Bit coin has quite a bit of that [hard coded limits] in the original protocol to be honest. Like no ability to do anything faster, no able to handle even a small percentage of what paypal/visa/mastercard handles per second. It was an experiment that worked too well and now they are stuck with something that wasn't quite fully thought through.

We have been working on grid energy storage for well over 30 years. And we still don't have a solution. What evidence do you have that it will be solved in just a few years? And well i don't think you understand the scale of energy needs. Right now there is no way in hell you could replace base energy with solar or wind or both even if all you do is build solar and wind in decades let alone a few years. Since you need a fuckton of it *everywhere*. Really run the numbers.. http://www.withouthotair.com/

Err no its not. Lots of old nuclear use pretty cool hot side, like around 300C, so to produce a GW of electrical power they pump out 3-5GW of heat. It is well within normal industrial scale cooling capabilities. Old coal was like that as well. These days we push for higher hot side temps, which costs far more up front, but uses less fuel so hence long term savings.

This thing has by requirement a very hot hot side. The primary circuit won't run that hot, but having in the 700C range is not out of the question. Even modern power plants (coal or gas) often use 5% to 10% of the energy the generate for there own operation. 20% is clearly higher than that and often 10% is often quoted as the required figure for commercial plants, but you don't need some other costs to shift to move that up a factor of 2.

Oh FFS. HFT doesn't do shit to liquidity... because to trade at high frequency the stock already has to be LIQUID. And since fucking when is liquidy defined in microseconds. In the good old days when it could take a weeks to sell a stock (and this is still true for low volume stocks, and HFT won't touch those) sure improved liquidity was a good thing. But not when your talking seconds. In fact anyone who starts taking about improving liquidity over seconds clearly doesn't understand the concept.

And on top of all that HFT is reserved for special people. If it was soo good for the market. We would all be allowed to do it. But we can't because its BS.

Help! I'm trapped in a PDP 11/70!
