Norman works at Ropley, one of the Stations on the Watercress Line, a preserved steam railway that connects Alton and Alresford in Hampshire, England.
Norman is most definitely happy in his work, a long serving volunteer who has had a role on the line since the early 1980s.
The sun lit him up as if it would always be so and not knowing how I was framing the shot he held his hands, blackened by the day's grease and coal behind his back.
Happy with his lot, Norman didn't take long to tell me of the times gone by when he was to be found on the locomotives' footplates. It seems sad, but probably not all bad that at the age of 86 he is now kept busy elsewhere.
I somehow got the impression that he would still occasionally be found, up where he belongs, in the engine room.

Three Levels of passive solar energy use for homes:
Pragmatic:
Many detached suburban houses can achieve reductions in heating expense without obvious changes to their appearance, comfort or usability.
This is done using good siting and window positioning, small amounts of thermal mass, with good but conventional insulation and occasional supplementary heat from a central radiator connected to a water heater.
Sunrays may fall onto a wall during the daytime, which will radiate heat in the evening.
Annualized:
Historically, most "passive solar" approaches have depended on near-daily solar capture and storage, only expected to maintain temperatures through a few days and nights. These are now termed "short-cycle passive solar".
More recent research has developed techniques to capture warm-season solar heat, convey it to a seasonal thermal store for use months later during the cool or cold season. This is referred to as "annualized passive solar." This requires large amounts of thermal mass. One technique buries water-proof insulation in 7-metre skirts around the foundation, and buries loops of plastic pipe or ducts under the foundations and slab. The "skirts" of insulation prevent heat leaks from weather or water.
Minimum machinery:
A "purely passive" solar-heated house would have no mechanical furnace unit, relying instead on energy captured from sunshine, only supplemented by "incidental" heat energy given off by lights, candles , other task-specific appliances (such as those for cooking, entertainment, etc.), showering, people and pets. The use of natural air currents (rather than mechanical devices such as fans) to circulate air is related, though not strictly solar design.

So, I tried something a little different in processing. Let me know what you think! This is my 1st try at brush/paint.

The term solar panel is best applied to a flat solar thermal collector, such as a solar hot water or air panel used to heat water, air, or otherwise collect solar thermal energy. But 'solar panel' may also refer to a photovoltaic module which is an assembly of solar cells used to generate electricity. In all cases, the panels are typically flat, and are available in various heights and widths.
An array is an assembly of solar-thermal panels or photovoltaic (PV) modules; the panels can be connected either in parallel or series depending upon the design objective. Solar panels typically find use in residential, commercial, institutional, and light industrial applications.
Solar-thermal panels saw widespread use in Florida and California until the 1920s when tank-type water heaters replaced them. A thriving manufacturing business soon dwindled. However, solar-thermal panels are still in production, and are common in portions of the world where energy costs, and solar energy availability, are high as a direct result of today’s global warming effects .
Recently there has been a surge toward large scale production of PV modules. In parts of the world with significantly high insolation levels, PV output and their economics are enhanced. PV modules are the primary component of most small-scale solar-electric power generating facilities. Larger facilities, such as solar power plants typically contain an array of reflectors (concentrators), a receiver, and a thermodynamic power cycle, and thus use solar-thermal rather than PV.
The largest solar panel in the world is under construction in the south of Portugal. A 116-megawatt facility covering a 250-hectare south-facing hillside in the southern Alentejo region and it will produce electricity for 25,000 households.

Solar Street Light - Energy from the Sun

Solar radiation reaches the Earth's upper atmosphere at a rate of 1366 watts per square meter (W/m2).
While traveling through the atmosphere 6% of the incoming solar radiation (insolation) is reflected and 16% is absorbed resulting in a peak irradiance at the equator of 1,020 W/m². Average atmospheric conditions (clouds, dust, pollutants) further reduce insolation by 20% through reflection and 3% through absorption.
Atmospheric conditions not only reduce the quantity of insolation reaching the Earth's surface but also affect the quality of insolation by diffusing incoming light and altering its spectrum.
After passing through the Earth's atmosphere, most of the sun's energy is in the form of visible and Infrared radiations. Plants use solar energy to create chemical energy through photosynthesis. Humans regularly use this energy burning wood or fossil fuels, or when simply eating the plants.
A recent concern is "Global Dimming" an effect of pollution that is allowing less sunlight to reach the Earth's surface. It is intricately linked with pollution particles and global warming, and it is mostly of concern for issues of global climate change, but is also of concern to proponents of solar power because of the existing and potential future decreases in available solar energy. The order of magnitude is about 4% less solar energy available at sea level over the timeframe of 1961–90, mostly from increased reflection from clouds back into outer space.
The proceeds will fund the construction and operation of three 48MW wind farms sponsored by the same local company in Quang Tri Province, Viet Nam.

External shutter voltage.
The VS14s Uniblitz shutter need 65V nominal as working voltage. I have build a DC/DC convertor to boost the voltage from the 7.2v battery to 67V on a 820 uF/330V Flash-elco. An ATtiny26 AVR controller is used to control the DC/DC module.
The external VS14s shutter need a 4 msec puls to full open in 3.5msec. The 67V elco is used as powersystem to drive the high current during this short time. On this scoop picture, you see the elco discharge during this 4ms. The DC/DC convertor has to compensate as quick as possible to be ready for the next shutter sequence. The DC/DC convertor load the elco in 228 msec. The camera is set to 3 pictures/sec in repeat mode. the DC / DC converter is fast enough to keep up the 67V between the shots.
The old hardware in test is show here:

External shutter DC/DC convertor module.

The tests with different inductors results into a working version where the primair load from 20V to 67V goes into 575ms. This time is only for the first powerup faze. Once on the 67V working voltage the convertor has only shortly to wakeup the voltage due to the small own internal discharge current. To see how the voltage change due to the shutter activation see:
