What electricity? The batteries are charged by the gas engine.
Note that pollution from an electric plant would be less if you did charge your batteries from the grid, as large plants allow economies of scale in pollution reduction.
Lead acid batteries, which I think are what are used in most hybrids, are the most recycled commodity in the country. Over 95% recycled. Into more batteries even (i.e. not down-cycled). All the infrastructure is already in place.
The article seems to be assuming that Gas prices remain constant through the life of a car. Anyone believe that? How about the same calculations assuming a 10% per year increase in gas prices (which they were this year before Katrina).
I have large removable baseboards. I could rewire my entire house without ANY construction. My sister had one leaky pipe in her 'standard construction' house, and no she has two huge holes in her living room ceiling.
To the original poster: Think about vertical as well as horizontal chases. Don't put ANYTHING where you can't get to it. Reduce as much as you can exterior wall penetrations.
Get used to the three little pigs jokes. Everyone thinks they are the first to think of it...
Given the severe economic and safety problems shutting down the GPS system would cause, telling terrorists that you will do it, gives them another weapon. With little risk, they could make threats to cause such a shut down. Repeatedly.
It might stop spammers. At the very least it will slow them down. Remember that they need YOUR public key to send you encrypted mail. They don't actually need one of their own. So, instead of just getting your email from a list, they need to get your public key too, and then encrypt the message (a slow process if you are sending millions of e-mails), separately for each recipient.
There is close to zero chance that a spammer would go through the trouble until ALL email is encrypted.
it was arrogant to think man could tame fire. It was arrogant to think man could harness the wind. It was arrogant to think man could tame animals. It was arrogant to think man could cultivate crops. . . It was arrogant to think man could fly. It was arrogant to think man could cause mass extinctions. It was arrogant to think man could affect the speed of the spin of the earth (through keeping water in reservoirs). It was arrogant to think man could go to the moon.
These things have been done. Why is this next arrogant thing therefore impossible?
More to the point, environmentalists would no doubt be happy if nothing is done. Unfortunately, we are busy doing something, namely dumping billions of tons of CO2 into the atmosphere (at an increasing rate). Inaction would be a vast improvement.
If 'rocket scientists' can't figure out what to do with fuel for a air purification systems, we will never get our butts off this rock.
Seriously, where is the composting and greywater system, with the compost growing plants to convert CO2 into O2. It seems to me that this is the FIRST thing that should be worked out. Without it, space travel is just a HUGE drain on planet-side resources. With it, we are on our way to the stars.

Good Luck.

Announcing this just made us all less safe.
Thank You Kindly.

$260 million is $1 per US citizen. A bargain if ever there was one. I suspect that this estimate is extremely low.
The hard part is, of course, proofreading. See distributed proofreading at http://www.pgdp.net/c/default.php
Let's get started on the out-of-copyright stuff NOW. Maybe b the time is online, people will see the benefit of making everything available.
Thank You Kindly.
