La sphère de dyson
rentrons dans le vif du sujet
quece que c'est la sphèere de dyson?
Lorem ipsum dolor sit amet
1- La naissance de cette idée
+ INFO
Le nuage de Dyson
L’essaim de Dyson
La sphère complète
un ensemble encore plus dispersé de structures qui collectent l’énergie.
un grand nombre de satellites en orbite qui captent progressivement l’énergie de l’étoile.
une structure solide entourant l’étoile. Mais ce modèle pose de nombreux problèmes
moment de theorie
combien d'energie pourront ont obtenir en utilisant des panneau solaire tapissant la sphere du soleil ??
3.8×10.26 watts. PAR SECONDE!
Comparison
ENERGIE ÉMISE PAR LE SOLEIL PAR SECONDE
Consommation Mondiale :
environ 6x10.20 Joules par AN
3.8×10.26 Watts
+ INFO
3.8×10.26J/6X10.19 J= 6,33x10^6
Comparison
ENERGIE ÉMISE PAR LE SOLEIL PAR AN
Consommation Mondiale :
environ 6x10.20 Joules par AN
1.2x10.34J par AN
+ INFO
1.2×10.34 joules par AN
DONC: 1.2x10.34 J/6x10.20J= 2x10.13
moment de theorie
C'est bien de savoir la quantité d'energie qu'on peut recevoir mais alors quel sera sa masse si on etablit la sphere de dyson?
1- CALCUL DE LA SURFACE DE LA SPHÉRE ( donnée en cours aussi)
S uface= 4 x π x(1.5 × 10^11)^2 Surface = 4 x π x (2.25 × 10^22) Surface ≈ 4 x3.1416 x 2.25 × 10^22 Surface ≈ 2.83 × 10^23 m²
2- CALCUL DU VOLUME DES PANNEAUX SOLAIRES
Volume panneaux = S × épaisseur Volume panneaux = 2.83 × 10^23 m² × 0.1 m Volume panneaux = 2.83 × 10^22 m³
2- CALCUL DE LA MASSE DES PANNEAUX SOLAIRES
M = Volume panneaux × densité M = 2.83 × 10^22 m³ × 2,700 kg/m³ M ≈ 7.64 × 10^25 kg
Comparison
Masse de la sphere de Dyson
Masse de laTerre
6x10^24 kg
M ≈ 7.64 × 10^25 kg
+ INFO
et si on veut savoir précisement combien de fois la shpere de dyson est plus lourde de la Terre :
Masse de sphere/ Masse de la Terre= 7.6x10^25/6x10^24=12.7
faisabilité du projet:
- Problèmes techniques et matériels -Problème de conflits -SOLUTION ALTERNATIVES
