In your opinion, what would you use as fuel?

Question

I'm currently in school right now. I'm using answers for research.please answer this as soon as possible

Answer 1

Solar! Wind, wave, Geothermal, smal hydro elect, nuks. all are unsafe in some way. I like liquid air but it can be very dangerous.

I attended the Focus the Nation at Sierra College on 1-31-08. The event was the 2% Solution, a 2% reduction over 40 years to solve GW. Oil is a nonrenewable resource and we are running out-but not soon - $30 Gal for gas. The 2% Solution is ok for the USA for a 10 year plan to cut 20%. But over those 10 years, we have to be building renewable energy and about that time, we can cut an additional 20%. This should get us from importing any oil. We must have a pollution surcharge where we pay the real price (health effects, GW and cleanup) for oil, NG, coal, cigarettes, Cooling Towers, Cars, trains and airplanes. Humans have to put some of this nonrenewable into renewable energy like small hydro-electric dams, concentrating solar power plants, wind and wave machines, nuks, and geothermal. With the peak of oil in the 1970’s, peak NG in the 1990’s, having mined cheep coal, the peak of ocean fishing in the 1980’s, and the peak of uranium in the 1990’s, humans must stop procrastinating and make real changes to keep earth sustainable including in the energy debate, finance and regulation.

Many of mankind’s advancements cause earth surface to warm, destroy the ozone layer, kill off endanger species, heat cities, and in some way cause more dramatic destruction.  Blacktop and buildings (roads, roofs and parking lots-heat cities), deforestation (air pollution, soil erosion), duststorms (increase hurricanes and cyclones, cause lung diseases), fires (cause pollution, mud slides, and deforestation), refrigerants (like CFC's) and solvents (including benzene destroy the ozone layer raising skin cancer rates) and plastics; cars, airplanes, ships and most electricity production (causes pollution including raised CO2 levels and increased lung and other diseases); these human problems we must fix to keep life on earth sustainable! Humans have destroyed half of the wetlands, cut down nearly half of the rain forest, and advance on the earths grasslands while advancing desertification which increases duststorms.

The result is:  change is on the way, we just do not know what changes (where and when). Look beyond the hype, beyond the weather, beyond a quarterly report and beyond today. President Bush has made a choice of energy (ethanol) over food and feeding the starving people around the world; this is a choice China has rejected. The fact is Bush wants to buy your food to send to starving people since our is not available.

Over the next 90 years carbon dioxide is projected to skyrocket as human’s burn more fossil fuels. The problem is, the oil will be gone in 30 years at present rates of consumption without projected increases. We have to come up with what will take its place. Again we have to cleanup our mess. One of the big problems we have is at some time Yellowstone will blow its top again, as the magma move closer to the surface, creating a nuk winter. After that we will not have to worry about the destruction of the ozone layer.

But with that we must understand we have never seen what is now happening before. CO2 has never lead to temperature change, but temperature change has led to increases in CO2. The models have to be made as we go along with current evidence! But again adding a small amount of CO2 to the atmosphere enlarges the earths sun collection causing warming; increase water in the atmosphere and it forms clouds cooling earth but sometimes causing flooding. Even natural events are warming earth and causing destruction. The sun has an increased magnetic field causing increases in earthquakes (more destruction), volcanoes (wow, great destruction), and sun spots. Lighting produces ozone near the surface (raising air pollution levels). The USA Mayor's have taken a stand and I believe are on the right track, we can have control and can have economic growth. The sun is available to produce energy, bring light to buildings and makes most of human’s fresh water. Composting is the answer to desertification. New dams are the answer to fresh water storage, energy and cooling earth by evaporation, we need many small ones all over (California needs 100 by 2012 and has not even started).

That is why I founded CoolingEarth.org, a geoengineering web sight where you can learn more about earth, the atmosphere, and how to sustain life on earth’s surface.

Answer 3

Electric:

- can be made from any primary source, including renewables;

- large generators constantly monitored & maintained using unrefined fuel close to source are very efficient & low polluting compared to infernal combustion;

- can be made at home or delivered to home or work by a very efficient existing ditribution system;

-motors provide max torque from 0 rpm from cold so very suited to traction applications; see http://www.killacycle.com

-simple construction & transmission, so cheap to mass produce and maintain;

- quiet, smooth & smell free in operation = enjoyable to drive;

- regenerative brakeing & no energy use when stationary;

- battery technology can already meet our personal transport needs, eg 200mile range; 10 minute recharge; 27 year life expectancy; fully recyclable. see http://www.phoeixmotorcars.com

and can be used to back-up the grid power-supply, esential if we watn more renewables in the system, see http://www.acpropulsion.com/technology/v...

Answer 5

Traditional fuels such as oil.  There are no fuels out there as efficient, abundant, or as cheap as oil.  While there may be alternatives out there, such as ethanol, oil is still vastly superior.  Ethanol is only a viable option right now because it's subsidized by the government so heavily.  And even though it is viable, it's still more expensive.  It's much more difficult to ship, is much less efficient, and drives up the cost of everything else.  It takes more energy to produce than it yields.  By taking our corn we normally would have used for food, or producing food, we're burning up for fuel.  We're the only civilization in the history of the world to burn it's foodstock.  And because our corn is being allocated to fuel, it drives up the cost in other industries.  Just go to the grocery store and look around.  Everything has increased.  Milk is much more expensive, cereal is higher, even soap is way up.  All because they are all dependent on corn in some way.  We have reserves of oil that could last us for possibly hundreds of years longer, and those are only the reserves we know about.  There might even be more.  So, I'll take oil as my first choice.

Answer 6

To power my home I would like to use wind.  I live in TX and it's always windy here.  As for cars I think electric is the way to go especially with gas prices the way they are.  I think the government should start putting money towards developing these technologies

Answer 7

I think it would be cool if we could somehow harvest the gasses from garbage (like back to the future) and use that as fuel for our home, cars, etc.  Wouldn't it be neet if after you finish off that gallon of milk instead of putting it in the recylce bin, you put it in a garbage disposal type machine witch burns it up to nothing but ash but heats or cools your home.

I don't know the safest fuel, because they all somehow hurt our earth, but if I were to guess it would be propane.
