Log Book for March 24, 2007
Engineering Report
Jonathan Murphy Reporting
Generator/Electricity:
Wendy: not used
Casper Hobbs Meter: 445.0 hrs (+15.5 hrs since yesterday)
Voltage: NO VALUE SUPPLIED
Frequency: NO VALUE SUPPLIED
Oil Level: 1/2
Oil Pressure: NO VALUE SUPPLIED
Water Drained: no
Notes/Comments: Gas Generator - ran twice Morning - started at about 9am with 3.5 to 4 gallons Evening - started early (16:30) with about 4.5 gallons. I'll have to check it before I go to bed, and top it off if necessary. I had to add oil. It had gone down to about 1/4 full, so I filled it to 5/8 or so and it's currently at 1/2
Xantrex Inverter/Dynasty Batteries:
Time - Voltage (Temp Comp) - Load - Temp - Generator Running
18:30 - 26.6 - 6 - 15 - Yes
Notes/Comments: When trying to look into some of the power systems today, we needed into the DC fuse box. So we tried to cut power to the box by flipping the DC cutoff and unplugging the 12V supply (the generator was running, so we didn't expect to lose AC power). The box was definitely still live. All 24V of it. Does anyone know why this is and how to safely fix it? Also, what's going on with the three batteries in parallel leading into the fusebox? A backup 12V supply?
Fuel Status (as of 16:33):
Diesel: Approximate Reading: 3/4
Propane Tank: Approximate Reading: 45% (450 gallons = 1703.4 L)
Gasoline Quantity Remaining: 21 gallons = 79.5 L (no change since yesterday)
Notes/Comments: Used 3.5 gal morning, 4.5 gal evening for Generator.
Oil Status:
GenSet Quantity: 19 quarts (+8 quarts since yesterday)
ATV Quantity: 8 quarts (+4 quarts since yesterday)
V'ger Quantity: 19 quarts (-5 quarts since yesterday)
Notes/Comments: I have adjusted the oil quantities. There is overlap, since most oil can be used for most things. Instead, I will keep an inventory in this box. 5W-20: 1.5 quarts 10W-40: 3 quarts 20W-50: 11 quarts SAE 30: 4 quarts
Water Status:
Outside Potable Water Tank Level: 250 gallons = 946.4 L
Trailer Potable Water Tank Level: NaN cm from the base
Potable Water Meter Reading: 21820.2 gallons = 82598.2 L (+59.9 gallons since yesterday)
Out to Toilet Meter Reading: 6997.1 gallons = 26486.8 L (+18.9 gallons since yesterday)
In to GreenHab Meter Reading: 7705.4 gallons = 29168.0 L (no change since yesterday)
Dishwasher Runs: 2
Notes/Comments: Using between 40 and 50 gallons per day. At this rate, we'll need a resupply by Wed or Thurs.
GreenHab:
Status: 1. Today I installed the pump for the right two bioball funnels. The only piece of the water processing plant that's missing is the pump from the underground gray water tank to the two reservoirs. 2. The Rule bilge pump (500 GPM) from Aquatic Tank 4 to the Toilet Supply Tank stopped working. It blew a fuse, and we blew another fuse testing it. I think it might have lost its water seal on the electric system, and suffered a short across the water. Haven't done much more testing, because we don't have too many 10A or 5A fuses. Replaced it with a brand new Rule 360 GPM pump. The new pump is plenty powerful, and now we should be drawing less power. 3. Cleaned out the toilet supply tank. There were chunks, even though it's filtered. 4. Cleaned out the filters on the spray-down pumps that now pump into the bioball funnels. They gather gunk rather quickly, and will probably need to be cleaned quite often. Towards the end of our rotation, I'll determine whether these pumps are even appropriate, depending on how often they need cleaning. We might be better off going back to the submerged bilge pumps. Ideally, we need something that can handle chunks of gunk, because otherwise it will just build up in the reservoirs.
Crops Watered: yes
Crop Condition: Growing in all directions.
Transportation:
V'ger Used: no
Oil Checked: no
Tire Status: good
Odometer: 184310 miles (no change since yesterday)
Kawasaki ATV-1 Used: no
Oil Checked: no
Tire Status: good
Kawasaki ATV-2 Used: no
Oil Checked: no
Tire Status: good
Kawasaki ATV-3 Used: no
Oil Checked: no
Tire Status: flat right front tire
Miscellaneous Infrastructure:
Mars Surface Suits: No EVAs today. There was rain in the morning.
Upgrade Work: Emily worked on the One Meter more today. The upstairs display has very finicky buttons and doesn't change channels well. She attempted to take it off the wall to investigate the buttons, but apparently it's bonded to the wall so well that the only way to get it off is to remove the top level of the wall. One temperature sensor is sensing the temperature in engineering. Emily is waiting to hear back on whether the temperature sensor cable can be extended without changing the effectiveness of the sensor. The pulse inputs from the water meters cannot be used until we acquire the box connectors to connect the pulse output cables to the meter. Brand has also been asked about this and how to improvise something for it.
