Embedding Server Farms where the Power is

When Google or Microsoft want to build a server farm they do their best to build their facilities as close to major energy sources as possible.  The logic behind building their server farms close to energy sources is relatively simple the power is cheapest closest to the source.  Both companies have stated sustainability goals, Google to have all of its power produced by renewable energy sources and Microsoft to become carbon neutral, these sustainability goals, combined with our society's ravenous desire for cloud based services mean that unique solutions for powering server farms will become necessary as time goes on.  

Currently the majority of server farms are massive facilities covering thousands of square feet, what I would like to suggest is a complimentary server farm design that is intended to work with more distributed energy sources.  Instead of massive facilities organizations could invest in smaller systems designed to be installed right next to large scale wind turbines and solar arrays.  Under normal operations the distributed servers would operate at some baseline of data processing, when surplus power is being produced the servers would do scale up how much data they would crunch. 

These servers would most likely make the most sense serving as supplemental archival storage capacity and large scale data crunching where the time the processing completion time is more flexible.  The utilization of this capacity could be implimented in a range of ways, the servers could be owned out right by either cloud service providers, the power producer, or a 3rd party owner operator.  

Hopefully these smaller server arrays would also benefit from increased surface area, said increased surface area would mean more space for hot air to escape, assuming solar gain was not excessive.

Window Heating Units

As an Alaskan transplanted to the New England area, my battle with the summer heat has been a constant uphill struggle to find some kind of happy medium to keep my core temperature from becoming entirely unpleasant.  My current solution has been to have a window AC unit at home set to as close to glacial as physically possible.  Come winter I have a different problem of not wanting to spend excessive money on keeping my apartment warm.  In an ideal world my residence would have thermostats in each individual room so that my bedroom was toasty, the living room pleasant, and if I magically had any other rooms in the space they wouldn't be huge energy draws.  In a more realistic version of reality getting a rented apartment to have a highly granular zoned temperature control is unlikely, so how is a renter to reduce their apartment's heating costs.  REVERSE AIR-CONDITIONING otherwise known as "Air Source Heat Pumps" can be used to capture the thermal energy of the outdoors (yes, if it is above zero degrees Fahrenheit, possibly colder, you can harvest thermal energy from the ambient air).

Currently there are a range of these heating systems available for general consumption, but none of them, according to my ten minute web search, are designed to be seasonally added to a window sill.  The benefit of this could be huge, instead of home owners buying incredibly inefficient heating element style home heating systems, consumers could buy a smart window unit that would capture ambient outdoor energy.

 Design challenges would be great, but not insurmountable. The total cost of the unit would need to achieve a reasonably short ROI, preferably less than three years, ideally less than one.   Cost consideration is where a clever business plan is most important.  Depending on the actual material cost of this system home-owners might balk at the up-front cost and not buy in, regardless of long term saving potential, so how do you get people to invest in a long term money saver, options include but are not limited to a model similar to roof top solar companies that rent your roof space and sell you the power.  The window heat pumps would not be owned by the home owner, but by a leasing organization, where the home-owner/renter simply buys the hot air from the company (some political joke here).  Power producers that identify customers who use electrical heating in their space could provide financial incentives to offset the cost to the consumer.  The window system would need to weigh no more than that of a currently available window AC unit that consumers would use in the summer.  After cost and weight are accounted for in the design, ease of use and ideally overall attractiveness of the design should then be accounted for.

Down the line dream features, the system can change which side it is pumping heat to and from, cooling in the summer, warming in the winter.  Connectivity to smart home systems, allowing the unit to know when to crank up the heat, ideally it could work with other systems in the home in concert, allowing for finer control of home energy use.

An alternative technology that I am unsure if it deserves its own post, so I will write it down here for the moment.

Smart blinds and curtains.  Windows can allow for a large amount of thermal energy to enter or escape the home, even well insulated windows can allow the energy of visible spectrum light to come and go as it pleases.  Well designed window coverings could offset some of a home's energy use (I'm going to need to look into that particular number 7/27).  On hot days in the summer, when no one is home, the smart blinds would lower a white and or silver curtain intended to reflect away excess sunlight.  In the winter the blinds would lower a darker covering designed to convert the visible energy of the light into thermal energy that would go into the house.  A very simple version of this system would use a small solar panel to power itself (or plug if need be) and use two types of curtains, one black one reflective to cool the house.  More sophisticated versions would use either smart materials or several layers of curtain material to give finer control of the amount of light allowed in and energy converted.

The FreshStart Phone

A few days ago a friend of mine texted me asking about how hard it would be to embed solar panels in a low cost cellphone, so that individuals who for whatever reason were trying to get established, would have some way to communicate with their healthcare provider, parole officer, who ever they needed to reach out to to get back on their feet.  The core sentiment is an excellent one, provide a resource for those who are at the greatest risk to engage with society, my primary point of feedback was the power output of the solar panel.  Even under the best circumstances the available surface area of a cellphone would have a hard time collecting enough sunlight to conveniently charge a cellphone.  (I may do the math showing this later, but for the moment I am just going to keep the work conceptual)
Just because a cellphone would have a hard time being charged by sunlight does not mean we as a society couldn't create a device that would be truly useful to those less enfranchised.
Whatever design that is eventually developed it will need to meet a rather challenging list of constraints.  The design suggestions I am putting forth below are just one way a product could be designed to meet a user's needs but I feel it would represent what individuals  might desire in their smart device.  My temporary title for this phone is the FreshStart, if someone in marketing wants to change it, great, I never said I was great at naming things.

The biggest limiting factor is cost, no matter how you want to slice it the primary customers of our starter phone are not the end users, but organizations that need to be able to buy hundreds, if not thousands of devices without destroying their budget. While I have no idea how much per unit either the governments of the world or non-profits would be willing to go, I am going to assume that these phones are being distributed in countries like the US and as such a maximum price of $50 is far from unreasonable.  Current Nokia feature phones cost something like $30 so it shouldn't be that unreasonable to keep the dollar cost of the device close to that.

After cost comes reliability, the device needs to be physically tough and have a very high endurance.  Users may not be guaranteed the opportunity to charge their phone every day and so the battery capacity should reflect the need for going several days without charging.

Close after reliability is attractiveness of the device, users need to feel like the phone they are getting is something important and worth holding onto, it may be free to them, but it should also be something that they value for more than the phone calls.

So far I am reasonably describing currently available feature phones, many now have very excellent run times, so long as they are only used for calls and texting they can work for days. Personally I enjoy the simple look of the Nokia style brick phones (this could be a result of early 2000's nostalgia.)  What would be a distinguishing characteristic of the design is integrating the charger, the majority of phones require you to have a second piece of hardware to charge your phone.  By integrating  the charger you are reducing the number of things someone has to keep track of.  The FreshStart's back would have a simple two prong A/C connector that would allow the device to be directly plugged into a wall  outlet.  To compliment the A/C adapter and to acknowledge the fact that individuals are mobile and may not have a long period of time near an outlet, for example the time it takes for them to finish their coffee, the FreshStart would have part of its battery capacity be a non-removable high endurance rapid charging element, either an ultra-capacitor or an optimized breed of battery that I can't think of right now.  This batter would be intended to charge in under 2 minutes while providing enough energy for ten times or more run time, ideally several hours of use.

Additional features that would be nice but not required, built in USB ports to allow other devices to charge while the phone itself charges, a USB plug to allow the use of charging ports that are now showing up in cities, a flashlight, an E-Ink display.

As of now this is as far as I've gotten with the FreshStart's concept, when I get back to my desktop with CADsoftware I will try to create a 3-D render.

Dear Electronics Manufacturers, Stop Keeping Me Up at NIght

Years ago I recall reading an article noting the reason why electronics devices have bright LEDs is that manufacturers want consumers to pay more attention to their product on show room floors, but most of us don't live in a showroom, so why do the LEDs remain at the same brightness?  Honestly, I'm going to blame some corporate marketing genius, but I HAZ SOLUTION!

Photo resistors, that's right, simple photoresistors.

Manufacturers could readily embed one or more micro light sensors, that would provide feed back into the power supply of any visible spectrum LEDs.  Using a relatively simple PWM on the power of the LED, your device could dim its lights in real world conditions but still be annoyingly bright on the showroom.  

Unfortunately the reason technology like this isn't implemented isn't a result of lack of technology, it's a result of lack of incentives for them to make this feature common place.

7/15/15 Follow Up

Option B, instead of using circuits that add to the cost and complexity of manufacturing electronics lighting, sticky pads.  Using the same style of adhesive that painters tape and Post It Notes (tm), make pads of material that are designed to cover individual LEDs.  A company could make a generic pad that covers a given area, read a square of material, or you could get customized pieces that more closely match a given device.

The reason for this, I hate putting pieces of tape on my electronics, but it seems like it is the only way to ensure that my bedroom isn't a damn glow cave

Updating the Igloo

On Monday afternoon I got a text from a friend asking if we could use Arctic Ice and plastic sheeting to make buildings in extreme northern/southern latitudes.  To which I asked "you mean an igloo?"  After some clarification it became obvious that he was hoping for something a tad more modern, and when there is a convergence of an upcoming technical job interview where one's design methodologies are being inquired on and the "client" is an old friend, what the hey?

The challenge for this design request is how generally vague it is, Forrest this is no disservice to you, I know it was a random idea communicated via a small number of text messages.  The goal, generally stated is to design a technology or series of technologies that allow teams to use local resources to set up housing that can survive extreme weather.  The other general restrictions are reasonable cost, ease of transport, and ease of assembly.  Oh crap, I almost forgot, ability to integrate modern technology.  

The design criteria are now roughly outlined, the question is how to prioritize things, a point value defining which variable makes the most sense is possible, going that far isn't really that rational when I don't have an actual client pain to address, this is more pie in the sky designing, consequently   semi-RANDOM SOLUTIONS with ARBITRARY CONSTRAINTS!  (whoo!)

During the initial "client discussion" I put forth one suggestion, make an inflatable habitat similar to an emergency life-raft.  It met the clients desire for an easily deployed structure that would protect users from the elements, but it did not meet his requirement for a longer term structure.  After several days of thought, I came to the decision that making the Smart Igloo as a singular structure would not make sense, it lacks the flexibility in use that the source inspiration had and making a one size fits all solution just does not feel right.

I envision two primary parts in the final system, a flat pack interior lining that helps keep the insides in and the outside out, the second system, exterior wall and ceiling elements designed to protect the gooey insides of the Smart Igloo.

For the interior, I would start with a vinyl rectangular solid.  (at this point I was planning on putting in a cool rendering, but the relative thickness of the vinyl to width of the Smart Igloo, just didn't work, so descriptions and non-scale MS Paint art ahoy)

The tube of vinyl would start with a thick floor layer, the walls would look something far less crappy than the image below. 

 

The black squares represent cable tie mount points, this would allow for the clients request for adding electrical hardware, data cables, whatever other additions needed by the end user.  (please note the number of cable tie mounts was more visually motivated than an actual system density, that would require an in depth analysis of use cases and cost benefits.)  The blue squares are transparent window holes to allow light to go through.  Said window locations might also be designed for the window panels to be removed and things like ducts for air-conditioning.  The ceiling of the system would look relatively similar, mounting points for wiring and lights.

Now that the interior system is roughly sketched out, to the exterior.  That is relatively easy, sandbags and/or Hesco Bastions (see image to the right), can be stacked on top of eachother to provide thermal mass and insulate the structure.  The real challenge is making the roof of the unit, and I keep flip flopping on how to do that, currently I am leaning towards sandbags designed to help making an arched roof.

Seeing as I have spent too many hours trying to make CAD models look appropriate, finding what the hell Hesco Bastions were called, so onto the real world, thank you for reading.

Sci Fi Weapons

Soon after the big bang the most common compound in the entire universe was Helium Hydride, according to a random science article I read, it is also theoretically one of the most powerful acids known.  Idea for a sci-fi weapon.  A super gun that shoots magnetically contained rounds of helium hydride, to sound even more bad-ass you could say it was in a metallic state.  Example line from a book.

Stellar Wind was screwed, not the usual run of the mill screwed that Planetary Recon dealt with on a new world. this planet had been infected by Inguat, and running down the hallway was one of the largest Inguat Organic Tanks she had seen.  The tank had a unique proactive defensive mechanism that would stop anything with sufficient kinetic/chemical energy.  Fortunately for Wind she had packed four Metalic Helium Hydride rounds, each was capable of melting through almost any compound and was so rare that it was unlikely for the Tank's defenses to be programmed to stop the bullet, so long as it was lobbed softly enough.  Stellar Wind networked with her Ballista and started calibrating the on board magnetic accelerators, too much energy and the Tank's defenses would stop the round no matter what, too little energy and the bolt would be more likely to injure a squad mate.  Within two micro-seconds a range of options were considered.  Steady, aim, fire.  Before her conscious mind could process the sensation of firing Stellar Wind's Ballista let her know that she missed.  Round number two.  Steady, aim, fire. The Ballista releases another wave of electrical energy propelling the 40 mm diameter bolt to several hundred meters per second.  The second round nears its mark, proximity sensors begin to readjust the geometry of the bolt to ensure the acid can take advantage of its metallic state, tearing a tremendous hole into the central mass of the Tank.

(pretty bad eh, I am rather sleepy)
