Goals of the Big Green

• Around Chintsa there are 3 classrooms with around a dozen of computers to teach IT to children / adults where there is no access to computer / internet

• There are other places around to teach IT but there is no classroom and many people cannot come to the IT classroom

• The Big Green will be a remote mobile computer school• The Big Green should be autonomous regarding

electricity with solar panel to work 5 hours a day• Initial donations come from Hungryman to be able to

start the project, many thanks to them

Storage (1/2)• Space for :

– Wireless switch (wi-fi)– Router (3G/GPRS or Satellite)– Printer– Power management console for solar– Possible storage space for laptops during

transit

1 case for 4 laptops

Removable to take off the Big Green when parked Router, printer, wifi need to be locked and removable

6

Storage (2/2)

• If the laptops could be stored in an alternative place during transit, the central area could remain open; creating a more airy feel during teaching.

• The space within the two side areas should be sufficient for other needs.

7

Opening roof (1/3)• Current roof height is 165cm• More height is required to be able to teach for 5hrs• Solution to move the whole roof seems to be complicate• Bars to be removed = structural risk, but already done on

Big Green brother (same truck with an opening roof)• Protection to install as there are risks to knock your head• Need water-tightness

Battery

• Good space to install could be below the floor on the right side (opposite side to the engine battery)

11

Solar panel• Possible with financial support• Study structure requried• Heavy : 170 kg• Rotate on the roof to be more efficient (~30°)• Take the whole length of the Big Green (no water tank)• Can be fixed with 2 pistons

12

Remarks

• It would be possible to get more laptops

outside of the Big Green

(later phase)• Fixation on the back to avoid

movement / balance when

moving inside the Big Green
