In one model of heart attack, animals given hydrogen sulfide showed a 70 percent reduction in heart damage compared to those who got the standard of care that you and I would receive if we were to have a heart attack here today.
So, these are the thought leaders in trauma medicine all over the world saying this is true, so it seems that exposure to hydrogen sulfide decreases damage that you receive from being exposed to otherwise lethal-low oxygen.
And I should say that the concentrations of hydrogen sulfide required to get this benefit are low, incredibly low.
One thing those people did out there was take this technology of hydrogen sulfide, which is this start-up company that's burning venture capital very quickly, and they fused it with another company that sells another toxic gas that's more toxic than hydrogen sulfide, and they give it to newborn babies who would otherwise die from a failure to be able to oxygenate their tissues properly.
And I want to say that I think we're on the path of understanding metabolic flexibility in a fundamental way, and that in the not too distant future, an EMT might give an injection of hydrogen sulfide, or some related compound, to a person suffering severe injuries, and that person might de-animate a bit, they might become a little more immortal.
You take about eight or so carbon atoms, about 20 hydrogen atoms, you put them together in exactly the right way and you get this marvelous liquid: very energy-dense and very easy to refine into a number of very useful products and fuels.
What it is, is a picture of the spectrum of hydrogen.
What you're seeing when you put it through a prism is that you heat hydrogen up and it doesn't just glow like a white light, it just emits light at particular colors, a red one, a light blue one, some dark blue ones.
Let's say we converted all the vehicles in the United States to battery electric vehicles, hydrogen fuel cell vehicles or flex fuel vehicles run on E85.
We talk about hydrogen cars.
But come on now, if aliens needed energy and could absorb it from sources like hydrogen bombs, why would they come to earth?
No one in power seems to care about the impact the release of that much energy (which by the film's end includes, among other things, the entire yield of a hydrogen bomb) will have on the surroundings.
However, something positive in this was the visual effects (dragons were beautiful), but some of the information in this mockumentary was totally fake, and that is really disappointing because it was coming from scientists, so that is the reason why it deserves a 1 of 10 and not a 0. An example of false information would be the hydrogen idea: It is true that, according to Chemystry, the hydrogen is produced in the stomach but it is impossible to be produced in that proportions, so in that case, you need a good explanation of what really happens in a dragon stomach.
There are a lot of substances whit hydrogen in the nature but not the necessary to aloud an animal like that to fly, and the hydrogen does not appear from nothing, so it is impossible.
And each one, even the ones going slow, explode like they have a hydrogen bomb in them.
But, in the United States, unlike in Europe and Asia, discussion of hydrogen energy and fuel cells as systemic, game-changing technologies is largely absent.
By now, many have heard about plans by big carmakers – including Honda, Toyota, and Hyundai – to launch hydrogen fuel-cell cars commercially around 2015.
Daimler, Ford, and Nissan plan to launch such cars around 2017.Germany plans to build at least 50 hydrogen fueling stations by 2015 as the start of a countrywide network.
But a bigger, largely unreported, message is that some European countries, especially Germany, have launched projects that combine renewables like solar and wind with hydrogen for energy storage, implying clean, zero-emission, stable power grids that require no coal, oil, or nuclear power.
Indeed, the bottom line of a new study by two American researchers, Willett Kempton and Cory Budischak, is that the combination of renewables and hydrogen storage could fully power a large electricity grid by 2030 at costs comparable to those today.
The results buck “the conventional wisdom that renewable energy is too unreliable and expensive,” says Kempton.“For example,” according to Budischak, “using hydrogen for storage, we can run an electric system that today would meet a need of 72 gigawatts, 99.9 % of the time, using 17 GW of solar, 68 GW of offshore wind, and 115 GW of inland wind.”
Their study lends scientific supportto several such projects underway in Europe aimed at proving that hydrogen gas, converted from water via electrolysis – think of it as natural gas minus the polluting carbon – and stored, for example, in subterranean salt caverns, can smooth out fluctuations inherent in solar and wind energy.
Meanwhile, near Berlin, five companies launched a €10 million ($13 million) pilot project at Berlin’s main airport in Schoenefeld in December, expanding and converting an existing hydrogen fueling station to CO2 neutrality by linking it to a nearby wind farm.
And the world’s first renewable energy/hydrogen hybrid power plant, producing both electricity and hydrogen as car fuel, started production in the fall of 2011.
In fact, hydrogen technology will be an integral part of Germany’s evolving renewable/alternative energy-based system.
Though it probably wasn’t, as North Korean media claimed, a hydrogen bomb, whatever it was – probably a fission bomb – had more than enough explosive power to constitute a serious threat.
The Great Hydrogen HopeRHINECLIFF, NEW YORK – In Jules Verne’s novel The Mysterious Island , published in 1874, Cyrus Harding, the book’s engineer/hero, declares that “water will one day be employed as fuel, that hydrogen and oxygen which constitute it, used singly or together, will furnish an inexhaustible source of heat and light.”
Water, Harding announces, would be decomposed “doubtless by electricity” into hydrogen and oxygen.
Many of Verne’s musings remain fantasy, but where hydrogen is concerned, his time has come.
Two years ago, the European Parliament in Strasbourg overwhelmingly passed a declaration urging a green hydrogen economy.
