Living in Scotland it’s hard to find anywhere offroad to ride one’s motorcycle.

The country is owned by historic estates and many people seem surprisingly ok with being serfs.

Today’s invention is a way to get some offroad hill climbing practice.

A rubble conveyor of the kind used in road maintenance could run either sloping upwards or downwards. In fact, you could have a conveyor loop, since some of these incorporate bends.

Given that these belts can be wider than many country roads, one could ride along the boulder strewn belt without actually going anywhere, even as the angle was being varied.

Imagine a guard dog’s collar and chain.

The collar would have embedded sensors for sweat/temperature and pulse rate.

If the sensors indicated a high level of stress in the animal (as when an intruder appears), the chain could automatically be extended in proportion to the stress it was experiencing.

When you fire eg a pistol, the recoil makes your arm move all over the place (so the next shot can be way off-target).

Instead, the gun user should wear a series of electrical stimulators embedded in a long thin glove on his arm.

As trigger pressure is sensed, the stimulators jab the arm in a pattern across different muscles.

These cause reflexes to fire which get the muscles to exactly counteract the motion of the arm caused by the recoil.

Thus even the first shot can be better targetted but subsequent shots can be improved hugely. This could be adapted for 2 handed weapons.

Since this works by provoking reflexes, any conscious concerns of the gun firer, causing eg tension, are simply overridden (related technology has been developed to lessen spinal pain).

I’ve been inspired by watching ‘Sink The Bismarck’, an ancient movie in which biplanes contribute to the defeat of Nazism.

There aren’t many modern aircraft with this configuration…mostly because adding wings doesn’t work well in high speed flight.

In an application where strength and manoeuvrability are important (such as training) I can see a return to biplanes occurring, especially using modern materials.

Today’s invention is therefore a biplane whose upper wing can be detached in an emergency and which acts as a hang glider -to save the pilot in an emergency. This can be better than a parachute, because it can operate even when deployed at very low altitude.

This might be applied to high-wing monoplanes, but their extra speed might make things more difficult (to say nothing of fitting planes with a single, pilot-removable wing unit).
