How much radiation does a luggage scanner deliver vs say medical x-ray?

I saw this posted and was wondering how much radiation this lady was exposed too.

Can someone explain the environmental impact of electric car batteries?

Posted: 16 Feb 2018 12:20 PM PST

Someone was telling me today that electric cars are worse for the environment because of the harm caused in battery manufacture. They said it was equivalent to 30 diesel pickups running twenty four hours a day for some huge number of days. I hope that isn't true.

Thanks.

Edit: Thank you again to everyone. The argument I was in started because I talked about retro fitting an auto with a motor and batteries, and charging with my houses solar system. I was told I would be wasting my time and would only be making a show off statement.

We see headlines all the time about positive results in studies with mice, but what has translated to usable treatments in humans?

Would it be theoretically possible to trap light with a strong enough set of magnets/electromagnets?

Posted: 16 Feb 2018 10:30 AM PST

I have heard of ideas like mirror boxes, but those wouldn't be very efficient, as light would slowly "Degrade(?)" as it loses energy when it bounces. I also know that light is sort of a particle and sort of an electromagnetic wave. Would it be theoretically possible to create a device that could hold light indefinitely by manipulating the light wave? I imagine this would take an unreasonable amount of energy, but black holes do it with gravity. Can you emulate that kind of orbit with a magnet or electromagnet?

Why do we use four or more rotors on drones, but only maximum two on regular helicopters? Why are we not making full size quadrocopters?

Is one more efficient for the size than another? More powerful? "We just alyways did it this way"?

Even if it's not possible naturally, could such a system be engineered?

Is it possible to make concrete a liquid again from a solid?

Posted: 16 Feb 2018 09:25 AM PST

I've seen videos where they un-mix liquids and some other crazy stuff that we never knew was possible, so with that being said would it be possible to make concrete back into the mushy liquidy material it was when it was being poured?
