#493: Wraperr

Half the fun of opening a present is the surprise obtained from removing the wrapping (The web is increasingly populated by videos of people unboxing their brand new x20j-cyberdyne, or whatever, so this must be an important phenomenon).

Today’s invention is intended to heighten that surprise: it is decoy wrapping.

Wrap would be bought two sheets at a time. An outer, translucent one, with reduced transparency and an inner one with a choice of decoy markings. These markings might be eg a well-known chocolate box design, to be used for wrapping anything other than chocolates or a famous book jacket to be used for parcelling-up something other than that particular book.

If you fancied a double bluff, of course, that would be an even bigger surprise for the lucky recipient. For those who like to undertake pre-opening investigations by shaking, this might all be extended by the addition of extra weights within the package and even eg some matchboxes filled with curiously rattling contents.

#492: Windwinders

There’s a lot of well-intentioned baloney going around about how wind energy is going to help save the planet. Well, my money is on nuclear but I’m still keen on using any comparatively cheap sources which may be available.

The trouble is, wind turbines are costly -so much so that to build one big enough to be efficient, it may never be able to pay for itself within its service life. So, today’s invention is to harvest wind energy by a simpler means. Trees.

Trees thrash around if the wind gets up. There are even patents (oh dear) for systems of artificial piezoelectric leaves attached to synthetic trees -a bit like those phone masts which visually shout “Look, not a real tree.”

I suggest attaching to the top of each living arbor a thin wire (It might even make sense to stick on a large, leaflike vane to amplify the natural motion). The wire would run down the trunk and be wrapped around a crude ratchet, nailed to it. This would gradually tension a clockspring which would periodically drive a small dynamo.

Wires from all these devices within a forest would converge on eg a local bank of fuel cells or a branch of the main electrical grid.

#491: Metapistons

Somebody said that every possible innovation, in connection with the internal combustion engine, had been proposed by the 1920s.

Today’s invention tries, nonetheless, to provide more flexible engine performance without entailing a massive amount of extra complexity.

Each piston would contain its own internal piston. This would move axially within it, sealed by a secondary set of rings. The internal piston could be arranged so that on upstrokes or downstrokes it could engage with and lock on to the outer piston. Only the innermost piston would connect to the conrod.

This would provide the possibility of computer-controlled variation in compression ratio (and fuel consumption) whilst the engine was operating. Extra levels of pistons-within-pistons might be engineered to create a much smoother (more nearly reversible) intake and exhaust flow pattern (by gradual, relative movements of these pistons).

#490: Cup coasters

Attending a big meeting recently at a very fancy university event, I noticed that they had provided little tissue pads to site between the cups and saucers. These were, inevitably, branded with the university crest.

It occurred to me that this all seemed a little crazy.

Today’s invention is a generic saucer made of the same pulpy cellulose material from which egg cartons are formed. This would be supplied to institutions together with a small press in the shape of their emblem or logo (just like the ones you get when you register a company in the UK). The cups would still be ceramic.

There would be no more saucer rattling, the drips would be effectively soaked up, the brands would be displayed prominently and the saucers themselves could be easily recycled into eg plant mulch or more saucers, thus cutting down on the dishwashing load significantly. There would also be no toxic ink residues to worry about.

#489: CatTimer

Worried about how to monitor the health of your domestic feline?

Today’s invention consists of a set of electronic scales, wired to a small computer. The scales are set on a chair or stool. On them is placed a cat feeder device (the kind that automatically delivers a cat’s meal at a set time).

The system is capable of detecting when the cat has arrived on the scales -and whether it leapt on gracefully or dragged its way up there.

It can also tell how long it took the cat to eat its food, after the lid opened (ie was the animal hungry or disinterested?) Over time, the cat can have its weight monitored (which might be used automatically to change the amount of food provided or activate an alarm indicating a health problem to the owner).
