BradGuth said:I agree, that our badly failing environment needs that do or die kick
in the butt, whereas the all electric car is technically doable,
especially with the enviro safe and clean h2o2/aluminum battery, along
with as much global renewable energy that's put in charge of producing
the h2o2 and aluminum.
However, there's no such thing as 100% safe energy, or even of those
products made with said energy. I'm certain there will be those
deaths associated with getting fusion energy up and running,
especially if any of that required bulk or volume of He3 is derived
from our moon.
Klondike III wind project: tower failre likely due to excessive
torque.

Chadd Mitchell, 35, was killed on Saturday afternoon when a 242-foot-
tall tower he was working on toppled over, said a dispatcher for the
Sherman County Sheriff's Department.
Mitchell, of Goldendale, Washington, was working at the top of the
tower -- essentially a hollow tube -- when it buckled. A second worker
in the tube was injured and a third worker on the ground was not hurt,
according to The Oregonian newspaper. Federal officials are
investigating the incident, it said.
"the turbine blades were manufactured in Denmark and the towers in the
United States"
"The specific tower, W-1, was located at the easternmost row of towers
in the Klondike III project"

Oddly there's no specific mention of the tower engineering firm or of
those in charge of having built such towers.

Jim Johnson, a mechanical engineer with the federal National Renewable
Energy Lab's wind technology center, discounted the possibility of a
structurally deficient tower.
"It's not impossible, but it's extremely unlikely for a tower to be at
fault on its own and to buckle and fall," he said.
But Johnson also found it difficult to come up with a scenario under
which the blades turned quickly enough and the braking systems came on
suddenly enough to torque or vibrate and buckle the tower.
Paul Gipe of the Ontario Sustainable Energy Association in Toronto
maintains the only worldwide database on wind tower deaths.
According to his figures, there have been 33 previous deaths
worldwide associated with wind towers since 1975, with 18 of them in
the United States.
The most recent accidental death took place when a worker fell 210
feet in Chandler, Minn. in 2005
Last year, a wind gust bent and twisted a tower at the Condon
Wind Project in Gilliam County, but there were no injuries associated
with that accident.

Obviously the rotational braking torque was unavoidably 100%
transferred into twisting that support tower, and with that tonnage of
blades in motion along with maximum braking applied would have placed
all of that rotational energy into the tower itself. Why such blades
have to be so decelerated to such a complete stop and so quickly is
clearly not understood. I'd like a look-see at the mechanical specs
and results of subsequent testing of those towers, which obviously had
little if any structural reserve to work safely within such torque
issues.
Americans seem genetically mutated as to specialize in cutting corners
at every opportunity, and then some. Hopefully our future of He3
fusion derived energy will become as robust and reliable as my LSE-CM/
ISS. Otherwise, we know that most anything of fossil and yellowcake
derived energy is birth to grave deadly in more spendy, lethal and
toxic ways than we can count, not to mention the ongoing collateral
damage and carnage of the innocent related to 9/11 and our ongoing
efforts at taking control of Iracq's oil.

Forget it. We are already past the point of no return. Yes, co2 is
increasing greenhouse but particulates are blocking sun light. When we
clean the particulate emissions out of the air the temperature will
double, melt all the glaciers left and kill mankind.
