You are correct. Hydrogen is a method of storing energy, not generating it. Nuke plants are great for producing hydrogen, but any power source can be technically used to do it. I'm not sure that any of the "renewable" sources listed above lends itself to such as well as nuke does, or significantly better than the others.

CowboyNeal is my passport. Verify me.

I love the irony here. Icebrain is asking what snow is, so I can actually say "it's a powdered version of what you have inside your head."

In the US, they are also deductible. Essentially, you subtract the interest you pay on your home from your income. Assuming a 50% tax rate, your 6% home interest rate is costing you only 3% in spendable dollars (not counting principal).
Some people stop there. You have to look at it from the other side though. For every $1.00 you give the bank, the government gives you back $.50. Some people think this is a good idea, even if they could stop paying the interest at all. I haven't figured out why.

Even on a paid-off house, you still have property tax, house insurance, maintenance costs (repairs, lawn care, snow removal...)
Yes, the maintenance costs generally go down if you DIY, but you're still spending time, and that's a cost too. You can also not carry insurance (if you have no mortgage) but that increases the risk of some serious maintenance costs in the event of fire, break-in, etc.
Housing is never really free. Even living in your parents' basement, you've got some form of cost, even if not financial. (Sanity? That's what you get in your shoes when you walk on a beach, right?)

This is what I do too. Homebrew hardware running Debian, with 4 drives in a RAID5 configuration running EXT3, shared over the gigabit network using Samba. Bottleneck is the laptop hard drive. It works great, and I can afford to have a single drive fail with no data loss. I mainly use it to back up hard drives and to store media files (movies and music.) The server also doubles as the network's router, but that's irrelevant to this discussion.

Sounds like a valid durability test for a SD card. I'd be willing to bet that it would survive longer in the pan than the bird would.

Audit trails are automatically generated, and can often be found on logs and cable trays.

Just wait 'til you get out into the real world. There are tons of them out here! (And not in the weigh-a-ton sense that many Engineering school women fit.)

My servers and workstations increment through the alphabet.
Addled
Burnout
Clueless
Dimension
Eptitude...
Last octet of the static IP is based on the position in the alphabet of each hostname and the NIC number in the system (Addled = .10, Burnout = .20 and .21 etc) regardless of which subnet that NIC resides on. When a system is retired, so is the name. Using this method I can get a pretty good idea of how old a system is in relation to the others. This scheme only works in a very small environment.
My suggestion is thus:
1-25 workstations: be creative. Use names that you can remember.
25-100 workstations: create groups of rooms or departments based on themes, and be creative within the themes. Tag hostnames on cases.
100+ workstations: use an asset-tag type scheme, possibly including location (campus-level, not cube-level) information that won't change, and perhaps user. Tag hostnames on cases. Reimage and rename systems when repurposing. Use a database to track specifics of the systems.
