While everyone knows you can’t mix oil with water, it appears the same cannot be said of coffee with fire. This according to the New York Times, which recently reported how an aspiring entrepreneur recently discovered coffee’s unique fire burning qualities when he packed a spent cigar tube with coffee grounds and lit it at his dining room table. When he and his wife saw it burn brilliantly with little or no smoke, he looked into the matter and discovered that coffee grounds have 25 percent more energy capacity, 85 percent less residue and carbon monoxide, and 31 percent less particulate matter than wood. With eco-benefits like these, its little wonder the idea of constructing so-called Java-logs out of coffee grounds is starting to percolate.
