To get 3.6MW even with 50% efficiency, you'd need to capture sunlight
over an area of 7200 square metres. For example, approximately a square
85 metres by 85 metres. Nothing at those sites is anything like that big.


In fact there is a 40x50 foot metal building there.


That's a long way short of 85 metres by 85 metres.

But see that dark spot just to its right?


I thought that was the privy.

Supposedly there's deep ocean methane deposits just sitting there, and
though risky and spendy to extract, it'll likely become necessary by
the end of this century if we're going to stretch out our global
hydrocarbons for another 300 years. But then what?

At best, the USA only imported a little over 20 million barrels per
year from Libya before everything turned ugly, which is hardly a drop
in the overall Big Energy bucket that's currently making us pay more
than $4/gallon (with their summer sights set on $5/gallon). In other
words, the disruption to the US market is only shot us down by at most
a couple million barrels thus far, although I'd bet we've only missed
out on one supertanker load, because if anyone can get a supertanker
hauling a million barrels of Libyan oil safely underway, that would be
us.

I'm certain that you and others (including William Mook) can add a
great deal of valuable history and current event information to this
most recent topic by Michael Moore.

http://www.michaelmoore.com/words/mi...a-is-not-broke
It seems our very own homegrown banking, investment and insurance
cabals of monetary terrorist have each gotten the Rothschild green
light and their stamp of approval.

Any time a government agency or their special ops and hired
mercenaries need loot and/or spendy resources, there’s never any
shortage. Just like when the rich and powerful decide to play
monopoly with public and privet loot that’s leveraged way past the
point of no return as is, there’s little if anything to fear as long
as those offshore banks and stealth investments are being kept as
covert or secret and untaxable to boot.

So, unless your God has a robust ledger of offshore accounts stuffed
with loot and other precious resources, it’s unlikely that the rich
and powerful that are above government and in charge of most
everything that counts, have anything to fear.

Hopefully humane will learn to use other energy sources in just a few
decades, Brad!

Such as Mokenergy hydrogen derived from solar energy would be a good
start, even if that started out badly at $1000/tonne, because that's
still only 5 cents/kwhr when derived from a Bloom fuel cell unit.
Once solar energy is fully developed should bring that delivered
hydrogen cost near $100/tonne, and Mook has many other clean synfuel
from coal alternatives that shouldn't be excluded.

Of course I'm all for creating and using HTP, as well geothermal in
addition to wind, solar and maximum hydroelectric, not to mention my
support for those failsafe thorium fueled reactors.

Big Energy insider traders and market speculators are taking us to the
cleaners. In legal terms of extortion, that’s essentially treason, if
not an act of war.

At best, the USA only imported a little over 20 million barrels per
year from Libya before everything turned ugly (that’s roughly a day’s
worth), which is hardly a drop in the overall Big Energy bucket that's
currently making us pay more than $4/gallon (with their summer sights
set on $5/gallon). In other words, the disruption to the US market is
only shot us down by at most a couple million barrels thus far,

True! Any new source will have to be adopted. Brookhaven Labs did a
study for JFK back in 1963 detailing how to take a few very high
temperature nuclear reactors and use them to thermolytically reduce
water into hydrogen Then, use that hydrogen to power stationary
thermal plants with them, and use the stranded fossil fuels along with
more hydrogen if needed, to supply liquid transportation fuels. This
is the quickest way to end our reliance on extracting oil from the
ground.

The only high temperature nuclear source of energy I have access to is
the sun. The big problem here is that it costs about $144 per square
foot to collect sunlight using conventional wafers modified to capture
sunlight, and you only get 200 Watts or so of DC power when the sun
shines. This is $7 per peak watt and is not competitive. Can make
hydrogen from water through electrolysis. While this solves the
storage problems, it increases costs and reduces overall efficiency.
Making things worse.

So you've got to reduce costs. That's what I've done over the past 15
years. You can do lots of things to reduce costs. One of these is to
focus the light 5,000x the intensity its found on Earth. This reduces
the cost from $7 per peak watt to less than a penny per peak watt.
When you do that you have tremendous heating. You solve that by
immersing the photocell in water - in fact using water filled cavities
as lensing media - and coat the cell with dichroic material that
reflects away ineffective photons. This is the basis of my patents
and patent applications - a few of which are reproduced here

http://www.scribd.com/doc/21832226/M...ectral-Cooling
http://www.scribd.com/doc/20047598/M...a-low-cost-CPV

With these techniques its possible to produce solar panels that are
less than $0.07 per peak watt and produce hydrogen at $100 per ton.

http://www.scribd.com/doc/20024194/P...rom-Mok-Report

With hydrogen at this cost, hydrocarbon fuels are made at below market
prices and are immediately marketable through the various exchanges
set up to trade future production of oil products

Something which I attempted to do

But was stalled when ASTM refused to certify coal derived liquids for
trading until 2016

Which I gave an interview about
