Re: Wind and Solar vs Coal, Gasoline, Nuclear

Way too many people right now. Women's education is the greatest aid we can give any country. Would be nice to still have a viable human population running around 100,000 years from now.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

"A" is when all of our modern economic theories were developed which is a very warped view compared to how things always were and how they will be again. . . https://scontent-ort2-1.xx.fbcdn.net/v/t31.0-8/22467545_1475056822573425_3164139082063497167_o.jpg?oh=09e618fd32e29ee48878a3264037cc90&oe=5AD7...

Population, economy/standard of living, food production, marine life depletion from over-fishing. acidification, warming. Acidification and warming have positive feedbacks which can kick...

Re: Pesu TTium mid drive bike cheap on kickstarter

I think this is the first bike I've seen with a 14t front chainwheel, The front is internally geared to 2.8 to give the motor another reduction. Makes it into a 39T when you pedal. Bosch is the same. . . https://www.bosch-ebike.com/fileadmin/_processed_/4/c/csm_Bosch-eBike-Produkte-MY2017-Fahrtechn...

You can comfortably rest assured the grid as we know it simply not even being connected to modern homes, as it will be no significant cost or maintenance penalty to have them all constructed with adequate solar roofing and battery storage.
You must live somewhere it never rains or snows.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Very highly flawed system for electrical storage for which it will be 40% efficient at best if the local site has no use for the other 60% as heat. We seem to do OK with gasoline powered cars, which have a 38% at best efficiency. They might be "very highly flawed" (and for sure EV's fix that flaw) ...

The reason is that the true value and cost of burning fossil fuel is never imposed.
I am in favor of phasing in a world wide carbon tax, right when it leaves the ground. Which could put a true value on it. But how can we do it?

So, with that in mind, system efficiency will be important in order to minimise power costs. The oportunities for $0 cost will be far fewer than demand states. 70% efficiency of pumped salt water hydro has already proven to be too low in a free market. 33% from intermittent electric over supply con...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

The service life of hydro will be at least 3X of batteries if not much more. Saltwater pumped storage will be ideal for many island locations like Hawaii, Puerto rico which are mountains rising out of the sea.
