Look, electric cars are great, and I'm looking forward to the day when I can buy one, but this is BS. First, the power the run the fan is minuscule . On the order of a few Watts. Maybe a few tens of Watts at most. It's an order of magni

Since the false water container on top isn't going to be used anyway, what about just filling it with something hostile to microbes, like dilute hydrogen peroxide? If you wanted to get really fancy, you could even add a couple lines marked

The current pricing for the different size batteries that Tesla offers implies a cost of ~$500 per kWh (the cost differential between the 40 kWh, 60 kWh and 85 kWh packs is $10k). I read "somewhere" (random stranger on the Internet alert)

Compressed natural gas (ie, not liquefied) is the runner-up to purely battery electric vehicles. The problems are short range (go read the reviews of the Honda Civic GX: the range is comparable to the middle battery option in a Tesla Model

While it may be true that jamming a VOR signal is unlikely to cause a crash without other co-incidental bad luck, consider this: The localizer portion of ILS operates on those frequencies, too. I don't think it's all that far-fetched to ima

Depending on the spectrum of the phone camera's flash LED, you might be able to get away with just putting a diffraction grating in front of the camera. I recall, from reading a TI app note about pulse oximeters a while back, that these wo

It does not appear to me that the second gyro is intended to add reliability. Watch how the gyros move in the video: the rotors rotate in opposite directions and the frames twist in opposite directions to apply force to the vehicle chassis

Now granted, I'm still in (probably) the first third of my life, but one thing I've come to realize is that there is too much stuff for me to learn. Even if all I ever did was sit in a room and learn stuff , I would never learn it all.

Valid point. Question: When congress makes infringement a criminal matter, do you think false and fraudulent copyright claims should be treated a criminal matter (since they would be, essentially, false police reports)?

That is an interesting and difficult problem. What if it were framed a little differently, though: Suppose there were a federal licensing tax. You'd pay, say, 5% of licensing revenue to the IRS for the first 20 years, 25% for the next 20

Well, ok, so 30% thermal efficiency at the power station[1], and 10% loss in the transmission lines[2]? That gives us .3 * .9 * 2.5 = .68, or 68% thermal efficiency. That compares favorably to the manufacturer-claimed 62% efficiency of th

Sorry to go off on a tangent, but, >Not to mention that gas heaters are simply more efficient for heating to begin with. Are you sure about that? A heat pump with a COP of, say, 2 is 300% efficient (it is said to have an Energy Factor,

>Fortunately this is counterbalanced by the Oberth effect. Getting to 20% of your orbital velocity requires expending 20% of your rocket's delta-V. And since delta-V is logarithmic in your propellant mass (rocket equation) that could ea

Using the new L2C signal will require a new receiver, but the current L1 (C/A) signal will continue to be broadcast. So you will not need a new receiver to continue the same level of service.

It might be a good idea to read the Wikipedia article on air rights that kordless linked (the GP of your post). IANAL, but it seems like flying an RC plane in the way you describe is just the moving version of a 'spite poll,' which are not

Any pipe to the US would have challenges on the northern end as well. The connection has to connect to something, after all, and the US government could just as easily apply pressure at the point of presence to any backbone provider who

Obviously breaking it into 1000 mini-comcasts, like AT&T, wouldn't, by itself, do anything useful. I think the unstated assumption is that in addition to breaking up Comcast, you'd also break the franchise agreements in order to allo
