Cannabis is an amazing plant. Shame it was illegalized for so long. Has so many uses…even if thc isn’t for us

Dude… I’m pretty sure the economy of the future could be based entirely around renewables, hemp, and thorium reactors…

Just because of how fast the hemp grows… it removes loads of co2 from the atmosphere…

I don’t care about marijuana… I’m talking about hemp.

Marijuana should be legal… but that’s not my battle. At least there are a growing number of places in the world you can do it totally legally and most any other places you can get away with it 99.9% (I only got caught once in 7 years of use)

Hemp though… you can’t even get high off of it… It’s illegality was the product of big business lobbying to protect their operations…

When I first started smoking weed I was big into legalization and activism and one of my arguments was all the companies that wanted to make cannabis illegal paid money to do it because hemp was a big competition for them. The prohibition of hemp is even dumber than the prohibition of recreational and medicinal cannabis.

Yeah… people just don’t get it… they don’t really see the course we are on… they are scared of drugs and diluted by mainstream ideologies…

If they realized the damages using lumber had on the environment…

If they knew anything about energy efficiency and what good insulation does…

I mean hemp is beyond practical in every use its proponents have come up with… clothes, homes, even food… oil and fiber… endless possibilities.

They should figure out how to make diesel fuel out of it


bini shells meet should hempcrete

Oh and hemp biodiesel can be done!

Make hemp biodiesel

How to Make hemp Bio Diesel
Titration method

Safety first: Wear protective clothing and eyewear. This is a serious activity and it not recomended for a “weekend project”. This process is only for reference as to what skilled biodiesel makers would do.

Measure Free Fatty Acid content of your oil: Mix 1 ml oil with 10 ml Isopropyl alcohol = 2 drops phenolthalian solution (available in a hobby shop chemistry set suppliers). Drop-wise add 0.1% lye solution ( 1 gm lye in one liter water ) until the solution stays pink for 10 seconds. (20 drops = 1 ml) Record the milliliters of 0.1% lye solution used.

Methanol You will need 200 ml of methanol per liter of Hemp Seed oil. Methanol may be purchased as Drigas available at most automotive stores, read the label for methanol. Also Methanol is available from racing stores. Avoid hardware store methanol (wood alcohol) as it mat contain excessive water content.

Sodium Methoxide For each liter of hemp seed oil you need one gram of granular solid lye for each ml of 0.1% lye solution used in titration of free fatty acids plus 3.5 grams. Completely dissolve the proper amount of Lye in the methanol (Red Devil Lye can be purchased from the Grocery Store). This combined mixture makes sodium methoxide.

Mixer The type of mixer depends on the size of the batch. An electric drill and paint mixer on an extended shaft works well in a 5 gallon bucket.

Transesterfication: Once the lye catalyst is dissolved completely so that there is no sediment, then the oil may be added to the methanol lye mixture while mixing continuously. At first the mixture becomes thicker, then thinner as the reaction proceeds. Collect samples every 5 minutes with an eye dropper into a test tube or clear container. The Mixture will separate into a light top layer of bio diesel and a darker bottom layer of glycerin, soap and catalyst. Continued mixing 30 – 60 minutes until the yield remains constant. Then stop mixing. Go have lunch. When you come back it will have settled into two distinct layers. You have done it! Let the mixture settle for at least 8 hours. Pour off and save the bio diesel top layer into another container. A clear funnel bottomed container is helpful.

Rinsing: The raw Bio Diesel that you have just produced may have some catalyst, alcohol, and glycerin remaining which could cause engine problems, so for long term engine reliability this raw fuel should be rinsed with water. Gently at first then more vigorously rinse with water until the rinse water is clear and the pH of the rinse water is the same pH as the supply water. Settle, Decant.

Drying: Water in the bio Diesel makes cloudy so it must be carefully heated. At 100 C most of the water coalesces and falls to the bottom. This water must be completely removed from the bottom of the container before heating to higher temperature.


Once all water has been removed then heat the bio diesel to 300 f (150 c) to complete dryness. Cool, filter, and store bio diesel in a well marked dry closed container. 100% HEMP DIESEL FUEL (HEMP OIL METHYL ESTER – HOME FUEL)

This fuel may be mixed in any ratio with petroleum diesel. Dynamometer tests indicate full power output with up to 75% reduction in soot and particles. No engine modification is needed to burn bio diesel fuel.
