      Car batteries are sealed and doesn't get refilled often.

      Those statements are incorrect and correct, in that order.

      Actually SOME car batteries ARE sealed. The ones whose insides look like modeling clay laid out smooth on tinfoil and wrapped up are sealed. They don't outgas and they can be mounted inside the vehicle, upside down, et cetera.

      But the vast majority of vehicles do not have that kind of battery. I don't think I've even heard of them being OE in any vehicle. Most vehicles have batteries that contain plates of lead suspended in sulfuric acid. IIRC there's a lead phosphate coating on the lead plates. during the chemical reaction the sulfur is extracted from the sulfuric acid, various reactions occur (sorry, I am not a chemist) and the lead phosphate is converted to lead sulfate. In the process hydrogen gas is released. When the battery is charged, the process works in reverse, drawing in air. So the batteries are most absolutely not sealed units. They vent. They must be stored, transported, and installed only in an upright position.

      The batteries don't get refilled often because the composition of the lead plates has changed over time; the chemicals involved have tended to remain the same but the way the plates are constructed have changed. The process is now more predictable and reliable and you don't tend to have batteries spooging liquid out of their vent holes, just releasing gas.

      For the record, anyone who DOES have a battery that permits maintenance ought to check it every year or so. If fluid is low in any cell, add distilled water to bring it up to the proper level. Never add sulfuric acid unless you actually test the acid mixture and discover that it is not correct. They sell little handheld testers with plastic balls that float in the liquid very cheaply at any reputable auto parts store.

The spent fuel is biodegradeable so you can dump it in the sewer. Refueling would probably end up being infrastructurally similar to current oil-based fuel distribution in order to ensure reliable deliverey and the proper sugar/enzyme mix.

      Even if the enzyme reaction takes a little time to get going and build up a proper charge, having multiple batteries running in an asynchronous parallel setup instead of serially should keep people moving. When battery A dies, the car switches to battery B and the "low fuel" light comes on.

Sure, that number often has little to do with the actual cost of making said product, but that's why trade is so nifty, someone with a lot of potatoes and no salt is willing to trade quite a few potatoes for some salt, and someone with a lot of salt and no potatoes is willing to trade quite a bit of salt for some potatoes, and they both walk away thinking about what a deal they got, especially when potato guy is good and growing potatoes and salt guy is good at mining salt. Your 'require' is simply a euphemism for placing a very high value on the product(i.e., if you require it, you are made so much better off by it that it is, in fact, 'worth' acquiring, even at seemingly obscene prices).

      In my mind, if a profit can be turned without a subsidy or tariff, that makes the subsidy or tariff more stupid. We simply have different estimations about the costs and benefits of securing some chunk of the fuel supply. I don't see a great deal of benefit from slowing the flow of money to the Middle East, which is presumably the chief benefit of home grown energy. We might reduce the amount of Middle East oil we use, but then we have to stop doing business with China, because they will buy the cheapest (transport) energy they can get their hands on, which, if we stop buying it, will be Middle East oil.

      The PS3 is a great example of what happens when the cost of a product exceeds its worth; it languishes on the shelves.

      if profit can be turned without a subsidy or tariff, that makes the subsidy or tariff more stupid.

      Ok, I'll separate it for you. Without the tariff, there is no incentive not to buy ethanol (made from Sugar) from Brazil. With it there is one. That incentive helps start a process which over time refines processing and reduces cost, in the end making it competitive with Brazil when the tariff is lifted. Opening a processing plant is a rather large investment. If Brazil wanted to bottom the cost of its ethanol substantially to increase its market share, it could make that initial investment seem foolish and that perceived danger is exactly what stops the private sector from investing in it. Subsidies offer a guaranteed bottom price with which you can calculate return on investment at a worst case scenario. Remember it is the Government's stated goal to reduce the dependence on foreign fuel for transportation. Do you have a non "stupid" idea that the government has not been alerted to, I'm sure they would love to hear it. They have decided to bet on many horses to help solve the problem. Hybrid and Electric Vehicle tax breaks and credits, Flex Fuel initiatives and Fuel efficiency standards, R&D, Loans, as well as subsidies and tariffs.

      This is interesting for the bio-tech field, but completely impractical for consumer electronics. The simple fact is, the human body, and consumer electronics have two very different needs in terms of energy. This is kind of like the NASA guys sitting around and saying, well, my car runs just fine on regular unleaded, why can't we just pump some of that into the shuttles tanks, it should work just as well. If they really really worked at it, they might even figure out a way to get the shuttle into orbit using regular unleaded, but the point is WHY! The liquid and solid fuels the shuttle uses are designed specificly for propelling the shuttle into orbit, and the unleaded fuels we put in our cars are designed to power our cars engines. I'm not saying that there arn't better fuel sources for either one, just that they arn't really interchangable. Just because one fuel source works well in one application, is no reason to try and use it in a completely different application.

      Sugars are an ok source of energy for the human body, they're relativly easy to come by in nature, and we can break them down without to much effort, thus we evolved to use them, but relative to other chemical reactions, sugars are not very energy dense. Now, for powering things like nano-bots or for alternative energy sources for implants, this is very interesting. Perhaps even for use in building bio-electronics it's useful as well, but to power normal electronics using sugars is just plain stupid.

    Not a problem. There isn't any shortage of food. Think about it. Here in the US, even with the BS of the government meddling in the marketplace with subsidies, tariffs and paying other people NOT to grow stuff the US not only grows enough to make us all obese we export a lot of food. Same in most other civilized nations with the exception of a couple of very dense populations such as Japan. So why are people starving?

    Lack of civilization and liberty. In North Korea they starve while across the DMZ life is good. Cuba can barely feed itself where it used to export. All it took was one asshat in Zimbabwe [sp?] (and a few million idiots to put him in power) to turn a nation from exporting food to having a few million starving kids with flies in their eyes for Sally Struthers to throw into our faces in desperate pleas for us to throw money down a rathole. Sure I'd donate money.. if it was for buying guns to overthow a despotic tyrant AND educating the people how to avoid installing yet another charismatic socialist.

    And at any rate, getting a low level product like sugar is fairly easy, often with marginal crops or tailings from stuff raised for human consumption.
