Q: Bill Jeffers - Where can I get a cheap bubble hockey table?
A: There are many locations on the internets that offer bubble hockey tables. Your definition of the word "cheap" dictates which of them to choose. Below is a quick and dirty list:
In addition, I'd suggest looking at places like craigslist.com and ebay.
Q: Karyn Graves - Does the technology exist for the production of vehicles (that can hold more than 1 person) and can get at least 70mpg (electric/diesel/whatever)? How long will it be before they are mass produced and people actually buy them?
A: Let me be the first to say that I am by no means qualified to answer this question. Actually, I'm not really qualified to answer most of the questions I get, but I'll give this one some thought.
I suspect that the answer to your first question is yes. Automotive companies put millions of dollars into research every year. I expect that there are some fancy engines under development that can push fuel economies to new and uncharted heights. But if that's the case, then why haven't these technologies made their way onto our driveways? I suspect that the answer is that the cost of these technologies outweighs the benefits. Sure, you can have a car that gets 100mpg, but if it costs $200,000, who wants it?
As to the question of when these technologies (assuming they exist) will become available, I think the answer is "as soon as they're ready". I'm not someone who thinks that there is some grand conspiracy between oil companies and car manufacturers. It just doesn't make sense to me. If a car company had the technology to make a car that could get 100mpg and cost roughly the same as an existing car, they would release it, and it would sell like hotcakes.
Sorry this answer is fairly incomplete. I'll give it some more thought, and if I come up with anything else I'll post an addendum.
