With almost every country in the world trying to reduce its impact on the environment, the adoption of LED (light emitting diode) lighting has started to become apparent. Programmable traffic signs make use of LED lighting to transfer the work of three or four specific traffic lights into a single programmable display. For example, an intersection (depending on where you live) that makes use of traffic lights has a green, orange and red light for each direction. On top of this they will also have a light to say when you can walk across the crossing and a light that says you can’t. In total that is twenty separate lights. You can quite easily cut that down to eight.
How this works is by having a single light per direction that depicts the color to direct traffic and a single light for each direction that depicts whether or not it is safe to cross for pedestrians. The lights do not have to rely on tinged glass because they are LED lights that can display a color based upon how they are coded. They can also draw symbols and are a lot cheaper to run than a standard light. For a large city that may have thousands of sets of traffic lights this can potentially save millions of dollars in the long term and will dramatically decrease their carbon foot print.
Programmable traffic signs can also be reprogrammed in the event the system needs to be altered. If they decide to suddenly change the color of a stop sign to purple, there is no need to remove the light and replace it; it is just a matter of replacing a few lines of code to depict the color they wish to show. This is essentially a time and cost cutting measure that can be utilized for the long term.
The drug is relatively non-toxic. It is also touted as being effective after the subject has received a dose of radiation. It is fair to suggest that it may help reduce the risks associated with radiotherapy which is often risky due to the potential danger of radiation poisoning. A lot of the time radiotherapy can make the patient exceedingly sick before the patient is able to start recovering from the cancer that radiotherapy is attempting to do battle with. In this regard, PQ can be considered something that will help a lot of people overcome cancer in the long term. Radiotherapy has cost people their lives because the radiation has made them too sick to continue treatment without further risk to the patient’s health.
The buck does not stop there. The battery is touted to last ten years. That is not how long a single charge lasts – but how long the battery itself lasts before it will need to be replaced. This is good news for people who are ecologically minded. A battery can contain all manner of nasty materials that can do some serious damage to the environment. This is likely to be the battery that will finally make electronic cars possible and help reduce our need for (overpriced) petrol. It may also help companies finally start investing in electronic charging stations for vehicles.
