The 14% is about the floor space and that revised number (more floors etc.) has been known for months:
1.8 to 1.9 million sq ft out of a total of 13.6 million sq ft of operational space. 14%.

Elon Musk Powers Up: Inside Tesla's $5 Billion Gigafactory
Maybe they revised that number upwards again in the meantime? Plans are cheap, execution is not.
In the end it's all about actual money invested. Battery manufacturing for current cells is well understood, equipment has its price. If you believe Tesla (and Panasonic) can magically produce 50, 100 or 150 GWh worth of cells and batteries a year soon without first investing billions more into the factory, then do so.
PS: This is similar to Musk talking about the Fremont factory 'potentially' producing up to 1 million (compare that number to what NUMMI produced on the site in its heydays, about half that output!) cars a year. Also note how Musk and other Tesla execs never talk in details about the additional cap-ex needed to get there one day...
My point is that the 14% floor space is no longer a relevant reference to the initial planned capacity of 50 GWh. You have more than once implied here and on various other forums that 14% floor space is not enough room for the cell & pack capacity required for the early Model-3 production. As of yesterday it is confirmed that that 14% floorspace (as they have already
today) could very well be enough not for 14% but for 42% of the old plan of 50 GWh = 21 GWh. That 21 GWh alone would be enough capacity for 300.000 cars with even 70 kWh. And that is additional capacity to the currently available proven cell capacity available for Tesla of at least 75k / 100k cars a year. So even assuming Tesla will not extent the floorspace between now and 2018, there is not issue.
Thus my respectful request to not use this 14% or floor space argument again, not here, not on other websites, as you now know this is not a an honest statement.
You have often spread doubt on the investment already made into the GigaFactory...
I am not sure you followed the whole websession yesterday, but I now inform you that Elon Musk stated at the shareholders meeting that already
today a total of 2B have been invested by Tesla and partners in the GigaFactory. That is 40% of that 5B investment already between site selection announcement in September 2014 and May 2016. 2B of the total 5B investment promised to be made until 2020. So no magic required, but lots of hard work and real money as both have indeed already been invested by Tesla and partners.
So next time you make statements here or on other forums where you create doubt by implying otherwise, be honest and explicitly accuse Tesla of lying in the shareholder meeting, so we can call you out on that. IMHO you should not make such statement without very strong proof.

EDIT / P.S. just to be one step ahead before tftf would now make up a new complaint that 2B was already spend on just 14%.. How to finance ???
Well 2B equals 40% of 5B.. Just like 21 GWh equals (about) 40% of 50 GWh. Coincidence ?
And I actually claim that every next 10 GWh capacity will cost much, much less than 1B each as many significant on-time costs are already paid for now. (land, infrastructure etc, etc).
