Produced by Suminda Thilakasena and presented by science writer Nalaka Gunawardene, this episode features the following items:

• An interview with prolific Lankan inventor M A Prince Chandrasena (of Mawathagama, Kurunegala) who holds 4 Lankan patents with fifth one pending. A refrigerator technician by training, he has developed a compact refrigerator that can remain cold (i.e. retain its low temperature) without mains power supply even for 24 hours. This is ideal for storing vaccines that require an uninterrupted cold chain (most vaccines need to be stored between 3 and 7 degrees C). The “Plus 4-7” refrigerator is particularly helpful to pharmacies and the public health service in a country like Sri Lanka that experiences frequent electricity failures.

• A Japanese innovation: a small gadget that can ‘read’ basic emotions of dogs. Can this make us better understand our best friends?

• Introducing another indigenous technology of Sri Lanka: the ‘Dee-rangaya’ that is locally made and helps keep pests away from farmlands.

• An interview with young inventor D Chathura Madushanka, until recently a student of Pinnawela Central College, Rambukkana, who has invented a multi-function shoe. Fitted to the expanded sole of this shoe is a small dynamo that turns kinetic energy of walking into electrical energy. A battery stores this energy which can help charge a range of electronic devices including mobile phones and iPods. The shoe also comes fitted with a torch light that helps walkers at night. He recently participated in Intel International Science and Engineering Fair (ISEF) in Pittsburgh, USA, in May 2012.
