My recent efforts in consulting and speaking have led to a lot more travel -- which is great sometimes, but also often a drain. I've been staying in so many hotels that I thought it worth enumerating some of the things I think every hotel room should have, and what I often find missing.

Most of these things are fairly inexpensive to do, though a few have higher costs. The cheaper ones I would hope can be just included, I realize some might incur extra charges or a slightly more expensive room, or perhaps they can be offered as a perk to loyalty program members.

Desk space for all occupants

Most rooms usually only have a workspace for one, even if it's a double room. The modern couple both have computers, and both need a place to work, ideally not crammed together. That's also true when two co-workers share a room. And in a perfect room, both desk spaces share the other attributes of a good desk, namely:

• The surface is not glass. I would say more than half the desks in hotel rooms are glass, which don't work well with optical mice. Sure, you put down some papers, but this seems kinda silly.
• Of course, 2 or even 3 power outlets, on the desk or wall above it. Ideally the "universal" kind that accept most of the world's plugs. (Sure, I bring adapters but this is always handy.) Don't make me crawl under the desk to plug things in, have to unplug something else.

To my horror, Marriott has been building some new hotels with no desk space at all. Some person (I would say some idiot) decided that since millennials use fewer laptops and just want to sit on a couch with their tablet, it was better to sacrifice the desk. Those hotels had better have folding desks you can borrow, in fact all hotels could do that to fix the desk space shortage, particularly if rooms are small. Another option would be a leaf that folds down from the wall.

Surfaces/racks for luggage and other things for everybody.

Many rooms are very lacking in table or surface space beyond the desk. Almost every hotel room comes with only one luggage holder, where a couple might find themselves with 3 or in rare case 4 bags. I doubt these folding luggage holders are that expensive, but if you can't put more than one in every room, then watch people as they check in, and note how many bags they have, and have somebody automatically send up some extra holders to their room. At the very least make it easy for them to ask. I mean these things are under $30 quantity one. Get more!

Bathrooms need surface space, too. Too often I've seen sinks with nowhere to put your toiletries and freedom bag. In fact, I want space everywhere to unpack the things I want to access.

Power by the bed (and other places)

Sure, I get that older hotel rooms did not load up with power outlets, and modern ones do. But aside from the desk, most people want power by the bed now, for their phone charger if nothing else. If you just have one plug by the bed, put a 3-way splitter (global plug, of course) on that plug so that people can plug things in without unplugging the light or clock. And ideally up high, so I don't have to crawl behind things to get at it.

A little more controversial is the idea of offering USB charging power. Today, we all carry chargers, but the hope is that if charging becomes commonplace, then like the travel hair dryer people used to carry and no longer do, we might be able to depend on finding a charger. Problem is, charging standards are many and change frequently -- we now have USB regular (useless) and fast-charge, along with Qualcomm quick-charge and USB C. More will come. On top of this, strictly you should not plug your device into a random USB port which might try to take it over. You can get what's called a "USB Condom" to block the data lines, but those might interfere with the negotiation phase of smarter power standards. A wireless "Qi" charging plate could be a useful thing.

As a couple, we have had up to 8 things charging at the same time, when you include phones, cameras, external batteries, headphones, tablets and other devices. So I bring a 5-way USB fast charger and rely on laptops or other chargers to go the distance.

Let me access the HDTV as a monitor, or give me a monitor.

Some rooms block you from any access to the TV. Some have a VGA or HDMI port built into a console on the desk. The latter is great, but usually the TV is mounted in a way that makes it not very useful as a computer monitor for working. It's primarily useful for watching video. I pretty much never watch video in a hotel room, so given the choice, I would put the monitor by the desk, and it should be 1080p or better -- in fact 4K should be the norm for any new installations. If you don't have one, have one I can call down for, even at a modest fee.

I'm doing a lot of flying these days for international speaking and consulting, and I try whenever possible to have 2 or more clients when I fly overseas, since the trips and time-changes can be draining.

In 2010, I proposed the idea of planes with no landing gear which land on robotic platforms. The spring loaded platforms are pulled by cables and so can accelerate and turn with multiple gees, so that almost no matter what the plane does, it can't miss the platform, and it can even hit hard with safety.

After 9/11 there was a lot of talk about how to prevent it, and the best method was to fortify the cockpit door and prevent unauthorized access. Every security system, however, sometimes prevents authorized people from getting access, and the tragic results of that are now clear to the world. This is likely a highly unusual event, and we should not go overboard, but it's still interesting to consider.

(I have an extra reason to take special interest here, I was boarding a flight out of Spain on Tuesday just before the Germanwings flight crashed.)

When Southwest started using tablets for in-flight entertainment, I lauded it. Everybody has been baffled by just how incredibly poor most in-flight video systems are. They tend to be very slow, with poor interfaces and low resolution screens. Even today it's common to face a small widescreen that takes a widescreen film, letterboxes it and then pillarboxes it, with only an option to stretch it and make it look wrong. All this driven by a very large box in somebody's footwell.

One of air travel's great curses is that you have to leave for the airport a long time before your flight. Airlines routinely "recommend" you be there 2 or 3 hours ahead, and airport ride companies often take it to heart and want to pick you up many hours before even short flights. The curse is strongest on short flights, where you can easily spend as much as twice the time getting to the flight as you spend in the air.

Dave Barry once wrote that there is a federal law that no two people on a plane can pay the same price for their seat. Airlines use complex systems to manage ticket prices, constantly changing them based on expected demand and competition, and with over a dozen fare classes with different rules.

In August, I attended the World Science Fiction Convention (WorldCon) in London. I did it while in Coeur D'Alene, Idaho by means of a remote Telepresence Robot(*). The WorldCon is half conference, half party, and I was fully involved -- telepresent there for around 10 hours a day for 3 days, attending sessions, asking questions, going to parties. Back in Idaho I was speaking at a local robotics conference, but I also attended a meeting back at the office using an identical device while I was there.

Recently I tried Facebook/Oculus Rift Crescent Bay prototype. It has more resolution (I will guess 1280 x 1600 per eye or similar) and runs at 90 frames/second. It also has better head tracking, so you can walk around a small space with some realism -- but only a very small space. Still, it was much more impressive than the DK2 and a sign of where things are going. I could still see a faint screen door, they were annoyed that I could see it.

I've been on the road for the last month, and there's more to come. Right now I'm in Amsterdam for a few hours, to be followed by a few events in London, then on to New York for Singularity U's Exponential Finance conference, followed by the opening of our Singularity University Graduate Studies Program for 2014.

I wrote earlier on how we might make it easier to find a lost jet and this included the proposal that the pingers in the black boxes follow a schedule of slowing down their pings to make their batteries last much longer.

Why are there lines at airport security? I mean, we know why the lines form, when passenger load exceeds the capacity, with the bottleneck usually being the X-ray machines. The question is why this imbalance is allowed to happen?

The variable wait at airport security levies a high cost, because passengers must assume it will be long, just in case it is. That means every passenger gets there 15 or more minutes earlier than they would need to, even if there is no wait. Web sites listing wait times can help, but they can change quickly.

We've all learned a lot about what can and can't be done from the tragic story of MH 370, as well as the Air France flight lost over the Atlantic. Of course, nobody expected the real transponders to be disconnected or fail, and so it may be silly to speculate about how to avoid this situation when there already is supposed to be a system that stops aircraft from getting lost. Even so, here are some things to consider:

Southwest recently announced a very different approach to providing in-flight entertainment. Partnering with dish network they will offer live TV and on-demand programming over the in-plane WIFI to people's personal devices. Sadly, for now, it's just Apple devices. I will presume they will extend this to other platforms, including laptops, soon, and they should consider also allowing you to rent a tablet one-way if you don't have your own.

Just returned from an overseas trip to Moscow, I am reminded of the rant I posted earlier about the constant interruptions on the in-flight entertainment system.

Everything I said before remains valid:

Two recent flight booking experiences on United Airlines:

a) I booked a round trip to Toronto with miles. Due to new plans, I ended up getting a different flight to Toronto but wanted to take the same flight back. I had booked return tickets for 2 passengers, but you can book one-way tickets for the same miles price, and you can book passengers together or independently (later joining the reservations to sit together.) It doesn't cost any more to get 4 single legs, it's just a lot more work for you and the airline.

A new paper on trusted traveler programs from RAND Corp goes into some detailed math analysis of various approaches to a trusted traveler program. In such a program, you pre-screen some people, and those who pass go into a trusted line where they receive a lesser security check. The resources saved in the lesser check are applied to give all other passengers a better security check. This was the eventual goal of the failed CLEAR card -- though while it operated it just got you to the front of the line, it didn't reduce your security check.

The analysis shows that with a "spherical horse" there are situations where the TT program could reduce the number of terrorists making it through security with some weapon, though it concludes the benefit is often minor, and sometimes negative. I say spherical horse because they have to idealize the security checks in their model, just declaring that an approach has an X% chance of catching a weapon, and that this chance increases when you spend more money and decreases when you spend less, though it has diminishing returns since you can't get better than 100% no matter what you spend.

The authors know this assumption is risky. Turns out there is a form of security check which does match this model, which is random intense checking. There the percentage of weapons caught is pretty closely tied with the frequency of the random check. The TTs would just get a lower probability of random check. However, very few people seem to be proposing this model. The real approaches you see involve things like the TTs not having to take their shoes off, or somehow bypassing or reducing one of the specific elements of the security process compared to the public. I believe these approaches negate the positive results in the Rand study.

This is important because while the paper puts a focus on whether TT programs can get better security for the same dollar, the reality is I think a big motive for the TT approach is not more security, but placation of the wealthy and the frequent flyer. We all hate security and the TSA, and the airlines want to give better service and even the TSA wants to be hated a bit less. When a grandmother or 10 year old girl gets a security pat down, it is politically bad, even though it is the right security procedure. Letting important passengers get a less intrusive search has value to the airlines and the powerful, and not doing intrusive searches that seem stupid to the public has political value to the TSA as well.

We already have such a program, and it's not just the bypass of the nudatrons (X ray scanners) that has been won by members of congress and airline pilots. It's called private air travel. People with their own planes can board without security at all for them or their guests. They could fly their planes into buildings if they wished, though most are not as big as the airliners from 9/11. Fortunately, the chance that the captains of industry who fly these planes would do this is tiny, so they fly without the TSA. The bypass for pilots seems to make a lot of sense at first blush -- why search a pilot for a weapon she might use to take control of the plane? The reality is that giving a pass to the pilots means the bad guy's problem changes from getting a weapon through the X-ray to creating fake pilot ID. It seems the latter might actually be easier than the former.

I have written before about letting passengers pay for an empty middle seat next to them and recently about ANZ's cuddle class and related programs which partially implement this.

While I believe airlines could sell the empty middle for somewhere in the range of 30-40% of a regular ticket, this still has issues. In particular, are they really going to bump a poor standby passenger who had a cancelled flight and make them stay another night so that people can get a more comfortable seat?

One idea is to allow the sale of empty middles by dutch auction. In effect this would say, "If there are going to be empty middles on this plane, those who bid the most will get to sit next to them." If this can be done, it's a goldmine of extra revenue for the airline. What they sell costs them nothing -- they are just selling the distribution of passengers on the plane. If the plane fills up, however, they sell it all and nobody is charged.

The dutch auction approach would let each passenger make an offer. If there are 5 empty middles, then the 10 people who sit next to them win, but they all pay the 10th highest bid price. If only 9 passengers bid, the 10th highest price is zero, and everybody pays zero -- which is what happens today, except it's semi-random. While this may seem like a loss for the airline, many game theory tests suggest that dutch auctions often bring the best result, as they make both sides happy, and people bid more, knowing they will actually pay the fair price if they win.

(On the other hand, airlines are masters at having two people pay vastly different prices for exactly the same thing and have managed to avoid too much resentment over it.)

There is one huge problem to solve: How do you arrange that matched bidders are sitting together to share the empty middle? Each empty middle benefits two passengers.

Some years ago I made the proposal that airlines sell half of a middle seat at half price or less so that two coach passengers could assure they would have an empty middle next to them.

Like just about everybody, I hate the way travel through airports has become. Airports get slower and bigger and more expensive, and for short-haul flights you can easily spend more time on the ground at airports than you do in the air. Security rules are a large part of the cause, but not all of it.

In this completely rewritten essay, I outline the design on a super-cheap airport with very few buildings, based on a fleet of proto-robocars. I call them proto models because these are cars we know how to build today, which navigate on prepared courses on pavement, in controlled situations and without civilian cars to worry about.

In this robocar airport, which I describe first in a narrative and then in detail, there are no terminal buildings or gates. Each plane just parks on the tarmac and robotic stairs and ramps move up and dock to all its doors. (Catering trucks, fuel trucks and luggage robots also arrive.) The passengers arrive in a perfect boarding order in robocars that dock at the ramps/steps to let them get on the plane through every entrance. Luggage is handled by different robots, and is checked and picked up not in carousels and check-in desks, but at curbs, parking lots, rental car centers and airport hotels.

The change is so dramatic that (even with security issues) people could arrive at airports for flights under 20 minutes before take-off, and get out even faster. Checked luggage would add time, but not much. I also believe you could build a high capacity airport for a tiny fraction of the cost of today's modern multi-billion dollar edifices. I believe the overall experience would also be more pleasant and more productive for all.

This essay is a long one, but I am interested in feedback. What will work here, and what won't? Would you love to fly through this airport or hate it? This is an airport designed not to give you a glorious building in which to wait but to get you through it without waiting most of the time.

The airport gets even better when real robocars, that can drive on the streets to the airport, come on the scene.

Give me your feedback on The Robocar Airport.

Key elements of the design include:
