that I'm working on,
to make a huge impact around the world.

in children under five.
from indoor cooking fires --
caused by this.

cleaner burning cooking fuels?
to over two million deaths every year?
about the wonders of carbon nanotubes,
about the wonders of carbon macro-tubes,

of environmental problems
throughout the nation.
there was severe flooding
to stabilize the soil.
and the flooding happens.
why there are so few trees is this:
and they make charcoal in order to do it.

there might be a better way

is we wanted to make a fuel
readily available on the local level.
from the sugarcane
so they don't feed it to the animals.
until eventually they burn it.
we wanted to find a way
and turn it into a fuel
that people could easily cook with,
to develop a process.
and then you take a very simple kiln
a waste fifty five-gallon oil drum.
that goes into the kiln,
with this carbonized material here.

if someone has a question --
that you've worked on.
things we're working on
water quality testing,
their own water systems,
know when they treat them, etc.
is looking at solar water disinfection
to be able to do that.
preventing this stuff getting from scale?
or venture capitalists,
what you've got and get it to scale?
of people moving it forward.
which is very fragmented
that you use in the United States
I do what I can with the students.
go out into the field
and move it forward.
with a long time frame,
something done in a year or two years;
five or 10 years ahead.
we can move forward.

Why you should listen
Mechanical engineer Amy Smith's approach to problem-solving in developing nations is refreshingly common-sense: Invent cheap, low-tech devices that use local resources, so communities can reproduce her efforts and ultimately help themselves. Smith, working with her students at MIT's D-Lab, has come up with several useful tools, including an incubator that stays warm without electricity, a simple grain mill, and a tool that converts farm waste into cleaner-burning charcoal.
The inventions have earned Smith three prestigious prizes: the B.F. Goodrich Collegiate Inventors Award, the MIT-Lemelson Prize, and a MacArthur "genius" grant. Her course, "Design for Developing Countries," is a pioneer in bringing humanitarian design into the curriculum of major institutions. Going forward, the former Peace Corps volunteer strives to do much more, bringing her inventiveness and boundless energy to bear on some of the world's most persistent problems.
