So - my guess is all the drones, loons and nanosats are up to free calls in Africa and parts of Asia - then transcription and market back.

Sooo - any startup to beat them with free calling service and a sustainable business model is cool and buyable. The costs need to be low.

Use airships for mesh wifi? Key thing is to keep jitter low, people can adapt to up to 500 ms one way lag.

Costs breakdown:

airship - $1200-1500
AP - $150
solar - $50
accu - $50

radius - 9 APs
at 200m each

you are covering 1800m radius, so 1 km2 will be 10 above investment - abt $20k. which is probably 10x less than 3g

Future of education

Use it on the same person - so you get a simple 2d picture of him/her and then just transfer the text data for the points of interest, rather than a video stream


+ deep learning for human microemotions, so that the trainer has real time feedback for the state of students:

+ Maybe use a 2d airport hologram of the trainer with the users
   Would be good to make it foldable and working with any standard projector, or with a pico projector

FOMO, reversed

Putting a price on personal money
- as the world of VCs would have it - make them invest personally
- then value their contributions based on their fear of loss (check thinking fast and slow)
- so the end value of their investment is simple - fear of loss*investment
- maybe * fear of public embarrassment?
