what is the cost of biomass?

I'm not sure exactly what you're getting at with this question. Biomass just refers to any organic substance on the planet: plants, animals, bacteria...  See first link below.\n\nWhen people talk about the relative "cost" of biomass, they are often comparing the amount of water and energy it takes to create a certain amount of plant biomass (e.g., 1 kg of wheat) vs the same amount of animal biomass (e.g., 1 kg of steak). Because of the way the food chain works, it takes a lot more resources to create meat for consumption than it does to produce a plant-based (vegetarian) diet. A lot of people therefore eat vegetarian because it's better for the environment (and the earth can sustain a LOT more people on a vegetarian diet.) See second link below for details.\n\nBiomass can also be burned for energy  - e.g. chaff, manure, or peat. This is usually called biofuel. The efficiency depends on the material, but like all methods of producing energy, there is some pollution generated by burning.\n\nI hope this is helpful.

As I recall, the price went to about .75 to .85 per gallon.  This was about the time I went off to college and I remember thinking how hard it was going to be to make my $ stretch.

According to the USDA ethanol is a viable fuel. On average 67% more Btus of ethanol are produced than various fuels are consumed in the farming and manufacturing process. The oil companies disagree with this siting data from 1970s showing the farming of corn to use to much energy for ethanol to be viable. \n\nCellulose ethanol will be even better as you can harvest 10 tons of cellulose using less fuel than the fuel required to harvest 2.5 tons of corn. As technology gets better, these types of fuels will get even better. \n\nButanol would be an even better fuel than ethanol. A recent development research found a way to produce as much butanol per bushel of corn as you can produce ethanol. What is great about butanol is that it has 42% more BTUs per gallon than ethanol(just a little less than btus in gasoline). Butanol also isn't corrosive so it can be used in any current gas engine at 100% butanol. It is underdeveloperd however. Last year the creators were searching for funds to develope a pilot plant. It can currently be made with corn at 1.86 per gallon or from lactose (waste from cheese factories) at 85 cents a gallon. \n\nSolar power is a good power source, but small. A heat collecting panel 4 foot wide and long as a house can provide enough heat to replace the heater in winter almost all of the time. Solar panels for electricity are to weak to replace much. It takes better than a decade to pay for itself. Not good enough for most people.\n\nNuclear power is a over dramatized technology. It is safe. The last set of nuclear power plants won't explode by accident. Some of the new designs of nuclear plants might not explode if someone does try to destroy. The ironic thing here is if the public wouldn't have forced most research to go away, most of the problems associated with nuclear power probably would have been solved by now. \n\nWind, is the best developed electricity generator today. The technology is getting cheaper, but unfortunately is still more expensive than coal. In the future we may be seeing massive helium balloons that spin in the wind for the purpose of generating electricity. According to the company working on the design this will be far less expensive than current wind mills due to no costs associated with erecting towers. Rather the balloons only link to the ground is one long chain. \n\nthere are a lot of other stuff out there.

Rs. 36.50 per kg if you produce 100 kgs\n\nRs. 28.00 per kg if you produce more than 200 kgs\nand upto 350 kgs.\n\nIf 1000 kgs+ are produced the cost comes \ndown to Rs.18.00 only.

The Air Force recently estimated fuel costs for Air Force One have risen to $6,029 per hour, up from $3,974 an hour in the last budget year.

Research the cost of the following things:\n1. Facility (including insurance, hydro etc)\n2. Equipment\n3. Personnel\n4. Advertising (very expensive at the beginning)\n\nI can't think of any others right now.

Hey, it's what it is and nothing you can do about it. Many countries have higher oil prices. In United States, the national average is more than US $2.50 per gallon, which is around RM 2.51 per litter. So suck it up and live with it.

Not sure I understand your question....\nThe total mass of the earth is 6x10^24 kg.\nThe total human world population is about 6.6 x 10^9. Assuming an average weight of 50 kg, this give a total human mass of 3.3 x 10^11 kg, far smaller than the earth.  \nThe total biomass (all plants and animals together) is estimated here\nhttp://en.wikipedia.org/wiki/Biomass\nat about 2x10^15 kg, still 9 orders of magnitude smaller than the mass of the earth.

That depends on whom you believe. If you believe the oil industry it takes 1.5 btus of oil to produce 1 btu of ethanol. If you believe the US Department of Agriculture it takes 1 btu of oil to produce 1.67 btus of ethanol on adverage. \n\nPersonally I believe the USDA. I have read both views, and both take into account fertilizer, fuel, etc. The problem with the one that originally said 1.5:1 was that it hasn't reflected changes in efficiency in farming in the last 30 years. That view keeps changing under the force of criticism, and it really looks like they are trying to prove a perconcieved notion rather than come to a conclusion.\n\nSo I believe that ethanol production is efficient.

The best thing to do is not meddle. If price gets high enough, people will be forced to conserve. Prices are usually over $4 per gallon in Europe and over $3 per gallon for most of Latin America. Perhaps prices would be more stable if North America were to stop wasting the world's fuel supply.

I pressume you are asking about biomass.\n\nConverting energy from one form to another is never 100% efficient.\nNot all the energy illuminating a plant will be fixed into manufactured organic chemicals (BIOMASS)\nOnly some of the energy available in organic chemicals (food) will be available for animals to build BIOMASS.\n\nAssume 100 units of light energy available, and a 10% energy transfer efficiency, then;\nSun to plant - 10 energy units fixed, and\nPlant to animal - 1 energy unit fixed.\nSo the amount of BIOMASS that could be made decreases dramatically at each trophic level.\n\nALSO - don't forget that some BIOMASS is RESPIRED by the organisms  at each trophic level and is therefore not available to the next level.\n\nNo surprise then that diagrams of biomass for the organisms in an ecosystem look like a pyramid, and that any ecosystem can only support very few top carnivores.

A bushel of corn yields ethanol that can be burned for about 200,000 BTU.  Food grade corn oil is not typically burned as fuel, so there isn't any readily available information about it in that respect.

it is the opinion of most biologists that the sea contains much more biomass

yes it is very costly
