Finally! The future is coming. About damn time.



Regarding the post "Sex Sells, But Is It Right for the Green Message?"

Sterling D. Allan said:

It's not innocent. Sex sells for a reason. It lures men to lust after females who are not their significant other, creating problems for those relationship, fueling addictions. This is not good for society.

Do you want to propagate that?



Regarding the post "Estuary Power? Mixing Salt and Fresh Water = Clean Electricity (1 kW per Liter/Second)"

Anonymous said:

"I have an environmental concern too, but it's a bit different than the ones already expressed. What happens to the energy produced now by the natural mixing of salt and fresh water? Does it convert to heat? Would building power plants to extract the energy produced by this mixing result in lower water (and perhaps air) temperatures in the local ecosystem? If so, this could damage the ecosystem. On the other hand, it could counteract the impact of global warming locally. Can anybody answer this question?"

That is a valid concern, but we must keep scale in mind.

The same could be said of wind farms: "But if you capture the wind, aren't you slowing it down and changing the environment?"

Well, trees, mountains and buildings also slow wind down, but even with all of those plus wind turbines, you only capture a very small % of the total energy.

The energy that you capture at the estuary would be similarly small compared to the total, and would likely have a much smaller impact than burning coal or whatever.



Regarding the post "Yikes! Electric YikeBike Like a Barstool on Wheels"

Anonymous said:

I like these things but 4,800? that is madness! even for "its new and with interest the price can come down" for that kind of money you can get a good vespa or a really nice road bike hell you could get two road bikes for when the first one is stolen.

"I wonder how this electrode concept developed by the Italians compare to the membrane technique used by the Norwegians."

The original source mentions it, and says that this is a superior technology (potentially) to the membrane technology because the membranes wears out and get blocked.

There is nothing new in this concept. Statkraft, the norwegian utility, has been researching osmotic power for the last decade and has built such a plant in the Oslo Fjord.

I wonder how this electrode concept developed by the Italians compare to the membrane technique used by the Norwegians.



Regarding the post "Grist has Van Jones' Back As Beck Continues His Smear Campaign"

Anonymous said:

"In the time of chimpanzees I was a monkey,
butane in my veins so I'm out to get the junkie
with the plastic eyeballs, spraypaint the vegetables,
dog food stalls with the beefcake pantyhose,"

As crazy as that is, Beck's lyrics are easier to understand than Glenn Becks paranoid ramblings. I find his definition of providing "proof" laughable at best.

Let me be clear: I am not an "Obama Supporter". I disagree with plenty of the administration's decisions. But Glenn seems to think that if you disagree with someone then you must find find an evil interpretation to EVERYTHING that comes out of their mouth.



Regarding the post "Weird Solar Device of the Day: Hanging Basket Rotator"

Wil S said:

Well, It would be great for my grandmother and great grandmother. They both have trouble lifting there arms over there head to lift heavy things (irony: they can still be out side in the heat all day to work in the garden). This would be a nice present for someone with arthritis.
