This is how to get really efficient computing.
There was a Russian book I found on systolic computing. Brilliant stuff, really inspirational for me. It's applications in video and image processing were immediately obvious.

Mathieu] was interested in using more solar cells for his everday electronics. He looked around but couldn’t find much information about using pholovoltaic for small indoor devices. We remember hearing some of the same things from [Dave Jones] in one of his EEVblog installments from a few years ago which looked at solar calculators; the only indoor solar gadget we can think of.

Subject: Fwd: Home Performance Nightmare
Home Performance NightmareGreetings Planetsavers
Tonight we're diving in to fixing the worst Home Performance nightmare I've ever seen. That's right, it's the house I just bought in Virginia! Over the last few weeks I've shown you some pictures but today I took my first blower door reading... 7800 cfm50... and it never even got to 50! Actually it got to 34 with an open fan. We'll talk about what that all means and what can be done about it... on this house that the DOE wants real tight.
BTW I met some neighbors and they told me that the home had over $1,000 electric bills. We mentioned the insulation disaster a few weeks ago (shown above) but now we know how big a disaster that was.
This is actually a case where the Home Performance Failure actually cost the owner his home as the Utility Bill certainly contributed to them losing it in foreclosure!
Check in at 6 pacific and we'll take on this challenge. Hint: greater measures will be required than we discussed last week. Also I've already implemented some of last weeks suggestions from the audience. I'm getting excited about this one.
See you tonight,

If your running active pages for every web hit in stead of static pages with client scripts, then your consuming 10x or more the CPU power needed then the alternate software approach. With this you will then required 10x the computing resources. But this is only have of the iceberg. For every Watt consumed a Watt is lost in the power supply. For every Watt spent in the computer box, an additional Watt is spent cooling those systems.
So a 100 Watt CPU at full tilt load (which is where you want to run it for highest power efficiency, although consumption is also at it's peak) you spend 100 watts in the power supply and fans etc and another 200 watts on the air conditioner.
Now the argument to use scripted languages and these higher level coding languages is to cut the development time and cost down. This come at the price of higher cost in servers, application management and power consumption. These are a perpetual part of a companies burn rate and ultimately become a limiting factor for some companies.
Cooling is 1/2 the cost of running a data center, if your power source gave you that for free basically then you will save money.
I am posting this link because it's insightful. This gives you some idea why Bloom Energy is valuable, since Microturbines are a direct competitor for micropower generation systems.

So let me explain how this works.
We recently had a Green Technology Bubble. It was getting hyped in the press and everyone thought it was where things were heading. Or so it seemed. It's been several times now in my life I've watched everyone jump on to the Solar/Green bandwagon only to have the wheels fall off and everyone abandons it in a hurry.
There were and still are a number of good technologies and companies, but it's just not happening.
There are several factors, Solyndra and Enron being a large part of this.
See with a bubble comes a flood of VC and Speculator money. As it is with any Gold rush, there are also no shortage of con-artists and scammers, plying there trade, and you also have many clueless idiots that just show up to the party hoping to figure it out and get in the game.
The amount of financing is finite and will only go so far till there are some successes and failures before more arrives. Who get's the money from VC, Federal and State Grants, private investors? Usually not the engineers and scientists who lack the slick marketing skills of Madison avenue. It's people who already have money, or their kids just graduated from some top university. Those are usually first in line.
Now the easiest way to ensure a Green Technology bubble crashes and burns is to load the deck where all the really big big Mind boggling big funded start-up are run by people who have no intention of ever seeing Solar technology ever see the light of day. And you take everyone's money and run it in to the ground at full speed. This will burn every investors and make it nearly impossible for every little inventor with the real stuff from getting anywhere.
Meanwhile you have the California state government saying they are for solar then sabotage and strangle in bureaucratic red tape every solar plant and come just shy of outlawing solar panels on people root tops.
Now that they have killed this bubble and scared off any investment opportunity, you have then using the Solyndra to taint other companies that have nothing to do with it.
See the article Below. Bloom Energy isn't even Green energy. Fuel Cells could be but the ones they are equating with Solyndra are using Methane Natural Gas, a Hydrocarbon fossil fuel.
The Bloom energy devices are only somewhat less polluting, but make a lot of sense from a technology point of view as if the electrical grid fails the City Gas lines would most likely be working (as least outside of earthquake country). They provide a clean, lower maintenance version of a Back Up Generator for Data Centers, and little more.
Washington Times: NICHOLS & DRIESSEN: Delaware’s very own Solyndra?
From an E-mail from cfact.org
CFACT senior policy advisor Paul Driessen and independent financial consultant John Nichols called attention to an attempt by California-based Bloom Energy to get the State of Delaware to subsidize the manufacture of supersized fuel cells and to replace natural gas and coal-fired power plants for electricity generation (.Delaware.s very own Solyndra," Washington Times, 9-23-11).

"The Google funded Enhanced Geothermal Systems research at the Southern Methodist University has produced a coast-to-coast geothermal potential map of the United States. Having invested over $10 million on geothermal energy, Google seems to believe that it is our best bet at kicking the oil habit (especially now that nuclear power has suddenly become disproportionately unpopular)."
