Map reference the city is near to tokyo(the capital) probably Nagoya .
And the temperature of Tenjian ice is Absolute Zero or below that.
So using Nagoya as reference, we also need to know how much energy is needed to freeze the city. First we need to know the size of the city, and in internet are the radius, area, etc.
So the formula of specific Heat is complicate to me, but Omnicalculator have that options, so to makes things easy. Well, firstly we need to know the volume of air in the city and the formula is V=length*width*height.
Knowing that the radius of Nagoya city is 50km, the diameter is like 100km, so in lengh and width the value is 100000m and in height the most tall building in Nagoya the tallest building is the Midland Square of 247 meters and 42 stories, but in Azure Striker Gunvolt World, in the cities they have buildings of 63 or 62 stories who is like 278 meters. So using the formula we have V=100000m*100000m*247m=2.47e12m^3 And to know the mass is only multiply this with air weight who is like 1.2kg/m^3 so 2.47e12*1.2=2.964e12kg So the energy of the air part is:
878873424000000000 joules or 210 megatons of tnt The second part is the concrete, is the same proceses, but in this case i need to use the weight of the concrete this one is 2362kg/m3.
Using the same formula we have V=100000m*100000m*247m=2.47e12m^3*2362kg/m3=5.83414e15kg
The energy is:
1565883176000000000000 joules or 374 gigatons of tnt
The final result is multiplying the concrete and air results: 1565883176000000000000+878873424000000000=1,566,762,049,424,000,000,000 joules or 374 gigatons of tnt
In the beginning of the game Kirin clarify the fact that after GV turned into a Primordial Dragon and get his power sealed with thousand glaives Sumeragi uses him to supply energy to all the country during decades.
And in Abandoned Fabric stage, Kirin also said that GV energy eradicate the uses of fossils combustibles. So Gunvolt is supplying energy to all the country on his own.
So firstly we need to know how much energy a country like Japan consume and is like 903.70 billion kWh per year.
Now with that, i gonna calculate how many Energy Gunvolt generate in decades(i gonna use a value of 30 years). So Japan consume 903.70 billion kWh per tear and the formula to know the values is kW*hours*years.
So the calculate is 903700000000kw*262800h*30y=8.66847114e19kwh.
Know the to convert kwh to joules is simply the equivalence is 1 kWh = 3.6e+6 Joules, so 8.66847114e19*3.6e+6=3.12064961e26 joules or 74 petatons who is multi continental. And that was a sealed Gunvolt.
ZedΩ Gold Trillion Well in the Ballistic Misil stage, we have several feats and statements of ZedΩ Septima Gold Trillion and Septima of the sun capable of controlling the Nuclear Fusion and generate limitless energy.
In him presentation ZedΩ create a mini Sun with him nuclear fusion powers(the same ones descibed to be on par of a real sun because his septima had that powers).
Knowing all that, the next step is determinate the radiation energy for the calc.
The surface area of the sphere is SA=4*pi*r^2, so SA=4*3.14*5^2=314.15m^2
Now to know the radiation energy is P=εAσT^4, P=radiation energy, e is epsilon=emissivity, A=surface area, σ or sigma is Stefan-Boltzmann constant (5.67e-8) and T is temperature. In this case the emissivity was 1.
So, P=1*314.15*5.67e-8*70e6^4=427707800753938268861403876 watts and to transform watts in joules is watts*time.
E=427707800753938268861403876*1s=4.276860566e26J/s or 102 petatons of tnt/Multi continental level.
So if you get a game over with Gunvolt or over uses GV powers in the third game, GV transformed into a primal dragon would nuke the entire planet(in this case i assume is only the surface).
Well, firstly i need to know the Amp of the lightning bolt, in this case the impact area is well all the surface of the planet with a diameter of 12742km and a radius of 6,371km. So the Area is SA=4*pi*6371000m^2=5.100644719e14m^2 and the density of a lightning is 955e+6 A/m^2.
So the AMP is 5.100644719e14m^2*955e6 A/m^2=487,111,570,664,500,000,000,000 amp. And the average lightning volt is 15 millions volts. So the energy in watts is W=amp*V, W=487,111,570,664,500,000,000,000*15000000=7,306,673,559,967,500,000,000,000,000,000 watts.
In Joules is E=W*T in this case the time is the average of a lightning 0.2s, so E=7306673559967500000000000000000*0.2=1.4613347119935e+30 joules/s or 349 exatons or Moon level.
