Google Glass is the future – and the future has awful battery life

  • google-project-glass.jpg

The concept of wearable tech is really buzzing right now as pundits tout smart eyewear, watches and other connected devices as the future of tech. It makes sense, of course — smartphone growth is slowing and people need something to hold on to — but the early “Explorer” version of Google’s highly anticipated Google Glass headset has major problem that could be a big barrier for widespread adoption: Awful battery life.

Battery longevity is a problem that plagues all portable consumer electronics. Just imagine how much easier life would be if you could go days or even a week without charging your laptop, smartphone and tablet. Where smartphones are concerned, we have now accepted the reality of battery limitations and adopted the routine of charging our phones about once a day with normal usage.

Charging a handset once a day is fair for a portable device that has become such a core part of our lives. The bar has been set. And as industry watchers try desperately to convince us that wearable tech is the next big thing, serious concerns about battery life are now arising.

Things are looking good where smartwatches are concerned. The popular Pebble seems to go between five and seven days before it needs to be charged thanks to the low-power E Ink display, and Apple is reportedly aiming to build an “iWatch” that lasts between four and five days per charge. But for all the hype surrounding another category of wearable devices — connected eyewear — early tests with Google Glass suggest battery performance may be absolutely awful.

In a review of the Google Glass Explorer Edition headset, Engadget’s Tim Stevens paints a worrying picture of the device’s battery life. With what he considers to be average usage that included reading emails and capturing short videos as well as some photos, Glass only lasted Stevens five hours before it “unceremoniously shut itself down.” That’s pretty bad, but it gets worse. If the user captures longer videos and uses Glass a bit more regularly, Stevens believes the headset will only last “a couple of hours” before the battery dies.

A device that only lasts two hours between charges is not the future of tech.

Google’s Explorer Edition headsets may still undergo some changes before Google Glass launches next year, and battery life clearly needs to be a focus if Glass is to be anything beyond an expensive niche toy destined to gather dust in a drawer a few short weeks after being purchased.

Editor's note: This article is adapted from the Spring 2013 issue of City Journal.

Shortly after Barack Obama won reelection in November, New Jersey Governor Chris Christie pointed out that Republicans’ cloudy political prospects had a bright silver lining. “One of the reasons you have 30 Republican governors in America, and why we’re the only organization to add Republican strength,” Christie said, “is because people see us getting things done.” 

Christie’s stance countered most of the elite postelection commentary, which gleefully pronounced the Republican Party’s political irrelevance. But the governor was right. 

Since Obama first took office in 2008, Republicans have picked up a net nine governorships, bringing their total to 30 states, which hold nearly 184 million Americans. In 24 of those states, containing 157 million Americans, Republicans also control the legislatures. 

Democrats boast similar power in just 12 states, with a population of 100 million. Even Republicans’ unimpressive national showing last November didn’t reverse their state-level momentum.

It’s becoming clear that the Republican governors plan to lead in ways consistent with the reform agendas that got them elected.

The next-wave Republican governors have ignored proclamations that President Obama’s victories have vaporized fiscal conservatism and opened a new era of American big government.

At a time when Washington policymakers seem paralyzed by our toughest problems, these state-level revolutionaries have restrained government growth and radically reformed local tax codes.

They’ve made their states friendlier to business, reshaped government-employee pension systems to reduce state debt, and restrained the power of public-sector unions over state and local budgets. Some have even proposed eliminating income and corporate taxes.

Christie, whose stock has risen in New Jersey as he heads into a reelection battle this year, believes that the next national leadership of the Republican Party will emerge from the ranks of its effective governors. “I don’t think this is a core philosophical examination we have to go through,” he has observed. “What this is about is doing our jobs.”

Few observers predicted this Republican resurgence back in 2008, when elections not only handed the Democrats the White House and Congress but also cemented their control of 29 governors’ mansions.

Even as the country seemed to lurch leftward, however, state voters began to revolt against Democratic governors’ tax increases.

In 2009, Christie defeated Democratic incumbent Jon Corzine with a platform that rejected new taxes. Over the previous eight years, Corzine and his Democratic predecessor Jim McGreevey had raised taxes by more than $5 billion. 

McGreevey boosted taxes and fees $3.6 billion between 2002 and 2004 alone, raising everything from income taxes to levies on home sales. Corzine followed in 2006 with his own $1.1 billion sales-tax hike.

Three years later, he slapped a temporary income-tax surcharge on households making more than $400,000 a year, part of another proposed $1 billion in new taxes. But actual tax collections imploded, leaving Christie with a $4 billion budget deficit when he took office in 2010.

Christie ran enormous political risks in trying to shrink that deficit. Despite discontent over the high taxes, polls showed that voters wanted higher levies on the rich, so that the state could continue a popular program of property-tax rebates for homeowners. And though the voters favored winning concessions from government workers, they also wanted the state to keep subsidizing public schools richly.

Christie disagreed. He chose not to renew the surcharge on high earners and slashed aid to municipalities. He also reduced the property-tax rebates; after all, property taxes are imposed by localities, so the rebates amounted to a state subsidy that let cities and towns avoid making tough budget decisions.

When homeowners complained, Christie urged them to vote against the expensive municipal and school budgets that were driving their ever-rising property taxes. Voters responded, defeating nearly 60 percent of the school budgets proposed in 2010. Christie’s reforms slashed state spending by nearly 9 percent and balanced the state budget without new taxes.

Christie then pressed the legislature to pass reforms that restrained municipal spending, including a cap on annual property-tax increases. 

He also signed off on roughly $347 million in business tax cuts, though he has yet to find the revenues to make good on his pledge to lower Jersey’s income tax. Christie’s favorability rating was just 44 percent after his first budget passed, but as Jerseyans watched his strategy play out, his popularity grew.

Even before his effective and sympathetic response to Superstorm Sandy, more than 50 percent of voters approved of the job he was doing; since then, his popularity has soared.

“Despite the challenges that Sandy presents for our economy, I will not let New Jersey go back to our old ways of wasteful spending and rising taxes,” Christie recently announced. “We will deal with our problems, but we will continue to do so by protecting the hard-earned money of all New Jerseyans first and foremost.”

A year after Christie’s victory came the 2010 elections, when 26 governorships were up for grabs. Republicans wrested 11 of them from Democrats and lost only five, an impressive tally.

Perhaps the most ambitious of the 2010 crop of reform governors is Michigan’s Rick Snyder, a former venture capitalist with no previous experience in office.

Snyder initially received less national attention than Christie or Wisconsin’s Scott Walker, whose battle with government unions grabbed headlines throughout 2011. 

Perhaps Snyder’s post-partisan image was what kept him off the national press’s radar for so long: he ran as a wonk who would use his business acumen to fix the state’s finances.

In his first budget, Snyder sought to close a $1.5 billion deficit while pushing—successfully, as it turned out—to get rid of the hated Michigan Business Tax. 

The MBT didn’t just tax businesses’ profits, as most corporate taxes do; it taxed their revenues as well, meaning that firms had to pay even when they weren’t making money. 

Politicians and policy experts in Michigan had long acknowledged that the MBT was one of the nation’s worst corporate taxes and that it drove away business. But it brought the state $1.7 billion in yearly revenue that no previous governor had wanted to forgo.

Snyder’s tax-reform plan was audacious. To make up for the lost MBT revenues, he proposed a flat corporate levy; jettisoning $400 million in targeted corporate tax credits, which had tried to keep particular companies in the state; and (most controversially) taxing the pensions of all Michigan residents.

Michigan, Snyder observed, was one of only three states that exempted pensions from income tax. The anomaly had originated in the mid-sixties, when state pols and public-sector unions reached a deal to exclude government pensions from taxes and public anger over the favoritism led to a broadened exemption.

Snyder’s call to tax pensions understandably upset retirees and government-worker groups, who threatened to try to recall the governor. But he persisted, and the recall idea fizzled.

The Michigan legislature eventually agreed with him and reshaped the state’s tax code. The new arrangement moved Michigan’s corporate levy from next-to-worst in the Tax Foundation’s national rankings to 18th best. “The Wicked Witch is done,” Snyder said.

Nor was that the end of Snyder’s reform drive. Last year, he lowered Michigan’s personal income-tax rate. And now he’s seeking to eliminate the state’s so-called personal property tax, which is actually an outdated tax on business equipment. Snyder’s changes are “unshackling the state from its obsolete economic past and positioning it for new prosperity,” noted the Detroit News.

In Kansas, meanwhile, Governor Sam Brownback is pushing to extend a tax-reform program. Brownback roared into office in 2011 proposing to lower income-tax rates and to regain the lost revenue by capping some popular tax expenditures, like the mortgage-interest deduction.

Republicans in the state legislature, balking at ending the popular items, passed a tax-cut package without them, lowering the state’s income-tax rate from 6.45 percent to 4.9 percent.

“The governor said early on… ‘Go bold.’ And we did,” said Mike O’Neal, Speaker of the Kansas House of Representatives. Brownback paid for the tax cut in part by keeping state spending flat and by using increased revenues from a modest upturn in the state economy. He’s now hoping to end enough tax-code deductions and loopholes to save Kansas more than $1 billion in revenue.

States are laboratories of democracy, in Justice Louis Brandeis’s famous formulation, and the very different experiments that their Republican and Democratic governors conduct over the next few years—especially on issues that go to the heart of economic competitiveness—will be eye-opening.

In the months since President Obama’s reelection, it’s becoming clear that the Republican governors plan to lead in ways consistent with the reform agendas that got them elected. How they fare may steer the Republican Party’s course more decisively than any soul-searching in Washington does.

America's engine of the future to get 'Made in China' label

  • opoc-660.jpg

Thanks to generous support from a foreign backer, there is renewed hope for an American attempt to revolutionize, modernize and sanitize the automobile engine.

The catch?  The finished product will be stamped “Made in China.”

EcoMotors, a startup engineering company based in Allen Park, Mich., plans to produce up to 150,000 of its opposed-piston, opposed-cylinder (OPOC) two-stroke engines annually in a factory funded by Zhongding Power. The facility will be located in China’s Anhui Province, west of Shanghai.

EcoMotors CEO Don Runkle told FoxNews.com that Zhongding has committed to building a plant for the engines with the hope of supplying generator companies and builders of medium-duty trucks.

“We have talked to a number of automobile manufacturers in the United States, as well as in China,” Runkle said.  He added that EcoMotors has “a letter of intent with Generac,” an American manufacturer of generators that currently buys engines from John Deere and Iveco.

Although Chinese-built generators and motorcycles are becoming more common in the United States, engines produced there have rarely seen duty in American automobiles. The first was when General Motors dropped a Chinese-made 3.4-liter V-6 into its 2005 Chevrolet Equinox and Pontiac Torrent crossovers.

In 2010, when Zhongding agreed to invest up to $18 million toward engineering costs for the OPOC engine, Runkle announced that “this initiative will create a range of high-skill R&D jobs here in southeast Michigan, further underscoring the region's critical role as the incubator of tomorrow’s high-efficiency powertrain solutions.”

The OPOC two-stroke engine is a markedly different concept than the four-stroke engines fitted to most modern automobiles. While two-strokes are generally lighter, have fewer moving parts and a higher power density than comparable four-strokes, they are often not as durable and burn a lot of oil, resulting in worse emissions. EcoMotors claims to have overcome these hurdles with its new technology.

The EcoMotors-designed power plant does without valves and cylinder heads, and places two pistons facing one another in each cylinder like boxers' gloves, with the pistons in turn connected to identical counterparts in an adjacent cylinder. The expansion stroke on one side creates a compression stroke in the other.

“Our innovation is an unusual engine architecture,” Runkle said.

The company says the motors can be configured to run on a variety of fuels, including gasoline and diesel, and will be cheaper to build while delivering between 20 and 50 percent better fuel economy than conventional internal combustion engines, depending on their application.

Production of the OPOC is set to begin in 2014.

Dodge "Defiance" Lawkeeper ready to patrol the future

  • dodge-defiance-660.jpg

If you thought the Dodge Charger makes for a pretty mean-looking cop car today, wait until 2046.

The automaker has co-developed a post-apocalyptic version of its police cruiser for the Syfy series “Defiance,” which is set on a future Earth where civilization has been accidentally destroyed by visitors from outer space who came to settle the planet, unaware that it was populated by humans driving Hemi-powered muscle cars.

The vehicle used in the show is heavily modified with off-road wheels and tires, a strengthened chassis, jury-rigged armor covering the windows and an exoskeleton-type frame to protect it from some of the huge and horrible wild beasts that the humanoid aliens brought along with them from their home planet.

Instead of that Hemi, the car is powered by a “petrohop” supercharged-hybrid powertrain, complete with a glowing, blue manifold of some sort sticking out of the hood.

The rat-rod looking ride is driven by Chief “Lawkeeper” Jeb Nolan, played by Grant Bowler, who patrols the streets of the titular city of Defiance, a boom town built on top of the ruins of St. Louis.

With a reboot of “Mad Max” in the works for next year, we could be in for one very awesome dystopian drag race at a classic car show in our future.

Assuming the aliens don’t ruin it for us.

The future of wine?

It’s hard to talk about wine without evoking the tokens of tradition: ancient terroir, age-old techniques of production, vineyards held by single families for successive generations. 

The world of wine characteristically embraces permanence over progress, a sense of aristocratic reverence over a democratic spirit of reform. 

Nevertheless, the way wine is bought and sold, and even appreciated, is necessarily changing as more and more commerce predictably moves online.

While Americans lack the storied heritage of wine appreciation their European counterparts rightfully lay claim to, they have much more expansive palettes as a result of more cosmopolitan offerings.

I had the opportunity to chat recently with one of the pioneers of Internet wine retail, Gary Vaynerchuk, the creator of Wine Library TV, a daily webcast devoted to all things vinicultural. Vaynerchuk was one of the prime movers behind not only selling wine online but also harnessing the potential of social media to promote more esoteric varietals to new customers.

According to Vaynerchuk, the tectonic shift in the wine industry has been brought about by a “democracy of information” that shifts the balance of power “away from the gatekeepers and towards the masses.” 

While this consumer-centric revolution poses new challenges for wine retailers to remain competitive in an increasingly open market, it encourages wine drinkers to “stretch their own palettes,” discover new wines, and mine their Twitter and Facebook accounts for clues on what to try next. 

Information about wine is no longer rationed out by “Parker and the Wine Spectator crowd” whose reviews once essentially predetermined what sold and what sunk. One consequence of this is that wine appreciation has become more hip, magnetizing a much younger generation to connoisseurship.

These shifts generate new opportunities for wine retailers to aggressively expand but also pose unique challenges as well: “ I don’t think people realize how hard it is to be good at having a relationship with the end-consumer. It’s very, very hard to be good at that.... They’re going to have to figure out how to tell a story, they’re going to have to figure out how to deliver a truly unique experience...”

Does this portend the end of the traditional wine shop? No, but they will have to learn quickly how to adapt to a rapidly evolving business environment: 

“Physical stores are going to go away eventually in the way that we know them now. They’re going to have to deliver other experiences and other things. And so, you know, I don’t think superstores like Wine Library or Zachys or things of that nature are going out of business anytime soon.” 

And as the consumer embraces a spirit of experimentation, the market will splinter into distinctive concentrations of interest: “I see more and more niche wine stores popping up...I think there’s a lot more specialization to come. I think there’s going to be a Gary V. of Napa. I think there’s going to be a Robert Parker of Rhone Valley. I think there’s going to be a Wine Spectator of Central Tobago. I think niche expertise has still not flourished the way that it can, and I think people are missing the opportunity.”

And no wine drinking community is better positioned to reap the benefits of this sea change than the American one. While Americans lack the storied heritage of wine appreciation their European counterparts rightfully lay claim to, they have much more expansive palettes as a result of more cosmopolitan offerings. “I actually think that if you are an American wine drinker, that you have a dramatically more interesting view of the wine world, a more expanded and challenged palette. I am appalled at going to Barossa Valley or to Rioja and asking what they think of Gigondas, or Corvina, or Chateauneuf, or Chenin Blanc from South Africa, and getting answers from ten-year wine makers that say, “Oh, I’ve never had one.”

And so the average American wine drinker is simply superior to the average European one? On this score, Vaynerchuk pulls no punches: “I actually don’t even think it’s close. I think the US wine consumer specifically is the best wine consumer in the world.’ In fact, the greater exposure to a much broader selection of international wines means “that a serious wine person in France has a more limited palette, in my opinion, than a casual one in the US.”

In general, Americans have become much more savvy about the way they eat and drink, both more discerning and demanding.”We are definitely eating and drinking better as a culture in the US, and it’s become more European that way, and I think we will continue to.” 

Vaynerchuk has seen the blossoming maturity of American consumption with respect to beer as well: “Microbrew’s been happening in a big way in the early ‘90s too. I mean I remember thinking, “Should I learn about microbrews instead of wine?”

Given the historical preference in the US for beer, a turn towards the market dominance of wine would be a powerful sign, both economic and cultural, of the seismic transformation cyber-retail has wrought. 

Is the overtaking of beer by wine a real possibility in a country that has always chosen hops over grapes? Vaynerchuk delivers his prediction with all the precision of a tweet: ‘Yes, absolutely. I’m sure I will see it. I feel very good about that.”
