#2385: HoverNet

A fraction of radio waves get transmitted around the globe not by bouncing off satellites but by line-of site transmission between a large number of microwave towers.

These are both costly to build and maintain as well as being so ugly they need to be disguised as synthetic trees.

7216525578_7a52e02871_b

Light travels even faster through the air than through glass fibres and so it would be a good idea, when communicating around the world, somehow to lessen the number of towers…to zero.

Today’s invention is to replace the towers by UAVs carrying small receiver/transmitter dishes.

These have several advantages:

If some need to be switched out of the network eg for maintenance or due to wind damage, the grid they form can be engineered to self-organise in realtime to avoid dropping signal.

The UAVs are much cheaper and less environmentally intrusive than the ridiculous faux firs.

The units could be kept hovering almost perpetually by converting a fraction of the microwave energy they receive into propeller work.

Narrow beam-widths make it harder to intercept the signals and, in any event, the UAVs could constantly move through small amplitudes, randomly, in order to frustrate such attempts.

Although rain fade might be a problem, this could perhaps be lessened by locally increasing the numbers of UAVs when a downpour was predicted.

#2383: Swardrive

Rather than have fleets of noisy grass cutting machines patrolling golf courses, why not build golf carts with integral mowers?

These could be electrically motorised and thus operate quite quietly.

file0001297768610

Every round played would save some money and pollution and the resulting cuttings could be dumped automatically in a pile on the way to the 19th hole.

If a golf club had a wide variety of abilities among its players, then the fairways would be adequately mown over time and the rough too would be greatly improved.

(The greens keeper would still be kept busy, though, with his or her specialist grass cutters).

#2382: Swimonitor

It seems that when children are drowning, they don’t thrash about, but instead they first go silent.

Today’s invention is a life-saving technology which takes advantage of this scary information.

pool-166371-m

Each child entering a body of water would put on a waterproof collar with a throatmike and a small transmitter embedded.

Each child’s signal would be monitored by a system on dry land.

In the event that a given youngster was substantially less noisy than its own average for say 20 seconds, a light on the collar would illuminate, alerting adults in the vicinity.

#2381: MirrorsMaxed

Many people drive around with their car mirrors adjusted wrongly, despite having motorised control over all of them.

This is partly because many drivers use the same car at different times and don’t appreciate that their mirrors can leave large blindspots, when set for a driver of eg different height.

kevin_luu_mirror

Today’s invention is a setup to ensure that the mirrors provide a more complete picture of what’s happening behind.

Instead of sitting still, all three of a car’s rear-view mirrors would scan across their fields of view left and right, as well as slightly up and down.

This scanning motion would itself remind drivers to use their mirrors more than usual.

The movement of the each mirror would allow a bigger visual field to be shown to the driver and the period of oscillation would be quick enough to not miss a fast moving vehicle approaching, yet slow enough to allow events in the periphery to register consciously.

A more advanced version of this system would have a small camera embedded in each to detect which the driver was currently looking in and coordinate the movements of all the mirrors so that when he next looked at say the central mirror, it would be showing as much new infornmation as possible.

#2379: CodeSnap

Imagine a camera which can take shots of code placed on signs or screens at various locations.

The camera processor could undertake text analysis of the image, upgrade itself and run the resulting code.

This would allow one’s camera to take on board the very latest software direct from its environment (eg the television in a store window or browser on screen), including suggestions about the best settings and modes for photography at particular locations and times.

#2376: Ejectube

Today’s invention is a modification to the idea of ejector seats.

The cockpit of an aircraft would run down the spine of the fuselage.

ejectube

When about to eject, this would stand on end as shown, forming a streamlined, blade-like tube containing the separate, pressurised capsules of each crew member.

The tube would be long enough to reach the free stream around a supersonic aircraft, so that ejecting crew members could leave the plane at a much lower speed and suffer far lower acelerations in doing so.

#2375: SpoorSpores

Ever in search of better mousetrap, I’ve been reading about Toxoplasmosis.

This disease is transmissable by about 1% of cats, in the form of parasitic spores, and can be harmful to children and pregnant women, who are not therefore supposed to go anywhere near litter trays.

estock_commonswiki_140858_l

One curious aspect of this bug is that when it is eaten by rodents they lose their fear of predators, making them much easier to catch.

Today’s invention is therefore a ‘green’, rat- or mousetrap in the form of two-layer litter tray. Placed somewhere with a big feline population, the top layer would allow cats to do their business as usual but have a perforated base through which the spore-laden faeces could fall into the lower tray. Then the upper tray would be closed (using a timer like that in a cat feeder).

The lower tray would be essentially a tunnel in which some bait could be placed.

When the smell of cat had abated somewhat, the lower tray could be opened (using the same clockwork mechanism) and large numbers of rodentine pests would then pass through the tunnel, become infected and thus rendered much more vulnerable to the local cats (and dogs).

#2374: Singerprint

According to some headphone and speaker manufacturers, it’s essential to ‘run in’ your new audio equipment by playing a wide range of music through them for perhaps the first few hundred hours.

HiFi buffs tend to be a bit obsessive but this seems crazier than usual. I assume that the aim is to subject the diaphragms to a wide variety of vibrational frequencies, so that the microscopic creases which are formed in their material are not dominated by those of a particular size. A speaker surface with only large creases might be less responsive to very high frequencies.

screen-126311-m

Playing white noise at high volume might ensure an equal distribution of creases across the size spectrum -but if you only ever listen to string quartets, forming creases characteristic of heavy metal might be counterproductive.

Today’s invention is therefore a running-in CD on which is recorded a cocktail of different musical tones, made by instruments of the type that a listener prefers.

This would allow both a much faster running-in period and a personal-preference tuned system.

(Real music enthusiasts would probably have a distinct set of speakers for every different genre in their collection).

#2373: JetTraction

I was watching a lucky fellow at the weekend, driving his Ferrari around town along some cobbled streets.

The tyres were making quite a noise as they fought for grip on the polished, uneven surface.

jettraction

Today’s invention is for ultra high-performance vehicles (including dragsters and motorcycles).

Each wheel is fitted with a hub-mounted set of rocket motors. These are free to maintain their orientation as the wheel itself rotates.

When a burst of intense acceleration is demanded of the engine, so the rockets fire upwards briefly, forcing the tyres into very high-pressure contact with the road surface.

#2372: PassengerPress

Today’s invention is a new way to pack people aboard passenger jets, which might gladden the hearts of the board of Ryanair (if they had any).

This consists of a huge number of vertical boards equipped with a small foldable desk and a display (yellow). These are stationary and fitted with an inflatable mattress on the front side.

standby

An additional set of blue boards can be moved along guiderails and locked in position against a passenger, so that their face protrudes through a porthole which is movable vertically.

These would each have an inflatable mattress too, so that passengers are comfortably sandwiched.

The mattresses could be supplied with a continuous flow of air, the temperature of which would be regulated by the occupant.

This arrangement would allow people to sleep standing up, avoid deep vein thromboses and be much more densely packed than when sitting conventionally.
