#736: Propellets

Having just watched the classic film LeMans again I was reminded of the dangers of carrying petrol around in a vehicle.

Today’s invention is an alternative way to transport petroleum spirit at high speed. Instead of sloshing around in a fuel tank, which, even with foam inserts, is bad for weight distribution/handling, the fuel would be loaded into cylindrical ‘bullets’. Refuelling a car would be a question of dropping a bandolier of such containers into a hatchway.

The bandolier would be engaged with a feed mechanism not unlike that on a machine gun. Pellets of fuel would be sequentially pierced (by a firing pin device) and drained into a small feeder tank. In the event of an accident, these discrete pellets would be very much harder to break open, making an explosive ignition much less likely.

If the vehicle were subject to a serious shunt, accelerometers might be used to detect this and to automatically jettison the remaining bandolier over the crash barrier.

#735: KerbView

Today’s invention is intended to limit the damage I can do to a new set of alloy wheels, when accidentally rasping them along a kerbstone in the course of an ill-fated parking manoeuvre.

Pressing an extra button on the mirror control panel would extend the nearside wing mirror stalk on a vehicle, and deflect it downwards, so as to provide the driver with a clear view of the diminishing gap between wheel and kerb.

#734: DripTrap

Today’s invention is a one-piece, injection moulded drip-tray/coaster. It’s designed so that the circular opening in the top is wider than a cup’s diameter. A simple internal spring is moved aside when a cup or glass is placed in it and subsequently grips the cylindrical body of the cup.

This means that the coaster stays attached to the cup, even when someone is drinking from it. Drips on the sides or bottom of the cup are retained inside the U-shaped inner profile of the coaster.

After drinking, the coaster can be removed and dishwashed with the cup.

#733: SeeGulls

Submarines captured my imagination first when watching Voyage to the Bottom of the Sea and Stingray in the 60s. Today’s subs can circumnavigate the globe, without having to surface, because they have nuclear power plants on board.

Even these high-powered monsters would benefit, however, from not having a giant conning tower sticking out of the deck. This allows the crew to see further when travelling on the surface but adds greatly to the drag when moving underwater and makes the boat highly visible when surfaced.

Today’s invention is a virtual conning tower. The submarine’s hull would be a single, streamlined torpedo shape with minimal protrusions. Instead of a tower, a small flock of UAVs would be released from the casing of the submerged vessel, break the surface and then fly at variable altitude and perhaps at a small distance from the mother ship.

These would be steerable from below, enabling advanced reconnaissance via onboard cameras (submarines can communicate subsea using radio transmissions at around 80Hz). The UAVs could be made effectively undetectable by radar and provide all the benefits, in terms of damage tolerance, of a swarm of aerial robots (at most, these might be seen as a flock of seabirds).

It might even be possible to have a tubular hull shift ballast so as to stand nearly on end in the water -acting as a temporarily high conning tower. This would also allow the diameter of the hull to reduced, cutting drag significantly.

#732: OrdaIN

How to get one’s message across to people who have a rapidly filling email inbox and a reluctance to open messages?

Today’s invention makes a new attempt to introduce some novelty to this endeavour.

Send the person an email entitled ‘Please turn on threading in your email program.’ Then send them a series of sequentially numbered messages, the titles of which form the message you want them to get, -but without their having to open any emails. Irrespective of the receipt order, the email program will place these in the sequence intended by the sender.

Although threading often imposes some kind of indentation on one’s message titles, it might also be possible to ‘draw’ an ASCII-art-like image by creating a roughly-aligned sequence of symbols in titles.

#731: Flashsnap

Having read some articles about law enforcement officials in various countries grabbing cameras from people who may have recorded bad behaviour by the officers concerned, today’s invention is a simple device to help avoid the truth being surpressed.

It consists of an optic fibre cable which runs up the sleeve of the photographer connecting the camera to a flash memory device worn under his/her armpit.

If approached to hand over the camera, it can be quickly detached without drawing attention to the stock of images which were automatically copied there as they were taken.

#730: Snowpage

For somebody who tries never to make hardcopies of anything, I seem to spend a lot of time thinking up ways to improve computer printer performance.

In order to save on the amount of paper that’s wasted, today’s invention is white ink. One’s printer will create a set of human-undetectable marks on every printed page. When that page is returned to the feed tray, it will be identified and the white ink applied, like Tippex, to the pre-existing letterforms (whose precise locations etc will have been stored in printer memory).

This whiting-out could occur in realtime ie with one old letter being ‘snowpaked’ over just before the new one is printed. Thus a single sheet of paper could be reused multiple times -as in a medieval palimpsest.

#729: Titanice

Springing a leak in the hull of a ship is generally a very bad situation; doubly so for a submarine.

Rather than just manning the pumps and stuffing wadding into a breach, today’s invention offers a new approach to the imperative of not sinking.

When some hull perforation is detected or reported, a small submersible is rapidly released from the body of the vessel and automatically driven across the hull to the approximate location of the hole (it could be clamped magnetically to the surface and positioned more accurately using standard subsea lights and cameras).

A powerful refrigeration unit on board this drone sucks in a stream of seawater and blasts out a jet of frozen particles which are directed to the holed area. These build up and form a coarse plug, durable enough to allow more effective repair (and, in the case of a sub, surfacing). Such a system could also operate inside a vessel, given enough space for the required plumbing.

#728: Ward-off

I’ve had more than enough cash extracted from me by Edinburgh City Council traffic wardens. The suggestion is no longer even being made that this funds some useful service or benefits the underprivileged: it just boosts the salaries of the usual crew of bureaucrats.

Today’s invention is a novel application for a handheld camera/printer device. This is intended to undermine punitive unreasonableness in areas where to park my overtaxed car I have to leave a visible paper ticket inside it.

To avoid paying, take a photograph of someone else’s ticket stuck to the inside of their window parked at some distance from your own vehicle (this might benefit from some reflection-reduction image processing). Now print out and place the bogus ticket on one’s dashboard.

No passing warden will be bothered to compare the details of yours with someone else’s.

#727: Securescreen

En route to Stanford University recently, I had to undergo fingerprinting at San Francisco airport, using one of those greasy little touchscreens the customs people use. I’ve been thinking about such screens a lot of late, especially in their role as data fusion tools, uniting information from the modalities of touch and vision.

Touch a part of this cameraphone screen, for example, and it can be made to focus in on that location.

Today’s invention is a touchscreen which unites these functions; providing conditional access to a subset of available applications. Press a particular location on the screen and it determines your identity before allowing you to use the functionality of the ‘button’ you are contacting -or not.
