    The (Slightly) Poorer Man's Tesla: ECOS Harbinger

    By Mike Spinelli Posted on 11.20.2009 6 Comments

    For around 13 grand, Electric Cars of Springfield (ECOS) will turn your old beater into an all-electric commuter car. But for a few bucks (around $77,000) more, they'll build you an entire, turn-key sports car. It's called the Harbinger. It hits an electronically limited 117 miles per hour, gets to 60 mph in five seconds and undercuts the Tesla roadster on price. Did I mention it comes with Lamborghini-style scissor doors?

    There are 35 states with cities named Springfield... the particular Springfield where the ECOS Harbinger is made is in Illinois, the state capital. I cannot find any data on the body-- if it's made in-house, that's a plus compared to the Tesla Roadster that gets its body from Lotus in England. The Harbinger uses "prismatic" lithium iron phosphate (LiFe PO4) batteries, which I would prefer over the lithium ion cells used in the Tesla. LiFE PO4 batteries can't hold as much charge per kilogram of weight, but they are far safer than the lithium ion batteries in the Tesla. Tesla's batteries use extensive, complex safeguards to prevent thermal runaway-- burning or exploding-- I prefer the simplicity of prismatic batteries. The extra hardware to prevent the thermal problems of lithium ion batteries reduces any gains for the extra expense and weight compared to prismatic cells. "Prismatic" refers to the form factor of the battery-- rather than cylindrical shapes such as the AA, AAA, C, and D-cell batteries we are used to, prismatic batteries are rectangular in shape-- they make better use of space since prismatic cells can be arranged like textbooks on a bookshelf. "Prismatic" is a term used in optics that refers to transparent objects that refract light into the colors of the rainbow, or spectrum. But in this case, prismatic refers to the original Greek, that is, prismatic batteries have flat, parallel sides.

    The plastic tube Sandy Hawkins hands me looks more like a toy horn than a medical device. Blowing into it, he tells me, will do wonders for my chest cold. I glance at the dozen or so people enjoying their mid-afternoon Starbucks and give it a few skeptical puffs.

    Before I saw the video of the flute being used (below), I was under the mistaken impression that this device generated some kind of loud noise, which it does not-- its only resemblance to a real flute is its shape. If it did generate loud noises, I could imagine several reasons you might want to control it with prescriptions-- but this thing is hardly audible! It makes me angry that we have more bureaucratic nonsense preventing this device from being used on a broad basis! It would not surprise me at all if this flute started being bootlegged like CDs, name-brand watches, and sneakers. KISS: Keep It Simple, Stupid. Thank you for doing exactly that, Mr. Hawkins, even if the medical establishment wants to muck it up for those of us that might actually need it.

    Bolivia Is the Saudi Arabia Of Our Battery-Powered Future

    By Posted on 10.23.2009 13 Comments

    Bolivia is primarily known for two things: being the poorest country in South America, and having a president with a terrible haircut. However, it might soon be known for a third thing: lithium. Turns out Bolivia has the world's largest reserves of the light metal, and according to Foreign Policy, that positions Bolivia as the Saudi Arabia of our carbon-less, battery-powered future.

    If you google St. Andrews Air Battery (abbreviated STAIR), and browse other air battery technologies, you'll see there is good reason to believe we may soon be able to make batteries that have far greater energy density, meaning we'll need far less of anything such as lithium to make a battery with much greater range, and that is much less expensive. The concept of air batteries has been around for several years now. The idea is to replace the cathode of the battery with atmospheric air, which is practically limitless. If we can do this, we may be able to have batteries with 10 times the storage capacity of those we have today. Tesla EVs average about 244 miles between charges; recently, an Aussie drove one a distance of 313 miles on a single charge, a world record for EVs. Using that as a yardstick, we can assume that using air battery technology and a battery of the same weight, it would be possible to drive from coast to coast in the USA without recharging. Impressive. If we did have such a great increase in storage capacity, of course, what would be far more practical would be to make cars with much smaller batteries-- say, 100 lbs. or so-- that would have a much smaller range, but they would be much cheaper, much lighter and nimbler, much quicker in acceleration, and would conserve resources much better. Other technologies are also capable of increasing a battery's energy density dramatically, and if used in conjunction with air battery technology we could conceivably have batteries weighing only 20 lbs. or so, and still giving us a very satisfying range between charges. Coating the anode with carbon nanotubes, for instance, has been claimed to also give a potential tenfold increase in energy storage-- imagine a Tesla with a battery using both technologies-- air battery and carbon nanotubes on the cathode-- that theoretically could increase range by a factor of 100, possibly giving a Tesla a theoretical driving range of 31,300 miles! The earth's circumference is about 24,800 miles, meaning that we could theoretically drive completely around the equator of the earth on a single charge! What would be much more practical, of course, is to make the battery only as big as we really need it to drive a comfortable distance... say, 200 miles or so... meaning the car could be extremely light with great acceleration. If the battery could be reduced in weight that much, so could all the rest of the drive train-- the electric motor, the electronic controller, drive shaft, axles, etc. A very powerful, inexpensive, lightweight, practical EV could still have a very good range. Realistically, batteries may never achieve such spectacular performance, but without doubt they'll get better, cheaper and smaller, and EVs will be able to fully replace ICE-powered cars even if lithium becomes a strategic material. Before we do, though, we need to install an aggressive material recycling program to recover as much as possible of the lithium and other rare elements we'll be using, so it is not squandered.

    Based on the Chevy Volt, Cadillac's Electric Converj Concept Could See Production

    By Posted on 11.10.2009 3 Comments

    With GM's Volt extended-range electric car set to arrive in dealerships by early next decade, some are asking whether US buyers will be switched off by a $40,000 Chevy. But would those buyers -- essentially early adopters of GM's new plug-in, gas-electric propulsion technology dubbed Voltec -- be more likely to plunk down such a wad of cash on a Caddy?

    @ ford2go: Touche! I'd like to see them get skewered on Dilbert as well, but more importantly, GM, Ford, and so many car makers still don't get it-- the EV-1 was and is very popular, and with no changes at all (just batteries of current chemistry would be nice) would satisfy millions of us. Hybrids are far more complex than the cars we have today, and that complexity only increases the likelihood that it will end up in a wrecking yard sooner than later. I won't let GM force-feed me vehicles that will consume our natural resources at an alarming rate. I'd much rather have a Nissan Leaf, Phoenix Motorcar, Fisker, Tesla S-- anything but another vehicle with an engine. To say that the engine will not be used often is no solution-- hybrids are still far more complex than the cars we have today, they'll require even more specialized and expensive maintenance and repair work, and these very expensive cars will end up in a landfill or a wrecking yard far too soon. Look at what has become of the Toyota RAV-4 EVs that are more than a decade old-- they have had virtually no maintenance or battery replacements in all these years despite heavy usage, and they continue to run well. Such a car as that could easily continue to run for dozens of years more so long as suspension parts, wheel bearings and other simple parts are available. No, GM-- I don't want your Cadillac hybrid. I want an EV as good as the EV-1 you already know how to make, something that will last longer than the hybrid you want to foist off on me.

    Video: Lockheed's Amazing Monocopter Drone Takes Flight

    By Jeremy Hsu Posted on 10.6.2009 9 Comments

    Drones have become big business for today's military, whether they come in the form of Hellfire-spitting Reapers and Predators or large airships that can hover over battlefields. Then, there's this small monocopter that flies like a maple seed pod.

    There have been several very asymmetric aircraft, my own favorite being the Blohm & Voss BV-141 of WW II Germany. It had a pod for the crew on the right, and a full fuselage on the left that held the engine, propeller and equally asymmetrical tail. The tail extending to the left of the fuselage, helping to balance the aerodynamic drag of the crew pod. The configuration was not capricious-- it had excellent visibility due to the lack of props and engines fore and aft of their cabin, making it rather ideal for reconnaissance. Its air handling was apparently not a problem-- its odd appearance was its only downfall, giving the plane little support among military higher-ups. I can imagine it would have been difficult to convince a crew to trust their lives to such an unconventional design.

    Does Commute: New Electric Three-Wheeler Electric Seats Two, Hits 75 mph

    You say you want an an electric car, but only have one friend and 30 grand burning a hole in your pocket? The Myers Motors NMG2 may be your cup of lithium. And you can even help name it.

    After seeing the anemic support the Bush administration showed for clean energy and clean cars, I'm elated to see Obama's commitment to Tesla, Fisker, and apparently Phoenix Motorcars, Aptera, and Meyers as well. If the new EV startups displace GM and the other Detroit dinosaurs, and they go into bankruptcy again and for the last time, it can only be their own fault for trying to force-feed us ICE (internal combustion engine) cars for so long. They should never have tried to sabotage their own EV-1 program and other viable electrics a decade ago. We need a robust, competitive, nimble EV industry that can drive out obsolescent old-school attitudes that have pervaded Detroit. If the Volt is as good as GM can do, they deserve to die out, and when its work force is laid off they can go to work for Tesla, Phoenix or other car makers that will give us what we really need. (BTW... for those that don't know, Phoenix will be emerging from bankruptcy in about 3 weeks ready to produce an EV with a platform that is distinct from its competition... stay tuned for details.)

    China Designs Indigenous UAV Stealth Fighter, and Bootlegs Some US Models

    By Posted on 10.15.2009 33 Comments

    When I hear the phrase "knock-off Chinese products", I usually think of either the bootleg DVDs I get on the subway or the cheap electronics I get in Midtown. But a new report in Defense Professionals notes that the Chinese military has channeled that same skill for replication towards closing their UAV technology gap. By simply copying US technology, China has created a stock of advanced drones, and gained the technical knowledge to create some interesting native UAVs as well.

    China Plans World's Largest Solar Power Plant

    By Susannah F. Locke Posted on 9.8.2009 16 Comments

    First Solar just signed an agreement with China to build the biggest solar power plant yet, according to a statement released today by the company. The 2-gigawatt plant in the Mongolian desert will generate enough electricity to power three million homes. That's a heck of a lot of cadmium telluride, the semiconductor they use for their thin film cells.

    . TechnoFreakFace: Your smugness, arrogance, and misplaced confidence are amazing. The (heavily subsidized) nuclear power plants that were decommissioned decades ago are still causing us problems and still costing us billions trying to find storage for steadily accumulating nuclear waste. No one wants a nuclear power plant or radioactive waste in THEIR back yard-- you're such a pious nuclear proponent, here's a thought: what's your address? We'll send it to YOUR house, and they can store all their spent fuel in YOUR basement. Oh... I hope your basement is really, really big-- they've got a lot of it for you to store for them for the next 15,000 years or so. Nuclear plants have problems solar will never have-- you'll never have problems with terrorists trying to steal solar waste for dirty bombs or trying to blow up the plants to trigger environmental disasters. They have no earthquake hazards, there's no wasting billions of dollars doing environmental reports trying to convince nervous neighbors that your plant won't become another Chernobyl, no worries how you'll decommission your solar plant and keep it safe for thousands of years for future earthlings. If I make solar cells, my kids could brag about it to their friends-- if you make nuclear power plants, your kids might wanna say you're really a plumber just cuz they don't wanna be ostracized by their peers. Solar has no problems that will haunt our children's children-- it's not a perfect technology, but don't dare try to point out its problems, because in every way it's a more benign power solution than anything else with the possible exception of wind. Solar is still in its infancy, and the more we deploy it, the more efficient it will become and the more ubiquitous it will be. 233 watts of power fall on every square foot of noontime earth surface, and all we need to do is pump up the efficiency marginally to make it the most cost-effective way to generate power. Nanocrystalline-based solar cells, quantum dots, Schottky barrier/junctions and other strategies that increase efficiency could one day be combined in a mass-produced printing process to yield efficiencies far in excess of anything we have today. And with proven technology such as Altair NanoSafe batteries that can last for tens of thousands of charge cycles-- decades or more of use-- we will be able to store that power for use at night or whenever we need it. Whenever I see such skewed comments as yours, I have to wonder-- do you work for the nuclear industry, perhaps? What axe do you have to grind that you would seek to steer anyone away from such clean technologies as solar and EVs?

    Google Working on "Smart Charging" Software for Electric Cars

    By Mike Spinelli Posted on 10.7.2009 9 Comments

    Imagine millions of plug-in vehicle owners returning home from work on a hot summer day, plugging in their cars at the same time, and melting down an overtaxed, outdated, and otherwise atrophied electrical grid. But the geniuses at Google say averting a disaster scenario could be as simple as a few lines of code (well, a few more than just a few).

    10.18.2009 at 04:32pm - Comment by billdale

    In the past, electricity was a pretty simple thing, whether you're talking about generating stations, the grid, our appliances, or radios and flashlights. As time goes on, everything about electricity will be much more complex-- expect that part of the solution of future power will be a process of the best solutions surviving and flourishing, and promising ideas with hidden flaws will fade away. As things shake out, there will still be a grid, but I expect it to be supplemented in large measure by lots of solar and wind-- in urban areas, solar will be ubiquitous, with panels on nearly everything. Single-family homes, garages, apartment buildings, office buildings and factories will all be generating power, and with nanodots and other new tools to make solar more and more efficient, we won't be thinking of the grid as our prime source of power, it will become little more than a backup. Wind power may become the power source of choice for rural use. Urban and suburban EV charging stations will be receiving the bulk of their energy from the roofs of local businesses and residences, and decentralized charge reservoirs, especially in homes and public EV stations, will make blackouts and power shortages far less likely. Charging will be available wherever you park-- the supermarket, school, theater, church-- so moving about in our lives will be more convenient and affordable than it's ever been.

    Report: Tesla Model S Designed for Battery Swapping

    By Mike Spinelli Posted on 9.28.2009 16 Comments

    Imagine pulling into a service station, but instead of filling the tank with unleaded, you slide out your drained battery and -- for a fee -- slide in a fully charged one. It's a similar model to that many stores use for propane tanks, and it could one envisioned for Tesla's new Model S sedan. Edmunds Green Car Advisor reports the new model was designed with swappable batteries in mind, according to Tesla's outgoing director of vehicle engineering and manufacturing.

    neonrobot and bigb: !!!! Don't let anybody shut you up! It's not the grumps of the world that count, it's the ones that take you seriously, and you can be sure there are plenty of older people-- such as myself-- that will always be willing to hear what you have to say. When I was 12 I started reading Popular Science and Popular Mechanics magazines just like you guys, getting creative, and eventually building the things I imagined. I recently converted a BMW coupe to full electric power that is much faster than it was when it was running on gasoline, and is "burning rubber" now on You Tube. It was much more difficult, it took much longer and cost much more than I expected, but the car's getting plenty of attention and I'm using it to help people get the idea that EVs are the logical replacement for gasoline cars. Keep going, fellas. We need smart, creative guys like you to provide the inventions we'll be using in the years ahead. Battery swapping may prevail, or it may not, but in any case you'll find some of your ideas work and some won't. Don't allow your failures to define who you are, allow your persistence to do so. If you try a hundred different ideas and only one of them works, but that one idea is a cure for cancer or helps us to get into space cheaply and safely, it's your successes that you'll be remembered for.
