I would dearly have loved to travel to America on the Hindenburg Hydrogen not withstanding but I fear the cost of the trip would have been well outside of what I could afford.
What would the cost have been in terms of 2014 money and how would it compare with a Concord trip or a Virgin Atlantic third class trip..

During the occupation of the UK by American troops during WWII they were forbidden to drink English milk and had the powered variety shipped in from the USA as English milk was considered too contaminated.

Valves are another case in point when all glass valves were introduced in the fifties we had three decades of TV,s that had to be banged on top to make them work due to corrosion on the valve pins, the only ones that were reliable were the Russian ones that had gold plated pins.
If I compare the cable and connectors that connect the monitor to the computer with the cable and connectors that connect the motherboard to the drives the comparison is ludicrous yet a monitor connection coming loose will only cause a moments annoyance while a loose HDD cable can result in hours of work to undo the damage.

Seventy years ago when I was making my living fixing radios one of the chief sources of annoyance was faulty valve sockets that were laborious to replace and good quality ones were difficult to obtain so one often resorted to soldering the valves in !.
In the present hi tech world where semiconductors and valves are reputed to last up to 50 years and disk drives to run 50,000 hours between failures connectors seem to get poorer and poorer , I have just spent about a day sorting out disk drives that got corrupted by loose connections.
Far be it for me to recommend this form of treatment but this article may be of interest.
The piston type internal combustion engine has had at least 130 years of development with the recent introduction of electronic control, Turbocharging and the re-introduction of variable valve timing I do not think any revolutionary developments have been missed.
Every few years a radical new design is proposed but apart from the opposed piston layout and the Wankel few if any have got into production

The Wiki article on magnetar,s gives all the answers, for a typical field of 10^10 T the energy density is 4*10^25 J/M^3 , converting with e=mc^2 gives a density 10^4 times that of lead.

In a recent discussion of gravity and magnetism it was noted that a magnetic field stores energy that has a mass equivalent.
I am weak on units but would like to know how much energy is stored per M^3 in a 1T field and whether in the intense field around a magnastar the mass equivalent of the energy could approach that of water 1000kg/m^3
Some forms of virus affect the behaviour of the infected creatures such as those that cause mice to be attracted to cats so that they can be eaten ! or those that cause ants to climb up stalks.
The sound of running water seems to promote the urge to pee. Is this caused by a virus wanting to get into the stream to spread ?

The zeroth commandment to mankind was "go forth and be fruitful" and is the only one to which much attention is paid.

It is my experience that work in new technologies tends to be well paid for about ten years then fizzles out , I worked with the early crude monochrome and colour TVs which needed a lot of skilled maintenance now they are considered throw away items when worn.
I also worked with scanners both large and small for the print industry but now they have been killed off by digital cameras.

If you want a really high flashing rate you could use a laser or any other source of polarised light and a Kerr cell.
These were used in pre war projection TVs and the early HELL film recorders with which I used to work.

During WWII the signals used by the Luftwaffe to guide their bombers was interfered with so that they bombed the wrong target
Cordless chargers are very useful for implanted devices such as pacemakers and cochlea implants but generally speaking a wired connection will always work better if practicable.
I believe some use has been made of charging coils for busses at bus stops but they are a rather special case.
some nuclear "waste" contains valuable elements such as Polonium our uranium 294 but the cost of extraction is very high and would not justify extracting elements such as Radium or trying to use the heat generated by the waste en mass to generate electricity.
