Simi Stove Cooking Gel is Ethanol based. When compared to solid fuels, Ethanol is by far the cleanest burning. It does not produce toxic fumes, soot or smoke and produces zero greenhouse emissions.

For ease of transport and safety in use, we make our fuel

into a gel.  This requires adding a thickening agent and

water to the Ethanol. This can reduce the heating level of

Ethanol, but by maintaining a high percentage of Ethanol

to water (85%) and by designing the stove to specifically

burn Ethanol, we overcome this problem.

Our patented stove design has enabled us to reach twice 

the average efficiency of all clean cook stoves tested; 

67.3% compared to an industry average of 36%. 

It can boil a litre of water in under 10 minutes making 

Simi Stove, when used with our Simi Stove Cooking Gel, the

only high-volume Ethanol cook stove on the market today.



Ethanol is Alcohol and could conceivably be ingested. To counter this, we add a substance called Bitrex.

It is one of the most bitter substances known to man and will deter anyone from attempting to drink our fuel.

One other additive we use is Citronella which helps keep insects at bay during the cooking process.

The addition of these two substances, Bitrex and Citronella, does not alter the effectiveness of the fuel.

​The Advantages of Simi Stove Cooking Gel

  • Consists of renewable primary products

  • Very clean combustion with negligible emissions and no soot

  • Can safely be used indoors; eliminates Household Air Pollution (HAP)

  • Heat available instantly after ignition

  • Can extinguish and relight fuel during cooking

  • Provides a safe alternative to LPG when not pressurised

  • Can be produced from a variety of feed-stocks, when grown from sustainably harvested feed-stocks, and is a renewable fuel.

  • Intrinsically cheap

  • The development of alternative feed-stocks, more applicable to local conditions, has the potential to improve yields, farmer income and food security
