We compute the total power P by multiplying the far-away redshifted energy density by the area A of the horizon. This may be a conceptual error in Hawking's original estimate of black hole evaporation time. The clock hovering at L distant from A is running much faster than our far away clock where we are. A is an infinite redshift surface, but including L makes it finite but large. Also it takes infinite far away clock time for objects to reach A etc.
 
Therefore, we can argue that the Wikipedia calculation is wrong. That is, for Hawking's surface gravity case, replace
 
P ~ A (energy density) ~ A^-1
 
by
 
P ~ g00(L)^1/2A (energy density)
~  [1 + z(L)]^-1A (energy density)
~ (L/A^1/2)^1/2A^-1
 
 
Therefore, even in Hawking's case, 
 
P ~ dM/dt ~ L^1/2/A^5/4
 
Therefore,
 
dM/dt ~ L^1/2/M^5/2
 
tHawking ~ M^7/2 /L^1/2  not M^3
 
remember there is no actual evidence for M^3.
 
Next our new case
 
Instead of
 
P' ~ AT'^4 ~ A/L^2A ~ L^-2 ~ mp^-2
 
dM'/dt ~ mp^-2
 
P' ~ [1 + z(L)]^-1AT'^4
~ (L^1/2/A^1/4)A/L^2A
~ 1/L^1/2A^1/4
 
dM'/dt ~ 1/L^1/2M^1/2
 
t' ~ L^1/2M^3/2

to be continued

Stefan–Boltzmann–Schwarzschild–Hawking black hole radiation power law derivation:
For a solar mass black hole
Putting in the gravity time dilation factor L^1/2/A^1/4
 
L ~ 10^-35 meters
 
L^1/2 ~ (1/3) 10^-17
 
A^1/2 ~ 10^3 meters

A^1/4 ~ 3 x10
 
L^1/2/A^1/4 ~ 10^-17/3x3s10 ~ 10^-19
 
so
 
P ~ 10^-28 x 10^-19 ~ 10^-47 watts
 
Next for our gravity radiation
 
 
P' ~ [1 + z(L)]^-1AT'^4 ~ (L^1/2/A^1/4)A/L^2A ~ 1/L^1/2A^1/4

http://en.wikipedia.org/wiki/Stefan–Boltzmann_constant
 
P' ~ 6 x 10^-8T'^4
 
Our T' = (A^1/2/L)^1/2T ~  10^23(M/mp)^1/2(1/M) ~ 10^23/(mpM)^1/2  deg K
 
Therefore, energy density is
 
6 x 10^-8 x 10^92/mp^2M^2
 
Multiply by the area A and the gravity time dilation factor L^1/2/A^1/4
 
So that's effective area    L^1/2A^3/4
 
Total power is then
 
P' ~ 10^85 L^1/2A^3/4/mp^2M^2  Watts
 
for a solar mass scale black hole that's roughly
 
P' ~ 10^85 (1/3) 10^-17 (10^6^)3/4 10^10 x 10^-60  Watts
 
P' ~ 10^23 Watts - very roughly in gravity wave black body radiation ~ 
 
peak wavelength ~ 10^-16 meters ~ 10^24 Hz
 
to be continued - next order of biz evaporation lifetime

The 10^23 Watts is only the initial output - that increases as the black hole evaporates

In our new theory this is I think
 
t'ev = c^2(mpM)^3/2 /3Kev 
 
(mpM)^3/2 = xM^3
 
x = (mpM)^3/2/M = (mp/M)^3/2
 
t'ev = (mp/M)^3/2 tev ~  (mp/M)^3/2 10^-16[M/kg]^3
 
For a ~ solar mass black hole 
 
(10^ -35)3/2 10^67 years ~ 10^-52 10^67 ~ 10^15 years

From the beginning:
 
First Hawking
 
L = Schwarzschild radial coordinate distance to horizon classical 2D surface g00 = 0.
 
Newton's surface gravity ~ A^-1/2
 
A = area-entropy of g00 = 0
 
What they do in Wikipedia above comes down to this
 
Redshifted Unruh temperature a long distant from the black hole is
 
THawking ~ A^-1/2
 
Stefan-Boltzmann law
 
energy density ~ THawking^4 ~ A^-2
 
Total redshifted power
 
P ~ A (energy density) ~ A^-1
 
A ~ M^2
 
P ~ dM/dt
 
tlifetime ~ M^3
 
OK now my new prediction following the same argument as above
 
The redshifted thickness gravity Unruh temperature is
 
T' ~ (LA^1/2)^-1/2
 
If we take
 
Lp ~ mp = Planck mass
 
T' ~ (mpM)^-1/2
 
P' ~ AT'^4 ~ A/L^2A ~ L^-2 ~ mp^-2
 
dM'/dt ~ mp^-2
 
t' ~ mp^2M << t ~ M^3
