Solar or renewables Will we make it

You may forward this to anybody. This may be my Post
doc application or cover letter or a problem to keep in mind
and discuss before I do my professionship. This is written for
mobile viewing. Will we be able to produce so much energy
that we are in excess than even the solar production rate and
invest in water hydrolysis as a storge. Lets have fun. All
Changes to version will have a section. These calculations
were done writing to a few people and discussing at home.

60 years of fossils. 1000 years of nuclear at 375 Re per watt
Eyear=1e19 Wh/year.
E=1e19Wh/year * 60 years Property=E*cost
Pow=1e19Wh/3600/365 Solar=40rupee per watt Cost=6
rupee per Kwh
Costsol=Pow*Solar/3600/365*cost
ratio= Property/costsol =1800 thus at some point we would
be all solar and wind which is equally costly
Cost oer year=6e13 re 2 lakh cr= 2e13
So we must invest 1/1000 or 1/100 of GDP in SOlar.
We invest about 2GW a year or 1e11 a year
Thus, if panels or wind fail in 30 years can we exist in 60
years and build ssion reactors.
If we have X kWhr of fossil and it costs y kwhrs/kw which
fails in tf hrs, we use z kw, we have X/z hrs of life. If we
invest p percent per year into solar, and it gen nothing, we
have X(1-p)/z years. Solar capacity is Xp/y. We are investing
1/1000 an year and we arrived that we need to invest 1/1800.
So it might be just enough for India to survive. Oh there is
a problem. The life of panels is only 30 years. So It's super
complex. Abengoa is the best company. I didn't take my
extended desktop there and had to quit. So what's your bet
can we build a self consistent solar panel investment model to
be immortal as humans . 5re? I don't know how to bring step
function into the calculation. What did babies give a revision
for teachers and thus a revision for higher profs.. So we should
have babies till the end. If fossil then 60. We have enough n
fuel for 1000. But do we have enough to build ? Nuclear costs
375 re per W.
The right questions are what's the life time etc. If we can
just build solar panels can we build nuclear ssion reactors
within 60 years if cost is 10 times? Setting up quittich match
where the golden snitch is to solve the energy sustainance prob-
lem. Don't know what other physicists are solving. The other
team is laziness funding etc.
Caught the golden snitch. Need to express step with expo-
nentials and laplace transform. Will take some time to solve
it.

Even if nuclear is 1000 years, what technology can we invent in
the next 1000 years to extend it for 10000. Things like fusion
come up.
