What Happens When Hope Takes Over Planning
|
I guess the plan is to store additional gigawatt hours in battery storage. That only works if you have additional gigawatt hours that can't be used.
They shouldn't have shutdown their nuclear power plant. I say it's what happens when political science majors and social justice warriors make engineering decisions. |

The will power to improve nuclear is a need but we keep messing with large energy wasters and pie in the sky. Too bad so sad, have fun with half days of power |
Solar normally works great for peaking. But you have to be prepared for unusual circumstances or the only possible outcome is blackouts.
I say put solar on homes, it blocks some of the sun off the homes roof too. I think any large scale solar should be put on roof tops first, give the power to the people. |
Does anyone remember when we agreed that people should install solar water heaters before solar panels?
|
That's when panels were $3 or $4 a watt.
I'm actually watching a few different solar water heater setups on evilbay and I will probably pick one soon. No one thought premium PV panels would be made in the USA for under $1 per watt. In at least some municipalities you can do solar water heating and you won't have to get engineering plans approved by the state and inspected. It's pretty easy to DIY some plumbing. |

Just having a wind powered ventilation system is a start. Space and water heating. An electrical microgrid if in a Democrat-run state. |
The duck curve:
https://www.youtube.com/watch?v=YYLzss58CLs Now how to shift energy from noon to evening, or demand from evening to noon? Energy for hot water can just be stored in the form of hot water. Cooking on the other hand need too high temperatures for that, maybe hydrogen is the solution here, the beauty of using it for cooking is that you don't need an expensive fuel-cell like when using it for electricity storage. And since you don't need small tanks like in a car, lower pressures can be used and a lot of the waste with compression can be avoided. And the McMansions with low thermal mass, black roofs and huge interior spaces? Perhaps it's time to admit that they were a daft idea all along. We instead need houses with less interior space, with more thermal mass, that are white and even mirrory from all the angles that the sun sees them, that are more connected to nature - and by nature I mean all the free thermal mass of the ground. |
When you get a bad duck curve you have to disincentivise the use of solar that peaks around noon. Have to get people to put in south west facing panels which will shift more production to when most solar installs are dropping out, but overall will produce less power.

EV West campaigned at Bonneville and they partnered with someone who brought a trailer with a solar tracking system. Flatten the curve.
North-South oriented vacuum tubes silvered on the bottom don't require any tracking, for heat anyway. The thickness of masonry can be adjusted for the climate. From another decade: www.bizjournals.com: Cloud goo inventor on a mission to save the world Quote:

Don't the most effective panels rotate on multiple axes?
|
I'll try to remember. It's an array kind of like a Portal floor that deforms to make a parabola that follows the sun and converges to a stationary point.

The real problem is people and businesses shifting peak power later as compared to historical. In yeah olde times the power demand from 5-10pm was much lower than today and the demand curve was much different (even 20 years ago peak power was earlier) So the answer to the problem is to (as a population) get people to wake earlier or much later and alter business hours. My guess is pricing plus unpopular policies could motivate some interests to alter their hours of operation to kill the duck. |
Does the curve account for night-time recharging of electric vehicles?

Quote:
Most with EVS and solar I know either charge mid day during peak solar or set the charge timer for super off peak late at night to avoid fees. Also Given EVs are such a small percentage of vehicles (under 3000 statewide) in my case you would expect to see different usuage patterns in non Bev states versus the 2 or 3 with Bev states that have around 1% passenger cars plug in. But you actually see very little difference between states with and without EVs there is a seasonal difference in states with real seasons and farm usuage is different but nothing due to plug ins yet. One would hope Most plug in users would chase pennies by offsetting use But some states (like mine) penalize you too much for you to break even. |

The simplest thing is the solar pond.

A pool in the sun can gain heat. But if you have a pool that has to have a filtration pump running anyway, and slap a solar panel in as part of the return plumbing, then you can really gain heat. Passive solar is important, but optimizing what's already happening is better.
|
Can't swim in a solar pond. :(
Do you have the space for a roll-away pool cover? |
Why not? mine's a saltwater pool. Is a solar pond just an inefficient way to generate electricity, or do you get some direct gain from the heat? It'd be a pity to miss out on that.
We've got a sheet of bubble wrap that we roll on and off the pool as needed. This sheet has been on it for a few years, this or next year may be its last. |
I post links so you can find answers. Try https://en.wikipedia.org/wiki/Solar_pond#Description. You'll see that it works by stratification, any mixing would kill the 2% efficiency.
The cutt-and-bleeding edge of tech is a membrane to separate the brine and potable water. |

Doing a 2 axis tilt at least triples the price of the panels and mounting in a solar install. All to get about 30% more power. You've better off just installing 30% more fixed panels. It made sense when panels were over $10 per watt. |
Fixed panels with Fresnel lens concentrators.
|
If you direct anything more than natural sun light on panels it voids their warranty.

I don't know if panels could be built to take concentrated solar, but their cost may exceed benefit. If you double the sun on panels do they need a cooling system?
Heat sinks on the underside, or liquid cooling, well that at least doubles the price. I think a good compromise would be to tilt them on a single axis. That way you get a 2 fold benefit. They come up to full power earlier, produce some more power but in thing the real benefit is to be able to tilt the panels away from hail and wind. Since places that have the best sun tend to have bad wind and/or hail. If the system saves the panels one time in 20 years it pays for its self. |
