1. Your first article says it is propelled by an engine!

It says that a propeller is driven by an electric motor powered by batteries charged by a windmill. I did not see the word engine in it. It is just Wikipedia which is notorious for being loose with facts. Wind turbine driven ships have been around for a while as a novelty.

Maybe some pictures would help.

Absolutely, but the news is very promising in that the quest for this technology is ongoing.

Remember, JFK set in motion flight to the moon. It was accomplished.

Hand held cell phones, the Internet, space shuttle, high speed rail, computer miniaturization, artificial intelligence, Segway, Hubble telescope, deep space probe and the list goes on.

Technological advances that once boggle the mind are now reality.

Someday, this technology will be feasible on a large scale. I think it is very promising. I believe it will become a reality, probably first by the military

When you talk to some one with no imagination, this is what you’ll get. Does the saying “NECESSITY IS THE MOTHER OF INVENTION”, ring any bell with you? What I was trying to say, is that when the time comes, some one will come with an invention that will prove other people like you wrong. I’m talking about some one that will think out of the box.

"At ten cents a kilowatt-hour electricity is bargain."

Ten cents a kilowatt hour works out to about four bucks for 135,000 BTUs. That's the energy in a gallon of gasoline.

Recharging a car with electricity is about half the cost of gasoline. There is very little heat loss recharging batteries when compered with the massive heat losses associated with a an internal combustion engine. In a typical low compression engine, the thermal efficiency is only about 26%. In a highly modified engine, such as a race engine, the thermal efficiency is about 34%.

Having said that, electric cars will only be a novelty until the recharge TIME is reduced drastically. That is never going to happen with today's technology.

"Recharging a car with electricity is about half the cost of gasoline."

REAL cars need heaters when it's minus 40, air conditioners when it's plus 115 F, fuel in Death Valley and on Pikes Peak, boat trailers, car seats for kids, and more. Anyone could easily double the fuel economy of cars that don't have to do those things.

Throughout my career, I’ve utilized signal generators many times. In the video, they declare the flame measured close to 3k Fahrenheit.

Hydrogen+Oxygen flames do indeed burn very hot. It can cut through just about anything.
It is an indication of just how strong the Hydrogen-Oxygen bond is.
It's a simple table top experiment in electrolysis to split water into H₂ and O₂ and combine them again in a flame.
But you don't get any MORE energy from the flame than you put into breaking the atoms apart.

“Maybe some pictures would help.”

The video shows it clearly NOT directly into the wind but more like a 45 degree angle to the wind.
