Re: Wind and Solar vs Coal, Gasoline, Nuclear

There is no economy if there is no reliable energy. Look farther ahead to what they will need and realize it takes immense amounts of liquid fuel and concrete and time to build out big projects like hydro.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

I don't believe I'm alone in thinking we'd be better off with another Yosemite than with another dam. Depends how realistic and pragmatic you are. And aware. I guess. It's easy from where you (all of us at current) are sitting. With any energy (food, clothing, shelter, employment) need currently me...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

I'm sure when the hydro dams were proposed there were critics who said it wouldn't work/would be too expensive/too intermittent/that we'd never run out of coal. Hydro power rocks! It must be developed where ever it is even marginally feasible and any ecological or social issues opposed to it's buil...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Is it possible that the situation with the privatised energy market in two Australian states is not representative of the whole world? For that matter, how did Tasmania do during the same period? What Tasmania does, or doesn't do, for electrical supply pricing is pretty much irrelevant to any discu...

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: Wind and Solar vs Coal, Gasoline, Nuclear

The 100 year hydro power of TAS is not "RE" in that context of what he was presenting and we all need to get away from lumping solar + wind together with hydro and biofuel in the media and in these discussions.

Nope. Hydro is RE whether you like it or not. Yup. I do like hydro. I don't like green washers intentionally misleading the gullible masses by constantly quoting "RE" "success stories" of locations with small population densities deriving a high "percentage" of their miniscule electrical consumptio...

I see the same type of intentional misrepresentation ...

Too bad it seems like this system is better suited to light commuting in a crowded urban streets than to any serious use by bike enthusiasts. Too many early failures.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

ThorCon Molten salt fuel mixes at near atmoshperic pressure are the way to go for using a Thorium mix. The Moltex SSR design is also based on this and will beat them to market by a decade but is more optimised to burn reprocessed high level waste or depleted Uranium which we have already. .

Re: Wind and Solar vs Coal, Gasoline, Nuclear

It's hard to really know what the true cap cost of any project is. Most projects don't even list them. $2B for that Shepards flat wind farm seems a bit low but that's what Wiki says.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Shepards Flat wind farm in Oregon is 845 MW nameplate for $1.9 Billion = $2.2 / watt. Pretty cheap. But it is only doing 27% so the real cost is $8.1 / Watt and there are $3.4 Million / year in land use fees so $2B over 25 years. If it makes 2,000 GWh/ year that is paid back over 25 years at $0.04 /...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

I just noticed another stat on the wiki for Solar Star PV farm where they differentiate nameplate Power at 747 MW and nameplate AC at 597. It averaged 171 MW for 2016 which is 22% of the nameplate panel rating. It is running at about 13Wac/ meter. The offshore wind farm I found data on was at 31%, w...

Re: E-bike restricted trail access and hate

It brings a good point. Most commercial e-mountain bikes are going to 2.8-4.0 tires running low pressure. The extra traction and contact patch will tear up the trails less.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Does all of the steam from a thermal plant have to pass through the turbines all of the time or can some of it be controlled to regulate voltage and frequency? Balancing instantaneous demand is nothing like maintaining a high percentage of non-intermittent generation to back up RE when the wind didn...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

I guess if I wanted to quote the sale price and include the 55% federal and state rebates I could go around saying roof top grid tie in NY is currently $0.65USD, 0.54 Euro / W for the parts all included.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

c-Si modules cost 0.50-0.60€/W for small systems, small inverters cost 0.15€/W, rest depends on your roof and length of cables needed. You usually do not have to pay VAT for your home PV system. (and you don't get VAT for the electricity you sell to the grid) Installation usually takes less than on...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

In more sunnier regions large solar PV plants can now produce electricity for less than 3ct/kWh I see these numbers repeated here constantly but there is never anything to back them up other than many biased articles in solar trade magazines.

Re: Wind and Solar vs Coal, Gasoline, Nuclear
