He quickly became very unpopular with settlers due to trying to be fair to the Maori. In one notable occasion some colonists invaded Maori land in an attempt to seize it and got massacred. (They were a poorly armed militia and on the other side was Te Rauparaha, who was so scary that to this day his haka is used by the All Blacks to intimidate their opposition.) After an investigation, Fitzroy sided with the Maori.
There are many ways to 'store' electricity. Batteries are just one.
I rather like this one, a thermal storage solution. Putting air into and out of bladders under deep water is a very simple method, as is moving water up and down hills. Then there are flywheels and fixed volume compressed air storage. (The air bladders above are fixed pressure compressed air storage.) There other thermal storage possibilities, but getting good round trip efficiency is tricky.
There are non-traditional battery techniques too: flow batteries (liquid electrolytes in tanks, adding storage capacity is as easy as adding tanks full of electrolyte) and molten metal batteries (take the idea of aluminium smelting and make it reversible).
All the non-battery alternatives I can think of work at industrial scale, so if you're looking for a household/small business solution, I think that at least for now batteries are it.
There are three lessons here. One is about arbitrary work requirements, which you've made well.
Second is the problems which arise when vertical integration in your company means that one level's customers are another level's competitors. This conflict of interest is liable to drive away customers. (A company my father worked for many years ago had a similar issue: one branch manufactured and sold refrigeration equipments and spare parts. Another branch maintained and repaired refrigeration equipment, so their competition was the manufacturing branch's customers. The maintenance branch was separated into a new company to avoid this problem.)
Third is when you have a large corporation with an innovative product, that innovative product's potential can easily be crippled by being held hostage to vested interests of other parts of the corporation.
Someone in the Youtube comments says "The flight profile veers the booster off to the side on purpose so the exhaust from the final burn isn't directed at the barge where it could do damage"
If this was a planned manoeuvre, I'm much happier. Can anyone confirm this statement?
I was shocked at how abrupt and extreme the pitch changes were. I think so long as it needs such gross adjustments so close to landing, landings will be unreliable with a significant chance of failure. It is not at all like the tidy landings made by the Grasshopper test vehicle.
Two engineering changes which could make a big difference are lower minimum thrust (so it can approach the landing with lower acceleration) or lateral control rockets (RCS) at the top of the stage.
In addition, big bang nucleosynthesis models place strong limits on how much baryonic (protons, neutrons) matter there can be and it is not enough to be the dark matter.
Because methane is a very potent greenhouse gas.
I'm not sure why you bring flatulence into the discussion at all.
Besides, there is a scientific mystery, so scientists want to solve it, independently of how good methane's rap is.
"... any modern airliner can be specced with options to fly itself from gate to gate on an ordinary day
Can you tell me more about this? My understanding is that taxiing and take off are always performed manually. Unless it surrendered control to a central airport system, I don't see how autotaxi would even be useful, as actions are so dependent on other traffic.
Dumb Americans. Sensible people measure land area in Wales. How many Wales are there to an Oklahoma?
This is word for word the first comment after the original story. However, as both commenters are named "Scott" it may not be plagurism but rather comment reuse.
Of course Minecraft is violent. Do you have any idea how many innocent instructions get executed to make it run?
How about using supercapacitors to convert 5 seconds of 60kW into 15 seconds of 20kW (less losses)?
5 seconds of 60kW = 300kJ. Supercapacitor energy densities are in the range 0.5 to 15 W-hour/kg according to Wikipedia. Say 5 Wh/kg, = 18000 J/kg, so you'd only need a few kg of supercapacitor to make this work. The only price I find is US$2.85 per kJ in 2006, putting the cost at around $1000, probably much less now (but there will also be costs beyond just the supercapacitor.)
You could also make this an option - not much point paying $2000 for this capability if the car is going to be in Singapore.
I can't tell if you're serious.
The idea of landing a stage on rocket power for reuse has been around for decades (DC-X comes to mind, there may be earlier examples.) As rockets generally launch seaward for safety reasons, that you might want to land one at sea is obvious. The idea of using a ship as a landing platform has also been around for decades. There is nothing that should be patentable in the big idea "landing a rocket on a ship".
Within this general idea, there are bound to be many smaller patentable ideas: e.g. method for automatically securing a rocket to a deck when it could be up to 15m away from the target landing point.
Furthermore, that is why rockets launch from the east coast in the first place: if something goes wrong, the flaming debris comes down over the sea.
However, SpaceX are aiming to do a return to launch site for recovering their stage I boosters. (This surprised me - this must use more fuel than land-at-sea, and the mass of that fuel is directly subtracted from your available stage II payload.) The landing at sea is an interim measure while they prove the technology (because of the afore mentioned potential for flaming debris.)
I don't see why not (so long as software patents are allowed), but once you have your patent application, you'd better run the software on it and also submit all the variants it comes up with, before someone else does.
