Why can’t they look like these?

Small-Scale Complete-Cycle Biodiesel Pilot Plant: Technology Transfer to Communities in Celebration of
His Majesty King Bhumibol’s 60-Year Anniversary of Accession to the Throne

What did we learn from our mistakes?• Assume nothing • Just ask• Find out their true happiness• Apply a holistic approach
(the whole value chain)
![Page 14: Human-centred HCDI Seminar: Approach in Scientific Research](https://reader036.vdocuments.mx/reader036/viewer/2022081414/54bb190a4a7959ec718b4575/html5/thumbnails/14.jpg)
What do they want?• Independence • Self-sufficiency

Holistic ApproachA business case for a community-based
biodiesel production

Did we really listen?
![Page 17: Human-centred HCDI Seminar: Approach in Scientific Research](https://reader036.vdocuments.mx/reader036/viewer/2022081414/54bb190a4a7959ec718b4575/html5/thumbnails/17.jpg)
Biodiesel: What is it?Biodiesel is defined as a diesel-equivalent, processed fuel obtained from biological sources. In this case, it refers to alkyl esters made from the transesterification process of straight vegetable oils (SVO) or animal fats.
![Page 18: Human-centred HCDI Seminar: Approach in Scientific Research](https://reader036.vdocuments.mx/reader036/viewer/2022081414/54bb190a4a7959ec718b4575/html5/thumbnails/18.jpg)
Actually, the process is simple.No equipment needed.
![Page 19: Human-centred HCDI Seminar: Approach in Scientific Research](https://reader036.vdocuments.mx/reader036/viewer/2022081414/54bb190a4a7959ec718b4575/html5/thumbnails/19.jpg)
But the specification is strict!!!
![Page 20: Human-centred HCDI Seminar: Approach in Scientific Research](https://reader036.vdocuments.mx/reader036/viewer/2022081414/54bb190a4a7959ec718b4575/html5/thumbnails/20.jpg)
Polypropylene (PP) Density = 0.855 g/cm3
Low-density Polyethylene (LDPE) = 0.910 g/cm3
In fact, we should produce test kits, which are fool-proof, affordable and reliable. If we can give them away for free,
that will be the ultimate situation.
The density of a material is defined as its mass per unit volume
Density = Mass / Volume
Bio-diesel Density = ~ 0.88 g/cm³
Can you design a fool-proof density test kit?

In order to keep the cost down while maintaining the quality, we tried to use standard parts for everything
![Page 22: Human-centred HCDI Seminar: Approach in Scientific Research](https://reader036.vdocuments.mx/reader036/viewer/2022081414/54bb190a4a7959ec718b4575/html5/thumbnails/22.jpg)
Let’s come back to General Hospital Equipment

Broadest Design Brief Ever??? • Design any hospital equipment for the Thai public healthcare• Justify impacts on the society (Niche market is unacceptable) • Leverage knowledge, expertises, technologies cultivated at MTEC• Able to transfer knowledge to the Thai industries

Users knew what they want, but they’re too specific
