haven't worked out the kinks yet on modern animals. Only 22 species have been cloned with 19 species able to result in an adult.

So, in spite of the thought its a common and easy thing to do, its not.

The next issue is economics. If you were to choose an animal to clone would it be an animal that is broadly useful to human kind and have a return on investment to pay for the costs of development, or would you choose an animal that is expensive to keep and a great public interest as a curiosity, but won't solve an important problem or make enough money (even in zoo ticket sales)?

P.S. Don't tell me the economics of tourism and ticket sales for views will pay for the cost of cloning a DoDo....its still more valuable to clone a mundane animal like a super cow that produces lots of milk and/or meat.

The "use a printer at home" threw me for a bit, as clearly everyone on occasion has to print something out, even if its rarely.

People below 65 do it at work. Older people don't have the luxury of stealing office supplies from their work

I'd like to see the advantages of a hydrogen energy storage system over conventional battery storage systems.

Hydrogen as energy storage lacks energy density, and suffers some serious safety issues (very high pressure flammable gas). Conventional batteries are heavy, take longer to recharge, but have much higher energy density.

This assumes there was consistent and real conflict between the two populations.

another example of the meaning of words changing over time.

It means one specific thing to her.....and something completely different to you.

Call her a 'Dork' and watch her mind explode.

"Leaked"

what host 'needs' to survive? The host just needs to live long enough to pass the virus along.

Yes, I agree. Hydrogen can be used in combustion engines, but practically it is not, Its much less efficient. I disagree that burning hydrogen is 'suitable' for powering large vehicles because of its lack of energy content per mass. Any research are hydrogen powered aircraft are using it to generate electricity, not to burn it directly. The bigger problem there is storing enough hydrogen under pressure to make a practical difference.

Even if I'm wrong, and burning hydrogen becomes more practical in applications rather than in fuel cells, the fact still remains that you have to somehow put energy into the system first to get your hydrogen. Its still energy 'storage' rather than creation.

The nerd in me wants you to graph them against each other with a regression line to see how they might correlate

Have to always keep in mind that hydrogen is an energy storage system; not an energy source. It functions as a battery. If a hydrogen fuel cell is better in some respect than other battery types than we can improve our lot.

It, however, always requires energy from somewhere else to create the hydrogen for the fuel. That original energy could be solar or wind or anything else.

It was years before the story was written......not years before it happened.

You're undead, Harry.

I do want to comment that killing in the name of religious belief is what really bothers me. Its not that communism, or fascism involves a god....but it involves commitment to an ideology with religious fervor in the righteousness of the cause.

I don't think a believer in god is inherently a large cause for killing, but religious devotion to an ideology is.
