Physics Meets Biology

[UpNfamish2]

Grow Solar Trees?A Solar Tree is a genetic modified tree that is capable to deliver electricity that can be grid-tie !!! I will say this is the final Union of Physics and Biology.

But during those big cycles of Ice Ages, there were no humans!! We might all vanish or reduced to a so small number inside the last big cycle.Our civilization(that is the most important to us, not just bare existence as humanoids) is most important.Our multi-billions civilization might not survive inside the last cycle.

he knows the situation, he knows it can be done but as energy secretary he sits back and hopes retards like GM with people like Bob Lutz who says global warming is a crock, will solve it.

Chu, you can't rely on idiots in power to do it. you have to set up companies that do exactly the right thing, not tiny gradual changes but exactly the right thing without compromise. for cars that's ultra light ultra aerodynamics battery electric drive with perhaps tiny range extenders. power is wind and PV

[Maskmanx]

I love Steven Chu's silly analogies

i hate lissening to some one trying to explain why global warning because it's never scientific, heat goes up and down, but they only talk about it going up, and they leave out the down part. plus, lol , the estiments they are using don't work, if you use there program, put in old data,, you don't get current data, if it doesn't work, than it doesn't work, stop using it. and stop petending you can use it to tell any one any thing

You can't be serious!

@MEASEMAN11 if u think u understand science, you dont understand science. so please just shut up. get a phd or a nobel prize like this guy first, before you come out and spitxx xxx around

[LDNLeon]

@MEASEMAN11 Are you a cretin?

He explained in very simple terms why we should be wary of greenhouse gases. Science agrees: climate change is happening - read the published papers, do some real research, don't just get spoon-fed by science illiterates like Limbaugh. Listen to the scientists in the climate field.

[DanFrederiksen]

@MEASEMAN11 I think you learn spelling, then hard sciences a while later.

Green plants in the light sink CO2 down to 0.00037% today. More CO2, more life! CO2 thus goes up in an ice age!

[mikomagic1984]

the thought is realy nice, though sad as it is the truth is in the speech, or any speech of its kind. we are human we progress. we are pepole

[Sonyoooo3]

The north and south pole are melting?

So the effect will be new Ice age?

[MEASEMAN11]

the south pole is not melting,,, for every unit of ice melting in the north,, 2 unit are added in the south

A transcript would be awesome. I'd be able to glean the main ideas in a shorter amount of time.

[xinssun]

awesome video good presentation!

[yoolen]

Anyone know where I could get transcripts of these presentations?

[soulestazn]
