Hydrogen ping!.........

“Hydrogen can be easily converted to electrical and mechanical energy without any production of carbon dioxide,”

But isn't water vapor an even bigger greenhouse gas?

... cellulose-based high-temperature hydrogen production process ...

The high temperature part of this may still mean that production of hydrogen still consumes more energy that the hydrogen product provides.

If the scientists are good, the by-product will be beer.

“Hydrogen can be easily converted to electrical and mechanical energy without any production of carbon dioxide,”

When the cellulose is broken down to produce the hydrogen, what happens to the carbon? For every Kilogram of hydrogen in cellulose, there is 7.2 kg of carbon.

They found Desulfurococcus fermentans in the Uzon Caldera on the Kamchatka Peninsula, an isolated spit of land in eastern Siberia

Allow me to be the first to link this to the Tunguska Event of 1908.

Now suppose we produce Hydrogen by the quadzillion cubic foot per year. Some of that Hydrogen is going to escape, and go into the upper reaches of the atmosphere and even be lost into space, since it is so light. Then the oxygen that would normally be bound to that hydrogen will be left sitting around with nothing to do.

So, what is going to have a greater effect on life and the environment, elevated inert CO2 or hightly reactive Oxygen?

Wow.

This is a highly significant finding.

It isn’t hydrogen fusion, but it might be entertaining trying to build hydrogen farms inside volcanoes.

“Hydrogen can be easily converted to electrical and mechanical energy without any production of carbon dioxide,”

No it just produces water vapor.... Which is the stronger ‘greenhouse agent’ again?

[Born Conservative]

Hydrogen economy? That’s probably a long ways off.

Interesting article in the current “Skeptic” magazine.

Not available online, and I read it 2 months ago, but basically it said that it takes more energy to produce it than Hydrogen provides, and that the vehicle to transport it is something like 10,000 lbs, and can carry 1,000 lbs of Hydrogen. That’s not to say that the technology isn’t GOING to be developed, but it may be a while.

I can see some future Presidential candidate bemoaning our addiction to bacteria farts.
