If I was a young guy who lived there I'd be all over that.

Most who were making history didn't know they were when they were. These few must know.Will TPTB allow it to come to fruition and unburden the people from the cost of energy? Given that the promising early results actually Can be upscale d and controlled....

Hybrid vehicles hit a max of 3% market share and are decreasing in favor of all electric.  So I would guess the trend would continue, any new tech will get a 3% market share until with more importantly a trend to total conversion to LENR tech until a tech winner is determined.  All the hybrids that have a small gas engine will convert/retrofit immediately.

Sadly, if it can't be made idiot proof, legal liabilities will keep it unavailable.
Look at lawnmowers, get off, motor dies, put in reverse, blades engaged, dies, foot on pedal or no start... your bike, you've gotta hold the brake down to get outta park on the car.

I had always driven old stuff and standards and got a job with a company truck. It sure was embarrassing asking how to put it in reverse.
My foot was Ready to hit the brake, I just didn't see why aa motionless vehicle needed for the brake pedal to be pushed.

Well, that's good news And bad news at the same time.
They either see it as promising and powerful enough to be useful or at least worthy of wasting taxpayer money on.
Hopefully they won't try to take the fact that they are working to develop it and declare it a matter of national security and halt public access and experimentation.
I'm cynical enough to envision a time when such a great boon to society would be withheld. Imagine the
Lobbying ,,,coff,coff

I don't see it made available to American s.

Missiles are now solid fueled and are quite small, they can launch out a torpedo tube now (as can a current cruise missile).     Just go into a very sharp nose incline position and fire as you get close to the surface of the water ....  the booster rocket will punch through 100 feet of water and put the missile 50 feet up into the air before the main missile engine ignites and rockets on off.

   
This is a new attack sub being built by India, note the 8 torp tubes, mounted high on the fusilage.

Our attack subs are nuclear electric, as were the Russians.   There is a new class of fuel cell electric subs being built by Norway, etc that are intended for coastal defense.   LENR electric subs would be a long range class of subs that wouldn't have to carry the weight penalty of all that fission radiation shielding.   All our subs had between 2 and four fission reactors (redundancy for maintenance, etc) but a LENR system might have readily replaceable "plug in" cores that could be changed out at sea if need be.    

Our old big boomers were built huge to hold MUCH larger long distance missiles (held vertically) as that was the size and type of the tech back then.   Also a boomer hides far far away in water that is not swept by the opposing navy, while an attack sub is close in to the combat and can pop a limited range ballistic (or a cruise) from much closer in.   Less distance, less missile is required.

We should worry about people being able to pop us from close in using much less expensive newer tech.

It ain't just subs any more, anything with 15 feet of spare deck space can do this ......   a good sized ski boat could do it, or a smuggling type boat or any large cabin cruiser could be modified to drop a hatch open and do this.   They can be air dropped from a plane, jest open the back hatch and kick 'er on out the door --- scary, ain't it?

All the tube launched ballistic missiles are actually smaller than what comes out of the torpedo tube, the torpedo casing then cocks up and rocket propels the missile up into the air where it ignites and takes off for real .....

Payload, a Hiroshima sized implosion thermonuclear device (or bigger) can be held in your two hands now.

suicide bomber with 'backpack nuke' used to be a thing in fiction, now it's doable for rills
