I agree we will never be rid of oil products, like plastic, but at least we can use it more wisely for things that last longer than to burn it up in an instant only to capture a small percentage of the energy in the engine and leave the rest as waste.deronmoped said:Something very important left out of the article.
We still need oil for other things, even to produce the solar panels they are talking about. So the cost associated with getting oil to the market will not go away with solar panels.
Deron.
Perhaps, my take was that if you have a roof full of solar panels, that means you can charge your transportation, similar to what I do with my e-bike. I have solar panels on my roof that charge a battery bank. I use that power to recharge my e-bike batteries, I use my e-bike to travel, errands, food, etc.TPA said:It kinda sounds like this discussion is directed at generating electricity for household needs and possibly some transportation needs, and not fuel for cars and trucks. With than in mind, very little to no electricity is generated with oil.
I'm assuming the article also means non-oil energy companies as well. But, it will require the capital investment of a very large company to build the solar plants needed for industrial use. So will we still be under the thumb of large corporations for energy? I guess not, if you have the means to produce what you need for personal use, and the company you work for produces its own energy.
Just goes to show I know nothing about miningGow864 said:Mining companies have used electric trucks for years. unfortunately, it's the on-board v10 Diesel generator that provides the electricity, in some cases (South Africa) a trolley assist operates on the ramps into and out of the mining pits, almost identical to a regular tram system with overhead lines carrying the electricity. This electricity is made from coal! (Solar alternative for this at least).
it would take a lot of batteries to move a 300 metric tonne dump truck up a 5% ramp, i think that's a while away.

What a wonderful sentiment! I wish he were right, however, I fear that the elite scum that run the planet worship hierarchical domination (the pyramid) and would much rather destroy this civilisation than relinquish power.nutsandvolts said:The Solar Revolution and the End of Big Energy

If you know how much generator wattage is takes to run everything, then you know what you need to replace it with a bank of batteries and solar panels. Great thing about watts, easy to work with the math.
Not so much, Alaska has a battery bank big enough to power one of it's entire city for 7 minutes (an entire city!!) using nothing but massive 13,730 cell NiCad setup.deronmoped said:It would be like trying to power a thousand foot long cargo ship with sails. Sailing, green energy right, sounds pretty ridiculous when you actually start to think about applying it.
Deron.
Stored in a warehouse near the city, where temperatures plunge to -51 degrees Centigrade in winter, the battery will provide 40 megawatts of power - enough for around 12,000 people - for up to seven minutes.

I don't think a 100% wind powered cargo freighter is an inherently ridiculous idea, given enough advances in hydrodynamics, aerodynamics, and lightweight/low friction materials. It's probably not practical in the next decade or two, but it could happen.

Sails would be a redundant system like on the boat you pointed out in Wikipedia, how many extra trained crew members would you need to sail that ship, then you have the maintenance of sails (heavy sail for strong winds, medium sail for lighter winds, light sail for real light winds, spares...) lines, wenches, motors...
Sailing yeah right, you guys need to experience some.

That is a cool idea, I wonder if it worked out the way they said it would?
Still a commercial cargo sailing ship, like they all used to be, is a ridiculous idea in this modern society. I do not know if you guys have ever done any sailing, but you soon find out it is one slow, long way to travel. You would be at the total mercy of the wind, go, no go, slow go, which direction you had to tack to get to where you want to go, storms... I have spent more then enough time bobbing around in a ocean race with no wind to realize that wind power is fickle.
Commercial sailing ships were abandoned a long time ago for a good reason, they suck compared to fast, on time, maneuverable... engine powered ships.

Plus, if you ever have been on a sail boat, the wind can change drastically, at times that sail that was powering you along so beautifully could end up in the water if you were not careful and paying close attention to the wind. On a huge tanker, what are you going to do if you get a big wind shift or the wind dies. You have a huge (6500 square foot) sail up there, the wind dies (or there is a big shift) and the sail is dropping down into the water in front of the ship. Somehow you have to get that sail down onto the ship or you are screwed. You could lose the sail and the lines, or even worse you could run the sail over and be dragging it across the ocean. Then you have to back the ship down and try to free the sail. Or even worse the lines or the sail get into the rudder or propeller. At this point you are totally screwed, you have a crew that sucks and does not know what to do, your out in the middle of the ocean with heavy wind and seas, what a nightmare!

They have proven to work well, just as Paul has been saying, and demand is high for them.
