Re: Wind and Solar vs Coal, Gasoline, Nuclear

And do what for the 18 hrs the sun is not shining ? I think you're starting to lose track of your own arguments.

Re: Tesla 18650 question

..... Assuming my inside temperature is 25C and your chart data, by the end of the discharge cycle I would get 55C which is very hot to touch, 60C is about where your fingers start to burn and you cant keep them on. So data seems to be in line with what I am getting. ... ....i. Doubt it , that is a...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Most Australians heat their homes with electricity? Here it's propane or natural gas. Natural gas is super cheap nowadays.[url][https://www.nmgco.com/Current_Natural_Gas_Rates.aspx/url] There has been a huge uptake of A/C systems througout Australia, such that Reverse Cycle A/C is rapidly becoming ...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

You must not be aware of the Thermal Solar plan for SA. Another $650m or so, for a 150 MW solar tower with 8 hrs of storage. If you do the maths, that averages out at <60 MWh equivalent continuous..if the sun shines 100% ..except in winter when there is not enough sun to run the plant at all !! True...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

[The SA grid needs more POWER (600+MW). for long periods of time ..12+ hrs at a time, often much longer. Which means they need a lot of ENERGY, (7-10 GWh) I very much doubt they need it for "12+ hours at a time." Look at the demand curve; it peaks once, and it's not anywhere near flat. This new 210...

Re: Tesla 18650 question

This is a reputable test (Lygte) of a Sanyo (Panasonic) 18650BF,..very close to a Tesla spec cell...discharged at 5.0 amps.
Even at that rate (1.6 C) it only increases 25-30 deg over the complete discharge..

.....yes..and of much greater capacity. That was my point ! No, you missed the point. If they need ENERGY, then solar or wind or a CCS gas turbine is a great way to go. If they need POWER to stabilize the grid, then BESS makes more sense. Do you understand the difference between energy and power?.....

If one 211MW reciprocating peaker plant makes a 1600MW coal plant redundant then that is a massive gain in efficiency Why on earth would you criticise the capacity factor of a peaker plant?

There is a big difference between wepons grade plutonium and fissile uranium fuel.
But i guess a "dirty" wepon could alway be constructed.

Re: Lithium batteries for Submarines
