[Stoves] Poor indoor air quality caused by a stove kills 4 on Mt Everest

[Nikhil Desai]

Michael:

Thank you. In fact, I was visiting the small islands of Vanuatu in part to
advise on a solar home systems project proposal. It was just around then
that I found battery torches with LED lights in the Port Vila market for
about $6-20 and also got a free solar battery charger from the local
wireless phone company (battery-to-battery transfer, so should've been
useful for any battery application).

Solar lanterns had been around for some 20 years, and solar LED lanterns
had been talked about for some ten years. But this was my commercial proof
-- even two rechargeable 1.5 V batteries could do the job. (A Li-ion
battery was better, and LED reduced the size requirement of a CFL. Solar
was not key, battery and electronic lighting were.)

Within a few weeks, I began designing, with the help of David Stein (cc'd
here), what was probably the first "solar LED lanterns" or rather a
"pico-PV battery" (for lighting and phone charging) for any government.

I had then felt "the lighting problem is solved" and that "the wi-fi
revolution will drive small-scale electrification".  And advocated
large-scale nation-wide roll outs in another country or entire regions in
the world.

It all came to nought, except for a small grant for Haiti earthquake
relief.  For complicated reasons.

Which is why I am deeply skeptical of the GACC propaganda that all that has
to be done is publish some international standards and donors would open up
their purses, buy Tier 4 biomass cookstoves by the millions.

I am now betting on PV induction cooking and motorized kitchen appliances.
Maybe solar wood chopping for gasifiers and such.
