    What can't Toyota periodically replace sections where the plants are? $Counter = 0; 1). Cut down section of plants 2). Bury plants to trap chemicals just like a bog would 3). plant new plants in cleared section 4). $Counter++ 5). If $Counter >= 10,000 then recover coal/oil, $counter = 0 6). Goto line 1

    Because Toyota is primarily a car company, not a TDP company. If they were experts at the esoteric art of TDP they would probably operate a TDP plant instead of making cars, but since they are experts at making the world's best cars, they make cars instead, along with occasional PR filler material like the article.

    Also, its unclear if even the TDP experts can run a TDP plant at a profit, but Toyota has a track record of running a car company at a profit ... so do what makes the money ...

    How much of that cost is the cable?

    http://www.isp-planet.com/business/fiber_price_bol.html

    On land rural jobs cost about $15K/mile. On land super-urban jobs cost about $500K/mile. The difference is permits, corruption, kickbacks, etc. Also scaling is important, "one job in Montana" may be hundreds of miles, and "one job in Manhatten" may be measured in feet, but the fixed costs are... fixed... so the cost per mile seems higher on the short jobs.

    If you assume underwater fiber costs around as much as the total cost of cheap rural route, the 6200 mile route times 16K/mile equals about $100M. That makes sense, since the whole job is only supposed to cost about $300M.

    Repairing fiber is somewhat more difficult than laying fiber because it's time sensitive. But then again they probably charge by the hour anyway. Since a "several day" repair job approaches $10M, if you assume that is 4 days at $10M total, that would be about $2.5M per day. The little row boat they're using is going to take about 40 days to paddle across the pond, 40 days * $2.5M a day conveniently works out to about $100M. That makes sense, since the whole job is only supposed to cost about $300M.

    Add in the usual admin overhead, several multimillion dollar executive bonuses, engineering work, station gear at each endpoint, marketing and sales upfront expenses including slashvertisements, booze, coke, etc, I think they could blow somewhat less than $100M on that.

    My labor estimate is probably about right for overtime repair work and a bit high for contracted construction work. My estimate for overhead may be a bit high. That means the cost of the cable itself probably is about $125M to $150M.

    What do you mean by sacrificing power? Regenerative braking returns some of the vehicle's kinetic energy to the battery, making the car more efficient.

    Think slamming it in reverse at full throttle instantaneously, up to and including breaking the tires loose and smoking them. With current technology (electric "current" get it?) that would probably roast the controller and the motor.

    I know you're just trolling, but its an interesting topic anyway.

    Most conversion stories seem to begin with "remove burned out IC engine and leaky transmission". You'd be surprised how expensive a new gas drivetrain plus installation costs compared to the new parts for a small electric drivetrain. So, drivetrain is usually mentally justified as a repair cost.

    Then justify the purchase price of just enough small lead acid deep cycle batteries to just barely work, because you've got leftover money from the drivetrain, and you'll never pay for gas again, even if it barely makes it to the grocery store and back. So, first tiny battery set is usually mentally justified as an investment with a great ROI (not buying gas).

    Once it works pretty well, justify more paralleled batteries for longer range, because its a luxury and you're worth it and just for the pure heck of it, etc etc. Just like you don't "need" leather seats but you wasted the money on them anyway, you can waste the money on 100 miles worth of battery that you don't need if you really want it. Plus you can one-up the guy you saw on the internet and who cares what it costs, you're going to out do his conversion no matter the expense. So, second set of batteries is usually mentally justified as a pure luxury.

Megawatt class cables are not little old lady friendly. 0000 gauge wire is a roughly half inch diameter solid bar of copper, weighs about a pound per foot, rated to only 200 amps at insulation temperature delta high enough to burn hands on a summer day. At 200 amps, you need a mere 5 KV to pass a megawatt. You could use bigger cables, but making the "power cable" weigh over 50 pounds is not granny friendly, and the induced voltage from that current will zap grannies pacemaker. Or you could trade off for higher voltage, but I don't think UL will list "consumer accessible" stuff above 477 volts and on a rainy day the connector will have to be quite large just to survive a mere 5 KV without arcing over. Assuming the connectors insulator is perfectly clean of course.

    Yeah sense of awe, as in WTF... the skylon is unrealistic for the following reasons:

    1) Looking at the wikipedia article, first off, 50% faster than blackbird engines is a pure pipe dream. Material science has not improved enough for turbine blades to survive that, and the intakes required to decelerate incoming air to subsonic will either be too heavy, or impossible, or not distribute airflow evenly enough, etc etc. Tech and cad design help some, but not enough.
