Its still a bit heavy for one person though, hence the proposal focusing on making it lighter. I guess I am making it an assault rifle...

Maybe. Is it really that heavy though? If one guy can move it that's excellent but two would work just fine. I think mostly it just needs to have a convenient bipod and conveniently stored ammo. We should invent removable box magazines.

E: Yeah 33 pounds loaded isn't so bad.

Alcohol is ethanol.
Wood alcohol or methanol has its own problems, it burns with out a visible flame and it's corrosive to aluminium as well as absorbing water like ethanol.

Power wise, one liter of ethanol contain 21.1 MJ, a liter of methanol 15.8 MJ, a liter of gasoline approximately 32.6 MJ and Diesel 35.86 MJ/L.

The amount of air need to burn them is ( stoichiometric ratio)
Methanol 6.42:1, Ethanol 9 : 1, Petrol 14.7 : 1, Diesel 14.5 : 1

So methanol is the most efficient? Which one is the cheapest and easiest to manufacture and store?

For ultimate power yes, but you need to made, store and carry twice the fuel of a petrol engine before you can even start to think about making that power.

Diesel is easy to store and the safest, but engines will be heavier and will only run on diesel.

Non diesel fueled engines can use any of the bellow with a few minor changes to the fuel jetting

Petrol the next easist to store and safer than ethanol as no one will drink it.
But we'll need a oil supply to make any.

Ethanol is harder to store as it will absorb water from the air, and people will drink it.

Methanol is the same as Ethanol only it's poisonous, the antidote is ethanol or a shot of strong vodka.

I recommend that we use a mix of petrol, ethanol and methanol based on availability, with the aim to reserve petrol for the air force

Our currant machine gun is what 12kg with a loaded 60 round drum?
Thats not beyond one man to carry.

If we need a SMG then lets just re chamber it the LMG for 7.62x25mm,
Cut 200mm from the barrel, replace the bipod with a forgrip and call it done.

Ayerp. SMG is prolly a good idea but I'd like to focus on vehicles for now since we're not trenchwarfaring or urban fighting and our land is pretty wide open. Assault rifles would be better and again, via funk's method would be p easy to make.

Well, shove that proposal in as 1.1, then lets think about what we need for vehicles besides an engine. We have a gun being proposed, along with what might be an engine suitable for a tank, but no diesel engines...

I think someone should propose a diesel engine, since those can be fueled on oil, plus they explode less...

Parsely · « **Reply #67 on:** October 14, 2014, 03:12:58 pm »

Diesel might be the best choice for combat vehicles if that's the case, I can only assume that we have access to the resources required to produce that kind of fuel. We definitely want to do our best to power everything with the same kind of fuel.

Aseaheru · « **Reply #68 on:** October 14, 2014, 03:28:06 pm »

Diesels can run on veg oil... We have farms, we can fuel them.
Plus, distilling oil gives more diesel than gas, atleast normally.

Did we ever chose a fuel for the General use engine?
Lets try a Diesel version with a few more cylinders and a bigger displacement.

So truck, anit tank gun and a tank engine?
