Let me get something straight: these guys are essentially proposing a biodigester that instead of producing methane and CO2, produces hydrogen and CO2. Right?

Granted I've seen that Hydrogen ICEs can run at exceptionally high thermal efficiencies (43% comes to mind), is that really worth the headache of having to deal with cross contamination from your (organic) input?

One would need to have aerstanding of the productivity of the original organism.
The safety or risk of environmental escape needs very careful analysis and these sorts of matters are probably outside of general understanding.
But if the first 3 golden rules ,safety safety safety, are addressed.
41 times or 14,100 % above the wild strain.
If these sorts of figures can be safely applied that would make for efficiency undreamed of in most other areas.
The value of such numbers could have an important part to play and I tend to see merit in comparing the potential harmful effects against the known damages we are facing now.

oops 4,100% sounds better.
also seen in context this is an indication of the power (for good or harm) of this new science.

I hope that they have safety protocols on something like this. Just because they can do this in a lab does not mean that they should.

Up 141 times indicates an increase in efficiency, and is certainly good progress, but does not indicate a good efficiency. Just as likely the initial efficiency was abysmal.

Could someone explain the following please?

"In addition, the hydrogen yield from glucose was increased by 50%, and there was threefold higher hydrogen production from glucose with this strain."

Note that this hydrogen pathway requires glucose as a feedstock. There are plenty of naturally occurring bacteria that can produce methane from non-woody cellulosic waste. IFF you're going to use a gaseous fuel for mobile applications, why keep banging your head against the wall in pursuit of hydrogen. It just doesn't make sense.

All I could guess is grant money. At Universities, they know what is most likely to get the money, so they write their proposals accordingly.

This is why it is important who is President and the Governors of states in the U.S. They set the priorities for their budgets and if hydrogen is the big deal, that is where the money goes.

sjc,
the figureheads in these political offices do little more today than take orders. The world you experience via media and online is little more than a bumbling simulation of life. What does make a difference is genuine concern and outspokenness in support of sustainable living.

Genuine - not fabricated.

Where is the glucose going to come from?

I'm thinking its the formic acid feed they are exited about and they allude to the possibility of running an average east coast household on just 8 kilos ~litres of the stuff.
Thats a lot of vitaminB.
the efficiency gains would then be 41,000%.
It does seem like of a low base tough.

sir your invention is great i want to know that from some amout of (i.e.1 k.g.) glucose the energy production? And this type of hydrogen production is dangereous or not And how can we use it in car .

Hello:

I graduate of the Acayucan Tecnolologycal Institute, actually do my titulation project named HYDROGEN PRODUCTION BY E. COLI. I need your help for recopilation of information than can help me in this work. I desires meet with this paper and to get my Title professional as soon as possible. Can i help me please?
