hexamine is the most expensive fuel you can buy smile

coghlan's 24 fuel tablets of hexamine , 0.2oz per tablet, 0.3lb total at 12,900 BTU/LB is 3870 BTU total. you can buy them at these prices
Code:
3870 BUT   / $18.15 USD =   213  BTU/$ dollar
3870 BUT   / $12.83 USD =   302  BTU/$ dollar
3870 BUT   / $6.33  USD =   611  BTU/$ dollar
                            696  BTU/$ dollar
3870 BTU   / $4.35  USD =   890  BTU/$ dollar 
3870 BTU   / $2.53  USD = 1,530  BTU/$ dollar
                          1,610  BTU/$ dollar

Compare that to dollarstore unscented vaseline 4oz for $1 , its 0.25lb * 19,900BTU/lb , 4970 BTU/$

Compare to Walmarts which lists 6-lb Crisco (24970 Calories) 95,400 BTU / $8.98 = 10,620 BTU/$ dollar

Compare to this past winter 40 lb of premium wood pellets for 342,000 BTU / $4.98 = 68,675 BTU/$ dollar


So for a three day or 30 day in-home earthquake kit, hexamine is too expensive as both fuel and tinder.

Everybody has paper and oil/grease/butter around the house to use as tinder to burn pellets or twigs or logs smile

I would leave the hexamine to Ultralight gram counters smile
