@ a fire station..How much longer will this bulb stay illuminated?And even if these bulbs are not as bright as some other types of bulbs.Why don,t citys around the world use this type in 'Some' street lights?so they could save on Energy ? I know they wouldn,t be right for All lights but in historical places it seems like they would be a good idea..Don,t they make this kind anymore?

Since we evolved from the chimps when they started to eat meat and made their brain develop and grow.

Then it seems to me that if we don't eat meat our brains would be deficient.

The system are the train are inside a floating tunnel?
And the second one was the the track of the train are in metal or in magnet it will be under and above it in the middle it is like riding in a rollercoster?

The windmeel was about to be tested to, out in the open sea so if this thing work out there then this can give less fuel use for transportation for many people in the near future?

This are only my theory?
Will it work?

This is kinda funny, but not. I live in the middle of the woods, but there are really not any kind of dangerous animals around here. Today, we got a call that there's a 300 pound black bear running around in our back yard in the middle of the day, which is very strange. Should I go about my business and go where I need to go today or stay in the house and hope he goes away soon? I'd do it tomorrow, but I'm pretty much about to go into labor any day, so my stuff has to get done when I know I have a minute! Yeah, I probably sound stupid, but I'm from a Philly suburb, and this is the first time since I've lived in the woods that this has been an issue. Is there anything you can do to deter a black bear or should I just not take my chances? Just for all the activists, I know I live in the woods, and I am in their habitat and I am NOT complaining that the bear is here. I just don't want to be attacked.

Remember that light is not solid matter; it's energy. This is why it travels at 186,000 miles per SECOND. Besides that, it has no weight. Solid matter has mass and weight. Please give your research along with your answer.

but assumes that medicine stops at......"It is genetic"
