Two Google Engineers Say Renewables Can't Cure Climate Change

able1234au Re:Maybe, maybe not. (623 comments)

If the cost of the CO2 (the carbon price) is added then Coal and Oil are not as cheap as they are. It is only that the users of coal don't have to pay for the cleanup of the environment. Nuclear is all well and good but there are some scary cleanup/storage costs that are not at all clear.

How the World's Agricultural Boom Has Changed CO2 Cycles

able1234au Re:Awesome! (183 comments)

Growing corn for ethanol always seemed to me a poor choice. Better to generate biofuel from the inedible waste plant material.

How the World's Agricultural Boom Has Changed CO2 Cycles

able1234au Re:Problem? (183 comments)

There is no Northern Hemisphere "bias". It is just that there is more land in the northern hemisphere and more cropland. So it influences the seasonal cycle more. There would be no CO2 advantage to moving the crops from the Northern Hemisphere to the Southern Hemisphere. It would be nett neutral.

How the World's Agricultural Boom Has Changed CO2 Cycles

able1234au Re:Riiiight. (183 comments)

Best to read the source article http://www.nature.com/nature/j...

They are looking at the seasonal swing of CO2, it goes down in Summer and up in Winter. They are not saying it causes a net CO2 gain. It agrees with the book chapter you linked.

Cutting down trees which grow slowly and only few die each year, does increase the seasonal swing as you replace them by fast growing plants that die off every year.

True but slower growing and slower dying. Less in, less out.

After Four Days, Philae Team Gets to Rest

able1234au Re:RTG (88 comments)

Two problems. ESA does not have access to the plutonium as i understand it. The second issue is that it would have made the unit much heavier and so needed a bigger rocket to be able to meet the timelines.

The Strangeness of the Mars One Project

able1234au Re:M.O.O.N. that spells Mars (246 comments)

That should be the first step. Learn how to mine the moon, export water to space, split the water to make fuel, oxygen etc. Mine moon materials and be self sufficient within easy communications range of earth. The skills learned there will be useful in eventually going to Mars. The distance for resupply is more realistic. The fuel created can be used for other missions. It is the next logical step from the ISS.

Will the Google Car Turn Out To Be the Apple Newton of Automobiles?

able1234au The best idea (287 comments)

Is it start with a limited environment. Have these operate in large resorts, amusement parks, wildlife reserves etc. Build a big base of realworld usage before venturing further afield.

White House Wants Ideas For "Bootstrapping a Solar System Civilization"

Those wimpy environ-liberals are so weak they fear being irradiated by exploding rockets. Where is the fun in that. I look forward to having three eyes and a tail.

Battery Breakthrough: Researchers Claim 70% Charge In 2 Minutes, 20-Year Life

able1234au Re:Charging amperage (395 comments)

Battery swaps eliminates the cost from replacing your batteries every 10 (?) years. But then again, i guess the cost would be amortized into every swap you do.

Battery Breakthrough: Researchers Claim 70% Charge In 2 Minutes, 20-Year Life

able1234au Re:No mention on capacity though (395 comments)

'gas stations' will still have a role for rapid charging but yes, most charging would be trickle charging. If you are travelling long distance, have a problem with your charging at home, are staying at a house without trickle charging etc etc, then there will always be exceptions. And gas stations will still sell petrol, diesel, natural gas etc. But i would expect there will be a lot less of them and they will need to change their business model.

NASA Study: Ocean Abyss Has Not Warmed

able1234au Re:Null hypothesis (295 comments)

Except global temperatures have not plateaued and continue to rise. The rate of the rise changes but it is continuing to rise. The "plateau" is only spin using a very crude line from a peak in 1998. http://www.skepticalscience.co...

The warming cannot be explained by an inter-glacial. Dumping millions of years of stored carbon into the upper atmosphere is not surprisingly having an effect on the climate. Land use changes, clear felling, road and city concreting do not help either.

This study is going to help refine the calculations of where heat is stored and how it changes over time but don't delude yourself that this is not related to human activity. Even most deniers have stopped denying that.

Water Discovered In Exoplanet Atmosphere

able1234au Re:We care why? (50 comments)

And it is thought that the water on earth did not all come from comets, as there is too much for that to happen. They now think that it came from processes within the earth itself. So the basic ideas are still changing.

Quickflix Wants Netflix To Drop Australian VPN Users

able1234au Re:International Copyright (172 comments)

I think it is distribution rights, copyright rights. Netflix would have to pay the right entities so you could watch that movie

such as by effectively killing the NBN which would provide a high speed network allowing people to stream TV, movies etc in 4K, thereby rendering Foxtel unneeded.
