this is looking better 16 posts by 7 different people in the last two days.
let's keep it up.

I agree with Robertson on costs.

MOving on to another topic. Fuel tanks and batteries. I don't know where to
start here so let me spit out a few questions. What kind of space ( ESU, PSU,
CSU) do they take up? I can see them in any of the three areas. Like under
the seat of a car or in the back taking up trunk space. Anyhow until we
decide this I will refer to BVU's.
I was thinking that a fuel tank would take about 10 BVU's per liter. Any
comments? Does the same (10 BVU's per PF) make sense or would 5 be better?

Another concern: how much mass do the tanks account for? In my opinion, the
tanks themselves have a neglagable mass. It's the fuel that has mass. The
amount of fuel is constantly changing. I don't think that we what to
constantly be recalculating velocity and economy, so we should have a constant
mass for fuel. My suggestion would be to use the mass of a half full tank.
Which I believe would be about .4 X the tanks capacity in liters.
Battery mass wouldn't change as fuel was used. Therefor a constant value
would work here. maybe PF's/4?

What do YOU think?
