Hydrogen powered GA aircraft
Hi, i was wondering what is the possiblity of having hydrogen powered GA aircraft in the future. Is it going to be a good idea or some nonsense like solar powered planes.

When gasoline finally runs out in about 250 years time I expect someone will have found a solution. When commonsense finally has its say and CO2 is found to not be the poison that politicians lie about to raise taxes without a cold war excuse it should be possible to fly without the myth of a carbon footprint shadowing every means of transport yet devised. Amazing isn't it that carbon, the 4th most plentiful element and the reason that we and plants exist [carbon life forms] has been made a 'poison' by the US EPA and AL Gore is shafting everyone with his carbon offset trading [shades of the South Sea Bubble].
Carbon Dioxide is neither a poison or polluter. Without it we die, plants love it, the more they get, the bigger they grow.

Are you joking or you belive in what you just wrote?
The only thing i could see was correct is ""Without it we die, plants love it""
We die without water also but still it can kill us
exessed CO2 are created by human and can not be used by nature , it is just TO MUCH

We are a carbon based life form. There is 90 times the CO2 in the oceans than in the atmosphere.
I am a realist [Not that old Flat Earth Greenie garbage propaganda] You must be a
carbophobe?
What do you think CO2 does other than allow us and all the vegetation in the world survive. More CO2 means better plant growth. More Co2 does not mean catastrophic temperature increases, melting ice caps or city swamping sea level rises.
When we exceed the temperature levels of the Medieval Warm Period - about 5ºC warmer than now - let me know. Until then I am not paying any trumped up Carbon Tax or Carbon Offset scam.

the possiblity of having hydrogen powered GA aircraft in the future
I have an old book from the 1920s that assured readers that by 1950 everyone would have a personal aircraft in their garage and it would be powered by electricity sent by radio from the ground. We're still waiting. On the other hand when the C152 first came out could anyone have forecast that in 2009 we'd still be flying them?
The same technology developed for hydrogen powered cars could conceivably be adapted for GA aircraft, but this would mean also a new infrastructure for fuelling, new regulations and so on. Maybe before this happens electric propulsion really will develop in unexpected ways.

It wasn't so long ago you could fly London - NYC in less than 3 hours (with the money).........The good old days! 
aviate1138 I tend to subscribe to your believes. And if everyone is so concerned, stop eating Beef and drinking cows milk! Dairy farming and the resultant flatulance accounts for 18% of so called green house gases.

The big issue with H2 is storage. If you store it as compressed gas, your max range will be about the length of a long runway. Liquify it, and for a practical range you'll fill the whole fuselage with a tank and insulation. Metal hydride storage is denser, but you need to heat it to release the gas. Someone may overcome these issues someday, but it doesn't look promising right now.
Yes, the C152 has been around, but it's descended from the 1946 C140 which was a better, more efficient airplane. There was even a flapless C120 which was useful for building proficiency in slips!

Report: Climate change crisis 'catastrophic'
The first comprehensive report into the human cost of climate change warns the world is in the throes of a "silent crisis" that is killing 300,000 people each year.
He told CNN: "The U.S. administration has joined the mainstream about fighting climate change and that is a big step, and I hope that will also put a new momentum into the negotiations."
The report's startling numbers are based on calculations by the Intergovernmental Panel on Climate Change that the Earth's atmosphere warmed by 0.74 degrees Celsius (1.33 degrees Fahrenheit) from 1906 to 2005, with much of that increase coming in recent decades. The panel predicts that by 2100 temperatures will have increased a minimum of two degrees Celsius (3.6 degrees Fahrenheit) over pre-industrial levels regardless of what's agreed in Copenhagen.
"No matter what," the report concludes, "the suffering documented in this report is only the beginning." A rise of two degrees, it says, "would be catastrophic."
Of the 300,000 lives being lost each year due to climate change, the report finds nine out of 10 are related to "gradual environmental degradation," and that deaths caused by climate-related malnutrition, diarrhea and malaria outnumber direct fatalities from weather-related disasters.
