Bio-Tech: Uses and Abuses

Ghost, remember...

I USED TO BE A GENETICIST!!

oh, wait, most of you weren't around back then. I worked on the human genome project and detection systems (CSI uses a lot of my old job's products) afterward.

yes, I'm reel ejukated.
 
I would make a clone army....of me. OMG I would be unstopable, but I know my army of me's would turn on themselves...because I am untrustworthy...which would eventualy start a civil war...ehh it would be interesting watching me kill myself by the hundreds.
 
everything should run off of alcohol. It burns cleaner, is replenishable (and we pay farmers not to grow stuff, so get out the John Deere, farmer Brown!), and my family deals in moonshine (I recently discovered an uncle's still).
 
You know: we could be using our poop to power our homes. There is technology out there that converts the methane produced by poop into electricity (I think without burning it, but I'm not sure of that). Nothing that I know of on the market, though, which is too bad, cause I'd do it. Power your home for the price of your groceries.

There's some question as to the input vs. output of alcohol as a fuel. Some research is saying that the BTU's required to produce a gallon of alchohol-based fuel is greater than the amount of BTU's that gallon generates. This would mena it's non-sustainable.

I like the technology behind hydrogen fuel cells, but I don't like the application right now. Basically, a hydrogen fuel call can be used as a battery. If we were to have more solar and wind energy collection, we could use that power to "charge" the hydrogen fuel cell "batteries" and use them for all kinds of things, from cars to toasters to... um... more toasters.
 
I didn't think you could charge a fuel cell with simple electricity. I thought you needed to fill'er up with H2 again. You have "" around "charge" so you might have meant something more complex, though. If so, could you net it out? I'm interested.
 
No matter how you have to "refill" a fuel cell, it will take energy to do so. There are several different types of fuel cell, but the hydrogen used in hydrogen fuel cells is not quite the same thing as thehydrogen that's floating around in the air we breathe. To make it usable for a fuel cell, it has to be processed, and that processing takes energy.

As we all know, you can never get more energy out of a system than you put in. Following that backwards, if we get energy out of a fuel cell, we must put energy in. In that way, they are very much like a rechargeable battery.

Most current plans use our current energy infrastructure to provide the base energy input into the fuel cell "system". That infrastructure relies mainly on oil and coal burning power plants. This, in the case of, cor example, cars, all we're doing is removing emissions from the tailpipe to the smokestack. The energy has to come from somewhere, after all. The way to make it a truly sustainable, renewable system is to use renewable resources such as solar or wind power.

Yes, this is a simplified explanation, but i don't really have the space or inclination to copy and paste all of the relevant details. I don't know how familiar you are with the technology but, as always, howstuffworks.com is a great place to start.
