Slow Glass Individualized Service on Mars or Anywhere

For SpaceNut ...

Our recent conversation about "Slow Glass" is best captured at the link: http://newmars.com/forums/viewtopic.php … 61#p160461

I am offering this new top level addition to "Life on Mars" for several reasons:

1) It is completely non-partisan, non-religious, non-ethnic, and should be acceptable to everyone

2) It is literally open to every individual who registers with NewMars.Com/Forum.  Specialized education or experience is not required.

3) It has significant potential as a service which would be desired by many if not most people

4) Initial investment (on the part of a supplier) is (relatively) small, and delivery costs (should be) relatively low.

5) While the target customer base would be people living on Mars, it applies to anyone, anywhere

Summary: A high density video camera would be set up at a customer selected site. Images would be delivered to the customer anywhere.

Model:

At present, on Earth in 2019, there exist a large number of web cams which are free and open to the public, for viewing of scenes of interest (or potential interest) by anyone with access to the Internet.

A friend has a computer with four screens which are normally used for work in the design field.  However, when the computer is not being used for its primary purpose, I observe that three of the screens are typically filled with "live" webcams of scenes from around the Earth.

This example, and discussion with SpaceNut and others in recent days, leads me to visualize "Windows" displayed on high density LED screens, of scenes at the home (or other favorite site) of individuals located anywhere on Earth or away from Earth.

In the case of my friend's display, I note that most sites on display have refresh rates no less than 60 seconds, and often 5 minutes.

Unlike with the free public sites, which are often funded by special interests seeking to attract customers, these would be subscription feeds, designed to serve the psychological needs of individuals seeking to maintain a bond with a location on Earth that has special significance.

I am expecting a corporation to be founded in the not-too-distant future, to compete in the media market place for customers who might be interested in this service. 

If the name is not already taken, or copy-written, or in some other way precluded, I expect to see "Slow Glass Corporation", os something very similar.

With this opening post, I am extending an invitation to every current regular contributor on NewMars forum to post a description of the kind of "Slow Glass" scene they would like to see, if/when the service becomes available.

For readers who do not live in Market oriented societies, this is an example of an inquiry for Market Demand. 

in addition, I am extending an invitation to every current Forum registered member.  The kind of scene that each participant describes will be helpful to an entrepreneur(s) who (I devoutly hope) will invest in building an enterprise to address the potential market.

Finally, if there are Forum readers who have not yet registered, here is a topic that literally ANYONE should be able to join, without fear of contradiction by other members, or other unpleasant experiences that sometimes occur on this occasionally rowdy forum.

Re: Slow Glass Individualized Service on Mars or Anywhere

Leading off ....

SearchTerm:SlowGlass

A slow glass display from my favorite location would have shown fog this (Earth) morning.  Fog occurs in this latitude in the Northern hemisphere at about this time in the Solar cycle.  It's arrival is (for me at least) always unexpected, and it brings back memories of having to drive commercially in such conditions, when I would much rather have stayed in bed.

On the other hand, the arrival of fog brings memories of quiet scenes in many locations, including smells and sounds of fog horns and sea birds all unseen, and perhaps the soft slap of waves on a shore.

Re: Slow Glass Individualized Service on Mars or Anywhere

In the latitude where I live, the leaves of trees are starting to change to fall colors. 

There are a great number of public web cams on Earth today.  In addition (I would imagine) there are numerous private web cams.

Mars residents will (most likely) select streams from those which will be broadcast to Mars as a service. 

Candidates for web cams to be broadcast are many, so I'll list a few and invite others on the forum to contribute to the list.

www.earthcam.com  is a site with multiple feeds

http://obs.astro.ucla.edu/towercam.htm#imagetop  is a site I visit frequently because it is a short distance from the home of a relative.

http://katkam.ca is a site offering a view of English Bay near Vancouver, British Columbia, Canada

www.noao.edu/kpno/kpcam/index.shtml  is a site in the mountain region of the American West, showing a view of two sets of observatories

Re: Slow Glass Individualized Service on Mars or Anywhere

This is the real slow version

of course knowing where and when to go is part of the fall-foliage-prediction-map-fallmaps0819.gif

But seeing it in person is lots  better

Soon we will have another season of cold and snow coming and while some love the outdoors play its the cold that they do not adore...
Me I am partial to mountian views from the peaks and valleys in all seasons.

For SpaceNut re #4 ...

Nice! I like the Autumn theme!

https://www.earthcam.com/usa/newjersey/ … chighlands

The atlantichighlands web cam has a live feed, with a flag fluttering in a mild breeze.  The cost of delivery of a live feed such as this will be significantly greater than still shots taken every minute or every five minutes, but with intelligent data compression, the cost might be reduced. 

The tradeoff is the number of bits required to identify the pixels that change if the compression mode is to only send pixels that change from one frame to another.   I can imagine an automatic switch that sends the raw image if the compressed version exceeds the original in size.

The economic model might well be to send streams of scenes on Mars back to paying customers on Earth.

Even sending the base building in time lasped would be something that some would want, darting about would be dust devils or even a storm....the mars nights would be with moons and stars.

Re: Slow Glass Individualized Service on Mars or Anywhere

Amidst the serious discussion underway in other topics, about numbers of starships needed for Mars settlement, and propulsion chemistry, I'd like to invite anyone interested to take a look out my "Slow Glass" "window" in my hab in Sagan City (2018).

To my amazement, a Blue Jay showed up in the view.  It may be on it's way South, but it may have stopped in because it saw squirrels munching on peanuts.  It took a break at the water bowl (heated now that freezing weather has arrived).

There are still some leaves on the trees, but they are definitely looking raggedy.

A relative and I've been discussing wildlife in our respective locations.

He reported having to trap a raccoon which had (cleverly in my opinion) climbed up the stone chimney and crept under the roof overhang to spend the night.

I had reported missing the ants, which are a feature of life in the 90+ year old house where I live.  Each little worker is (to my way of thinking) a marvel of nanotechnology on full display.  During the warmer seasons, when pulses of workers find their way into crevasses that (obviously) exist, some make there way (unwisely) into view of my ant capture equipment. 

Wisdom may not be the appropriate property to assign to an ant, but a collective of ants often shows remarkable "intelligence" in the art of survival.

Ants are unlikely to be present on Mars during early years, but there may be a way in which they and other insects turn out to be important for a healthy biological infrastructure.

In any case, there are no ants visible in my "Slow Glass" display at this time of the Earth year.

Re: Slow Glass Individualized Service on Mars or Anywhere

Rarely a day (on Earth) goes by that I don't think about what life would be like living on Mars.

The Slow Glass display in my plot in Sagan City (2018) would be showing snow on the ground.

Those who grew up with snow, or with changes of the seasons, may be interested to drop by to see the view.

It would be a good time for serving a hot toddy (whatever that is << grin >>) or just hot coffee (or the artificial equivalent) and reminiscing about adventures on ski slopes or just overland skiing as many do in this part of the globe.

My wife is fond of the winter season and loves snow globes. The other day when the snow was spitting flakes that image came to me so vividly....

Re: Slow Glass Individualized Service on Mars or Anywhere

This is a repost but we can use it instead to see the real mars through it....

Here is a twist on such a technology...but when it comes to mars we will want to make use of daily sunlight just as much as we will artificial.

Punching holes in opaque solar cells turns them transparent

opaque-solar-cell-compared-neutral-colored-transparent-solar-cell-hg.jpg

Existing transparent solar cells tend to have a reddish hue and lower efficiency, but by punching holes that are around 100 um in diameter (comparable in size to a human hair) on crystalline silicon wafers, it allows light through without coloring. The holes are then strategically spaced, so the human eye is unable to "see" the pattern. The best solar cells on the market have an efficiency of over 20 percent. The transparent neutral-colored solar cell that the research team developed demonstrated long-term stability with a high-power conversion efficiency of 12.2 percent. The next step for the team is to scale up the device to 25 cm2 (3.88 in2) and increase the efficiency to 15 percent. Furthermore, most windows are vertically placed, which causes light to hit the windows at a low angle. When hit by low angle light, the electrical current in conventional cells drops nearly 30 percent, while transparent solar cells reduce less than 4 percent--allowing it to utilize solar energy more efficiently.

Research Report: "Neutral-Colored Transparent Crystalline Silicon Photovoltaics"

This makes it ideal for solar concentrated light to pass as well as to get the energy from the reflected light. This is a benefit to a natural lighted as the panels now become part of the construction and not extra mass to supply energy.
