scary.
maybe they should try VW Blue Antifreeze.
you'd think nuke reactors would be sodium cooled or something ..
water boils so easily.
brings to mind ..
the ever expanding requirement for electricity ..
the first time I ever heard of the idea of tidal flow power generation I
thought that was a brilliant and natural idea.
the force of the tides are humongous ..especially at something like the
narrow mount of a long bay ..
and it's run by the earth and the moon's gravity ..so not likely to break
down for a long time..
a vertical axis turbine can turn the same way ..whether tides or flooding or
ebbing.
They could turn very slowly ..but with great force ...and be geared up a
million rpm to run generators.
I don't think the environmental impact has to be that bad ..
they don't have to block off a whole bay's entrance ..just a third say.
they'd be underwater mostly ..out of site ..not trashing around in the air
like wind generators , and they'd be quiet and I'd think extremely long
lasting .
I don't see why that wouldn't work pretty nicely.
If I had the opportunity I'd build a small private version as a test.
in many places the tides change twice a day ..
a high period, a low period. So that's hours of flow in , then hours of slow
steady HUGE flow out ,
A few places have two high periods and two low periods a day.
The tide levels in places like Alaska can be up to 20 feet.
there are places between islands ..
on the inside Passage ....north of Vancouver Island BC ....places where at
slack tide..
things are calm, and either high or low ..but between ..they are roaring
rapids..
and as long as the water is there, and gravity works, and the moon in orbit
around the earth ..
These generators will be driven.
They don't depend on snow in the mountings to run dams ..
they don't depend on sun to make power..they would work day and night
..cloudy or bright sun.
And they would not depend on wind ..
or fossil fuels or coal or anything like that.
No pollution output.
and there's no waste to store, and no hazardous waste to store for a long,
long time.
What's not to like ! ?
I suppose a good tsunami could wipe out a whole nice installation though ..
but they could be built with that in mind too.
the age of oil will have to end someday ..
and the age of the electron take over.
Already a Nissan Leaf car ( pure EV ) has some noise generator type thing on
it so people can hear it coming ..we are so used to oil-powered sound.
I have a Prius ..possibly one modified to be plug-in too visiting my shop to
have a battery change ..
that'll be interesting.
the cool thing about about a plug-in hybid is there are two ways to put
energy into it ..
well, three really ..
you can add fuel, or charge it ..and when braking it's creating it's own
energy ...good ole gravity charnging the battery.
a Prius should be made so if you can caost it down a long enough
hill....it'll charge it's battery ..so it can go for a while.
Most of the cars in the japan footage IU saw looked like looked like white
cubes.
lucky to be safe.

Red Alert: Japan Warns of Possible Nuclear
Meltdown<http://www.stratfor.com/analysis/20110312-red-alert-japan-warns-possible-nuclear-meltdown>
March 12, 2011 | 0619 GMT

Japanese officials are cautioning that a nuclear meltdown may occur at the
Fukushima Daiichi nuclear power plant near the town of Okuma. According to
Japan’s Jiji Press, some of the reactor’s nuclear fuel rods were briefly
exposed to the air after the reactor’s water levels dropped through
evaporation. A fire engine is currently pumping water into the reactor and
the water levels are recovering, according to an operator of the Tokyo
Electric Power Co. (TEPCO), which operates the plant. A TEPCO spokesman said
the company believes the reactor is not melting down or cracking and that
workers are currently attempting to raise the water level.
If a meltdown takes place — essentially the core of the reactor overheating
and damaging the fuel rods themselves — it would be the first since the
Chernobyl disaster in 1986 and the Three Mile Island incident in 1979.
The Fukushima Daiichi power plant was shut
down<http://www.stratfor.com/analysis/20110311-japanese-nuclear-plant-damaged-earthquake>automatically
on March 11 due to the magnitude
8.9 earthquake that hit
Japan<http://www.stratfor.com/analysis/20110311-earthquake-rocks-japan-generate-tsunami>.
The on-site diesel backup generators also shut down about an hour after the
event, leaving the reactors without power and thus without the ability to
cool down the core. Japanese officials were operating the cooling system via
battery power and were flying in batteries by helicopter to keep the
temperature regulated.
An unchecked rise in temperature could cause the core to essentially turn
into a molten mass that could burn through the reactor vessel. This may lead
to a release of an unchecked amount of radiation into the containment
building that surrounds the reactor. This building could be breached if
enough pressure builds, or, in this case, if the containment building was
already breached through the earlier effects of the earthquake.
At the moment, it would appear that Japanese authorities are still trying to
contain the reaction inside the reactor. That indicates that the core has
not completely melted and that the reaction has not yet gotten out of hand.
However, the situation could quickly become uncontrollable and the added
water being pumped into the reactor could rapidly evaporate if the
temperatures rise too quickly to be cooled off.
