"Good pick up Evan - my multitasking skills could do with some improvement! Here's an update "

"This is an interesting thread. In our three trials we found quite a bit of variability within countries but similar averages across the three countries. Our Tanzanian trial was 1,000 lights over 3 months, whilst the Bali and Philippines trials were…"

"All of our studies were undertaken in rural villages. I agree with Kat in that a simple rural/urban split would provide quite a bit of insight. It is pretty safe to say incomes are significantly higher in the urban areas so the proportion of income…"

"Thanks Daniel. There certainly seem to be some pretty hard physical limits on the technology. For anything to be really useful I would think 15 Lumens for 3 hours would be the lower bound. It sounds like to achieve this outcome it could only be sold…"

"Hi Yotem, Please keep us updated on how this goes. I'm really curious to see if anyone contributes because I'm not sure what the motivation is to do so, i.e. if an individual has a game changing design innovation what is the benefit of…"

"Thanks for the summary. I'd love to hear more (as i imagine would other non-attendees) if anyone has something to share. Any idea where the 10% of products that are not manufactured in China are made? Also, how are they measuring improvements…"

"Hi Yotam, Yes you can get me on LinkedIn. I will send you an email with the address details etc.. Thanks, and again, well done!"

"Interesting and innovative idea Yotam. Good luck with it. Anything that increases the chances of customer feed-back in such remote areas should be extremely welcome by quality manufacturers. We would certainly be interested in giving it a shot."

"We are currently only beginning to look into this issue in depth so forgive me if I'm a little inaccurate. From an African perspective it looks like there is a company in South Africa that does battery recycling, however it looks like the…"
