Let me drop a 2 pound drone on your head from just 10 feet above you.

IF you survive it is unlikely you'll make such ignorant statements ever again, and I'm not even talking about loading it up with ordinance or even simply flying into you at high speed.

It's is trivial for a 2 pound drone to kill you by accident, all it takes is the most minimal effort to do it intentionally.

No, it doesn't.

DC is in fact absolutely shitty for long hauls, and that is in fact why we use AC.

Power plants run alternators at specific RPMs intentionally to produce AC. There are no American hydro power generation stations using DC. That would be stupid. Every single one of them uses 3600 hertz multiphase output, one of those phases will give you 60hz AC.

The parasitic losses of DC over long distance is reason enough that it's not done, when you couple in the fact that it HAS TO BE AC in order to do any sort of reasonably efficient voltage conversion just seals the deal.

It's used in SHORT haul international interconnects when each side uses different frequencies for their grid OR when they don't want to stay phase synced.

DC is stupid for normal people for anything other than the last leg, like between your Wallwart and device.

There are three ways to cut down DC voltage: convert to AC and use a transformer, use PWM and large capacitor bank to smooth it back to DC... Or resistive and essentially turn the extra voltage into waste heat. All of those suck, the last most of all, but also the one that can handle large loads best.

There is one way to boost DC voltage. Convert it to AC, or at least half wave AC and use a transformer.

Heh I should have read your whole post before replying to the first line, but let me pick you apart in another one instead.

1. Most stuff just works on high voltage DC as discussed above. Most switching power supplies simply don't know or care about AC or DC and due to their efficiency switching power supplies are used in almost everything electronic.

Absolutely wrong. The first thing most power supplies do is step down from high voltage AC to something in the general range of whats needed on the highest output value. They step down with a transformer. That transformer only works with AC, if you put DC in it, you're just going to burn it up as it turns into a magnet carrying more current (because its not AC, so the there is no inductive resistance, so there is more current). Please don't give anyone advice on electricity. Ever.

2. It's easier (and more efficient) to use high voltage DC for charging the batteries. All you need is a rectifier to convert that 220 into about 250V DC and charge the batteries, which is about as simple and efficient as it comes.

... You do realize those batteries you're referring to are actually made up of a bunch of smaller batteries right? There is no single cell at 200v. You aren't charging one 200v batter, you're charging a handful of 12v batteries that you're just blissfully ignorant of.

3. It's easer (and more efficient) to make an inverter that uses high voltage DC as input. It's pretty easy to just flip the current one way then the other to get AC sufficient to run most induction motors and transformer powered devices.

You have absolutely no idea what you're talking about. The conversion from DC to AC is THE BIGGEST LOSS in the inverters you're referring to. The actual transformer itself is pretty damn efficient if designed properly. Dealing with high voltage DC is extremely dangerous. It ARCs over distances that AC won't. You can put 200v AC traces on a circuit board with little space between them. Do the same thing with the same DC voltage and the board is going to randomly arc all over itself.

4. It's more efficient to use higher voltage in terms of wire size because IxR losses are less for the same power transfer. Chances are the same wires you have now will be fine, but if you go to low voltage (say 13.8V like in your car) you are going to need bigger conductors to avoid the voltage drops over long high current runs. Use higher voltage and lower current, and stick with the wires you have.

The first part is true, larger wires are better for lower current loss. The rest of this is false. DC has different properties than AC. Insulators, wire spacing, and load will behave differently at 200v AC versus DC. You CAN NOT use the same wiring unless you want to burn the building down. Please don't ever tell people anything about electrical wiring, you're going to get someone killed.

The rest of your post is pretty much factually incorrect in everyway as well, but I'm tired of pointing out how little you seem to know about the subject. Again, please stop trying to tell people things like this, its fraking dangerous and people could die from this ignorance.

We need to use HIGH voltage DC at about the same voltage as your house is now, forget about going "low voltage" DC.

No, we don't.

120v AC will kick you off of it if you touch exposed wires.

120v DC will cause you to clamp down if you grab onto a wire or device that electrocutes you, and worse still, it'll kill you at much lower voltages than AC.

On that alone, HVDC is stupid in the home.

Thats ignoring things like how circuit breakers and switches behave under DC verses AC.

AC has a ridiculous number of safety advantages that are not present in DC, which is why you RARELY see high voltage DC.

Couple in the resistive losses of DC and HVDC suddenly looks really stupid to anyone with a clue.

Getting 1500 watts out of 12 volts DC is WAY more dangerous than 1500 watts from 120 AC, by an order of magnitude.
1500w @15v == 100 amps. That means all your in home wiring would need to be ATLEAST 6 gauge wire to be able to carry the current, more likely its going to be 4
gauge wire, and its STILL GOING TO GET HOT.

At just 100 watts, you know, like a high powered light bulb, thats STILL 10 amps, which requires AT LEAST 10 gauge wire ... when most homes are wired with 12 or even 14 gauge!

We're not going to design homes around the Tesla charger and charging our iPhones, we're going to design it around our fridge, microwave, washer and dryer, and air-conditioning.

This entire article is stupid. The conversion losses are nothing compared to the resistive losses from carrying 10 or 100 amps across the wire, even only a 100 feet or so in your home.

I have several 3000 watt devices in my home, which is FILLED with 100 watt light bulbs. In the real world, this shit won't fly.

So they replace the substrate with wood ... instead of silica ... the argument being that wood is plentiful and biodegradable and biologically safe ...

Except ... Silica is more plentiful and more biologically safe since its essentially biologically inert.

As an advantage, silica is NOT biodegradable, because I want my chips to last, not fall apart over the winter when it sheds its leaves.

Silica is NOT the issue for the environment in CPUs, its the production materials and doping agents that are horrible on living things and hard to dispose of.

So congrats ... you solved a problem ... wait, no, you didn't really do anything productive. Not seeing any redeeming quality about a chip produced this way and seeing plenty of down sides.

You keep calling the something, not sure what, a hypervisor, when it is not. I'm not sure if you're referring to the Virtual Memory Manager or Pre-emptive task switching, but neither of those things are a hypervisor, as you've called them in several posts, no version of windows outside of Windows Server has a hypervisor built in. They have had Virtual Memory and Pre-Emptive multitasking in varying incarnations since even before Win 3.0 though, so I really don't get what you think you're talking about. The important thing is that none of this deals with 'virtual hardware' although it may provide APIs through which you can access hardware in an abstracted manner, this is not 'virtual'.

A hypervisor is a virtual machine monitor. It creates 'virtual' hardware by emulation, allowing software under it to believe it is on physical hardware and to generally run unmodified, but without full access to the real physical hardware it is running on. No direct API to the video display, for instance. The software in a hypervisor thinks its talking to physical hardware (or is hypervisor aware, so can detect that it isn't, things like drivers for instance) and has full control of it. Windows has no such feature (other than Windows Server with Hyper-V installed, but thats not really any different than Windows Server with VMware installed). Windows applications talk to a software API, that abstracts the hardware from the software but it does not virtualize it.

Welcome to reality.

Yes, the people who make the laws (you know, the politicians who live in this neighborhood) do get treated differently, thats normal. Not treating them differently would be impossible, and you not understanding that shows a real lack of understanding of how people work.

'Fairness' is an entirely human construct made up by humans to mean treating everyone the same. It does not actually mean treat them fairly.

Nature treats life fairly. The weak die first, the strong carry the species on. I'm sorry that reality doesn't look good for you, but you have to be retarded to be so silly as to think this is ever going to be any other way. Everyone getting the EXACT same privileges will never happen. Not until we're all a bunch of clones who behave and perform the EXACT SAME WAY.

Until then, man who worked harder to get power will get more privileges, just like I expect to get more when I work harder in my job.

Theres not really much wonder to it.

Rand Paul makes his opinion well known and stands by it. Agree or disagree, if you don't know his stance, its only because you've not bothered to pay attention.

Other senators abstain rather than vote against the party, Rand Paul votes. When he doesn't like something, he states it loudly and votes against it. This is unlike people like Changemaster Obama ... who no one bothered to look at his voting record while ranting and raving about him ... at which point they would have noticed, clearly, that Obama made John McCain look angelic. I suspect based on your comment, you don't really look at who you're voting for either, as Rand Paul is rather well known and has stood on his own for years.

Note: I do no vote for Rand Paul, but he is one of the few people that clearly votes based on his own personal agenda, and he does so publicly. I appreciate that. I do not appreciate politicians who claim they support my agenda, when in reality all they care about is more money and power.
