Stretching a Joke


In the ongoing effort to avoid having to fork out for the sort of fabric used in RIBs I rinse what I've got in a mild solution of PVA and water and leave it out to dry in the sun, as the ancient Greeks probably did.

But I mean, there's got to be more to life?

Deflated


When you're down and troubled and need some loving care, and nothin', nothin' is going right I do what Carole King does and take a folder of my patent specifications down from the shelf.

Whereas Kate Moss never got out of bed for less than ten thousand pounds, these days I cannot get excited about projects that look set to shift less than ten thousand units.

Though I think this one might, despite its dating back nearly twenty-five years. Like the drone at www.teledrone.com though it's been revived by advances in electrical motors, specifically outboards of that type.

For bar none, rigid inflatable boats have blown every other type out of the water in terms of numbers. But like the guy in London who figured carpet cleaning could be better done by sucking instead of blowing, there might be nautical mileage in boats that are deflated instead.

And what else would you do on a Monday morning than give it a whirl? And armed with sheets of stretchable fabric and MDF ~ beside a vacuum ~ I did just that. And you can see the result at https://www.youtube.com/watch?v=LLWW7XThBGU

Remarkable thing is, like many of the best inventions the RIB or rigid inflatable was effectively pioneered by a group of sea scouts and their leader at a school nearest the Bristol Channel. And all they did at the get-go was to add plywood at the bottom of the boat.

The advantage of a deflatable boat however is that it could be flat-packed and ready to deploy in seconds, and cheap as chips: think of it as IKEA on water.

Ultimately whether I advance this or the drone depends on which I see as being the most fun. And as I can sit on it and float gently down a stream like the Leeds and Liverpool canal then this has to be a contender, as life is but a dream. And as it appears from the work of Desmond Hoare (RIB), Christopher Cockerell (hovercraft) and Tony Blair (Iraq), we've a habit of blowing things up and being left deflated...

The test ~ with my trusty Miele on its lowest setting ~ sounded like a descent to the Titanic in a home-built submarine. Watch on full volume, therefore, and be afraid.

Fold


Here's a remarkable fact for you: since the 1970s the rate of company formation in the US has halved and it is broadly an indicator of the economic health of a country.

Nonetheless it remains true ~ since the Industrial Revolution ~ that as often as not the key inventions which underly our prosperity stem from individuals prior to their incorporation.

In the US it is still possible to procure sizeable investment prior to incorporation and I've attracted interest in the recent past to the tune of a half million dollars from an organisation that appears to prefer to review prospects on that basis.

In the UK, in contrast, whilst there is little interest in investing in an individual with an ideas nowadays, there was once in the shape of the 'British Technology Group' that financed the development of an idea of mine back in the 1980s. The evolution of this government initiative stemmed from the amalgamation of the NRDC and the NEB, the former having financed development of the hovercraft: which also sprang from individual experimentation.

What happened to the BTG is instructive, however. Assigned the task of commercial exploitation of inventions from both universities and individuals, it was best known for having backed the development of MRI scanners and monoclonal antibodies, of the sort that we practically depend on nowadays for surviving pandemics, for inst.

Inevitable then that it should have been privatised and like all else stemming from Thatcher's efforts to empower individuals... sold off to a US corporation.

So for those of you mulling the government grant I applied for (and which doubtless because of this blog and the transparency it provides you've yet to reply to)... you're off the hook.

P.S. had to list under aerospace manufacture as nothing related to the production of drones, tho' there would still be a classification for whalebone corset manufacturers.

Death Trap?


In a turbulent world I like to highlight the 'good news' stories, but there aren't any.

Here though an issue of note that touches on the past which is all I have nowadays. No fewer than 180 ex-services personnel are suing the Ministry of Defence for early presentations of various cancers... and winning, despite the MoD refusing to accept liability.

The issue appears to focus on the inhalation of exhaust fumes from helicopters, and looking at the pictures you could understand why: invariably helicopter turbines are situated on the roof, while winch men like the ones pictured in the BBC article were sat all day at the doorway directly underneath.

Many though are ex-pilots, some of whom trained the royal family who were given helicopters to play with, sensibly because this was viewed as the least likely way to die: unless you spend your working life in one. Accordingly there could be a simpler explanation, and that relates to the cabin air drawn from the compressor stages of the engine and used for cabin heating and cooling, beside pressurisation in airliners in particular.

Briefly, the compressor spools go round and round and their bearings are lubricated with oil to keep that happening and when oil overheats (as it likes to do in bearings) then the oil vaporises and chemical additives are ingested eventually into the lungs. 

This was an issue among airline pilots, but you are up against airline manufacturers and oil companies and the revenue they provide their governments... not forgetting the fact that together they get us to the seaside each summer. Failing to investigate such issues is a corporate corruption that we all take part in, therefore, in the way that we're all involved in killing Russians and Palestinians whether we choose to or not.

One reason these campaigns die:

The BA cabin fumes campaign refers to efforts by aviation unions and some crew members to raise awareness and address concerns about potential health risks associated with contaminated air in aircraft cabins. This campaign highlights instances of "fume events" where engine oil fumes, potentially containing toxic compounds, enter the aircraft's ventilation system and contaminate the air breathed by pilots, cabin crew, and passengers.

...is that the people running them keep dying, so that it's a bit like trying to arrange football tournaments from the trenches in WW1: sadly they're likely to be one-offs.

Though many years ago I did attend a small convention at Cranfield, which was like a coach-tour to Lourdes... following lame, wheelchair-bound and confused people into a small hall for a series of personal presentations. Remember the fallout from the Icelandic volcanic ash that shut down trans-Atlantic aviation? Well the captain who flew the Easyjet flight immediately following its engines having had a chemical rinse was sat like 'House' with his stick behind me.

And what struck me too was the number of oil-rig workers: the same services that turbines provide airliner cabins also service the living quarters and all else on North Sea oil-rigs. And indeed I had myself experience of a 'fume event' shortly after the engine start on an old Airbus taxying out at Manchester one night, its tell-tale odour of 'sweaty socks' being unmistakable; albeit most co-pilots wore sweaty socks.

The thing is, children, that when adults get together in groups they're emboldened to act in immoral ways that otherwise guilt and shame would most likely prevent them from pursuing in their individual lives. Yes, we all enjoy watching people die on YouTube over coffee and pastries, but it's not something we actively participate in until we join the airlines, or the Catholic Church.

Funny thing is ~ and I came close from time to time ~ were we to be asked whether we still wanted to fly helicopters if it meant dying sooner, most of us would still say yes the way few teenagers connect flying a fast jet with killing themselves or others, at least at the outset.

Wired


Whilst we enjoy the sunshine here in the UK and people in flip-flops at a place not altogether different from the Nova music festival sing along to chants about killing Jews, some 2000 miles to the East there's a whole different vibe: the optical.

In fact the Ukrainians mark 2025 not so much the year Rod Stewart shuffled onto the stage at Glastonbury, as the year during which warfare changed radically again.

And its war by Deliveroo, Ukrainians making their own napalm from bulk purchases of soap and so forth, and dropping it in lemonade bottles.

Optical drones though sprang from a 'military accelerator' deployed in Russia; which differs from the model here where we ponder by committee for months prior to awarding the grant to BAE Systems after all, because 'nobody ever got sacked for buying IBM'... until now.

In fact the much-vaunted recovery of territory on the eastern border of Ukraine has been reversed almost exclusively by what is effectively fishing twine: optical fibres up to 30km long that preclude the jamming of communications with drones, whilst allowing deaths to be viewed in colour and at a higher resolution. Given life on the sofa here, what's not to like?

The irony is that if you check out the Ali Babas selling these reels ~ relax everyone, I don't need proscribing ~ you would never guess what they were for. Extra long-range fly-fishing aside, however, there's only use for them and it's blowing people up to make money on YouTube.

Which like Alan Partridge I was going to mention in the chat box, but thought better of it.

The off-the-shelf netting that we use here mainly for protection against 'black ops' like golf is a reliable form of protection... will look nice in the Cotswolds, won't it?

Dronehenge


Around the summer solstice I like to mark the event by inviting a few young friends to dance naked on the lawn, and I've asked Prince Andrew to sponsor it.

Hereabouts though was once the largest inland mere in the UK, boggy terrain that almost sank the world's first passenger railway before it had even begun.

I like to think should we be inundated again and the wood preserved in peat, many centuries from now Melvyn Bragg ~ who'd still be alive ~ may host a radio program where archaeologists suggest that this is a site where Colin's ideas went to die.

The pic concludes construction: at left the first to be used for test-rigging the motor and rudder, at right the second for testing on water and at rear the beta-product to test our stock design from the website.

Vee-sectomy


Alternatively to stiffen things up you can foreshorten the prow as I've done here in the OR. First release the ski and then after removing say five inches of length from each of the sides prior, re-fit the hub.
