awful long extension cord.

Chemical rockets aren't expensive because explosives are expensive. Explosives are cheap. When I was a kid I could buy Estes solid fuel model rocket engines for less than a buck. Chemical rockets are expensive because they need so much fuel.

Apollo 11 weighed 6.8 million pounds on the gantry. Almost 6 million of that was fuel and oxidant. It burned 78 tons of fuel/ox before it cleared the gantry and 4.5 million pounds in the first 180 seconds after ignition.

If you had that weight in gasoline and a car that got 30 mpg, you could drive it about 22 million miles. The moon is only ~235,000 miles away.
