Immigrant Innovators (June Kronholz - Wall Street Jounal)

Immigrant Innovators

Start-up engineering and technology companies that had at least one immigrant founder produced $52 billion sales in 2005 and employed about 450,000 workers, according to a study by researchers at the University of California at Berkeley and Duke University.

The study surveyed 28,776 engineering and technology firms that were started between 1995 and 2005, and found that one-quarter had either a chief executive or a chief technology officer who is an immigrant. Of those, one-quarter had Indian-born founders. The biggest share of the start-ups is in California, where almost 40% of new engineering and technology companies have immigrant founders.

The study also found that 24% of international patent applications by U.S.-based inventors were filed by noncitizens. That’s up from 1998, when 7% of patent applications had a foreign inventor or co-inventor. The Berkeley and Duke authors said they reached that conclusion by analyzing World Intellectual Property Organization records for international patent filings by U.S.-resident inventors.

Supporters of an immigration bill are likely to use the study to argue the importance of foreign-born workers to the U.S. economy. An immigration bill passed by the last Congress and heavily lobbied by business groups would have greatly increased the number of green cards available to skilled workers. Business has long argued that the U.S. schools aren’t turning out enough scientists, mathematicians and engineers, and that the economy will lose its competitive edge without more skilled foreign workers.

But the effort to allow in more skilled legal workers was overwhelmed by questions about illegal immigration, and that’s not likely to change when the new Congress takes up immigration. Some business supporters would like to see a separate skilled-immigrant bill pass quickly before the current shortage of employment-based visas puts a crimp in the economy. But most immigration groups oppose that approach, fearing that support for a bill to also help unskilled legal immigrants and the estimated 11.5 million illegal immigrants would fade if skilled workers are taken care of first.

My 2 cents on the HDTV Dillema

As part of the Christmas celebrations my wife and I decided we are going to spoil ourselves by buying an HDTV. Little did I know the great dillema that lay ahead of us. Should we buy a plasma or lcd? Do we need 1080i or 1080p? Does the native resolution really matter? Do we care whether there are 2 or 3 HDMI inputs? Do we need optical outputs? What brand do we go for? After a month of painstaking research we finally bought a TV and I thought I would share my thoughts with all of you. Read on...

PLASMA Vs LCD
When thinking about buying an HDTV, the first decision you need to make is the technology you plan to go with. Right now there are two main competing technologies namely PLASMA and LCD.
I am going to start by listing a number of important differences between the two:

1.Contrast/Black Levels: Plasma technology has certainly achieved quite high contrast ratios, a measure of the blackest black compared to the whitest white. You can find Plasma tv's that boast contrast ratios of 10000:1. LCD TV's use the most power when displaying a very dark or black image. This is a difficult process, and despite recent improvements in LCD black levels the contrast rations are not as high as their plasma competitors. Some of the Sonys, Samsungs and Sharps boast a contrast ratio between 5000:1 and 8000:1 which is teriffic. Hoever Contrast ratio is one category in which Plasmas still outperform the LCD's.

2. Color Accuracy: Plasma color richness will prevail in rooms with low lighting levels. However in a resonably bright room, Plasmas have a lot of glare which personally I have an issue with. LCDs perform a lot better in a well lit room because of the inherent anti glare technology and brightness.

3. Viewing Angles: A year back this would be a clear win for Plasma TV's since LCD TV's offered viewing angles in the 120-130 degree range. However now most LCD's offer a 178 degree which is on par with Plasma TV's

4. Computer Use: Clear win for LCD's. LCD's display static images from a computer or VGA sources extremely well., with full color, no flicker and no screen burn-in. Another important advantage for LCD's is the native resolution which can be as high as 1920x1080 currently. Plasma's typically offer anywhere between 1024x768 and 1366x768. LCD TV's provide a higher resolution for the same price as compared to a Plasma.

5. Screen burn-in and Longevity: LCD technology is not prone to screen burn-in. With plasma, static images will begin to burn-in or permanently etch the color being displayed into the glass display element. LCD's also get the edge on longevity. LCD's last as long as its backlight does. Plasma, on the other hand, utilizes slight electric currents to excite a combination of noble gases (i.e., argon, neon, xenon), which glow red, blue, and/or green. This is an essentially active phenomenon, so the phosphoric elements in plasma displays fade over time. Many manufacturers state a new half life of 60,000 hours.

OTHER CONSIDERATIONS
1. Inputs and Outputs: The main input that you should be concerned about when buying an HD TV are the Hight Definition Multimedia Interface (HDMI) inputs which is an all-digital audio/video interface capable of transmitting uncompressed streams. This is the best interface to use when connecting your cable box/DVD player to your TV and supports the highest resolutions. Ideally the TV you decide to buy should have at least 2 HDMI inputs which allows connectivity from the cable box and also your DVD player/Gaming Console. If you an audiophile and care about lossless audio, you should consider getting a TV with an optical output. Most of the other inputs and outputs are pretty standard on most TV's.

2. 1080i or 1080p: The highest resolution currently supported by HDTV's is 1080p (progressive) or "True HD". An important thing to keep in mind is there is no TV programming currently available at 1080p (Highest supported is 1080i). However if you have an HD DVD player or a blue ray disc player or an XBOX 360/PS3, it makes sense to buy a TV with 1080p capability as these devices produce pictures at 1080p. Keep in mind that there is a price difference of about $500 to go from 1080i to 1080p.

3. Brand Selection: My personal preference within the LCD market is the Sony Bravia V series or the XBR. I also like the Samsungs a lot. I have also heard good things about the Sharp Aquos line. In the plasma market, the best choice by far is Panasonic. They make some amazing TVs. I should reiterate that these are just my personal views.

4. Extended Service Warranty: I would strongly recommend that anyone buying a TV worth so much money would be dumb not to get the extended service agreement. Most TV's come with a standard 1 yr warranty. However you have the ability to extend this to anywhere between 3-5 yrs for about 20% of the cost typically. It would be prudent to go with this especially since this is a display technology.

So that about sums it up. I hope this is helpful in making your decision. Feel free to email me at gkuruvilla@gmail.com for more info.

The Logical Song

When I was young, it seemed that life was so wonderful,
A miracle, oh it was beautiful, magical.
And all the birds in the trees, well theyd be singing so happily,
Joyfully, playfully watching me.
But then they send me away to teach me how to be sensible,
Logical, responsible, practical.
And they showed me a world where I could be so dependable,
Clinical, intellectual, cynical.

There are times when all the worlds asleep,
The questions run too deep
For such a simple man.
Wont you please, please tell me what weve learned
I know it sounds absurd
But please tell me who I am.

Now watch what you say or theyll be calling you a radical,
Liberal, fanatical, criminal.
Wont you sign up your name, wed like to feel youre
Acceptable, respecable, presentable, a vegtable!

At night, when all the worlds asleep,
The questions run so deep
For such a simple man.
Wont you please, please tell me what weve learned
I know it sounds absurd
But please tell me who I am.

Florida County generates electricity from Garbage

FORT PIERCE, Fla. (AP) — A Florida county has grand plans to ditch its dump, generate electricity and help build roads — all by vaporizing garbage at temperatures hotter than the sun.

The $425 million facility expected to be built in St. Lucie County will use lightning-like plasma arcs to turn trash into gas and rock-like material. It will be the first such plant in the nation operating on such a massive scale and the largest in the world.

Supporters say the process is cleaner than traditional trash incineration, though skeptics question whether the technology can meet the lofty expectations.

The 100,000-square-foot plant, slated to be operational in two years, is expected to vaporize 3,000 tons of garbage a day. County officials estimate their entire landfill — 4.3 million tons of trash collected since 1978 — will be gone in 18 years.

No byproduct will go unused, according to Geoplasma, the Atlanta-based company building and paying for the plant.

Synthetic, combustible gas produced in the process will be used to run turbines to create about 120 megawatts of electricity that will be sold back to the grid. The facility will operate on about a third of the power it generates, free from outside electricity.

About 80,000 pounds of steam per day will be sold to a neighboring Tropicana Products Inc. facility to power the juice plant's turbines.

Sludge from the county's wastewater treatment plant will be vaporized, and a material created from melted organic matter — up to 600 tons a day — will be hardened into slag, and sold for use in road and construction projects.

"This is sustainability in its truest and finest form," said Hilburn Hillestad, president of Geoplasma, a subsidiary of Jacoby Development Inc.

For years, some waste-management facilities have been converting methane — created by rotting trash in landfills — to power. Others also burn trash to produce electricity.

But experts say population growth will limit space available for future landfills.

"We've only got the size of the planet," said Richard Tedder, program administrator for the Florida Department of Environmental Protection's solid waste division. "Because of all of the pressures of development, people don't want landfills. It's going to be harder and harder to site new landfills, and it's going to be harder for existing landfills to continue to expand."

The plasma-arc gasification facility in St. Lucie County, on central Florida's Atlantic Coast, aims to solve that problem by eliminating the need for a landfill. Only two similar facilities are operating in the world — both in Japan — but are gasifying garbage on a much smaller scale.

Up to eight plasma arc-equipped cupolas will vaporize trash year-round, non-stop. Garbage will be brought in on conveyor belts and dumped into the cylindrical cupolas where it falls into a zone of heat more than 10,000 degrees Fahrenheit.

"We didn't want to do it like everybody else," said Leo Cordeiro, the county's solid waste director. "We knew there were better ways."

No emissions are released during the closed-loop gasification, Geoplasma says. The only emissions will come from the synthetic gas-powered turbines that create electricity. Even that will be cleaner than burning coal or natural gas, experts say.

Few other toxins will be generated, if any at all, Geoplasma says.

But critics disagree.

"We've found projects similar to this being misrepresented all over the country," said Monica Wilson of the Global Alliance for Incinerator Alternatives.

Wilson said there aren't enough studies yet to prove the company's claims that emissions will likely be less than from a standard natural-gas power plant.

She also said other companies have tried to produce such results and failed. She cited two similar facilities run by different companies in Australia and Germany that closed after failing to meet emissions standards.

"I think this is the time for the residents of this county to start asking some tough questions," Wilson said.

Bruce Parker, president and CEO of the Washington, D.C.-based National Solid Wastes Management Association, scoffs at the notion that plasma technology will eliminate the need for landfills.

"We do know that plasma arc is a legitimate technology, but let's see first how this thing works for St. Lucie County," Parker said. "It's too soon for people to make wild claims that we won't need landfills."

Louis Circeo, director of Georgia Tech's plasma research division, said that as energy prices soar and landfill fees increase, plasma-arc technology will become more affordable.

"Municipal solid waste is perhaps the largest renewable energy resource that is available to us," Circeo said, adding that the process "could not only solve the garbage and landfill problems in the United States and elsewhere, but it could significantly alleviate the current energy crisis."

He said that if large plasma facilities were put to use nationwide to vaporize trash, they could theoretically generate electricity equivalent to about 25 nuclear power plants.

Americans generated 236 million tons of garbage in 2003, about 4.5 pounds per person, per day, according to the latest figures from the Environmental Protection Agency. Roughly 130 million tons went to landfills — enough to cover a football field 703 miles high with garbage.

Circeo said criticism of the technology is based on a lack of understanding.

"We are going to put emissions out, but the emissions are much lower than virtually any other process, especially a combustion process in an incinerator," he said.

Circeo said that both plants operating in Japan, where emissions standards are more stringent than in the U.S., are producing far less pollution than regulations require.

"For the amount of energy produced, you get significantly less of certain pollutants like sulfur dioxide and particulate matter," said Rick Brandes, chief of the Environmental Protection Agency's waste minimization division.

Geoplasma expects to recoup its $425 million investment, funded by bonds, within 20 years through the sale of electricity and slag.

"That's the silver lining," said Hillestad, adding that St. Lucie County won't pay a dime. The company has assumed full responsibility for interest on the bonds.

County Commissioner Chris Craft said the plasma process "is bigger than just the disposal of waste for St. Lucie County."

"It addresses two of the world's largest problems — how to deal with solid waste and the energy needs of our communities," Craft said. "This is the end of the rainbow. It will change the world."

Praise You in the Storm - Casting Crowns

Praise You in This Storm
words by Mark Hall/music by Mark Hall and Bernie Herms

I was sure by now, that You would have reached down
and wiped our tears away,
stepped in and saved the day.
But once again, I say amen
and it's still raining
as the thunder rolls
I barely hear Your whisper through the rain,
I'm with you
and as Your mercy falls
I raise my hands and praise
the God who gives and takes away.

Chorus:
And I'll praise you in this storm
and I will lift my hands
that You are who You are
no matter where I am
and every tear I've cried
You hold in your hand
You never left my side
and though my heart is torn
I will praise You in this storm

I remember when I stumbled in the wind
You heard my cry
You raised me up again
my strength is almost gone how can I carry on
if I can't find You
and as the thunder rolls
I barely hear You whisper through the rain
I'm with you
and as Your mercy falls
I raise my hands and praise
the God who gives and takes away

I lift my eyes unto the hills
where does my help come from?
My help comes from the Lord, the maker of heaven and earth
I lift my eyes unto the hills
where does my help come from?
My help comes from the Lord, the maker of heaven and earth

Crest of Waves - Coldplay

It could be worse
I could be alone
I could be locked in here on my own
Like a stone that's certain that drops
And never stops
I could be lost
Or I Could be saved
Calling out from beneath the waves
Beaten down by this ocean rain
Never again
Never again

Ohhh, Ohhh
Ohhh, Ohhh

Screaming out from the crests of the waves

It could be worse
Bittersweet
It could be snapped from the jaws of defeat
Like a light lit upon a beach
Where your heart only sleep
Oh
You want to stop before you begin
You want to sit when you know you could swim
You want to stop before you begin
Never give in
Never give in

Ohhh, Ohhh
Ohhh, Ohhh

Screaming out from the crests of the waves

Nothing matters
Except life and the love you make
Nothing matters
Except life and the love you make
Nothing matters
Except life and the love you make

Except life and the love you make

Screaming out from the crests of the waves

Screaming out from the crests of the waves
When your longing to be saved
Screaming out from the crests of the waves
When your longing to be saved
Screaming out from the crests of the waves

Who said Electric Cars are Boring??

A car that could save the planet—fast
Silicon Valley's big brains think they can beat Detroit and Tokyo and save the planet -- all while doing 0 to 60 faster than almost anything on the road.
 

SAN FRANCISCO (Business 2.0 Magazine) - Ian Wright has a car that blows away a Ferrari 360 Spider and a Porsche Carrera GT in drag races, and whose 0-to-60 acceleration time ranks it among the fastest production autos in the world. In fact, it's second only to the French-made Bugatti Veyron, a 1,000-horsepower, 16-cylinder beast that hits 60 mph half a second faster and goes for $1.25 million.

The key difference? The Bugatti gets eight miles per gallon. Wright's car? It runs off an electric battery.

Wright, a 50-year-old entrepreneur from New Zealand, thinks his electric car, the X1, can soon be made into a small-production roadster that car fanatics and weekend warriors will happily take home for about $100,000 --a quarter ton of batteries included. He has even launched a startup, called Wrightspeed, to custom-make and sell the cars.

But Wright isn't some quixotic loner. He's part of a growing cluster of engineers, startups, and investors, most of them based in Silicon Valley, that believe they can do what major automakers have failed at for decades: Think beyond the golf cart and deliver an electric vehicle (EV) to the mass market.

Indeed, the race for the new consumer EV has already begun: Just a year ago, Wright was working for his Woodside neighbor Martin Eberhard, co-founder of Tesla Motors, a startup that has 70 employees and a major investment from PayPal founder Elon Musk, which is building a mass-market rival to the X1. Wright left, believing he had an even better idea.

Beyond that, startups are forming to equip new "plug-in" hybrids that run almost entirely on their electric motors. And around the country, a handful of other exotic EVs are showing up on the road -- including George Clooney's new ride, a $108,000 commuter coupe that's just 3 feet wide.

The more that cars become technology platforms, the more the future plays into the hands of people like Wright and Eberhard. "Automakers can't do this," Eberhard says. "If you drill into the complexity of an electric car, it's not the motor, it's the electronics and battery system, which car companies aren't good at."

Adds Musk, "The time is right for a new American car company, and the time is right for electric vehicles, because of advances in batteries and electronics. Where's the skill set for that? In the Valley, not Detroit."

Wright's garage-born heroics are, in many respects, long overdue. After all, electric cars predated the gasoline combustion engine. But they soon headed for museums, replaced by gas engines. A mid-1990s wave of all-electric cars was short-lived. GM Research spent more than $1 billion to introduce a short-lived electric vehicle -- and were soon replaced by Toyota's hot-selling hybrid gas-electric Prius.

So how do you build the EV of the future on a six-figure budget when GM couldn't do it with more than $1 billion? For starters, you get all the basic parts off the shelf. By itself, all the hardware in the X1 is nothing new. The X1's real secret is how Wright engineers it all to keep the car in optimum race mode whenever you hit the accelerator.

Proving grounds

Last November, Wright towed the X1 to a racetrack near Sacramento to see how his prototype would do against a Ferrari and a Porsche. On paper, a win seemed guaranteed. But he hadn't yet run the car full out.

In the first matchup, the X1 crushed the Ferrari in an eighth-mile sprint and then in the quarter-mile, winning by two car lengths. In the second race, against the $440,000 Porsche, the two cars were even after an eighth of a mile. But as the Porsche driver let out the clutch in a final upshift, his tires briefly lost traction. The X1, blazing along in its software-controlled performance mode, beat the Porsche by half a car length.

It never occurred to me that I would lose," says Kim Stuart, the Porsche's driver. "It was like a light switch. He hit the pedal and was gone."

So what now? Wright isn't sure himself. Only 50 or so people have driven the car, and Wright has just begun to hold his hat out for potential investors. With $8 million in funding, he says, he is convinced he can put a consumer version of the X1 into production that meets federal safety standards, has a 100-mile range, and recharges in 4.5 hours.

To bring any EV to the masses, of course, will require much improved battery technology. But a handful of startups backed by Valley VCs are claiming that big advances are just around the corner. Menlo Park-based Li-on Cells claims that its technology will double the performance of lithium-ion batteries for about half the cost.

Thus, the X1 and the Tesla could be just the things to throw the EV race into high gear. As battery prices drop and performance improves, the cars could come within reach of a wider audience. And if oil prices keep climbing, more and more consumers will demand alternatives that are punchier than a Prius.
