Diesel vs gasoline, which engine to choose?

Posted by Krzysztof Lis on August 2, 2010

If you’re at the moment in your life when you’re looking for a new car, and believe you’re going to use it for a while, you should make a wise choice. If you don’t want an electric or hybrid vehicle, you don’t have much to choose from, but only gasoline (spark ignition) or diesel (compression ignition) engines. Which one should you buy?

There is no simple answer to that question. Those engines differ a lot in power/torque and efficiency/MPG, the fuels cost is also different. There are many additional questions you might ask to help you make a decision, e.g. do you want to spend more on the engine that will be more efficient and use cheaper fuel?

So let’s take a look at this question only from one point of view: the ability to use alternative fuels if standard fuels become very expensive or even unobtainable. WAIT! There is more to read… read on »

DIY Biogas Plant

Posted by Krzysztof Lis on July 11, 2010

If you ever wondered how is it possible to make biogas at home, than you just found the right place. I’m going to show you two great books to read if you ever wanted to make biogas.

Biogas production, also known as anaerobic digestion, is a process in which a biodigestible matter (biomass) is transformed by bacteria to biogas. It is done in reactors called biodigesters, which you feed with all the waste biomass (cut grass, waste water — especially blackwater, . The remaining digestate is very nutrient-rich and can be used as a fertilizer. Because of that, I believe that anaerobic digestion is a better way to utilize waste biomass than composting, as the latter only produces fertilizer. Anaerobic digestion produces both fertilizer and biogas.

I posted here two years ago a short video on how to make small amounts of biogas, but today I will show you much better ways to make this fuel.

Anaerobic digestion – article from Wikipedia

Posted by Krzysztof Lis on July 1, 2010

As the Wikipedia is a great source of information on many renewable subjects, I don’t want to write my own article about anaerobic digestion — a process that produces biogas.

Below you will find an exact copy of the Wiki’s article on anaerobic digestion. It’ll be used as a reference in my future articles.

Diesel fuel / heating oil replacement

Posted by Krzysztof Lis on June 4, 2010

Many people want to know, whether it’s possible to replace heating oil with diesel fuel. In case heating oil in your tanks run out, is it possible to use diesel fuel instead?

Or the opposite question: is it possible to pour heating oil into your diesel truck fuel tank?

Let’s find out… WAIT! There is more to read… read on »
