Does anyone see a problem with hydrogen energy?

Question

I know with the crises at hand it seems a valuable option but what happens when we start eradicating the oceans and seas. I mean the ice caps are already melting. Isn't this a defence mechanism of the earth to heal itself? What would happen if we started to depleat our water supply? I think we need to research more on solar power. What are your thoughts?

I realize that the only emition would be water vapor, but it would also be filled with contaminates as well wouldn't it? All I'm saying is that we need to quit trying to use our natural resources and use the most powerful energy source known to man, the sun.

Answer 1

Nothing like driving the family around in a mini version of the Challenger.

Look at all the fuel leaks the shuttle has. Imagine how hard it will be to prevent leaks in H2 cars.

Answer 2

First hydrogen is NOT A FUEL. You can't mine hydrogen, you have to extract it via electrolysis, or the iodine sulfuric acid combo etc... which are both not very efficient.. and both require energy to make the conversion. Think about it for two seconds (I know it's hard).. How much oil do we get from drilling??? The answer is billions of barrels, and the cost is a very small amount of fuel in percentage. It cost around half the efficiency to produce hydrogen fuel. We didn't have to do any work to store the energy provided by oil.. millions of years of decay did it for us. Now that, that is cleared up.. the product of burning hydrogen is water vapor.. so we will not run short on water.

Now as for solar power...The amount of power the sun shines down on the earth is 1 kw/m^2 and is only 10% efficient at best (and this is when the sun is shining). You would need solar panels EVERYWHERE. I'm talking wipe out the forest near your house cause we need more solar panels.

My thoughts... Nuclear. That is the only thing that is anywhere near as efficient. And for those of you about to whine about Chernobyl.. Look up pebble bed reactors mmkay, we have come a long way since 1986.

I think your healing comment is in relation to the Gaia Hypothesis to where the earth has cycles and ways to repair itself. As to your main question I think Hydrogen is an excellent energy source and do not understand why you believe this would depleat our water supply. Hydrogen engines essentially take 2 hydrogen atoms and a oxygen atom and the emmissions is water. You dont fill your car up with water. As to solor power there are several companies out there doing great work with thin solar cells electronics companies such as Kyocera are comming up with great solutions. As for the melting of the ice caps it is proven that the Earth goes through heating and cooling stages and that we have had several ice ages over many stages in the Earth history. I would not be overally worried as the place where technology has taken us in 100 years is amazing and I know the next 100 will be that much more impressive.

Good luck.

The oil companies do no longer sell hydrogen. additionally, it incredibly is particularly elementary for all people to produce hydrogen, while in comparison with drilling for oil, as a consequence destroying the oil companies monopoly. Hydrogen is risky, yet so is LP gasoline and gas. there are the right thank you to make is as secure as gas. EAST POLE: good factors. Your power, performance vs pollutants math makes proper experience. I do agree that finally, electrical energy is ultimate for transportation. in spite of the undeniable fact that it may be extra fee-valuable to bypass hydrogen first as you're able to swap contemporary automobiles. that could be the unmarried best fee going all electric. i became at Cal State interior the '70s and a few adult adult males took a Mercury Bobcat (think of Ford Pinto) and made an electric motor vehicle. i could help them on occasion. It became run by using 40 8 volt bus batteries. We used a backyard mower engine to fee them. while the volt meter have been given to 40 six volts or so, we had reachable start up the backyard mower engine. no longer precisely hi tech yet incredibly the significant at the back of the hybrid. the main appropriate concern became coupling the output of the electrical powered motor to the wheels. That became a project. while they have been on condition that found out, they have been getting over 70 miles in step with gallon. there became nevertheless plenty room for progression. you're superb touching directly to the interior combustion engine and 20% performance. it incredibly is surely late 1800's technologies. the great element approximately electric vehicles is once you're coming to a give up and the motor vehicle's inertia is turning the wheel, the motor turns right into a generator and dumps potential returned into the batteries. additionally, once you're stopped at a easy, you're using no power. electric is a thank you to bypass and photograph voltaic is so below utilized. by using this time i could have concept we would a minimum of be supplementing popular potential with photograph voltaic. stupid me.

Answer 5

Hydrogen is highly volital & burns clear which is a draw back but the only wast is water. The military has ben using hydrogen fule cells for years & GM has devoluped a fule cell car, The hangup is producing & distrubiting hydrogen gas. The reason for the slow change to alteranet energy sorces is greed.. Fossel fules are cheep & companys wood rather have a fast buck thain a healthy enviorment.

Answer 6

Currently the only problem with hydrogen as a fuel source is that it takes as much conventional energy to split the h2o bond as it would produce in energy.

We definitely need to make solar power more affordable so that we can make cooperative grids in residential neighborhoods or the roof tops (especially in the southwest).

Answer 7

If you are thinking of making electrical energy from hydrogen, that could be a problem as you could wind of with a thermo nuclear hydrogen bomb if something went wrong. That would certainly give you a lot of energy but you might not want it.

Answer 8

jhillftp where did you get 1kw/m2? In southern Canada there is an anual average of 3.34kwh/m2 (that's counting dark winters). And as for solar panel efficiencies, they are getting up to the 30-40% efficiency range with experimental models.

Answer 9

First it takes energy to make it, diluting any benefit. Second, that an entirely new infrastructure will need to be built, costing a heck of a lot of money that we could be using for other things. Third is they want us to use some sort of resource to get around because they want something they can tax us for.

Answer 10

No, one only needs to put solar electric current to water and capture the gas.
Where did you ever get the idea of eradication of the oceans? What we are doing is overfishing them where they are on the edge of total collapse.
