BVI

Bay

Time for a vacation. Four classmates from our Dental School class of 79 and I head down to the British Virgin Islands.  We’re ready to sit down over the local beverage and discuss thirty-five years of our profession……and retirement!

SV J-Pharoum

First, we rent one of these–big and roomy and idiot-proof.  But Glen is an expert sailor and I’ve a broken leg.  The doctor said lots of ice so I’m not going to disappoint!

Bay 2

Ah!  The serene evenings at anchor.  This is much preferred over beating down Chatham Straits in Alaska taking 35 knots on the nose.

Dinner

Meet Dennis, Jeff, Glenn, Jim and your’s truly.  We didn’t have a bad meal either–fresh catch every night.

Ketch

This is the typical view from the helm…..

Water spout

 

Check out this water spout.  We had two days of real sailing weather and Glen did a grand job.  And I didn’t disappoint my doctor either…..  Stay tuned.

Coast Redwoods

Big Trees 2

Several years ago, we visited Sequoia and Kings Canyon National Parks but not the Coast Redwoods.  After our annual NPS trade show meeting in Portland, Redwood National and State Parks invited us to visit and perhaps make a screened print to fit our series.

Tradeshow Staff

Here’s our trade show–our 20th year!  We post on Facebook also. This year the meeting was held in Portland and we brought the whole gang.  Chuck Ziga of Ziga Media even attended from Connecticut–he publishes our calendars.  Afterwards, we all (well most) headed for the famous Oregon Pinot wine country to celebrate this anniversary. The next day, Ranger Doug and his sidekick Martina rode south to the big trees….

Big Trees

These are truly magnificent forests–and consider 95% of these trees have been harvested by the timber companies.  In 1918, the Save the Redwoods League formed and began buying up groves assembling a chain of preserves along the northern California coast now managed jointly by the National Park Service and the California State Parks.

Another Big Tree

These trees were not harvested for fancy wood products, but chopped up on sight and trucked down to the Central Valley and San Joaquin Valley mostly for grape stakes and picnic tables.  The harvesting of Redwoods continues to this day….and so does the League.

When you visit, make sure to stop at the Visitor Centers–this one at Prairie Creek–built by the CCC.

Here is the interior with a beautiful fireplace.

Big Tree

Here’s another big tree called Big Tree.  It’s over 300′ high.  The Coast Redwood (Sequoia sempervirens) is 100′ taller than their mountainous Sequoia cousins.  Forest floors are filled with fern and rhododendrons.  This is spotted owl country!

 JD Grove

Wow! And we’re looking at about 5% that’s left.

Theater

In Eureka, we stopped by an old theater for a photo op. Lots of roadside attractions here.

Second Babe

Here’s one.  A 40′ concrete Paul Bunyan and his anatomically correct “Babe” the Blue Ox.  We stumbled into the little museum here and were blown away by Marylee Smith’s collections of Indian art and artifacts; defined as the largest private collection of it’s kind.

Museum

This was worth the drive alone.  Don’t miss this stop.

Tree House

Or this one–the World Famous Tree House.  We must push on to Wyoming so we drive south, but not before I break my leg tripping on a stage enroute to a piano.   I’ve always been a sucker for pianos and didn’t see the dimly lit raised stage.  Tore my knee all apart so I’m now languishing in Jackson Hole while everyone tweets their skiing to me……Stay tuned!

Winter Solstice & Otter Slides

December 20th, 2012

Tomorrow is the winter solstice–which is the shortest day of the year in the northern hemisphere.  These panels are located at 56.8027° N, 132.9935° W, the sun rises at 8:26 am and sets at 3:14 pm for a 6 hour and 47 minute long day.  Google Earth just put up a very hi-resolution view of Petersburg–take a peek here on this very cool lat/lon calculator.    And today at least the sun is out.

This is all we get although this was taken about 10:30 am; somewhat less than the 9.73 degrees above the horizon we’ll expect at 11:51 am tomorrow.  The Arctic Circle will see the sun on the horizon briefly at noon–Fort Yukon lies right on this line (which moves about 25′ a year due to the wobble of the earth).

This is the backside of our 12 solar panels.  These wires pack about 132 VDC on a nice sunny cold day.   I’ve made adjustable poles to tilt the panels as the earth swings around the sun to the summer solstice in 180 days.  Here, they’re about 33 degrees from vertical–I forgot to shift them more upright to the winter position in October (about 21 degrees from vertical).   I’ve a summer position, a winter position and a midway (equinox) position.  I’m good til February 18 when the sun is back 11.7 degrees up from the winter low at which time I’ll go back to the middle position and await the summer solstice on June 21.  An equal time thereafter, August 22 when the sun is 11.7 degrees down from it’s solstice, it’s back to the middle again.  Man I’m getting dizzy just thinking about it.  Many plants and flowers automatically track the sun daily–boy is this a crude system but we’re off the grid and must do it manually.  If you want to calculate the angle of the sun from anywhere on earth and any time of day click here.

Not much current flowing today even though it’s clear.  Sixty-two volts putting out 233 watts at this time–telling me one panel is off line (I’ve divided the 12 panels). Turns out it’s snow and ice on the first panel seen in the first photo here.  I should be getting about 132VDC.    Ohm’s Law is Amps X Volts = Watts but there is some resistance here.   The total power generated is 100 watts/hour (since midnight) or enough to run a 100w light bulb for an hour–well, this is our slowest solar time.  In peak summer sun, we’ll get 8.1kwh; more than enough to run everything.   All this is stored in eight L-16 lead-acid batteries which are slowly dying off after 6 years of constant use.  They ran dry once–not good but we’ve ordered 40 (yes, forty) new nickel-iron “Edison” batteries which are now produced in China.  These NiFe batteries essentially last forever & can’t freeze; but they’re spendy…..

This big fuel barge happened by this morning–our lifelink to the rest of the world and the reason we’re going solar (and hydro).  All the mountains are proudly displayed here in our front yard.

Here is the moonrise the same afternoon.  Yesterday, I went out and got a shore pine xmas tree–they grow very slowly and have a nice full shape.  I slurried it down the hill with much rigor working up quite a sweat–good exercise.  Then I stumbled upon these tracks:

This slide went on for 20-30′ at a time with little push mark footprints….a river otter simply out having fun.  Olaus Murie, in his book Animal Tracks says these animals will tuck their front paws to the side and skid on their stomachs with an occasional kick/glide much like a cross country skier.  This guy covered a lot of ground!  My snowshoe tracks lower left for scale.  Tonight a solstice fire on the beach with eggnog & friends–stay tuned and Happy Holidays all!
