In response to the hydrogen volume issue, see this about storing it in carbon nanotubes. Though it's still very crude - my daydream from ten years back was a finely tunable system that could be controlled with a simple voltage, so that you could use it inflate and deflate your solar cell covered zeppelin. But I want a truly quiet zeppelin that uses a siphon along the middle to glide through the air, and has good terahertz senses of all the surrounding windflow patterns for safety and efficiency.

I wonder where

The blue is all the current computer models for ice melting. The red shows actual observed melting. It's melting faster than all the models.

But that's just another excuse for all the naysayers to say computer models don't work

well they do, but you have to model all the variables, and in a system as complex as climate, they seem to be quite a long way off.

I was suprised to read that positive feedbacks caused by tundra melting weren't in the models. Of course the fact that methane didn't really increase lately makes that all seem odd anyways...

I wonder if reflection of light, (albedo effect) is in the models? Like when the ice goes, the sun is shining on blue rather than white.

Seems like it would reflect quite a bit less, so the ocean would warm up faster.

Un solution andalou.

One thing they never model - they can't, really, because there's no data - is that the past two million years is a short period evolutionarily speaking, but has featured a wide range of climate conditions. My guess is that we can expect many living things to be genetically equipped to recognize a distinction between an ice age and an interglacial period, and react differently - which will itself to some extent affect the climate, particularly in some localities like the arctic where a few hundred miles' shift in range isn't a ready solution to climate change.

I think solar towers are way cool. I think there's a big one under construction in Australia.

In solar, the big lesson of the last 20 years has been: concentrating is cheap, generating is expensive.

I think I'll build a big magnifying glass to shine towards my cheapo canadian tire solar array.

lots of weird science movies on youtube these days. permanent magnet motors

Here's an interesting one: high-altitude kites that harness the jest stream.

I know, the cable, the cable, the cable will be a problem. But with all the talk of space elevators, it seems this would be relatively simple by comparison.

China and the U.S.A don't care if you little countries get too hot. We pwn j00! Be quiet worms, or we'll eat your kids!!!

ipcc says the world has 8 years to change

for some reason I'm polluting a bit more this year. I think I believe that if people know this problem change will happen... ok maybe I'm just getting lazy.

UN warns on bio-fuels.

a link on three flying windmill schemes


I've been thinking about this one a lot. I mean if a few baloons on strings could solve all the problems, lets send em up. 5,6k of electrical transmission is nothing...we send electricity 100's of k down the wires each day...

I guess the nature of a rapid current in a river is that it pushes spinning objects out of its stream...

Those various wind powered devices look interesting. I'm fairly sure one could make a kite version of the blimp one, just for fun. There are rotor kites available of various sizes and cheap and light neomodium magnets are easy to come by.

I don't think it would be too difficult put a magnet (or even a few magnets) into a coil which is rotated by the spinning kite. The kite string can be replaced by light weight electrical cable, or possibly keep the kite string and have a loose cable hanging from the bottom (depending on the weight requirements).

I'm trying to find a link to an item reported on the radio this morning.

Supposedly the ongoing deforestation in tropical rainforests is contributing more to the buildup of CO2 globally than the burning of fossil fuels - by several orders of magnitude.

I've no idea if that's the case, but it suggests we should be doing a great deal more to save the planet's remaining rainforests and compensating the countries whose economies would be affected.

There was a report a few weeks ago that burning rainforest in Malyasia/Indonesia, and particularly the subsurface fires that burn for ages, are creating about 20% of manmade greenhouse gases.

These guys seem to have algae working.

50 times more ethanol than soybeans, and soybeans give more than corn.




looks expensive to build though... They actually have to keep the algae out of the sun. They should grow it in canada where we're out of the sun most of the time...
