Future energy source is made with... piss

From a group led by chemist Gerardine Botte of Ohio University comes a report that hydrogen has been produced from urine.

"Urine's major constituent is urea, which incorporates four hydrogen atoms per molecule � importantly, less tightly bonded than the hydrogen atoms in water molecules."

"Botte uses electrolysis to break the molecule apart, developing an inexpensive new nickel-based electrode to selectively and efficiently oxidise the urea. To break the molecule down, a voltage of 0.37V needs to be applied across the cell � much less than the 1.23V needed to split water."

"'During the electrochemical process the urea gets adsorbed on to the nickel electrode surface, which passes the electrons needed to break up the molecule,' Botte told Chemistry World."

"Botte believes the technology could be easily scaled-up to generate hydrogen while cleaning up the effluent from sewage plants. 'We do not need to reinvent the wheel as there are already electrolysers being used in different applications.'"

It makes an estimated 1kg of hydrogen, providing energy equal to that from a gallon of gasoline, for 90 cents.

But we have, for several years now. We can write a whole new life-form with the right equipment, and time.

In fact, we even made a completely alien lifeform that never used the usual methods life uses on Earth.

And while you might think those experiments were designed, they were designed specifically to run at a quicker pace given our understanding of the conditions on early Earth.

Here is one link from a recent one

None of the reactions described in the video should take even a year to complete, given the right starting conditions, let alone 100 million years.

Each reaction doesn't take much time to complete.
Evolution from self replicant bubbles to self replicant bubbles with some self replicant molecules inside to self replicant bubbles with self replicant molecules inside doing somenthing usefull to self replicant bubbles with self replicant molecules doing a lot of usefull things would take A LOT of time.

We have made self replicant bubbles and self replicant molecules. We have made the basic blocks to make them. Now all you need is some millions of years with trillions of those reactions all the time (ocean is a big place with a lot of reactions all the time)

One step closer to an artificial nerve cell Anonymous 07/7/2009(Tue)04:39:06 No.102668

[Reply]

The methods that are currently used to stimulate nerve signals in the nervous system are based on electrical stimulation. Examples of this are cochlear implants, which are surgically inserted into the cochlea in the inner ear, and electrodes that are used directly in the brain. One problem with this method is that all cell types in the vicinity of the electrode are activated, which gives undesired effects.

Scientists have now used an electrically conducting plastic to create a new type of "delivery electrode" that instead releases the neurotransmitters that brain cells use to communicate naturally. The advantage of this is that only neighbouring cells that have receptors for the specific neurotransmitter, and that are thus sensitive to this substance, will be activated.

Lightning Ball 07/5/2009(Thu)04:42:10 No.12142

[Reply]

Ball lightning may be an atmospheric electrical phenomenon, the physical nature of which is still controversial. The term refers to reports of luminous, usually spherical objects which vary from pea-sized to several meters in diameter. It is sometimes associated with thunderstorms, but unlike lightning flashes, which last only a fraction of a second, ball lightning reportedly lasts many seconds.

Every generation thinks they will see the end of times. In Bible Peter said �the end of all things is near.� He said this about 2000 years ago and people still think that the end is near.

People like to think that they are special, they don't want to be just more one generation. They can't be the first so at least they want to be the last.

Centipedes? In my chan?
It's more likely than you think

This thing is HUGE!

Scolopendra gigantea, (also known as Peruvian giant yellowleg centipede and Amazonian giant centipede), is the largest representative of the genus Scolopendra, regularly reaching lengths of 26 cm (10 in) and can exceed 30 cm (12 in). It inhabits the northern and western regions of South America and the islands of Trinidad, Jamaica, and Hispaniola. It is carnivorous, feeding on lizards, frogs, birds, mice, and even bats. It is also known to prey on tarantulas. The body consists of 21 to 23 segments which are coppery red or maroon in color, each with a pair of yellow-tinted legs; the legs are adapted for fast walking. The centipede has modified claws called forcipules which curve around its head and can deliver venom into its prey. The extremely potent venom, containing acetylcholine, histamine and serotonin (pain mediators), proteases and a cardiodepressant factor, is toxic to humans and causes severe swe

I was going to ask about Hawking Radiation, about how can something escape a black hole, how something can be faster than light and all that.

Instead of asking them to you people I searched for information and got this:

Hawking predicts that black holes emit radiation. This theory is paradoxical, as no radiation can escape the event horizon of a black hole. However, Hawking theorizes that due to a quirk in quantum dynamics, black holes can produce radiation.

My only problem with the whole "Hawking radiation" thing is it demands the virtual particle that falls into the blackhole to be destructive to the mass. In the "real world" an equal amount of "positive" and "negative" virtual particles would be falling in, cancelling eachother out.

The particles are like matter and anti-matter made from "borrowed" energy from their surroundings. If half of them goes away and half fall you will lose energy and mass with the one going out (even light have a small amount of mass)
