Solar Power

Post by maryjane48 »

Shell plans to spend as much as $1 billion a year on its New Energies division as the transition to renewable power accelerates, and will partner with Sunseap Group Pte to invest in solar throughout the Asia Pacific. Equis Energy earlier this month approved a 1,000-megawatt solar plant near Wandoan, a region long associated with a potential large coal mine development by Glencore Plc.

Why Australia? Why not BC? :popcorn:

You DO realize that molten salt thermal storage systems for electricity are A) expensive, B) only 40% efficient on average and C) have been around for quite some time.

Thermal storage systems for solar energy are actually more effective and efficient for heating purposes, not electrical generation. They have been used for a very long time.

This is an example of an effective and cost effective use of solar thermal energy storage: https://en.wikipedia.org/wiki/Trombe_wall that in the context of BC will actually reduce GHGs.

This is more effective: https://energy.gov/energysaver/active-solar-heating, but alas, not very good for the Okanagan as we get so many LCC days.

This is where solar harnessing works well (upper right corner) ...

... Still, even the Nevada desert has limited potential for solar

The problem with mirror collection/salt tower type systems is that they fry every flying creature that bumbles into them. From what I gather there is a "dead zone" around them for pollinating insects etc.

I know they use hydro coupled with solar to create a steady power generation. Basically, the way it works is when it's daytime some energy goes into the grid, and some energy powers small pumps pumping water to a higher ground position. Once the night falls, they start letting water go back to its original position and harness the power of the stream to create energy. Somewhat of a roundabout way of saving solar energy for future use. This way day or night the power is always being produced.

MJ if you followed the site C topic you would realize that I brought up this type of site in Welton AZ a few times, it is nothing new.

Now lets take a look at your link. A billion dollars for 200 MW's for 25 years. That would mean you would need 5 1/2 sites to match say site C project at 1100 MW's. That would be 5 1/2 billion dollars to start with. Then you would need it 3 to 4 times to match the life of site C. 16 1/2 billion to 22 billion to match site C. The only problem is that does not include land, permits, agreement with anyone affected, transmission, disposing of all the equipment every 25 years and on and on. On top of that the difference in the sunlight available between Dubai and BC means it would cost many, many more billions of dollars. In other words the cost would be much higher than that for something like site C. Might be okay for a rich country like Dubai but it would put a jurisdiction like the province of BC in electrical poverty.

The alternative power supplies are not ready for the real world at anywhere a reasonable price as has been proven numerous times.

Sounds exactly how hydro electric works without the initial pumping. LOL Somewhat of a roundabout way of saving solar energy for future use. This way day or night the power is always being produced.

Exactly! who would be stupid enough to build a hydro station that they have to pump water to if they could just build one and have it come to them. It works where it is necessary but it is dumb when it is not. I saw one of these stations in Scotland in the 70's and it was an excellent solution for them because it was the most viable alternative, in fact the only alternatve. They didn't actually create the lake at the top but kept it full by pumping water back up at night when demand was low.

This happens everywhere. Every car manufacturer reverse engineers all competition vehicles to learn what they are doing. The real issue here is Daimler Mercedes appears to have rented the vehicle, tortured it, unscrewed it, put it back together, and gave it back damaged without due compensation.

Reverse Engineering on a budget. Why buy a competitors overpriced car when you can just rent one for the weekend? Good for them.

Same thing happens in the heavy equipment industry. They purchase the competitions machine and disect every inch of it. Seen it first hand and it’s very interesting.
