Nice Koen!
Would you be willing to share what you use for a nozzle in you tuk tuk? How big is the engine? How far can you go on one fill?

Hi Bill,
I think you missed some of my postings before 
Engine is a 3 cyl Daihatsu S200, 660 CC EFSE.
Nozzle size and still experimenting is 34mm, stainless, with a welded rim
Consumption : 5,3 Kg Charcoal per 100Km
Refill every 10-12 Kg
Modest speed between 60 and 80 Km/hr
The only problem , so far, is the gearing, shifting between 3 and 4 going uphill, would need a 3,1-3,2-and so on.
Coz the rpm drop is to big.
Waiting on the arrival on suitable OBD analyzer and also some more advanced eprom programming stuf for the ecu ( reprogramming is fun untill you break some )

Sneak peak for next weeks trip…
Roundtrip almost 2000 Km
Trying to make impression on the way…
Side stickers, check…
Gasifier logo, check…
Model number … check…
The new front and back panel awaiting approval…

Trip update:
roundtrip 1980 Km
Fuel used:
Bamboo Charcoal: 78 Kgs = Average 3.9 Kg/ 100 km
Mixed in dual fuel ecu programmed injection for Non lean mixture
Bamboo derived alcohol aka Methanol, purity 95%
20 Liters = average 1 liter / 100 Km
water drip for core temperature control:
almost 20 liters = average 1 liter / 100 Km
Having my bike, also running on Methanol, on the back as load plus a lot of stuff.
average payload 300 Kg
The programming was not ideal yet, but i am learning
Did have plenty power for this old engine, will have to replace some valve stem seals and probably piston rings as well… 198000 Km on the counter.
at least, after the scrubbing, it looked so nice…
Pictures of course…

Koen ,
You left out one important element of the trip .
How many lemons were consumed ?

Culd you describe the proces a bit? If l am not mistakeing there are 3 possible ways. Destilation, fermentation and Fischer-Tropsch reaction. Wich one do you use?

Hi Wayne,
A bottle off concentrate lemon juice did the trick…
Each pittstop asking the person at the gas station if they had charcoal… made me buy another bottle…

Hi Kristijan,
I use the destilation and the FT process, one for/with the bamboo vinegar and the FT for the enriched gas, this as a byproduct , combined process gasifier/generator/FTP
Also experimenting with fermentation from the cooking process to obtain/extract the sugar from the bamboo fibers…

Ok so you do all 3
Culd you describe the FTP a bit? l did lots of research on FTP but had limited resaults on a small scale reactor. l had an iron catalist with about 15bar pressure.

Hi Kristijan,
My system is modular and adaptable, but basic follows the attached schema.
I use between 50 and 80 bar, near 300 degree celcius
I have quite a few katalysts to use/test
This next weekend we will sign an MOU with the university so i can’t go in detail about the exact process steps, but as always, the fun part is for those who do instead talk 
Ofcorse l respect confidentiality. I am curious only about one thing. Is or is FTP not economical on a small scale. My tests show it is not, so l pointed my research in a different way. If you will say it is lll trust you enough to get back to to the mad science stuff

Some like it hot inside…
These pictures to show how big the glowing mass is inside the gasifier, pulling at 5 Kwh cooking stove.
Inserting a welding rod thru the nozzle, size of the reactor tube is 5"

Hi Kristijan,
The small scale system can be more efficient if you have way’s to use all heat involved.
Using the higher pressure for your gas also allows a better displacement filling efficiency for the engine, ergo more energy output.
Enhancing the gas used for your engine, mixing it with residu’s from the methanol reactor, also benefits the overall efficiency.
A lot of heat coming from the reactor, approx 3000 joules per cubic meter syngas, to be used wisely…
