    It good your digging into the data. Look at the footnote 3 on that table. Costs are expressed based on energy delivered to the grid, not raw Watt ratings. And variable costs are costs based on variation in production. PV maintainance is basically the same no matter how much or little the sun shines. (clean once a weak, replace failed panels).

    As for transmission cost, it includes upgrades and extensions to the gird, as utility-scale PV and wind are located far away from consumption centers. A lot of times I see wind farm locations being considered because a new line has been installed. At work we joke we're chasing that same damn power line across the country. It's still a cost though, but may or may not be internalized to the final wholesale price.

    Your source is two years old. https://www.eia.gov/outlooks/a... The cost of solar PV is rapidly decreasing, while advance nuclear projections are nearly static, and the only current nuclear construction project has gone way over budget. Right now storage is mostly infeasible, but long distance transmission lines are quite feasible and being built at a fast pace. If the sun isn't shinning where you are, the wind might be blowing strong two states over.

    So yes, all solar and wind is silly given current tech and prices, but "a good bit more" is not, especially compared to currently approved nuclear designs.

    You also get regenerative braking essentially for free with an electric car. A reasonably effecient electric car with consume 15 kW*hrs per 100 km.

    But for most people to charge their car from solar, you'd need a battery bank at home and lose a lot of efficiency there. If you have solar, you're better off sending excess to the grid an charging the car at night during off-peak hours. Right now if a household has more than one car, having one on them electric is not going to be too much of a pain to manage.

    Comparing MW*hr to MW*hr, wind and solar are the cheapest option out there right now to adding capacity to the grid. Yes storage and timing is an issue, but a well planned system could use solar/wind to supplement during peak demand. Right now base-load at EOL should shift to natural gas, and anything more than 5 years out should seriously signal a willingness to use 4th gen nuclear designs.

    If the "bundle" constitutes a derrivative work ,as is quite likely the case when you distribute binary modules pre-installed (linked to the rest of the kernel), then the GPL requires you to release source for the whole work (under a GPL licence) or refrain from distributing the modified work.

    And I don't want this to be a license war, the software project should pick the license that is right for thier own goals. However, so long as copyright is enforceable we should expect commercial project to follow them scrupulously.

    >"Depression is caused by basically the receptors for "feeling good" failing to activate, either by not having enough of them, "

    The problem with this theory is that there exists not objective test to validate the theory. Depression of the DSM manual is only diagnosed behaviorally. If depression really were a physical problem with the brain, shouldn't there be a physical/chemical test to confirm diagnoses?

    This assumes P != NP, an unproven assumption. Instead of merely guessing a private key, crypto-analysis involves looking at data streams and deterministic transformations. It may actually be the case that all cyrpto schemes can be reversed in polynomial time via algebraic transformation. This technique as definitely been used to decrease the actual effective key length of many crypto schemes.
