Still in need of practical experience. My dad threw out an old lawn mower i was going to experiment on, but i'll find something, just need to find the time and effort. The trimmer for one, adjustable carb and all. Changing or drilling jets is easy, it should work that way, make fine adjustments

Methyl ethyl ketone is at least the solvent of choice in the aviation industry. The general rule of thumb in those circles being that everything's more toxic than in the automotive department: leaded AvGas, high sulfur jet fuel(not to mention the additives they throw in), hydraulic fluid which

I'm used to heating with wood anyways, so a wood gasifier is the first thing that comes to mind. An old car engine with nothing to lose and the capacity to have it's output at peak torque (peak efficiency) halved would be just about the thing for any DIY:er. In box with noise insulation and 3

Walking around at the snowmobile expo in Jyväskylä, Finland yesterday, a Lynx Yeti 1300 caught my eye. Great work sled, yes, but what I really was looking at were the 2 scuba tank type bottles peeking out from under the seat. This wasn't NOS, I was sure. Later on I had the privilidge to talk

I've understood that it's some rubber or plastic parts that start to degrade, not the metals. I'm thinking it's just a new chip or reprogramming the ECU injection/ignition curves and an ethanol/gas ratio sensor, since you can tank either (hence the term flex-fuel). They probably slap in ethanol

Re: [Biofuel] Dewatering with vacuum.

2006-01-18 Thread Arttu Aula
You're talking about 2 different things. Talking about so-and-so-much vacuum is sort of misleading. Your 30Hg of vacuum means 0Hg (0 mmHg, 0 mbar, 0 psi) absolute pressure; the vapor pressure points were absolute pressure. Absolute pressure is measured according to how high of a column of mercury

If I undestand charle's spreader idea right, would an inclined base on the trailer work to get the compost to the spreader? Then adjust the pulley ratio to control rate. Could it be that simple? If the compost doesn't flow down freely, especially when there's little of it, a simple conveyer belt

[Biofuel] Efficiency and expanded possibilities.

Fuel preheaters and other forms of gasoline vaporization were used extensively in the beginning of the 19th century, especially in tractors. This greatly increases a spark ignition engines efficiency, as only the vaporized fuel burns. Conventional engines (even your brand new EFI) vaporize

Apparently ethanol has 68% of the energy content of gasoline by volume (8.9x10^7 J/gal vs. 1.3x10^8 J/gal). Therefore gasoline has 146% of the energy content of ethanol by volume. This translates to 1 liter of gasoline = 1.46 liters of ethanol. 46% more ethanol to equal a volume of
