IDEA: Safer driving on snow and ice.
Hi,
driving home and being stuck in bad road conditions last night has given me plenty of time to think about improving driving in snow. Of course I am not the first one thinking bout this. Waiting for the truck far ahead to make it up the steep slope (or not as it were) I realized that the other lane with traffic coming the opposite way developped a natural pattern of ridges.
Apparently, the faster counter flow did not just push the snow away from the tires but also compressing it whilst rolling over it. Somehow the "chaotic" compression and displacement resulted in a rough road surface. I would have thought that given this rough pattern (although horribly noisy to drive over) gives more grip both accelerating and breaking -- especially with ASR and ABS as many modern car have now built in.
My idea is therefore: instead of removing the snow/ice create a grip pattern to drive on. Maybe even flash freezing a light coat of water to fortify it. The grip pattern has ice/snow ridges that are slightly elevated and dips accross the tires causing a cobble effect. This prevents both fast driving that is unsuitable for the road conditions and removes the need for creating deep snow walls on either side of the road. It also removes the need for salting.
Drawbacks are the on high frequency routes the ridges will get worn round soon. However, if the ridges would reflect the naturally developing pattern it may become self sustaining. Subject to pressure and temperature this may well be an option.

IDEA: Bluetooth PA system
Hi,
with all the audio visual communications equipment around the house or work, including the mobile equipment, it appears a bit of a challenge to be heard or to interrupt a listener and to get attention.
As most of the equipment is able to synthesize sound it would be a good idea to enable the devices to be interrupted for a broadcast by another system. This would be an opt-in of course to avoid abuse.
Hence, my idea is to enable or attache an enabled bluetooth device for local broadcasts.
Simple ? Too simple ?

REQUEST: mirror replacement+
Hi,
as the follically challenged person I am I find myself turning to odd angles and peek out of the corner of my eye to catch a non frontal view in the mirror. Quite to the amusement of anyone around. And, no, I don't consider myself vain -- although I grudgingly appreciate that you may get the impression.
So I wondered if anyone has started building TV screens to replace mirrors and indeed there are. And indeed there are quite a few. Unfortunately, I couldn't see if any of the devices allow recording and freeze frames. So here is my request to the manufacturers of the world.
Please create a mirror replacement that allows me to record my twirls in front of the flat screen TV and to play them back for review. Of course there are some privacy measures required to prevent the playback by other hands and to avoid the obvious abuse from others to steal the secrets of my expertly eradicating my beard stubbles.
I am sure that its use will extend way beyond the simple bathroom application.

IDEA: furniture lint blocker
Hi,
clearning under furniture is seldom done due to inaccessibility. My idea is to block lint and other items from seeping underneath furniture. This can be achieved in multiple ways of which I shall list a few.
Using positive pressure method - generate a constant airflow blowing out. This works on furniture with very small gaps around. As a fan or air pump is required this is also a costly and perhaps noisy option. However, combined with a heating system may be practical.
An cushion or bellow that can be inflated and topped up if required. This is a fairly universal method but requires a preformed cushion or bellow that fits the gaps perfectly. The filling can be air or some for of expanding foam.
Of course, the obvious way is to use furniture that does not have gaps and smoothly attaches to the floors. This can also be achieved using retrofitted skirting of kind.

IDEA: tamper proof mail self destructive envelope - Method 3
Hi,
this is another continuation of the previous posts "IDEA: tamper proof mail self destructive envelope - Method 1 and ". This method proposes the use of chemical keying a dye in the envelop that will stain the document and make it unusable.
The dye will be situated between two sheets inbetween the outer and inner shell of the envelop and will flow stain the document when the inner shell is broken. Ideally, the inner shell should be decomposing rapidly to allow more stain to enter once it starts flowing. Perhaps an agent with the document will accelerate this.
To disarm the envelop, the dye has a coagulation agent that the receiver can use to solidify the dye and then open the envelope. This coagulation agent should be coded to the individual and as unique as possible. Therefore avoiding another person to open the envelope by accident. In the far future this could even be based on DNA or other biometrical measures.

IDEA: tamper proof mail self destructive envelope - Method 2
Hi,
this is a continuation of the "IDEA: tamper proof mail self destructive envelope - Method 1" post. In the last method, the destruction of the ink was used to ensure the document is destroyed when the envelop was opened without proper authorisation.
Another method is to use special paper, such a photo paper which interacts with the environment when opening the envelop improperly. For example the photo paper will be exposed to normal light when opening an envelope without dark room. However, this mechanism will only protect the content from unintentional opening. Parties familiar with the process can open the envelop in any darkroom and gain access to the content.
A more suitable means would be to key the paper chemically in a unique way -- such as using a photo paper which is save only in a specific wave length using filter paper. A person in a dark room needs to have a particular light source to expose the paper for it not to expose. Therefore the paper can be tuned towards a specific recipient.
The self destructive paper system could be combined with my previous method in a way that the envelope contains a small destructive light source such as LEDs or a flash light that exposes the content upon opening without authorisation.
