Ed Cesnalis Posted February 12, 2016 Author Report Share Posted February 12, 2016 Sea levels rising = climate change Sea level not rising = even bigger climate change! No matter what happens or doesn’t happen regarding the Earth’s climate, it is evidence of climate change. http://news.yahoo.com/parched-earth-soaks-water-slowing-sea-level-rise-231245199.html Link to comment Share on other sites More sharing options...

Roger Lee Posted February 12, 2016 Report Share Posted February 12, 2016 When it's cold in Tucson, Az at 80F the CT group goes camping in Tombstone, AZ where it is 75F. Then we head up to the old silver mines in the foothills to explore in the UTV's. Burrrrr, snow. Climate change. Can't wait until it gets warm again.

Ed Cesnalis Posted February 14, 2016 Author Report Share Posted February 14, 2016 Andy, I'm shocked, shocked I tell you, where is your head? This is not beating a dead cow it is brand new info from NASA. Global warming is now preventing sea-level rise, shocking as well. NASA is also in the news this week because it is being sued for censoring its employees. Their long standing Christian organization, open to all has been told by NASA that it is unconstitutional for them to use the name 'Jesus' in their Emails. Not only has this been a problem for Jesus Ortega and others with similar names it does make you question how NASA's mandate can be about Muslim outreach but its unconstitutional to say 'Jesus' When I ask has NASA lost its way I do mean it has become political. Can't we get back to the earlier mandate and drop the politics? Can't we at least ask the question without fighting left vs right? Link to comment Share on other sites More sharing options...

And at this time only experimental. Charge downtime and weight being severe limiting factors. Cheers Link to comment Share on other sites More sharing options...
gbigs Posted June 20, 2016 Report Share Posted June 20, 2016 The press is making a big deal out of both the NASA prototype and the solar plane that is flying around the world. They are curiosities, but not practical for mainline GA or commercial service. A Chinese drone/helo is large enough to carry people on short hops across a city - electric (hands free). http://time.com/4171329/drone-helicopter-ehang-184-ces/ Pipistrel is making an all electric and a hybrid part gas/electric plane. So there is some effort to get lower emissions aircraft in the air....but until battery tech takes a quantum leap (so far only micro electronics in motors has leaped) then like electric cars, both range and cold weather will limit both devices. Side note, I always thought there was hypocrisy in aviation when it comes to 100LL and emissions. It's why I didn't burn 100LL in my CT. But I am forced to burn it in my Cirrus so I am a hypocrite now too. Link to comment Share on other sites More sharing options...
Anticept Posted June 20, 2016 Report Share Posted June 20, 2016 I believe we're more likely to see hydrogen cells replacing petrol before solar/battery in large aviation. Even the best batteries are 20x less energy dense than petrol, and we can't unload the weight by putting less charge in! Or we'll figure out a better way to make biodiesel.

Doug G. Posted June 20, 2016 Report Share Posted June 20, 2016 There is also some promising work with capacitors. They would be light and charge much faster than batteries. Link to comment Share on other sites More sharing options...
Anticept Posted June 20, 2016 Report Share Posted June 20, 2016 Ultracapacitors still don't have the energy density (storage capacity) of batteries... Actually still quite a ways off. They have a great power density though, which affects how quickly they can store and release the charge. The COST, however, is no contest. Gas is far,far, far cheaper.

There was supposed to be a breakthrough using carbon nanotubes a while back, but I have not heard anything for a number of months, other than a chat I had with a couple of guys at an AOPA fly-in who claimed to be working on it for aviation use.

Now we reach a full level of absurdity. They KNOW they don't have the data but rather than admit defeat they insist on making bigger horses-asses of themselves by asserting they can now 'feel' the problem.

Cluemeister Posted July 1, 2016 Report Share Posted July 1, 2016 When I was a kid "acid rain" was going to kill us. Then it was the "ozone hole". Somehow that hole just went away one day. Now "global warming", umm "climate change" is going to finish us off. The solution is always the same to every crisis: Give the government more money and control. Why isn't the solution ever less government? Link to comment Share on other sites More sharing options...
Doug G. Posted July 2, 2016 Report Share Posted July 2, 2016 You actually don't know why acid rain and the ozone layer improved (the hole has improved but is still there)? Have you heard of any warnings for serious air pollution in LA lately? How about the pollution in Lake Erie? Or, Love Canal type situations? To make broad statements there is a need to not only be aware of the changes, but the factors that have brought about those changes. Link to comment Share on other sites More sharing options...
Ed Cesnalis Posted July 2, 2016 Author Report Share Posted July 2, 2016 First our 'chicken little' government identifies a fictitious problem and it becomes more powerful in order to solve it. Last the govt takes credit for solving the problem when it is not longer a threat in their opinion. In realiity nothing has changed in regards to the fictitious threat.

To make broad statements there is a need to not only be aware of the changes, but the factors that have brought about those changes. The ozone hole is smaller and no one knows why, remember, the green alarmists daily claim the CO2 levels are higher than ever. LA's pollution is still there, it comes from pollution from China and natural phenom from the desert and the valley inversions...same with other California cities. Can you stop China from polluting? No. Superfund cleanup money comes from corp America....this is not the same as demanding taxpayers pay through govt force the billions lost to goofs doing fake global warming studies. It's a false reach to assert the extreme green movement today demanding outrageous changes in the overall economy due to no data is justified because some cleanup was once necessary after the industrial revolution.

Doug G. Posted July 2, 2016 Report Share Posted July 2, 2016 So, why is LA no longer issuing air quality warnings on a regular basis. Which was common in the '60s - '70s? People died. Link to comment Share on other sites More sharing options...
