putt-putt boat fusion

Post by Richard Hull » Mon Nov 05, 2018 9:52 pm

Many here, over the years, have heard me refer to "putt-putt boat" fusion regarding the NIF effort and all other fusion pulsed efforts to explode a miniature hydrogen bomb using terawatt lasers or pulsed action fusion of any kind. I have considered it like trying to power a city off of regularly timed lightning strokes.

The putt-putt board was a real little bathtub tin toy of my youth. It was commonly available at all five and dime stores for about 10 cents in the 40s and 50's. (cheap Japanese made, post war product) The boats used a candle in a pan to heat water in pipes within the boat to start to flash heat steam to create a familiar "putt, putt, putt" sound as a slug of water hit the super hot part of the pipe, flashed to steam and another cold slug would take its place to blast to steam again, and again. It relied on the non-compressible nature of water in the pipe to force the steam out the back and push the boat forward. The thin, folded, sheet metal of the boat's construction featured razor sharp edges seemingly designed to slash little hands as they installed the piping and lit candle can in the cramped miniature interior. (note: some assembly required. Band-aids and Merthiolate not included).

Pick this 10 cent boat up, (now treasured collectible), on e-bay for the paltry sum of $70.00.

Here are two images of that little toy that inspired my comparison to explode-explode-again fusion.

The Japanese manufacturing an American PT boat is rather ironic; not unlike NIF with its claims that it would do break even fusion research rather than their real reason to exist - aid development of new weapons (they failed in that effort too.) Wrong laser, wrong illumination methodology,and wrong thinking all added up to a wasted program that took all direct drive fusion in this country down with it.

Growing up just after WWII ended, the US was flooded by cheap, often poorly made, Japanese goods. As they struggled to recover, we referred to such items as "cheap Japanese junk" with a smirk on our faces. Well, they showed us... They came to lead the world in the best electronic consumer goods and in the late 70's taught us how to make useful, efficient and reliable automobiles. Conquered in war, they became winners in many economic battles since. Their goods are still among the finest on earth. I always buy Makita over US made Delta power tools due to long term performance and Makita's unwillingness to cut corners to achieve a price point.

The Japanese fusion efforts are often bold and unusual. They still pursue not only IEC, but limited LENR work. They also contribute to ITER (hot fusion)

Try Panasonic power tools, they blow Makita out of the water.

Lately I've seen Hitachi power tools appearing in the hardware store.

I had putt-putt boats as a kid, but they were more like gurgle-gurgle boats, and very slow. The engine was made not of sheet metal but of thin-wall copper tubing bent in a coil. They were considered a thing to make yourself.

Hitachi makes some very nice stuff as well. I have one of their older 3/8" corded hand drills. It is geared like a 1/2' drill. I actually put on a 1/2" chuck on it instead and use that for anything I need slow speed and a ton of torque. Killed the trigger once but a replacement was easy enough to get.

All the little boats had copper boiler piping, either coiled or zig-zaged over the heat source. The boat itself was thin, formed sheet steel.
