I read more about how goods were transported on horses and wagons and how canal boats could transport goods more cheaply, starting in Europe, then England and in the USA. Then the railroads were built and canal freight took too long compared to rail service. Much later trucks took over the hauling of most goods over land. The canal part was a gap in what I used to know about transporting goods. The best track builders were former canal workmen because a locomotive needs a track bed with little elevation change. Just like there was a "dot com bubble" (burst in 2002) there was a canal and a railroad bubble.
The railroads brought us standardized time zones.
OK, I like boring stuff related to business and finance. Business and finance has a link to pay checks. Paychecks have a link to finance and romance.

There are still lots of barges plying the canals in (Central)Europe, and there are lots of canal and river networks for them.

Petrushka, I watched several European Canal videos and boy do they have some imaginative ways to move boats between obstacles of different heights. A poster that lives west of London has a smallish canal boat as as a week-end home. On one of her posts, she said they went through a canal tunnel over a mile long. I thought WOW, that took a lot of work to dig/tunnel through the hill or mountain by hand. In the USA, there are a few sections of the Erie canal operational and there are bike-walking trails on the tow paths. The most popular canal experience is the 184.5 mile C&O Canal tow path, (no water in the canal) used by several people on bicycles. The C&O tow path connects to the GAP so you cam bike from Pittsburgh PA to Washington DC. This is not new to me but in school we were told Eli Whitney invented the cotton gin. Well, several months ago I was watching videos about the history of India. India had a way to remove the seeds from cotton a long time before Eli Whitney's time. Number 1, don't believe everything you were taught in school. Number 2, history is written by the victors. Number 3, be a life-long-learner. |

Google has been investing in a $10M project to revive cold fusion to produce cheap and clean energy. www.nature.com/articles/d41586-019-01683-9"There is no theoretical reason to expect cold fusion to be possible, and a vast amount of well-established science that says it should be impossible." But absence of evidence is not the same as evidence of absence. But being unable to rule an idea out completely does not mean there is good reason to pursue it. Google's got so much money any way. And science is fun. |

Doesn't fusion work on the sun because of a very strong gravity field pressing hydrogen atoms together? When the hydrogen atoms are pressed together it form helium and things get very hot because of the conversion. Because there are bilbions of galaxies and billions of stars in many og the galaxies, I think cold fusion would have happened in some place in the vast universe. en.wikipedia.org/wiki/Cold_fusion |

I have a loaf of bread size paper wasp nest high up on my house by the front door I bought some spray in a can to kill wasps. The spray only seems to annoy the wasps. I looked up wasp spray and one article said to try Dawn brand dish soap and water. I mixed 1 part Dawn with 1 part water. In a good spray bottle I was able to squirt the high up wasp nest and about 75 % of the wasps are dead.
A $4 can of wasp spray equaled about a 10% effective solution. A $2 spray bottle and 50 cents worth of soap was a 75% solution.
I see the wasps moved and made a new nest behind the tail lights on the car.

The wasp spray can is pressurized such that it can reach a distance over 10-20 ft away. How about your spray bottle? Wasps would love to retaliate when getting sprayed.

Ok, the whole idea as to why fusion might be desirable is to either make helium out of hydrogen -- with the aim to set free a lot of energy in the process that can then be used to generate electricity. Now, that energy gets liberated as HEAT. Cold fusion would not stay cold for many milliseconds, were it to happen. Or, otherwise, if it did not generate said energy, it would be completely pointless. {eye roll} The wannabe invention of the perpetuum mobile machine was a common pasttime years ago ...
Vice versa, there's the other version of 'cold fusion' which is the attempted conversion of lead into gold. Mostly by randomly mixing powders. If'n you're really lucky, you find a mix that goes 'boom' and makes you famous, right Mr. Schwarz? (historical reference, Mr. Schwarz was the European alchemist discoverer of gunpowder, which is hence called Schwarzpulver in German --- ironically, schwarz also means black, and it is, isn't it?!? Of course, the Koreans and the Chinese had found out about how to make gunpowder quite a few years prior).
I've seen some speculative writing about "slow fusion" - but, seriously, that doesn't make much sense to me either. So what if you can make enough energy with 'slow fusion' in 100 years to drive your electric car 100 miles down the highway?

Dunno about what exact genus of paper wasps you have over there. I have had really good success with spraying paperwasp nests with pyrethroid sprays, from 12" away, the knock-down is so fast they never even made it close to me to sting me. We get a lot of nests on our wooden retaining wall below the lawns.
On the other hand, I would not try that with the black and yellow striped 'German Wasps or Common Wasps' that have self-introduced to New Zealand, they are hardier, faster, and more 'goal oriented' than the Asian Paperwasp that we get here. Douse their nest with petrol or diesel fuel long after dark when the temperatures are down and they are drowsy (but do not set fire to it) and run like hell, and the fumes will kill them over the course of a day or two.
Alternatively, call in a beekeeper. Beekeepers hate wasps and most will be only too happy to help you out.

I don't know the genus of wasps.
1. I know we have the kind that make a cluster of cells and then a paper like igloo shaped covering.
2. Then there are wasps that make just clusters of cells behind the mirrors and light on my cars.
3. Finally I have the wasps that make small clusters of mud tunnels high up on my house.
Type 2 that make clusters of cells are the most prevalent and the ones that sting me if I am not fast enough to get away from them.
When I act with some intelligence, I go out in the very early morning when it is cool and do my eradication work.

Lots of information to find there. And it is true that cold fusion is not supported by any reluable scientist. It is also very suspect that nothing that is published on cold fusion is according to science standards. It is all vague and not controllable. Therefore nothing is publushed in reknown publications. |

Tamara68 I have read some of the information in your link several months ago. It is good to re-read it. I understand the general concepts but i do not have enough solid background when it some to the symbols that represent elements or the scientific names for some of the processes. A long time ago an engine that ran on water got my interest going so I looked for previous experiments. I wasn't buying the the water concept but H and O2 indicated there might be some truth to water being a fuel. I knew about electrolysis and water. I actually had some accidental first hand experience with car batteries on a charger and explosions. The old style electrolysis requires a lot of energy input so that put a wet blanket (decreased my interest)on things for me for a long time. Now there is a lot in the news about hydrogen powered trucks and photovoltaic cells providing the energy to convert water into hydrogen and oxygen. Anyway back to water and engines. Back in time when farm tractors were fairly new and big there were tractors that used water in the combustion process. Distillate or kerosene was low priced but also had a low power output and the tractor's engine would not start on those fuels. Some tractors had 3 fuel tanks. The tractor was started using petrol-gasoline and when the engine was warm, the gas was turned off and the kerosene was turned on. This mode didn't provide enough power so when more power was needed a secondary tract of the fuel delivery system was turned on to deliver a small amount of water to the air intake of the engine, which resulted in a little more power. A TV series "Classic Tractor Fever" and Wikipedia has examples of engines benefiting from adding a little water to the combustion process. Military aircraft have also used water to gain more power for short time periods. en.wikipedia.org/wiki/Water_injection_(engine) Only water as straight fuel is too unbelievable just as "cold fusion" does not compute in my mind. Maybe someday "not so hot" fusion might be possible. ITER fusion, yes I have also read that article at Wikipedia. I am happy to report that I am thankful for minds greater than mine and I am amazed how those better minds collaborate on a gigantic project like this and the CERN project. Now, if people could only focus on making the world a better place and give up on "my religion is better than your religion" crap and my country is better than your country and I need to kill you folks, maybe the ITER fusion project and curing cancer and major health issues might make some fast and beneficial advancements. What about "big foot?" More bunk but people seem to like myth stories. OK! Just call me "too serious." I already know I am at times. My DSMIII evaluation indicated as much. |

I know the water does not combust but it has a great ability to expand when it is heated. More expansion = more push = more power. There was a TV program (a single episode) about a nuclear-powered aircraft that I watched. It was complicated to start the process of starting the reactor and the more I watched the program the spookier it got. I also looked up different version on a nuclear engines. I researched my trip to Alaska several years ago before I went on the trip and discovered the US Air-force had a plane that crashed north of Hazelton BC, Canada. The information said the crew dropped the bomb in the pacific ocean before the plane crashed. The really scary part is this was not the only time a bomber crashed or a nuclear bomb was lost. Back to something more reasonable but still ultra hi-tech from Youtube. I posted the titles of the videos so the viewer hopefully doesn't have to endure the BS political adds.

BTW, I am still impressed with Australia's "Snowy Mountain Scheme"

Correct on all fronts Handy . British scones are typically eaten with jam & cream or cream & jam depending on whether you are from Devon or Cornwall. |
