    20% reclamation of the 60% energy wasted as heat is 12% extra efficiency. If that 12% is worth only $80, that means that 100% of annual gasoline expenses is only $670. At $4 a gallon (which is 2008's average, not 2013's), that's 166.7 gallons, which at 35MPG is 5833 miles. 500 miles a month.

    Something's wrong with your math. Average annual mileage is at least double that.

    Besides, there are other costs for the lower mileage. More frequent fillup stops/trips. Environmental damage.

    People will pay more than $500 more for a car to get 33.6 instead of 30MPG, even if they don't save as much in gas expenses while they own the car.

    The scientists say they'll have a product on the market in something like 3-4 years. Which, since they're working under the Ohio State patent office, means they're probably close to producing the product itself, and are just talking about patent and licensing time. The zT:1.5 material isn't a very competitive product, at 10% efficiency, to enter the very conservative automobile market with its new technology and approach. I expect that they expect to market the zT:3 material, with its 21% efficiency in the car engine operating range.

    A device made from this stuff wouldn't be complex at all, about as complex as a catalytic converter, and possibly combined with one (or just a "premuffler"). The electricity it uses would be useful right away for all the car's accessories other than driving the wheels. Hybrids could use it directly for motive power. And within 5 years, regenerative brakes will likely be standard on many models, with the electricity used inside the car already.

    Oh, and $4 a gallon is already disappearing in the rearview mirror. $10:gal gasoline makes all those other changes closer than they appear.

    Thanks for the offer. I've already got my own management software / scripts. But if VMWare (or other virt SW) could do it, integrated with its other process management and installation features, that would be a reason to look again at VMWare. Especially since a common environment instead of my own idiosyncratic scripts for this completely universal task would be a good evolution of the biz. So I'll look at Canonical's projects. Thanks.

    "Frankly", what you jsut said is stupid, poorly thought out, and has everything to do with catering to corporate interests and negative impact on customers.

    The telecom industry is a cartel. That is why its rates are controlled by the government. Landline phones are the worst: there's practically no competition in any one place, and between Sprint, Verizon and AT&T that's practically every landline. Who routinely collude on all kinds of rates.

    I own a small telephone company that interconnects the major long distance networks. There are really only about 8 of those, even though they do compete geographically. They always coordinate their pricing and marketing to first ensure they keep out any new competitors, then ensure they equally exploit their own customers, and finally, if there's any opportunity left, to fight viciously for each other's customers.

    Cablecos have even less competition with each other in any one place. And their bundling is even tighter, without even a difference between the "local" and "long distance" networks they operate as vertical monopolies.

    There is also very little competition between telcos and cablecos, wherever they can compete for the same customer.

    The government's role in the market is keeping it free of monopolies and cartels. The FCC, as friendly as it is to monopolies and cartels (as a Bush crony regime agency, that's its ideology), has quite a lot of work keeping the balance between cartels and the market sustainable. Part of that protection is ensuring that the telcos reinvest in what's mutually beneficial for the market and the telcos. Which research (including internal, by telcos, as I found when I helped the NY City Council produce a "Net Neutrality" hearing) shows is to build more capacity, not to create content tiers. Instead, telcos are trying to control traffic based on its content, so that they can compete unfairly with new competitive entrants to their markets that they want to keep out, or crush where they've already found niches (eg. Vonage).

    What am I "proposing"? I just called out the cranks like McDowell who say that requiring equal access to WANs is somehow "handcuffing the engineers", when it's just stopping executives from continuing to game the system, which is always their first choice.

    I'm talking as someone who runs a telco, and who has advised the NYC legislature on telecom for over 5 years, with real facts and market logic taken from real history. You are talking as some kind of ideological Republican. Er, I mean "libertarian" (that old brand doesn't fool anyone anymore).

    No, what I want is an environment that is actually 3 separate servers, but with all their configs on each synchronized, so the environment is identical.

    Current zT:0.87 can get about 6% efficiency; these new materials at zT:1.5 get about 10%; their forecast zT:3 materials will get about 21%, in engines like in our cars. I don't know where you're getting that 3% efficient heat recovery figure from.

    Every mechanical process could benefit from recovering significant amounts of heat. Most heat engines, especially gasoline/diesel types, include extra machinery for exhausting heat which could be replaced with probably simpler devices that are like "catalytic converters" capturing the heat instead of exhausting it. Even the windmills and other turbines you prefer would benefit from the increased efficiency: everything would.

    The question with a device like a heat reclaimer is whether the energy it captures during its lifetime is greater than the energy it costs to make, deploy and recycle it. Since these devices are said to last a long time, decades perhaps, they probably can pay for their supper. And in constant-duty machines like windmills, they're probably a faster payback than in cars that run for only about 5% of their calendar lifetimes.

    We need to use everything we've got to get past the energy/Greenhouse crisis already upon us. We're never going to not care about efficiency, especially as we power ever smaller devices, more mobile and independent of a wired infrastructure.

If it were made of this stuff, that could mean quite a lot of power. Especially in remote locations, a combination of wind/solar/geothermal with storage could add a geothermal "trickle charge" to the statistical average wind/solar recharge blasts, and guarantee full power at constant duty.
