Agreed. Solar and wind are much under utilised sources of energy. But it is growing, albeit slowly, but growing. I wish we could store the energy generated in lightning storms - just imagine! Or the energy from tornadoes or hurricanes...
Fossil fuels have a limited span - they will run out, not now, but in the foreseeable future.
We are not meant to get political here (although I don't believe this is actually political), but I am a big believer in much of what Al Gore had to say in An Inconvenient Truth. And, well, look at the world's weather profile and events at the moment and over the past few years. Have the scientists got it so wrong?
the only issue i have with wind power is the design. birds often fly into the fan blades of the usual wind turbine and frankly they are not very esthetically pleasing to the eye. Recently I saw testing being done on a water turbine of pretty much the same design. am curious if fish have the same problem. Solar is okay but very expensive to set up and requires alot more then just the solar panels and an inverter. hydro power rocks and can be fairly cheap and easy to set up. water rams require no power and push water uphill. several vids here:
DC, the problem with arguments such as Al Gore's is that they're offered by people who believe history started at 10 o'clock this morning.
The fact is, these things are cyclical in nature, and, periodically, the Earth readjusts itself. These adjustments include greater seismic activity, more rapid movement of the tectonic plates, and changes in weather patterns among other things.
Something else to consider: The particulates and "greenhouse gases" spewed into the air by one really good volcanic eruption surpass all of those put out by humans in the past century. If you want to learn what volcanoes are really capable of, read up on the permian extinction. We weren't even around, then. So, alas, the hand wringers can't point their fingers or cry mea culpa.
But you don't have to think in terms of deep time to be aware of these cycles. They've happened often during the course of recorded history. Do some research, for instance, into the so-called "little ice age" of the middle ages.
And, just as an aside, in the U.S. right now, where temperatures are averaging as much as 20 degrees below normal in many locales, I notice that nobody is talking about global warming.
what we really need is a better battery to store and transport energy without the wastes and bulkiness that we have now.:thumb: hope that wasn't politicaleace:
Gunner, the only thing political about that is the politicians who make self-serving decisions; such as the last major energy bill that effectively decreed research funds would only be available for what is probably the least efficient method of producing fuel, and which had a negative impact on much of the economy.
You want a better battery? Ask yourself why fuel cells are so expensive. We're talking about a mature technology that was developed in the earliest days of the space program. And yet, in practical terms, they are non-existent for use on Earth because they cost too much. Could it be that politicians have a vested interest in not seeing them adopted.
In a similar vein, why aren't there inertial guidance transponders built into cars to prevent accidents? Talk about a mature technology. Inertial guidance systems were developed more than 50 years ago so some general could drop a missle into the pickle barrel of his choice half a world away. There is no reason for them to cost what they do.
Thanks for the tip re the Little Ice Age. I hadn't realised such a thing had happened. The sites I've viewed talk about its effect on agriculture and population shifts, which is what seems to be happening now, in the terms of which land is arable and where crops are failing (something I've thought privately for a long time).
I know the ice ages are cyclic, roughly coming at 10,000 years. But if we can help the environment.....well, can it hurt ?
In depth studies were done here about wind turbine bird kill. It was found that the older generation of turbines that used lattice style towers were the culprit. The towers provided nesting spots and attracted the birds. The modern tube style tower has fewer bird kills than glass windows cause. They aren't a potential nesting site. I live 60 miles from one of the USA's bigger wind resources
DC, I used the Little Ice Age as just one example of many. In that case, the causal effects were shorter growing seasons. Crops couldn't ripen, and people starved and moved away; which, in turn, impacted on other peoples.
If you look at the history of human migrations, most of the time they had to do with food supplies. War, pestilence and disease were other reasons, but many of them were either the cause of the shortages or the result of them.
It's always amused me how little attention is paid by history teachers to population dynamics. Yet, they are a primary cause of history-making events.
I know the ice ages are cyclic, roughly coming at 10,000 years.
And something the junk scientists and political hacks who are capitalizing on "global warming" don't want you to know is that ice ages are always preceeded by a global warming trend. Essentially what happens is as the atmosphere warms you get more evaporation from the oceans, which falls as snow in Arctic regions. The weight of the snow then squeezes the ice out, like toothpaste from a tube.
An argument can be made (and, in fact, is by some geoligists) that ice is a more normal condition of the northern hemisphere, and that we're currently in an inter-glacial period.
But if we can help the environment.....well, can it hurt ?
No, of course it can't hurt. So long as it's done for the right reasons, and with an understanding that 1. human beings are part of the environment, and 2. that there is a synergism between all living things. And that we recognize that politicians and activists have agendas that may or may not actually represent their stated goals.
