Re: Wind and Solar vs Coal, Gasoline, Nuclear

Hydro power rocks! It must be developed where ever it is even marginally feasible and any ecological or social issues opposed to it's build out must be secondary. To demolish any existing and well producing still viable hydro projects is a big step in the wrong direction. As always, people will tra...

Re: The winner is . Not what you think

No, it's the cars and trucks. If the assholes stayed and all the cars and trucks left town, it would be a lot better. So you are just as bothered by your neighbor's car parked in his garage as when it's being driven too close to you on the road? It's the drivers, not the things they drive (or fly, ...

Re: The winner is . Not what you think

By the 1920s, there were tram systems in every city of note. They were bought up by General Motors and switched over to buses, or shut down altogether; or they were closed for lack of profit while roads for cars were being heavily tax subsidized. Those were transportation choices people were exerci...

Some sort of thermal inertia mass system to store "cool" during the early noon hours, instead of storing power, will have to be developed as more solar PV is phased in. And smart grid thermostat control.

Re: The winner is . Not what you think

I'm really trying to think from your point of view... Because as I said, I don't really believe that you think that cars are more efficient than trains. The best I can come up with, is that you're fixated on the weight, because I used a throw away number as an example, and you thought it was key to...

Re: The winner is . Not what you think

Cars were originally for hobbyists only, then for rich fux only, but later for "everybody" (meaning everybody who didn't care about the safety and welfare of others, and could afford one). The fact that Tin Lizzies weren't much heavier than a horse and cart, nor much faster than a bicycle, made the...

Re: The winner is . Not what you think

Our society transformed from agrarian to industrial without cars. They were never necessary, only something that people opted into because they didn't care about the harms they do to others and the commons. No, they opted into them because they were better (easier, faster over a long distance, more...

Re: The winner is . Not what you think

Hmm, not sure if you're being a bit selective with your choice of train. The Warratah trains in Sydney weigh 880,000 pounds and carry 900 people seated, probably around 1200 including standing. Sounds like a modern, lightweight train. Great! But I was responding to your claims about trains a centur...

Re: The winner is . Not what you think

Nothing to do with the efficiency of energy conversion. If trains a century ago were running with only one person in them at a time, yes, I would have said that was shockingly wasteful. Hmm. Modern trains are pretty heavy. A six car Amtrak train plus engine weighs about 1.1 million pounds. Older tr...

Re: Solar Cycle Analyst?

I propose that it would be very useful to purchase a Cycle Analyst that utilizes two shunts; one for solar input, and one for motor output. This way, your bike would be able to accurately display input & output power with one gauge instead of using a second meter. If you want to have one meter accu...

Right. Which is why I'd like to advocate sensible and practical e-bike laws. That should help it not become an issue. Definitely.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

You could build several new fossil fueled power plants for the 10 billion Euro estimated for the N/S grid link. Right. And then you'd have to run a grid link to them for billions more to get the power out of those fossil fueled power plants. Coal power is stuck in a bit of a quandry. No one wants c...

Yep. I'd buy or make a sticker that says 750W , put it on the motor, and point to it if questioned. Cops aren't going to test for wattage. That's one reason that having such technical requirements are bad law. They are impractical to enforce. Not if it becomes an issue; it's simplicity itself. The ...

The whole point of renewables is to save the environment and Germany has done the opposite they are quite literally cutting down forests to install solar farms.
MUCH better than leveling square miles of forest to mine coal, then filling in river valleys with the overburden and tailings.
