SUMMARY

The discussion centers on the energy storage capabilities of borax, clarifying that borax is a compound, not an element, and does not possess the high energy density claimed by some. It highlights sodium borohydride as a potential hydrogen source for fuel cells, which may be the source of confusion. Additionally, while boron is utilized in nuclear reactors as a neutron absorber, there is no credible evidence supporting the claim that borax can provide energy equivalent to 100 tons of coal. The assertion that a car could travel 19,000 km on 1 kg of borax is unfounded.

PREREQUISITES
  • Understanding of chemical compounds and elements, specifically boron and borax.
  • Knowledge of energy density concepts in fuels.
  • Familiarity with sodium borohydride and its applications in fuel cells.
  • Basic principles of nuclear physics, particularly the role of boron in reactors.
NEXT STEPS
  • Research the properties and applications of sodium borohydride in fuel cells.
  • Explore the energy density of various fuels, including coal and hydrogen sources.
  • Investigate the use of boron in nuclear reactor designs and its function as a neutron absorber.
  • Examine the historical context and technology behind BORAX reactors.
USEFUL FOR

Scientists, energy researchers, and anyone interested in the chemical properties of boron and its applications in energy production and nuclear technology.

One of my friends is insisting that a car can go 19000km with only 1kg of http://en.wikipedia.org/wiki/Borax" , and only one tea-spoon of borax can extract as much energy 100 tons of coal does.

Is that true?
Does borax contain this much of chemical energy?

There has been some chatter about sodium borohydride as a hydrogen source for fuel cells. That's about the closest thing I can think of that your friend may be referring to.
 
Borax is not an element, it is a compound. Boron is an element.

When speaking about chemical energy there are no materials with so high energy density.

I don't remember details, some claim boron can be used as fuel in nuclear devices (it is used in all existing reactor designs as a neutron absorber, but that's a different thing). No idea if there is serious physics or crackpottery behind.

Then, there were BORAX reactors http://en.wikipedia.org/wiki/BORAX-I
