The thermal radiation is following the laws of PLANK and STEFAN-BOLTMANN: |
|||||||
Radiate energy R, on display space of 1 squared M (meter), it ’s according to absolute temperature T and this is raising to the fourth power.it ’s according to emissif radiating capacity too e. |
|||||||
R = e. 5,67. 10 puissance -8 .T puissance 4 | |||||||
|
|||||||
- In our situation, with greenhouse effect, (see solar panel) there are lesser transmitted
energy. T in KELVIN degree (in outer space, there are about 3°K), we must know Helium pressure, If we want to know the Helium temperature ( See Helium). At 0°C, it isn ’tn ’ reference himself, it will be possible to find the solar energy, even at the north pole. |

- At 0°C, it isn ’tn ’ reference himself, it will be possible to find the solar energy, even at the north pole. | |||||||
