It's not so bad. Less than pumped hydro and conventional batteries and at grid scale. Combined those are big pluses as pumped hybro can't be built anywhere and batteries are not suitable for grid scale. The question is, what are t

According to their website it looks quite early stage/small scale/experimental. Anybody know how far from feasible and commercial scale they are? In the case of the OP, even they are at least 5 to 6 years out according to the foun

HE is just an example, the other transit providers will match and beat those prices at wholesale scales. For an ISP the wholesale rate is the same as the DC rate. We are not talking about individuals buying retail bandwidth here.

Allow me to enlighten you: Price discrimination is ok, if it in addition to providing a premium product also makes the good or product more affordable and available to another class of customers, thus creating a consumer surplus. Classic ex

by al_bundling 12y ago
Price discrimination is only ok if it increases consumer surplus and you have a choice of providers. Comcast fails on the former and more often than not on the latter.

As I said, ridiculously expensive. Nothing inherently wrong with usage fees, as long as they are fair. That being said, usage fees on a consumer broadband product is a really silly idea if charged at less than 10x wholesale rates as we are

Not everybody wants to be an ISP. Not enough profit in it to make it worth it for the manager. Lack of backhaul and/or cost/difficulty of connecting to backhaul. Existing long term contracts of tennants. High turnover of tennants.

Like that's going to make a difference or not. Comcast is going to charge you for Netflix bandwidth regardless of it coming from a local cache or not.

Equipment, cables and materials still cost the same, so the comparison is relevant. Even adjusting for PPP, the difference is striking. And to explain the differences, you have to look at external factors, such as competition and regulation

I'm sure there's going to be a fair bit of complaining as time goes by and normal usage grows but caps stay the same.

My bad, I misread your point, but in hindsight it's quite obvious what you meant from the context. Wording was a bit ambiguous tho.

That's too bad. You could check out the Google spreadsheet at Whirlpool with all Australian mobile plans to see if you can find a better Telstra plan or one from another provider that uses Telstra's network. http://foru
