Zipping traffic lights

Zipping two car lanes into one create traffic jams (even in Germany where there is a Zipping rule in action). Not waiting for automatic cars, we can help to comb the flow and fasten the narrow places...  (by spacing cars before they need to zip: people prefer to drive to the end making unnecessary stops).

All the components exist: laser cameras, led computer controlled set of lights..

As you may guess the system could be mobile - just unroll the lights before the road work... .

Iron induction adapter

With more available solar energy more and more induction cookers will find the place in the kitchen (they are much more efficient than heating spiral one). One of the problems - cooking only in iron pot. There are some external adapters like this (between the pot and cooker).

My simple idea is to have not external but internal iron adapter. It should have fan like shape to increase the contact surface and create slow spin in liquid. If not mistaken such adaptor would allow to cook in glass pot a bit faster than in iron one (due to larger contact area and convection facilitation). 

The smaller adaprors could be used even for tee 

Update: as always better research show that simple ideas should already be on the market. Accidently found:

The cons of their product buy extra induction heater,  no automatic switch off (probably).   

Soup magnetic stirrer

Looking for an automatic stirrer I found some existing examples:

With them you can't use a lid, they are massive and not easy to wash.  So my proposal is to create something we could see in chemistry -  magnetic stirrer:

Instead of stir bar the stir circle is used to increase the tork and to ease for magnet to reach the bottom place in a soup.
If it creates enough of speed and tork (I think so) sharp blades could make a blender in a pot. If so it would be even better than in my previous idea with a microvawe blender.

Benefits - tiny, easy to wash, stir or blend.  Cons - may not work with iron pot.

Microwave blender

Mixing several kitchen appliances sometimes make sense. For instance with heating blander it is much easier to cook mash soups and for sucklings.   Like this example Zauber ECO-580

But I found it a bit inconvenient to keep such a big extra machine in the kitchen.

So my offer it to use microwaves instead of heating spirals and put the motor to microwave itself:

The plate has a hole where we insert the cogwheel from the blanding container. The second more powerful motor shouldn't enlarge microwave oven too much, besides with some basic CVT (Continuously variable transmission) the second motor could be excluded.
