and if I could figure out the frequency of data transmission

LOL your not trying, Google: frequency finder

But then they could catch on and use a cell phone jammer http://hackedgadgets.com/2007/12/10/cell-phone-jamming/

I was in traffic court this week (normal part of driving for me) and noticed they had a jammer in use (keeps cell phones from ringing during court).

A few super-bright infrared LEDs scattered about a person and suddenly said person looks like a walking supernova to CCD cameras... like so: http://hackedgadgets.com/wp-content/2/_IR_LED_Blocks_Security_Camera.jpg

Yes, but you can't grow nearly everything else needed for you to survive in your back field, either.

Why not? People have for thousands of years, still do.

Of course, that's non sequitur - this particular discussion is about energy independence, let's stay on topic and leave the strawmen in the fields scaring crows.

The point is that in the long run, cheap solar cells will be produced that need very little in the way of resources to make (whether it be skilled labor, materials, or energy).

Self produced ethanol requires even less: Any hillbilly can build and operate a still, the materials are plentiful, abundant, and infinitely renewable, and the energy needed to distill alcohol is provided by the ancient method of burning wood to produce heat.

I do have to concede that the production of the copper materials used in distillation would likely have to be outsourced, but that is of minimal concern.

The fact that China can make a profit (albeit yes with some cheating such as a deflated currency, and no OSHA standards) selling them this cheap means that the resources in them are already down to moderate levels.

... ensuring future dependence on the economies of other nations. Not a positive point when discussing energy independence.

Silicon is pretty darn common an element. The rare earths aren't, but some solar cells types need very little of those.

Hey, man, you figure out how to make solar cells from natural and readily available materials, and I'll be your biggest supporter! Thermoelectric Effect devices (AKA Peltier cooler/heaters) also show promise for both power generation and efficient heating/cooling, might want to check out that technology as well.

Until then, I'm going to go the practical route and stick to my alcohol/electric hybrid idea.

It's a tiny board. the chip is under a blob of goo. The only downside is it has to be a working keyboard so you can use a multimeter to know what pins goes to what key. It's tedious but not terribly hard. Once you know the key matrix you have for the princely sum of 9 dollars a USB dongle that you can wire up how ever you want. You literally have as many inputs as keys.

What I do not know is if it's possible to assign one keyboard to normal tasks and have the hacked keyboard only do some specific thing.

1kW, not 1MW.

I cannot find anywhere where it says kW and not MW. Look at the Youtube video here: http://www.youtube.com/watch?v=RUXXGbNS8oY&feature=player_embedded

Look at this site linked to from TFA: http://hackedgadgets.com/2011/03/07/diy-pulse-laser-gun/

All signs currently point to 1 MW, except to one comment on hackaday. Can you tell me where you got the kW information?

Immersion liquid cooling is something I have done in the past, and that is all well and good, it is after all HOBBY level tech.

For commercial level tech it isn't even a joke, imagine opening the bonnet / hood of your new 2010 car and finding a big tub full of water with the engine immersed in it.

Internal combustion engines have had closed circuit internal liquid cooling circuits for decades, and frankly computers and electronics have had closed circuit internal liquid cooling circuits for decades too.

Think backplane technology and hollow main boards, the liquid coolant flows through the hollow PCB, and mates and either side with the "backplane".

All the advantages of liquid cooling, and almost none of the disadvantages of liquid cooling.

Air cooling has one great advantage, "leaks" don't matter. Provided you have sufficient mass flow you can leak air all over the place.

Older internal combustion engines didn't even have forced circulation in the closed loop liquid coolant systems, they used thermal syphon, much like the space between the racks.

The salient fact here is you have to design in the cooling circuit at the engine block / PCB mechanical design stage, until and unless you do that you are going to be dealing with some god-awful heath-robinson kludge, like fitting an old "stationary engine" (google it) into a 2010 Dodge rolling chassis.

Instead of a 50 buck case containing a 100 buck mobo, you end up with a 100 buck case and a 200 buck mobo for closed circuit air cooling, or a 200 buck case and a 400 buck mobo for closed circuit liquid cooling, and these prices are for large volume manufacture with full economies of scale.

Now go back to your Dodge dealership and take in two 2010 rolling chassis for the annual service, one is running a bog standard cummins, the other is a kludged up stationary engine, and ask the mechanics which one will be more expensive to service.

Closed circuit liquid cooled electronics are not new, it is routinely used in avionics, which of course means that you can back 200 watts of thermal rejection (a modern desktop computer) into a package the size of an iphone, and run it flat out 24/7.

But it costs.

Unless you are in Hong Kong then the cost of land per acre is cheaper, and air is free, and leaks don't matter, and the coolant doesn't cause shorts.

The only other advantage of liquid coolant is it is much quieter, but even so, you can cure that problem by making everything bigger to accommodate much larger passive heatsinks.

http://hackedgadgets.com/wp-content/_hs2.JPG for example, this stuff is extruded and bought by the metre, it doesn't have a failure mode.

Funnily enough someone came out with this little toy. Not exactly a killing machine but not bad. There are several others too.

Portable Railguns are more difficult due to the need for sustained power, but it is fairly trivial to make a charging circuit and use capacitors to provide the field. So, why doesn't someone take this and up its power with a backpack or something into a real killing machines - well something that currently a small explosive charge to accelerate a projectile can do much better.

A keyboard on an exercise bike? Amateurs.

Speed holes are a start. Geek engraving is the way to go.

May I be so bold to suggest that there was no actual "hacking" taking place at all?
By "hacking" I mean the stuff that movies and TV tells us that hacking looks like.
A bespectacled nerd in his teens or early twenties, furiously typing something at his green and black screen filled with lines upon lines of scrolling text, uttering "Come on... come on..." until he suddenly "hacks the Gibson" and a welcome screen appears, upon which he jumps up yelling "YES! I AM INVINCIBLE!".

TFA tells us the following:

Here is the amazing part: With these cashers ready to do their dirty work around the world, the hacker somehow had the ability to lift those limits we all have on our ATM cards. For example, I'm only allowed to take out $500 a day, but the cashers were able to cash once, twice, three times over and over again. When it was all over, they only used 100 cards but they ripped off $9 million.

- known limit - $500
- 100 ATMcards used
- $9 million gone

That comes out to about 90k per card, right?

 
Does anyone remember that little issue with Tranax ATMs from couple of years ago?
It smells to me that something similar happened here. Someone leaving the ADMIN pass at 55555555 or 12345678.
There was probably no need for hacking cards - they probably left the same limit.
Instead, he/she/or it - just changed the codes for banknotes inside the machine.

So... you just tell the ATM that its 100s are 5s - and then repeatedly ask for 5s.
$500 limit coughs up ~$100.000 +/- couple of earlier withdrawals that already left the machine a few 100s short.

In other words - about $90.000 per card.

 
The beauty of it?

Those suspects in the photos may be regular Joes and Janes who came later, found the machine giving 100s for 5s - and got caught on camera.

the hacker somehow had the ability to lift those limits we all have on our ATM cards.

He hacked the Gibson or something...

 
But I would be so bold to say that he might have left the same limit on the card.
Instead, he/she/or it - just changed the codes for banknotes inside the machine. You know.. Like couple of years ago with those Tranaxes...

So... you just tell the ATM that its 100s are 5s - and then repeatedly ask for 5s.
$500 limit coughs up $100.000 +/- couple of actual 5s.

Surely this stuff should be on the idle section of slashdot!

Now, a multi-loaded rocket launcher - THAT could be fun!

Just to bring you up to speed: pacemakers can already be accessed wirelessly, it's much more convenient than a wire sticking out of your chest. And it has already been hacked too.

Well the cellphone as a mouse is already taken care of http://hackedgadgets.com/2006/08/15/nokia-cell-pho ne-mouse/. Now you just need to get a battery compatible with the wireless charging.

It would go beautifully right beside this server farm :)
