Bob Purcell, known in the automotive industry as the father of General Motors GM EV1 plug-in car, has been in the automotive business for 45 years, the last 20 of which have been dedicated to electric vehicle development. And even though he’s 60 years old and should be starting to think about retirement, he’s not about to quit now — not when the industry seems so close to a breakthrough. “I’m not going to retire until I get one to high volume for real,” said Purcell. “I’ll be honest. I think we’re there.”
Comments: (The text was oddly difficult to copy... so here´s the takeaway info... ) This development is a motor in each wheel, thus eliminating drive shaft, tranny, axle, differential, and lots of weight. Interesting concept... He has investors and is marketing to all auto manufacturers on all populated continents.
EVs need battery improvements - not the motor. Electric motor efficiencies are greater than 90% so where you place it (them) in the vehicle is nowhere near as important as a battery that can get you 300 miles between charges. That, and the ability to charge the battery in 15 minutes are the breakthroughs needed. Neither are close.
Bob, I have two words for you: "Energy Density". The battery pack for the Chevy Dolt, er, Volt is "T" shaped, about 4 feet across the top and 6-8 feet long and weighs about 400 lbs. It contains the rough equivalent energy of 1 gallon of gasoline.
What do you do with a car that it´s battery is dead and will not take a charge after 5 years and it cost 5 to 10 thousand dollars to replace? The car as it sits is worthless! I doubt they will ever over come that big problem!
30 minute charge time on 120V. 200 mile range on 30 minute charge. Range includes use of AC or heater and stereo. Cost of small electric car $20k. No issues in extreme cold or heat. No danger in case of accident and breakage of batteries. Battery replacement less than $1000, good for 5+ years No reduction in performance over the 5 years Decent acceleration
Accomplish this you will sell tons. Until then, shut up.
Until the infrastructure is there, electric cars are nothing but short-range commuters. What is needed is ´´service stations´´ that can change out a battery pack in just a few minutes- comparable to the time it takes to fill up with gas. That would require standardization of battery packs among the auto manufacturers, as well as better batteries that increase driving range to at least 100 miles.
Electric cars have been the "car of the future" for more than a century, I wouldn´t invest $10 in an electric car company or take one for free if I had to give up my real car.
Expect a limited heater, limited-AC microcar that will go about 25-35 miles until it STOPS if driven at highway speeds. If you use a heater or AC, range will substantially less. In southern CA, if you live close to work, drive city streets at low speeds and work has a special power plug installed for BIG bucks, this could be adequate as a commuter only car. The only way to exceed this is with $50K of batteries or more a la Fiskar, now bankrupt.
Most of us would find it an expensive, near useless toy. Expect less than 3% market penetration EVER unless they force gasoline up to $25/gallon, which they are trying as hard as they can to do.
OK, putting the motors at the wheels [as on the Mars Curiosity Rover, and IIRC the Apollo moon car, etc.] is a good design decision. As posters note, electric locomotives have done this since maybe the 1920s? But eliminating a lot of driveline losses isn´t "solving" the real problem of battery-powered cars.
In terms of physics laws, what battery-car buffs are telling us is that they know how to make water run uphill. Or that "that´s all that´s left" to "figger out."
Electric cars [hybrids, basically] are/can be workable. A workable hybrid generates electricity on-board from a fuel-powered engine. That´s how a "diesel" locomotive works. Very efficient. But the efficiency comes from 3 things: a. eliminating losses from long-distance transmission of electricity; b. eliminating driveline losses by gearing a motor directly to each drive axle; and c. carrying a high-energy-density fuel on-board.
But, a locomotive doesn´t need lots of interior space, or have constantly-changing torque loads. Railroads have spent hug amounts of capital taking grades out of their tracks, and trains run at steady speeds as much as possible.
#7´s post is quite good. I would add 2 points: a. The gallon of gas the 400 pounds of batteries is compared with weighs just 5 or 6 pounds; and b. a battery car hauls that 400 pound load whether the batteries are "full" or "empty." That dead load wastes a lot of energy. The problem is not soluble with any present or foreseeable battery technology [he says obviously].
A Portland, Oregon man urinated in a Mt. Tabor reservoir Wednesday causing the city to take its critical water supply off line and dump millions in gallons of water. [Snip] officials saw five people throwing objects into the reservoir, while one person began to urinate into it [Snip] David Shaff, said that because of this incident, roughly 7.8 million gallons of drinking water will be discarded. He said the bureau often finds dead animals in the same drinking supply but the water isn’t dumped. “This is different,” Shaff told the newspaper. “Do you want to drink pee?"
The Himalaya´s mysterious Abominable Snowman might harbor an even deeper mystery, according to an Oxford University geneticist who says he has sequenced the mythic beast´s DNA and proved its existence. [Snip] Bryan Sykes, a professor of genetics at Oxford, sequenced DNA taken from two unidentified animals killed in Himalaya ranges of India and Bhutan in recent decades. The small samples - including a single hair found a decade ago, and the jawbone of a mummified animal discovered in the 1970s by a hunter - were compared to a database of thousands of known animals,
Bigfoot is real, and now at least one scientist claims there is proof. A group of Sasquatch researchers who have been collecting over 100 pieces of evidence over the past five years screened "never before seen HD video" of the alleged creature at a news conference in Dallas on Tuesday. [Snip] Dr. Melba Ketchum, who has led the group of researchers called the Sasquatch Genome Project, has been working on a $500,000 analysis of DNA samples from an unknown hominin species. Ketchum calls the project "a serious study" that concludes the legendary Sasquatch exists in North America and is a
The contrast between the two headlines couldn’t have been more stark. [Snip] Royal Mail turned a $650 million profit last year while the Postal Service was racking up a $15.9 billion loss. [Snip] British governments [Snip] ended the agency’s monopoly on first-class mail in 2006 and passed a privatization law in 2011. [Snip] Twenty-five of the European Union’s 27 nations have repealed their postal monopolies and set up corporate entities to deliver the mail. Private investors own 100 percent of the Netherlands’ post office, and substantial stakes in its German, Belgian and Austrian counterparts.
Chew on this. A team of MBA students were the recipients of the 2013 Hult Prize earlier this week, providing them with $1 million in seed money to produce an insect-based, protein-rich flour for feeding malnourished populations in other countries. The product is called Power Flour. [Snip] in Mexico, where a population of roughly 4 million live in slum conditions with widespread malnutrition. "We will be starting with grasshoppers," Ashour said. He noted that the insect is already familiar to the local diet and currently sells at a premium because of a three-month harvesting season and because grasshoppers are typically
BERLIN — It is an audacious undertaking with wide and deep support in Germany: shut down the nation’s nuclear power plants, wean the country from coal and promote a wholesale shift to renewable energy sources. But the plan, backed by Chancellor Angela Merkel and opposition parties alike, is running into problems in execution that are forcing Germans to come face to face with the costs and complexities of sticking to their principles. German families are being hit by rapidly increasing electricity rates, to the point where growing numbers of them can no longer afford to pay the bill. Businesses are more
Bill Gates is the richest American for the 20th year in a row and has reclaimed the title of world’s richest person from Mexico’s Carlos Slim with a net worth of $72 billion. Warren Buffett, again number two [Snip] The 400 wealthiest Americans are worth a record $2.02 trillion, roughly equivalent to the GDP of Russia. That is a gain of $300 billion from a year ago [Snip] only 15 saw their fortunes drop, including T. Boone Pickens, whose costly bets on wind energy lost him his billionaire status, and Manoj Bhargava, whose 5-Hour Energy drink firm has been hit
TUSCALOOSA, Ala. — To understand just how complex and sometimes chaotic the organizational structure of a big-time college football program can be, one would only need to have followed the developments surrounding Texas A&M this summer. [Snip] The one exception, of course, to Saban´s single-minded, almost robotic approach occurred last season when Manziel became legend at the Crimson Tide´s expense. For 60 minutes, he drew Alabama into the chaotic, seat-of-your-pants world of Johnny Football and came out the other side as a national phenomenon, winning the game, 29-24, and ultimately the Heisman Trophy. For Alabama, though, redemption this week in College Station, Texas,
Rafa Nadal took the upper hand in the U.S. Open men´s final by winning the opening set 6-2 against world number one Novak Djokovic on Monday. The French Open champion broke the top-seeded Serbian in the third game when he blasted a forehand winner to take a 2-1 lead. World number two Nadal broke Djokovic again in the seventh game for a 5-2 edge when he won his eighth consecutive point after winning a challenge on a Djokovic ball ruled in by the linesman. Nadal, dashing around the court with speed and ease, played a much cleaner set in windy
Peking duck is no longer a dish in China, it´s a craze. Rubber ducks have been appearing on lakes, some used to commemorate the outlawed democracy movement, some to promote businesses and others just set out for fun. [Snip] The craze began in May, when a 54-foot duck made by Dutch artist Florentijn Hofman was floated in Hong Kong´s Victoria Harbor. Copycat versions of the work made in China began appearing all over. The ducks showed up in at least 16 cities, used mostly to advertise real estate.
Diana Nyad´s 110-mile swim from Cuba to Florida has generated positive publicity and adoration for the 64-year-old endurance athlete — along with skepticism from some members of the small community of marathon swimmers who are questioning whether she accomplished the feat honestly. On social media and the online Marathon Swimmers Forum, long-distance swimmers have been debating whether Nyad got a boost from the boat that was accompanying her — either by getting in it or holding onto it — during a particularly speedy stretch of her swim. They also question whether she violated the traditions of her sport — many
All summer long, Texas coach Mack Brown tried to paint the most pleasant picture of his program, denying the notion that he was under pressure to win big this season. Halfway across the country, Southern California athletics director Pat Haden posted a video on the school´s athletics website declaring emphatically that Lane Kiffin was not on the proverbial hot seat. Just two weeks into the season, those sunny outlooks for two of college football´s mega-programs are already in serious doubt. Brown might not publicly acknowledge that his tenure at Texas is in jeopardy, but his actions Sunday said it all.
Last summer on his $100 million family tour of Africa, Barack Obama hoped for a priceless photo op with Nelson Mandela, the ailing freedom pioneer who went from prison cell to the presidency of South Africa. Mandela´s family suggested that wouldn’t happen. So, the Obamas did a photo op in Mandela´s former prison cell. Which Obama’s White House quickly tweeted upon word of the icon´s passing at 95. [Skip] But Obama was also caught staring at television coverage of Mandela’s passing, which became Obama’s Photo of the Day.
Hardly a week goes by without Hillary Clinton receiving another award. Last month she was named a “Global Champion” by the International Medical Corps, received the American Patriot Award at the National Defense University Foundation and the Hermandad Award from the Mexican American Leadership Initiative. [Snip] At this rate, if a bunch of elderly left-wing Swedes toss her the Nobel Peace Prize early on, the way they did to Obama, it will barely rate mention among all the other glittering trophies that have been bestowed on a woman whose only actual accomplishment was being married to a crooked governor with
Speaker John Boehner said his party should support gay Republican congressional candidates and urged his colleagues to “be a little more sensitive” when running against women. “Some of our members just aren’t as sensitive as they ought to be,” Boehner said. When asked if he thinks his party should support gay candidates, Boehner simply said: “I do.”
Denver - A baker who refused to make a wedding cake for a same-sex ceremony must serve gay couples despite his religious beliefs or face fines, a judge said Friday. The order from administrative law judge Robert N. Spencer said Masterpiece Cakeshop in suburban Denver discriminated against a couple "because of their sexual orientation by refusing to sell them a wedding cake for their same-sex marriage." The order says the cake-maker must "cease and desist from discriminating" against gay couples. Although the judge did not impose fines in this case, the business will face penalties if it continues to turn away gay
In February, the Bush family’s personal emails were hacked by Guccifer, a hacker who uncovered photographs of former President George H. W. Bush in a hospital bed and George W. Bush’s oil paintings in the process. It seems Guccifer has struck again, this time targeting former President Bill Clinton and the Clinton Library. The hacker has reportedly uncovered doodles of Clinton drawing on what were, at the time, classified documents. Among the doodles is apparently a picture of a penis. The document uncovered is a briefing of the strategic measures the United States could take prior Clinton’s decision to intervene in
Amid an array of “knock-out” attacks against a number of Jews in Brooklyn’s Crown Heights neighborhood, a city councilwoman pointed to the success of the Jewish community as triggering the aggression. Councilwoman-elect Laurie Cumbo emphasized that while she “admire[s] the Jewish community immensely” for its work ethic, black teens may see it differently. “While I personally regard this level of tenacity, I also recognize that for others, the accomplishments of the Jewish community triggers feelings of resentment, and a sense that Jewish success is not also their success,” Cumbo, who was recently elected, wrote in a letter. Chief among the issues
On Tuesday, The Boston Globe reported that Onyango “Omar” Obama, uncle to President Obama, says that his famous nephew stayed with him while a student at Harvard Law School in the 80s, in contradiction to The White House’s contention that the two had never met. At Thursday’s White House daily briefing, Press Secretary Jay Carney confirmed that the President had, in fact, briefly stayed with “his father’s half-brother,” as Carney described Omar Obama, and that no one had actually asked the President about it when the White House initially commented. The 69 year-old Omar Obama has been facing deportation back
Former President Bill Clinton shared an anecdote regarding Nelson Mandela and the aftermath of his impeachment Friday on CNN. Clinton revealed shortly after the “impeachment business” finished on Capitol Hill, Rep. Henry Hyde (R., Ill.) who managed the impeachment trial requested a meeting at the White House. The former president granted the meeting out of lessons of humility and forgiveness he learned from Mandela, he said: BILL CLINTON: I remember one day, oh, about a month after the whole impeachment business was over, Henry Hyde, who had run the whole show, unbelievably enough, maybe a few months after, it was
The world premiere of the “Ballad for Trayvon Martin for Orchestra and Jazz Quartet” is set for tonight. Princeton University’s director of its jazz-studies program composed the work in honor of the Florida teen. Anthony D. J. Branker told the Star-Ledger that the piece is intended to “be a form of healing” after Martin’s death and the controversial court case that followed it. The ballad, which will be performed by the university’s official orchestra and jazz ensemble, is intended to be a tribute to victims of racial violence, Branker explained. He hopes that the performance will be “one that speaks to
WASHINGTON – A fourth straight month of solid hiring cut the U.S. unemployment rate to a five-year low of 7 percent in November, an encouraging sign for the economy. The Labor Department says employers added 203,000 jobs, nearly matching October´s revised gain of 200,000. The job gains helped lower the unemployment rate from 7.3 percent in October. The strengthening job market is likely to fuel speculation that the Federal Reserve may start to scale back its bond purchases when it meets later this month. The economy has now generated an average of 204,000 jobs from August through November. That´s up
WASHINGTON — President Barack Obama has high praise for potential 2016 contenders Vice President Joe Biden and former Secretary of State Hillary Clinton. “I think Joe Biden will go down in history as one of the best vice presidents ever, and he has been with me, at my side, in every tough decision that I’ve made,” Obama told MSNBC in an interview Thursday held at American University. “Hillary, I think, will go down in history as one of the finest secretaries of state we’ve ever had, and helped to transition us away from a deep hole that we were in,
WASHINGTON — Without Nelson Mandela, there might never have been a President Obama. That is the strong impression conveyed from Mr. Obama, whose political and personal bonds to Mr. Mandela, the former South African president, transcended their single face-to-face meeting, which took place at a hotel here in 2005. It was the fight for racial justice in South Africa by Mr. Mandela that first inspired a young Barack Obama to public service, the American president recalled on Thursday evening after hearing that Mr. Mandela, the 95-year-old world icon, had died. Mr. Obama delivered his first public speech, in 1979, at
