The company I work for attends a trade show every year that costs much less to attend than CES (at least I assume so). We pay on the order of $50,000 for the show space for 2.5 days worth. That's JUST for the space. We've invested, over the years, probably about another $200,000 worth of time, product, and show equipment. We have five highly paid engineers at the show for about five days, where we can't get any work done at the office. That's about another $10,000 and hotel, food, and flight reservations for about another $5,000. You're already sitting at around $300,000 before one customer comes to the booth to even LOOK at our stuff. And we're a small company at a small show. A big show like CES and a big company like the ones that had their TVs shut off...wow.
I've been using 240V / 250W bulbs in my house for a while now. The filament life is related to the how hot it gets and for how long it is on. 250W bulbs have a MUCH larger filament than 60W bulbs because they're supposed to get brighter. If you run a 240V bulb at 120V, you get out about 1/4 of the wattage, making that 250W bulb look like 50W and also lasting at least four times as long.
Much of the shock hazard is dependent on the amount of current available. On a standard 110VAC outlet, you may have 15A or 20A available. On a 110VDC battery bank, you'd have hundreds of amps available. I'll take the AC shock over the DC shock any day.
It is nearly impossible to extinquish a fault on a DC line because the voltage never reaches a zero point. Protection devices on AC lines rely upon the zero point to extinquish faults.
Actually, it is easier to extinguish because of the current zero. When the current wave hits zero, the arc briefly goes out. This is why DC is so difficult to break, the current never hits zero. Almost all "advanced" switching devices look at the current wave and will switch when the current is zero, causing almost no damage to the switch contacts.
Wow, charging the batteries in one minute? I'm not sure about lithium batteries, but standard lead acid batteries have a recommended maximum charge rate. For them to recharge the battery in one minute, they're going to have to be pushing a LOT of current...especially considering they're going 15km on one charge. I'd be worried about battery life on these (probably) expensive batteries.
you can only record one channel at a time, your recordings will have cable-box banners all over them
With my Comcast cable box, I can record two channels at once. The only thing is that I have to watch one of those two channels. I can happily record one channel and watch a different channel all I want.
None of my recording say anything about Comcast on them. They're plain recordings. Now, the menu system has Comcast crap all over it...
On my roomies computer, so the damn XP rig would actually work again.
With all due respect, if you're smart about how you surf...you won't have to run a virus scan. I haven't had a virus scanner on my XP machine in five years and I haven't gotten a virus yet. Think about something before you click on it. Don't be a random internet user and you don't get crap on your computer.
I'm not sure what types of batteries they were using, but standard lead-acid batteries vent hydrogen during charging. If you don't make provisions for the removal of it and it builds up in the cabinet, one tiny spark and you've got yourself a little bomb sitting there.

I've found no more true statment in my years in engineering.
I can begin to estimate the cost:

If these are large batteries with many AH, how big of a power supply would you need to charge 90% of the battery in ten minutes?

I was trying to figure out how they would make a "Solid-State" capacitor...
Get yourself an MVS cabinet. I have Samurai Shodown 1-4 in my dual game cabinet. Total cost: $500.
