The hydrogen comes from water. Water is made of hydrogen and oxygen.
So, by applying 50 MWh of electrical energy to 9 tons of water, 8 tons
of oxygen and 1 ton of hydrogen may be made. Water costs about $0.30
per ton, so that's $2.70 - and at $3 per MWh - that's another $150.00
per ton of hydrogen- total costs of $152.70 per ton of hydrogen.

$3 per MWh ?

Generation costs vary widely but for cheap nuclear you might be able to generate 1
kWh AT POINT OF USE for a mere 2 cents (and I'm being really, really generous
there).

That's $20 per MWh.

Where do you get your $3 per MWh electricity from ?

The sun. Check it out.

A cubic meter of PET costs $1200 - rolled into 200 micron thick layers
that's 5,000 layers per cubic meter - each 1 square meter in area -
so, that's $0.24 per square meter. I form these sheets into lens
shaped cavities and join them underwater to form liquid lenses -
inside the liquid lens is a PV die. A 1 sq inch lens focuses sunlight
onto a 0.75 mm square die. It sits IN the water. The front of the
die has a dichroic reflector - acting as a bandpass filter. The back
of the die has A shaped channels that when operating temp is reached,
cause bubbles to form and water to flow without any heat or moving
parts. Forced convection. The PV dies have 40 junctions in series,
increasing voltage,lowering current, and reducing parasitic heating
1,600x. At over 1,000x solar concentration - silicon costs even for
first run crystalline silicon - that would normally cost $12 per watt
- you're only paying $0.012 per watt. 4,608 lenses formed like water
filled bubble wrap - containing 4,608 dies on every 4 ft x 8 ft x 3/4
inch panel - each die 0.75 mm x 0.75 mm - mean with a less than 0.1 mm
kerf - that 92,200 dies can be gotten out of a 300 mm wafer - enough
to populate 20 panels. Processing 250 wafers per hour - allows me to
produce 5000 panels per hour - which is enough for 2 strings per
hour. Each panel produces 540 watts when illuminated - 2.6 MW of
panels per hour - at a cost of $140,000 per hour - total production
cost.

A square a month - 1.75 GW - $120 million - annual costs $10 million -
1,700 hours of sunlight a year - that's 2975 GWh - for $8 million -
1/3 cent per kWh.


Where do you get your 500 nukes from to run it all ? Call it an investment of > $
1 trillion.

Um, I originally thought I'd need $1.6 billion to build a 100 GW per
year plant. But I hit upon using rotary molding techniques - and a
few other processes I want to keep quiet about until the applications
have been filed - but basically we're running at 4 mph web speed - and
hope to increase that to 12 mph or so without any major changes.

haha.. I'm going to be disappearing for a while - so its been fun -
you'll be able to talk about me to your heart's content - haha -
