Massive solar storm to hit Earth in 2012 with 'force of 100m bombs.What can be the consequence?

We Answered:

Nothing. 100 million hydrogen bombs sounds impressive, but is actually a completely useless media comparison. Hydrogen bombs range from 250 kT to 50 MT, which one do they mean?

And also: 100 million 50 MT bombs or 5 PT TNT equivalent sounds impressive, but isn't a very strong event on the surface of the sun:

The sun produces 3.846 * 10^26 Joule of energy every second on the average. 5 PT TNT is equal to 2.092 * 10^25 Joule. The sun produces over 15 times more energy every single second than 100 million hydrogen bomb can.

Such coronal mass ejections are also no special doomsday event. That is completely stupid. And the predictions of the scientists less impressive when put into the right context: The frequency of ejections depends on the phase of the solar cycle from about one every other day near the solar minimum to 5–6 per day near the solar maximum.

An average coronal mass ejection has a energy of 2 * 10^23 Joule.

The news article is typical sensationalist nonsense, quoting a few scientists out of context.

was this a speed trap camera or warning?

We Answered:

It's not a speed camera. you won't see a ticket. It's just a sign with a radar unit that measures and reports your speed to YOU. It may have software to record the number of speed violations and their speeds but not a specific speeder. The data can be used to justify the positioning of officers to catch speeders. We build one for that purpose a few years ago. It would measure the speed of a vehicle and date and time and record the info. It could not take a picture of the violator - no camera. Many people in residential areas requested this sign be positioned to help slow traffic to normal speeds. So those neighborhoods that had a persistent speeding problem got a cop to catch and issue tickets to specific speeders. Speeding in a neighborhood with kids is not justifiable.

If you are going 56 mph, it probably flashes "Slow Down" but there's no possible way that you could be issued a speeding ticket for 1 mph over the posted limit. No one's speedometer is THAT accurate.
