Chain Reaction

Summary

• Hydratation

• Electricity

Equipment and protocol

Still assembly

heat source

distillation flask

distillation head

thermometer

water cooler

receiving flask for the distillate

At the begining :

Twenty minuts later :

Ions’ research

1 ml of urea

silver nitrate

distillate

silver nitrate

chloride ions : positive test chloride ions : positive test

@louisvotier #chainreactiontv Pourquoi avoir réalisé ces tests?

barium chloride

distillate urea

sulfate ions : positive test

ureapotassium oxalate

distillate

calcium ions : negative test

pH test :

pH test - in the distillate (to the left) - in the urea (to the rigth)

Result for the distillate : pH=7 Result for urea : pH=9

The directed freezing :

=

drinkable part

Comment produit-on de l’électricité dans l’espace actuellement ?• Mesure de l’électricité produite avec notre cellule photovoltaïque

Production of electricity :

InterpretationsEnergy produced by the light : 30WEnergy produced : 0,30 WEfficiency : 1%

99% of energy is lost.

-> Most performant cells can convert 20% of the energy.

@Clem54180 #Chainreactiontv Is there another way to produce electricity in space ?

How to convert mecanical energy in electrical energy ?

How to convert mecanical energy in electrical energy ?

InterpretationsEnergy produced by the engine : 5WEnergy produced by the dynamo : 3W

Efficiency : 60%

-> Only 40% of the energy is lost.Best alternators can convert 95% of the energy.

Conclusion

Infinity energy

- Requires light- Low quantity

- Energy all the time- A lot of energy

Requires astronauts’ energy
