| Riccardo: consider to replace batteries with fuel cells? Instead of bringing batteries, you need to bring the water and the salts. At the spot, you would mix in the salts to make the acidic and basic solutions. With a large tank could last a year. Could be cheaper in the long run. There are different models. Comes as a small box with tubes to tanks from which they suck the solutions. Produce salty water and hydrogen which is burned to produce electricity. Few gallon tank, you could run for 6 month. Should be feasible in the mine, but is it useful (in terms of costs and portability) and do we trust the new technology. Two times 10 l gives 6000 W-hours, $3500 per station, cheap to extend duration. | Riccardo: consider to replace batteries with fuel cells?

| Vuk: should look at it more, maybe we'll try to get one unit to play with in the lab. This is more expensive than what we are currently thinking for batteries, but we may have to increase the power requirements to support the GPS receivers. In that case, the fuel cell option may become more cost effective. | Vuk: should look at it more, maybe we'll try to get one unit to play with in the lab.

| Vuk: will speak with SURF next week. Propose to ask them to start preparing the stations (rock-bolting etc), excluding 800-1, 800-2, 2000-1, and 1700-2. Over the next 2-3 months we should converge on the GPS fiber technology, so that we can start stringing fiber cables etc. | Vuk: will speak with SURF next week.

| Tanner: working on the software, trying to access the bailer and retrieve the data. Gary sent us the Antelope package, a software package that should help us with operation at Homestake, retrieving the data. At the moment struggling to install it. Upgraded to 64-bit OS, but now failing to find the relevant pearl library. Is ubunty system ok? Currently at the second floor, but have poor GPS access. Will try to move to the top floor to get a better access. | Tanner: working on the software, trying to access the bailer and retrieve the data.
