Well, really it matters little to me about the optical drive. In the last year I have used an optical drive once to read the CD which contains the service manual to my garden tractor...in PDF format...if I consult this manual more frequently I may just have to put the file on the laptop.
I learn to sleep through it. My wife is on call very nearly 24-7 and gets called multiple times every night.
Her phone vibrates, then does a loud alarm, sorta like a Hollywood submarine dive alarm. The vibrating phone on the nightstand usually wakes her, but not always. She reacts to her phone immediately, but not to other noises. If I need to wake her up for some reason it is easier to call her phone, then get her attention.
The key is you need to pick an alarm that you will respond to immediately, but your partner will tend to ignore. Then have the alarm become something that will wake the dead so your partner can kick you out of bed.
I see slightly into the infra-red end of the spectrum, and proved it repeatedly in film photography class. When we were rolling negatives for small batch developing in full darkness I could see my classmates, and if they dropped something I could pick it up and take their hand and put the whatever in their hand.
The downside is my resolution in IR requires total darkness, and is very very faint. I didn't believe that I was doing it until I had several experiences with it and some conversations with classmates. I have met another person who also reports a similar experience, so I have to believe it is not terribly uncommon, just uncommon to recognize and not all that useful for most people. I would be unaware of this ability if I never took film photography.
Because your experiences in the UV end of the spectrum are obvious enough during full light I expect that projecting a large rainbow from a prism on a wall and having several people mark the lowest and highest portions of the spectrum will give you results you will find useful. Have them also mark individual color bands and you can calibrate the setup to other people in a repeatable manner.

My wife loves her Kindle. She uses it a whole lot, and the battery life is incredible and nearly what is advertised (30 days!). I would like one too, but I want color E-ink. I know, it only matters with maybe one of 10 documents I read. (especially considering that I reference out-of-print scans from Google books rather frequently)
Failing color E-ink, I probably will not get a Kindle.
I have 4 acres with trees, and get sick of mowing. (I also have a 1 acre woodlot) I see that the solution given is flawed for several reasons. In the real world it will produce a poor looking finish, but that is tolerable. The lawn will be one height and neat, but not well finished. Also the mowing modeled as a circular area is a built in inefficiency, because only the edge of the circle is cutting.
I did not get out of the setup whether edges were treated as "hard" or "soft". A hard edge you cannot pass the mower over, this would be a wall, tree, mailbox, or valuable planting. A soft edge would be a material that you can pas the mower over, this would be a driveway, patio, and certain planting bed edges.
I find that the best balance in real world finish and speed is when I mow 2 laps around the edges so I can turn with my old school garden tractor, then to create boxes that move across the yard. This allows for maximum velocity to be maintained, long orderly cuts which provide better finished appearance than irregular turnings, and adequate turning radius for my equipment, which is very different from the OP's.
Since my machine has a top mowing speed of about 5mph, and a 46 inch cut, this takes just under 1 hour per acre, for me. About 3 hours for 4 acres on a good day mowing neat growth. If my meadow has sat for several weeks, it will take 3 hours to mow and mulch that area alone, a common problem in the spring since it is river floodplain and will be under water a fair number of times.
With a zero turn cutting a 60 inch path at up to 9.5mph going in straight lines will outweigh minimizing recut because slowing down to turn reduces the area cut per unit time more significantly than cutting a small area a second or third time. That is a muscle car of a lawnmower the OP is using. He should take a whole lot less time to mow than he reports, probably because of all the turns he is taking.
This is trying to cover medical and time off work, plus a little, in an effort to prevent a repeat of the McDonald's coffee debacle. The man can prove that he was injured, and the jar contributed to his injuries. Del Monte and Kroger are just trying to prevent a PR nightmare with a relatively small (for the companies involved) sum of cash.

Kinda sad to see the end. Digital is so easy and high quality it is not unexpected. I am sure small batch processing will still be available, but that means you need equipment, chemicals and the knowledge how to use it.
Has to be induction. You can build half a transformer (coil of wire) and get a measurable voltage, and almost usable current from standing under a high tension wire. No trespassing involved.
Now getting the device in place, doing surveillance, and getting the device removed before it is noticed would be a challenge.
The blades which are linked to the wheels turn to drive the car, but actually travel at about 90 degrees to the cars travel, so the blades are traveling in a direction of efficiency once it is at speed for a sail relative to true wind.
I still fail to see any practical real life value for this.
Iceboats hare typically clocked in the 50mph+ range, with wind as low as 5 mph, though more typically 10 mph wind. The wing shape of the sail and the angle of apparent wind make the vessel move faster downwind by tacking than going in a straight line.
There is a control box on the wall in the basement attached to the breaker panel in my case. An electrician checks it every few years. I have never had a brown out since living here, this system was in place before I bought.
Opting out would be installing propane and a propane hot water tank(not likely to happen), or installing geothermal hvac with a geothermal hot water tank (costs about the same as a propane system _and_ propane service) or installing point of service hot water water heaters (also not happening).
They got this on my hot water....and I can't opt out or over ride. They report only using it for about an hour at a time, and only 2 or 3 days a year for the last few years though. Yes, peak demand during summer afternoons.
This is a novel application of existing ideas. Some of this technology is in use on diesel engines (compression ignition, direct injection, timing direct injection to time ignition) and heat regeneration is in use in all power plants, and some major industrial processes, a lot of ovens and forges use exhaust to preheat combustion air and fuel.
Heat regeneration is already used in cars through exhaust gas recirculation (EGR) technologies.
One of the larger losses in an engine is "pumping" or simply moving air through the engine for combustion, and exhaust out of the engine. In the article they call it "throttling losses"
The catalyst can be as simple as a coating on the injector nozzle as it enters the chamber, partial oxidizing does sound dodgy though.
They are also comparing to a rather small vehicle, the Prius, so I think their numbers are plausible, not too sure about this going mainstream at this kind of efficiency though. Automakers and oil companies will likely screw up the implementation, and lawmakers will regulate inefficiencies into existence, and the system will have to be proven safe and not a bomb on wheels, especially in the case of accidents.
Set a clock based on the moons of Jupiter. Portions of America (not just the US) were originally surveyed using a clock set using look up tables and Jupiter's moons, and then a sextant sighting noon to accurately obtain longitude.
For one case there was a device invented by a woman I know to aid in moving patients about in a hospital bed. It improves patient safety and staff safety. She was told that because she patented it, the companies would wait out her patent even though she was not seeking significant money for the idea. Profit for her would have been having a safer job.
Publishing would have been better, establishing prior art is sometimes more important since it encourages competition. Patenting however protects an idea that you are able to implement and use, reducing competition for a period of time.
Most earth movers only use about 50 horsepower or less. (Think about stuff you see in the city or on a farm.) Most small cars have much more than that. A lightweight sports car will boast 300 horsepower.
The older architecture is quite capable of moving mountains especially since there is a lot of existing software that is already available. Using the latest technology for a complete computer on a single chip only makes sense for the manufacturing processes, not the logic.
I still use my Pentium Pro machine. It is able to perform nicely at non-gaming tasks, well other than nethack, and most web surfing.
Cheap, reliable computing is more important than powerful computing for many applications.
220 to 110 is not a transformer operation. It is using two legs of 3-phase AC and a ground instead of one leg, a neutral, and a ground(grounds are electrically optional, safety required).
Anytime you convert energy from one state to another using a larger device to power many smaller devices you have the ability to realize net energy savings. This is why electric cars, charged off the grid, are better than just relocating the pollution to a centralized site. Similarly using a train or a cargo ship is better for long haul transportation than using semi-trucks. Larger aircraft typically move more people/cargo for a given amount of fuel (assuming full utilization)
Using a large DC converter in an adjacent space with copious forced air cooling and proper AC for your servers will probably be the best of both worlds. Short electric run and better utilization of existing cooling capacity.
