I'd like to point out that this is neither a new invention, nor viable. Brown's gass, hydrogen chain reconstruction, and catalytic electrolysis have all been done to death since the 40's and never panned out.
Besides, we can already electrolyze water in Gregtech into Oxygen and Hydrogen, then burn the hydrogen. Or better than the above, add carbon to reconstruct methane. Mmm, natural gas. Wish that were viable IRL. But hey, we're working on it! (We can do it already it just costs more than the gas could ever be worth. We don't have an easy way to construct even simple hydrocarbons.)
However the UoA may be close to a way to synthetically construct nitrocarbon chains that could be used to enrich existing liquid fuels. That could be good. (Think Nitrodiesel from Gregtech, except without the glyceryl step. Also totally different, chemically accurate, and actually possible. If successful it would reduce fuel consumption 5-12% across the board for all diesels and octane-based gasoline, while giving a good 15-20% boost in energy output! All without the need for petroleum! Sometimes the answer isn't to change horses mid-stream, it's to streamline the horse.)
Edit: Further research actually shows that not only is the technology behind this 'sunfire fuel' old as hell, but even the device is! The technology was invented in 1925 and several dozen machines put into effect in 1927 and 1928 respectively. However due to the need for a catalyst (which this article doesn't mention, and believe me, it IS chemically required) it basically still needs fuel to make the fuel... at the time they used various light hydrycarbon fuels such as kerosine and propane, although methane is a more viable method (that is not yet, to my knowledge, perfected). Due to the cost and the fact fuel (albeit different fuel, fuel nonetheless) still need to be transported, any perceieved benefit is actually invalidated. It will subsequently be relegated only to remote locations where reduced transportation costs are greater than the subsequently massive cost of making this 'sunfire fuel'. It should also be noted that said 'sunfire fuel' is still NOT comparable to diesel or gasoline, having a much lower energy density (~45%, compared to ~15% for straight methane), meaning it will require roughly twice as much of said fuel to produce an equivocal amount of power compared to octane. This may result in it being unviable for use in actual vehicles, especially military ones, and more suitable for small-scale power generation such as temporary encampments. It's neat, but it's not half what it advertises. Such is usually the story for alternative fuels.
Also, another continued conclusion: Methane is God. The UK and Ireland learned this, and they're doing rather well for it, all things considered.
I was not referring to fuel applications. In GT oil is used for other things. Lubricant for example. And this might be a more proper way of obtaining oil in GT than oil berries.
