Things to Think About

• Would this product be useful in your

community?

• How can it be adapted to be more useful?

• Not all projects are complete-- some are

still being developed

• Do you have the capacity to work with a

team of MIT students?

Agriculture

Hand-Held Maize Sheller

Slow

Fast

•Small tool for shelling corn

•Made from a variety of

materials

•Produced where limited

manufacturing capabilities

•Reduces time and energy

•Costs less than $1 to produce

Pedal-Powered Maize Sheller

• Bicycle powered corn sheller

• Shells corn 40 times faster than

by hand

•Other attachments

available

Charcoal from Plant WasteProcess & equipment for an alternative cooking fuel that

reduces deforestation, can generate micro-enterprises

and cost savings, and reduces toxic emissions associated

with raw cooking fuel

Water

Clean Water*

*Note these are examples of clean water technologies being worked on at MIT. More specific applications of technologies are available .

Solar

Disinfection

(SODIS)

• plastic bottles

exposed to solar

radiation for 1-2

days for disinfection

Slow sand/

Biosand

•biological layer

forms at top to

remove pathogens

• layers of sand

get finer and finer

towards bottom

Chlorination

• water is dosed

with chlorine

• treatment must

sit for 30 minutes

Ceramic

Filter

• 90 – 99%

removal of

bacteria

PVC Water Pump*

•Simple tool for

drawing water out

of a well

• Makes it easier to

raise the water

Pull up

*EMAS pump - EMAS is the acronym for Escuela Móvil de Agua y Saneamiento (Mobile School for Water and

Sanitation), in Bolivia, whose director, Wolfgang Eloy Buchner, developed this pump in the 1990's.

EC-Kit – Simple, Off-grid, Coliform Field Test Kit

2 separate tests for E.coli and total coliform

Complete set of the components of the EC-Kit, which get packed in

a cooler bag (not shown)

Tamale, Ghana, June 2009 – a MIT appropriate

technology invention!

Mobile Phone

Mobile Farming Info• Uses mobile phone

technology to connect

rural farmers to each

other, to the market,

and to large

companies

• Get current market

prices and exchange

farming tips easily

Other

Pedal-Powered

Washing Machine

• Decreases time spent

washing clothes

• Uses common bicycle parts

and a large drum

• figure-eight drive allows users

to switch between the two gears

by changing the direction of their

pedaling, with both directions

resulting in forward propulsion

• can freewheel in the forwards

direction, though no backwards

movement is allowed.

• the steering column can be

rotated 180 degrees, allowing

one to ambulate and freewheel

in reverse

Two-speed tricycle/figure-eight drive for the

hand powered tricycle
