Hello Richard,

Below are the questions you had filled out by Tom Daily, who is
running the Timor project.

The timeframe he indicates is one of two dates we would be giving the
laptops to kids in Timor, the other would be January 2010.  In the
mean time, the engineering guys who are involved with the project
would be very interested in doing some testing of the MBC.

Also to note is the power source; Tom says we will have AC, but it is
intermittent, and some of the engineers are looking into a wind based
setup.  I felt this was worth mentioning.

Cheers,

Joel

We are planning a pilot of 45-55 over 2 schools in East Timor

Titi lari East Timor and Hera East Timor.

AC

Initially we have power from 6AM until midnight available so we can
charge the battery laptop and charge a spare as well to increase the
daytime availability of the laptop.

Yes this would be the plan

We could use one in Sept/Oct if we can source the 55 laptops by then.

Short term 1 for AC only.
Longer term we probably could use AC and DC chargers, but this is
dependent on the pilot success (which I anticipate being successful if
we can source enough laptops and this should eventually drive govt
interest and then the number larger but I can't yet quantify and it
would be unrealistic at this stage to try)

Absolutely.
We are keen to document our pilot and make it replicable.
