It is not just the average consumer who is interested in these products but the military is also extremely interested in using such sugar-powered batteries. The portability of such devices would be appropriate for the extreme mobility required in the battlefield. It would also be suitable in emergency situations when access to electricity and other vital gasoline supply lines are cut off. Using any kind of sugar source available in the vicinity would be enough to charge up the batteries. (Fuel cell batteries that run on sugar) The energy needs of the U.S. Armed Forces are extremely high and the Department of Defense requires a constant supply of fuel for its military jets. Therefore, as per the instructions of the U.S. Congress, DOD and DARPA have also evinced interest in alternative fuel sources like ethanol derived from sugar. (Bio-fuels for the U.S. Military) Conclusion

Rising crude oil prices, environmental concerns, and gradual depletion of non-renewable energy sources have fueled interest in the research and development of alternative fuels which can prove to be clean, efficient, less energy-intensive, sourced from renewable materials and environmentally friendly. Brazil has already paved the way for a shift away from a gasoline-dependent fuel to a more sugar-derived ethanol dependent fuel. However, ethanol has its share of limitations and scientists are actively working on producing other kinds of energy-efficient fuel from sugar derived from biomass. Various degrees of success have been achieved by several teams working towards this goal.

Some researchers have targeted living cells like bacteria who consume sugar, producing enormous amounts of hydrogen that can be used to power hydrogen fuel cell-based vehicles whereas others are working on converting...

These kinds of innovations may pave the way for an entirely new kind of fuel for the future and may reduce dependence on a few oil-producing countries of the world. This might mean more independence and economic progress for the Third World countries as well. On the whole, progress in the field of developing new fuels from sugars and other biomass derivatives has been steady and the day might not be far off when instead of queuing up at the petrol pumps, consumers may be seen queuing up at grocery stores to fill up their vehicles.
