A serious military drone won't need anything more than a compass, barometric altimeter and a camera for visual navigation. At night it might also make use of a star tracker. All of this can be isolated from any realistic EM weapons. Sure, civilian drones are not going to go to such lengths... for now.
California forestry service does prescribed burns periodically, during the wet parts of the year. But it's getting complicated by the recent dry years - too much of tinder-dry undergrowth and dead trees have accumulated. The windows for safe burns are becoming smaller especially given the vast population of California.
NSA is going to announce a competing keyboard. They're already digitizing everything but now they'll be sending you a copy as a courtesy and for proofreading and correction. Win-win!
Then how about mandatory draft and military training? Why do you want to fondle your guns but don't want to become a part of "well regulated militia"? Remember, some of them even advocated government distribution of standardized weapons.
Can you also post code that reliably mounts filesystems, stops and starts services, handles changing system configuration on the fly and uses cgroups to restrict resource usage?
After all, all this should fit in one post, right?
VTOL pretty much means "helicopters" (we discount military jets with vectored engines). And helicopter manufacturers are stuck in 70-s.
And you can't really make a traditional helicopter cheaper, you have lots of expensive parts because a failure of any of them will cause lithobraking followed by rapid unplanned disassembly. And they can't experiment with multi-rotor systems because the weight of mechanical transmission is prohibitive.
Fortunately, we now have powerful batteries and electric motors. Creating a helicopter or a multi-rotor aircraft capable of lifting a human is not too complicated because of insane power-to-weight ratio of electric propulsion. There are several companies doing just that.
There's still a problem with energy density - it's easy to take off vertically, but the flight time will be around 15-20 minutes.
Incorrect. You can't get more than 6MW from these turbines, the capacity is limited by the mechanical parts (gearbox). And at high winds they actually have to be _stopped_ with blades at minimal pitch and motors electrically locked.
In a couple of years you won't even have to do that. You can drive to Vegas on a Tesla (or a Model 3 in two years) from pretty much anywhere in the US, by utilizing the supercharger network: http://supercharge.info/ . And in a couple of years it'll cover all of the major routes.
We are talking about natural gas, not hydrogen. You can burn natural gas in solid oxide cells but so far none exist that are practical (otherwise all those gas turbines would have switched). And the _real_ (not proposed theoretical) numbers are miserable. See here: https://en.wikipedia.org/wiki/... - that's with cogeneration (i.e. waste heat is also reused).
This is nothing more than a window dressing to greenwash increasing dependency of Germany on natural gas.
Nope. Just google it. Here's EIA: https://www.eia.gov/electricit... - pick the lowest monthly number because you actually have to build out with it in mind.
Power-to-gas has a roundtrip efficiency of about 15% right now. The renewable plan for 2050 will require natural gas generation backup for about 60% of all installed capacity so it's quite obvious why power-to-gas is being pursued. It's a good window dressing.
I've been hearing this since 2000-s and the price for wind did come down. But the cost of offshore generation also is not coming down. There's a reason for this - sea is a hostile environment and turbines have to be built to withstand much more aggressive weather.
The main problem with renewables right now is lack of energy storage, so simply scaling variable sources doesn't work at all. It's looking to be a fundamental problem that can derail the whole transition.
Even in Europe the installed offshore wind capacity is pretty much a rounding error. If we look at Denmark then they have 1.2GW of installed offshore generation with a capacity factor of about 20%. So that's just 300MW of average generation without guaranteed capacity. I.e. less than one block of a modern thermal power plant or 1/4-th of one reactor in a modern nuclear power plant.
It's mostly OK for Denmark because they export excess energy into Norway and Sweden which store it in hydroaccmulating powerplants. But that doesn't scale at all.
So you'll have to re-digitize the wallet each time you want to use it, update the paper copy and then carefully make sure that no copies of the wallet are left on the hard drive. Yeah, it'd work well.

Perhaps grandparent can't write? (I thought that it's impossible but there are people out there who can't handwrite but can type easily)

IntelliJ works fine with multiple projects open at the same time.

The first one. Duh.

6MW is the nameplate capacity, the actual capacity is anywhere from 20% to 40% of that, depending on the local conditions.
There are "human experiences" that I'm glad we have exterminated.
They promise to go all the way to Fairbanks and the routes along the CA-1.

Teslas can recharge at ~350mph. So 15 minutes of charging midway into the 300 mile trip is enough (assuming that you've started with a full battery).

Everyboby except AT&T, don't forget that.
