Just one big heat sink in Summer and tomorrows slums. There is a good book called "Winning back the Cities" ihough it's more geared (sic) towards a local cycling future but looks at and has some good answers towards more livable cities with community living amongst green corridors and properly designed public transport hubs which actually connect with each other.

Again another good reason to use Jatropha.
I remember going through all the requirements to apply for import of the seed here for a personally crop back before this video was posted in 2010 but good ol Govco computer said NO. And here we are still scratching out nuts (no pun)

The only thing that could make those heat islands better is siting meteorological stations in them. Don't laugh, it's what they've done.

I just came back from Singapore, premium petrol is currently $3.80 per litre at the moment. Count ourselves somewhat lucky I guess.

Crops like the Jatropha, great idea, we are going to have to do this stuff ourselves, looking to authorities for direction will be a long, long stare...

I think a much better way of Bio farming would be Algae. It started the oil in the 1st place!
1kg of Algae consumes 1.8kg C02 per day 1 acre Maple Forrest consumes 2.2kg per day. Fill some old mines with favourable conditions and your favourite algae and away you go https://www.youtube.com/watch?v=3ZKbyXCrTG8 |

Yes true, it's mentioned as the crop beyond any plant based oil sources. US researched it a lot in 2000s... How to get the CO2 into the algae quickly at scale? Once all the land next to industry (wot industry?) is taken

BTW. I think that Jatropha is a noxious weed in some states, so I can't see that being popular.

Rokwiz, even though you run your trucks on WVO, have you tried making biodiesel out of it and running that? You'd need methanol and sodium hydroxide, then get rid of the glycerine out of it, if you wanted to make soap from the leftover glycerine you'd probably need to boil the methanol out of it first, not sure if there's a market for methanol soap
It wouldn't have the viscosity issues that WVO has, gel point would depend on what the WVO was. Would be interesting to get your trucks over to an emissions lab, if we could go back in time a decade we could have done it for free at my auto TAFE before they fired the only teacher certified to use their emissions lab Now its privatised and you pay like $1500-$2250 for a 5 minute test.

Hurdles Franco, there's your answer as to why I run used veggie oil. Why would anyone put themselves through wasting their time with officialdom.

https://www.sciencedirect.com/scienc...76610215027964 In conclusion......The results of this study show that 1 biodiesel has the potential to reduce emissions from 2-stroke Diesel engine 2 It can be used in this engine without modification Have run it to B50 with no harmful effects along with the 903 V8 Cummins. Cummins does like to smoke more when cold but that's a trait of all VT903's.

Canola derived biodiesel doesn't gel under minus 20 degrees C WVO (that roKWiz uses in his trucks) and biodiesel are two different fuels, basically biodiesel is a process later, its more refined, you can make biodiesel from WVO with some processing using methanol and sodium hydroxide/potassium hydroxide depending on how keen you are playing science experiments at home. Or in his case you can just get waste vegetable oil, filter the crap out of it and either run it straight or mix it with normal diesel in varying degrees depending on the temperature and how keen your injection pump and injectors are on higher viscosity liquids. Older diesels no dramas, all the oldskool indirect injection stuff would tolerate it, but anything modern like common rail with their injectors with multiple fine holes creating a very specific spray pattern and massive fuel pressures, one imagines it wouldn't survive very long being fed WVO.

There's also people running separate fuel tanks for WVO, separate fuel lines, heat exchangers et al, car starts on regular diesel first, once engine is up to running temperature they switch over to WVO now the heat exchanger is warm and has warmed up the WVO tank/fuel lines.
I saw someone doing this with a glow plug to warm up the WVO in the lines, not a bad method doesn't rely on coolant traveling around the car outside of the cooling circuit. Given current prices, surely commercial B100 that can be used in modern diesels would be worth considering firing up again? Last edited by Franco Cozzo; 20-06-2022 at 11:52 PM. |

As stated if you read back and going along with what Franco posted. In Summer my trucks run B90 that is 90% used super finely screened cooking oil with 10% diesel added. The diesel will always stop the problem of gelling and algae on an occasional cold summer morning start. Before the middle of Winter I'll blend a mix of 50% used cooking oil, 10% Kerosene and 40% diesel. (sometimes the blend is reversed and 40% used oil and 50% diesel) Kerosene is added to fuel around the alps areas here anyway (farming winter mix) in Winter. Mid seasons the blend will change to B60 60/40 veggie oil /diesel mix. All the veggie oil I have used so far is from 2 local cafe's, pick it up in 20ltrs drums and is screened filtered several times before blending at the Summer base figure of B90, then stored in 3 separate diesel tanks. I found all along the Hume and Pacific Hwy corridors, several small town communities dabbling in the voodoo art of Biodiesel where it could be purchased from them to allow travel all up and down the Eastcoast. The reason I always use some measure of diesel in the blend and have never used straight veggie oil is I'm not keen on needing fuel heating modifications to the fuel systems in them. (apart from replacing all flexible rubber hoses and secondary added filters) Just adding in here its used in my 2 cylinder Nanni yacht engine as well as a 8Kva genset and heating our little offgrid house.

Reasonably successful plant here only recently closed due to no ongoing support from Govco. The diesel engine will take a while to become cleaned from soots and will need plenty of filter changes when freshly converted. The power will be lower until the internals start to clean themselves. The power always returns stronger.

SVO - straight vegetable oil They can be used interchangeably I guess but the way I look at it WVO nails it down to used cooking oil. Check out this setup, this is better than the water/fuel heat exchanger idea I reckon Basically a fuel sump made out of cast plumbing fittings with a temperature controlled glow plug to heat up WVO on its way to the engine, would cut down your switch over time if running 100% WVO. Because of the viscosity of WVO, a diesel lift pump like a Walbro FRB51 (or FRB21 if 24V) would work mint I reckon. https://www.walbro.com/fr-series-fue...ing-fuel-pump/ https://www.walbro.com/fr-series-fue...ing-fuel-pump/ These series of lift pumps are designed for longevity and ****ty fuel, and are available locally, perfect. I had issues on ambulances with the rear cabin heater doing SFA in VIC winter, what happened was by the time the coolant went from the engine, to the heater in the rear of the van it had already lost a lot of its heat on the way there through the hoses, so it was basically blowing cold air, rendered it absolutely useless at idle, it sort of worked at higher engine speeds but it wasn't much chop. It was solved by ****ing off the heater core for a diesel heater in the back, now it works mint year round and instantly. I reckon you'd have the same issue with relying on engine coolant to heat fuel lines or through a heat exchanger setup at the tank end, maybe not so much if it was in the engine bay though with a shorter run but warming the fuel lines like I've seen other setups do wouldn't be ideal. The glow plug idea with the controller is mint, you don't need to plumb coolant lines around the car or increase the volume of the cooling system either, nor wait for the coolant to come up to temperature to warm everything up before switching to WVO - its a lot easier to run wires to a glow plug. |

I was subscribed to Renew magazine for years which featured great articles on all things bio. Seemed at the time the obvious way this country would go but we have an agenda. Quarter filled the little truck diesel tank today in Benalla @ $2.12 pl which was added to the all ready three quarter tank of the home brewed B90 added yesterday. Started 2nd go this morning so not as cold.
