By definition, it cedes power and authority to the government.

IMV, not if participation in the health plan is voluntary, which Obama said it would be.

Voluntary? First I've heard of a voluntary universal government program.

Maybe it will be like the presidential election check-off?

I do think it tends to cause more harm than good, yes. When they show a break in the trend, I will change my mind.

I'd have to agree that it works for the oil or any industry that can afford the special interests groups to lobby them. Unfortunately, small industries and we the people don't seem to be able to compete. As such, it works for them and not us Mr Nobodies. That is why I'd rather they stay away and we fly under the radar until this cause or any other is strong enough to stand on it's own.

The operative word there is IF. IF it is voluntary and IF our good friend Mr Obama can actually pull it off by getting congress to sign on. It MIGHT be a good idea if it doesn't get managed to death and we have another thing to bail out.

Or more responsibilities. Why don't we let a kid in 3rd grade who is failing math do calculus III?

You cannot make a whole lot of money by selling mini power plants
to individuals.

Big oil/energy depends on the centralized model to make all the money
that they do.

And that is how they keep us dependent.
The individual person is not able to drill for oil and refine it in his back yard.

But we can put up a windmill in the back yard.
Or a small algae farm.
Or a solar panel.

...

In many ways it is a modern day David verses Goliath story.

Some truth to that. Could be a new day a'comin.'

There's already something called Medicare Plan B which is voluntary as well.

And the rest of Medicare? Is that voluntary too?

I think you know the answer to that.

I see. So we are talking about a voluntary part of a mandatory system.

How did a thread about algae bioreactors turn into a discussion about healthcare? We're slipping, it seems to me. If a thread is going to degenerate into something, let's try to make sure it's something sexual, shall we?

Heat a turn-on for algae

"Heat turns on sex genes in algae, Canadian and American researchers have found.
The multicellular algae Volvox carteri normally spend their lives in ponds reproducing asexually as either male or female colonies.

When summer heats up and their ponds dry out, though, the tiny balls start producing eggs and sperm that merge their DNA in sexual reproduction.

Aurora Nedelcu, a biology professor at the University of New Brunswick, and her colleagues thought the algae may become sexual in response to heat stress.
To simulate the conditions of late summer, Nedelcu put culture plates of the algae in water baths for two hours.

After 10 minutes at 42.5 C, the colonies had twice as many "reactive oxygen species," or free radicals, as the unheated colonies.

When the amount of reactive oxygen doubled, six genes were turned on to change the algal lifestyle from asexual to sexual, the team reported in the June 9 issue of the Proceedings of the Royal Society of London, B.

"This is the first demonstration that stress turns on sex-inducer genes," said Richard Michod, a professor of ecology and evolutionary biology at the University of Arizona, and a co-author of the study.

Why sex evolved is a source of heated debate among biologists, with genetic variation being one common explanation. About 15 years ago, Michod and his colleagues proposed an alternative DNA-repair hypothesis.

According to the DNA-repair hypothesis, the process of dividing up parental genes during sexual reproduction also repairs any DNA damage in the sperm and eggs. That way, any damage to the parents' DNA isn't passed on.

Proponents were looking for evidence from multicellular organisms like the algae.

"For algae, sex is a way to get a double set of chromosomes," Nedelcu told CBC News Online.

With two copies of chromosomes, the algae produce spores with much stronger cell walls that can survive being eaten by birds, she said. An orange, carrot-like pigment also protects the spores from UV radiation."

Stress makes me horney, too. Also, relaxation, heat, cold, . . . . .
