And if it's a medical device, by the time the doctors get hold of it and charge their "special" markup (because we can), it will be no cheaper (and probably more expensive) than existing ultrasound.

Unfortunately, natural gas is not environmentally friendly. We've been lied to by the fracking industry (surprise!). Natural gas does have less CO2 than coal but it still emits CO2. The worse part is that natural gas itself is 34 times as potent as CO2 in the global warming department and fracking is particularly "leaky" leading to lots of this greenhouse gas in the atmosphere.
So... we need to get off of all fossil fuels, including natural gas.

It's hard to know what to do when you have more money than you can possibly spend. What a dilemma!
Let's see... 10 minutes of fear, joy, excitement?
Or... give some money to "poor people"? ... not much excitement in that.
I just don't have a frame of reference for the dilemma these people face.

2007? What happened in 2007? Run up to the financial crash when Wall Street screwed everyone?
I think we should go back to 1776 to get the real story.

... or he could be worse...

... and to a "well regulated militia"...

I worked in Reno where all it takes is "some dude". I think the EtOH and late night gambling makes for easy targets.
You must have stronger men in your area.

Irony is not realizing that we all live on the same planet and exporting pollution to another country solves nothing.

Greenpeace isn't the problem. They have no money and no political power. Corporations are the problem. They have a large vested interest $ in the current carbon economy so don't want renewables... they're probably fine with nuclear power (except the oil and natural gas companies).

I know it's not fashionable to RTFA but the IPCC report does propose actual solutions and costs those solutions (which will have negligible net cost)... they are the well-know solutions of more renewables, nuclear power and carbon sequestration along with a carbon tax.
The problem is that the corporations which have become rich on the current high CO2 emission path control the world's economies and governments so I can safely predict that nothing meaningful will be done and that we are all literally toast.

Back when I worked in the ER, a common complaint was that "some dude" just attacked me.
I always thought that if we could just find "some dude", we could solve a lot of problems.

So you think that the US should be forced back to a pre-industrial society?

About 50% of China's pollution is caused by exports.... so all that cheap crap you buy that's made in China counts towards China's pollution. The corporations have not only outsourced all the jobs to China, but the pollution too.
The pollution from shipping the junk from China (boats and planes) isn't tallied in any accounts so total pollution is more.
So, the pollution drifting over San Francisco is just the pollution catching up with the stuff shipped over and sitting on WalMart shelves.
