The Tech Section / Science / Space / Re: What makes the Best Electrical Heater?

Geothermal has unadvertized disadvantages. While it's true that ground temperature is often 55 deg F, that is not the same as the amount of latent heat it contains which is used in the heat pump cycle. Geothermal systems work by the geo wells accepting heat during the AC cycle and rejecting it during the heating cycle. In some situations, the ground can become saturated with the heat shed into it during the air conditioning cycle and it then becomes very inefficient at absorbing more heat. External means such as a chiller or heat exchange into a swimming pool can be required to deal with this problem, which reduces the energy efficiency and raises the energy cost.
Various forms of infrared heating devices are available and can be very efficient at heating places that don't get too cold, since rather than heating the air they heat objects illumiinated by the infrared radiation. Commercial food warmers often are of the infrared type, as are heaters in large warehouse type buildings.

Water Cooler / This and that / When can we get our freedom back?

The loss of freedom that largely started on 9/11/01 was principally due to the war on terror. It appears that we may have won that war. Lightning kills more people annually in the US than terrorism.

It's time to back away from the police state mentality that gave us the TSA and concentrate on the real threats to Americans- the bad economy, the greed of the banking class, the future of energy resources, pollution and environmental degradation, and the lawlessness and atrocities engendered by our now misguided war on drugs. The pundit class has their knickers in a twist over the atrocities in Syria, but seem to ignore the truckloads of corpses continually turning up in Mexico. The violence has been spilling over our borders for quite some time, yet we continue to misdirect our resources to the other side of the world.

Water Cooler / Tasteless or Not Tasteless / Re: Cancer

There is also the brief interval between when the photons enter our eyes and we become conscious of the light. In fact we are all only conscious of the immediate past, rather than the present, due to the millisecond lag between sensory acquisition and perception.

Water Cooler / This and that / Batmobile stopped for no tags
« on: March 30, 2012, 02:40:35 AM »

Police in Montgomery County Maryland got a surprise when they pulled over a black Lamborghini with a Batman logo in place of the license plate. Turns out that Batman was driving.
The traffic stop happened in the White Oak area of Silver Spring on Route 29.
Officer Borja says he noticed the not exactly state-approved Batman symbol license plate before he noticed the Caped Crusader himself.
"I walked up and there's Batman, and I said Batman the reason I pulled you over is that you didn't have any tags."
Borja asked for Batman's registration and the Dark Knight had a little trouble finding it, having to get out and walk around to the passenger side of his Lamborghini to locate it.
"I said what is your name. And I was expecting Bruce, and he says Lenny."
Lenny Robinson is his full name, and it turns out he puts on the whole Batman get-up for a very good reason...to try to cheer up kids with cancer at area hospitals.
There is dashcam video of the incident-

The Tech Section / Tech News / Commentary / The NSA's computer system
« on: March 18, 2012, 07:46:40 AM »

Wired has an interesting article concerning the new data center being constructed in Utah.
www.wired.com/threatlevel/2012/03/ff_nsadatacenter/
There are several issues raised such as the NSA’s collection of massive amounts of communications and personal data, the constitutionality of that process, the construction of a new data warehouse and analysis facility in Utah at which the data center will consume 200 megawatts of electricity and require 60,000 tons of cooling, and a computing center in Oak Ridge Tennessee. More interesting is the information concerning the new super computers being built specifically to crack data encryption. There are recent breakthroughs in computing power that at least raise the possibility that AES 256 bit encryption is at risk. Computers that operate at petaflop speed will soon (if not already) be replaced by machines orders of magnitude faster.
“But despite its progress, the agency has not finished building at Oak Ridge, nor is it satisfied with breaking the petaflop barrier. Its next goal is to reach exaflop speed, one quintillion (1018) operations a second, and eventually zettaflop (1021) and yottaflop”
Could computers with this capacity become sentient?
