Could we be seeing three things, forms for pilings, pipes for culverts, and pipes and tanks for sewage?
Not that I know anything that goes into building a spaceport.
@NomaddThanks for all the pics. I just have to ask. What's up with the curved wall and barbwire fence?
Quote from: midnightrider3000 on 12/12/2017 06:39 pm@Nomadd Just an artifact of the previous owner. The fence was just to keep the big dogs from eating the little dog.

Ok, I'm trying to get this straight: Is this new solar & battery array for the future pad, Stargate, the control center, or some other building?
Also, what is the unfinished warehouse-like building on the left hand side of the most recent panorama for?
I assume there are no published power numbers for any of the existing pads?I guess the largest loads might be propellant chilling, and deluge pumps, if they do not use gravity towers.
But if the gigafactory has extra capacity because of the Model 3 delays, they could probably get batteries by moving about $140 per kwh between companies. (However Tesla and SpaceX handle that)

According to Jim, the vehicle and payload processing buildings tend to work with the doors open and AC going full blast, and are the largest power consumers, but he might not be familiar with propellant chilling requirements.
Hmmm. This seems backwards to me. Wouldn't it make more sense to re-use the already-filtered air? Seems much easier to maintain clean-room conditions by recirculating and cooling already "clean" air, than to take "dirty" outside air and start all over again. Plus, it would use much less power.I'm sure there's a good reason, but I don't quite get it.

Here's an interesting tidbit.Today, you can buy 18650 cells for around $90 / kWh on amazon.com:https://www.amazon.com/dp/B017YLD83S?m=A2MQH67N57UZ7VThese are advertised as 5300 mAh, but such claims are wildly exaggerated. A typical 18650 cell is only around 2600 mAh, or 2.6 Ah. At 3.7 volts, that’s 9.62 Wh for each cell, or 96.2 Wh for the ten pack. So $8.47 / 96.2 Wh = 8.8 cents/Wh, or $88 per kWh.
