Breaking Base Kinesis: How much element can a kineticist really generate or suppress?

[Ravingdork]

Please tell me if I've got this right.

My 16th-level aquakineticist can generate 3 bulk worth of water at a time using Base Kinesis.

According to the equipment chapter, a full waterskin is enough for one person per day, and is light bulk.

A typical human needs about 3.7 liters of water each day (approx. 1 gallon).

So a full waterskin holds about a gallon of water.

So with my limit of 3 bulk with Base Kinesis, I can make about 30 gallons of water at a time, roughly 15 times that of the create water spell or twice that of a decanter of endless water set on full geyser mode.

Neat.

Did I miss anything?

In what ways can this knowledge be used to our advantage? What might this mean for other elements?

Now, approximately how much air is in a single bulk do you think?

Can an aerokineticist in an airtight chamber quickly siphon all the air out of the room with the Suppress option of Base Kinesis, thereby suffocating anyone else trapped within?

I know Base Kinesis can't deal damage or cause conditions, but suffocation doesn't deal damage, doesn't appear to be a condition, and is a side effect of there being no air, not of Base Kinesis directly. It's no more or less direct then a pyrokineticist who sets a dwelling on fire causing those within to get burned.

In any case, I'm sure suppressing the air would be absolutely useless save for this contrived scenario, as anything but an airtight chamber would just have new air coming in to replenish that which was suppressed.

EDIT: According to THE INTERNET, 1 cubic foot of air weighs about 0.0807 pounds. There are 125 cubic feet in a 5 foot cube, which comes to about 10 pounds. Since bulk is estimated at about 5-10 pounds, it stands to reason that 1 bulk is enough to create a momentary vacuum in 1-2 squares. A high level kineticist (4 bulk) could then theoretically remove as much as 1,000 cubic feet of air at a time (assuming normal sea-level earth-like pressure).

Now, if a kineticist can target only specific elements, such as a geokineticist or metallokineticist moving only the gold ore out of the ground (or the rock round it) or an aerokineticist removing JUST the oxygen from the air, then they could conceivably effect much larger areas/weight worth than if they were forced to target "all of it."

waterskins are probably the worst item to use to make an estimate seeing as they started as a 1 full bulk when loaded and were errataed because how cumbersome were to carry around (so they were changed for gameplay effect not for actual physics effect that you are looking for here).

keep in mind that Bulk also counts how easy is to carry something, not just the mass of said something.

as an easy example, a Small sized character is 3 bulk.

and said character can start from somewhere around 30-35lb, or 3.6-4.2 gallons.

nvertheless, 30gallons seems way more than average 3 bulk of equipment (using another example, if we look at other 3 bulk items we have half-plate, fortress shield, ladder, portable ram, etc).

I'd say, based on existing 3 bulk items, we should be looking at items around 20-50kg, or around 30-50lt of water for 3 bulk of water, or about 5.2-13 gallons of water.

Using 1 L(light bulk) of air (I used 1 lb as that seemed like a decent number to use)
Air has a weight of 0.0807lbs per cubic foot.
So 1 lb of air is 12.39 cubic feet.
Assuming a character breathes 6L of air per minute (average for males) this is 351L of air (12.39 ÷ 0.0353, 1 L = 0.0353 cubic feet), which would last 58 minutes.
All of this for 2 actions.
