    About 275M cars in north america. I was calculating based on the report that the average affected VW was polluting over 40 times more than the maximum allowed for a car to be allowed in Canada I have seen reported in the news (and allegedly the US regulations are more stringent). Thus, those 11M VW in the world are emitting the equivalent of 440M of cars that would be at the limit. Notice I only reflected on the cars of NA, not trucks or other sources.

Considering I would expect a lot of people to do that and that only those cars are polluting more than the total of the other cars in circulation in north america, if I was working at any related government agency I would not renew the road worthiness of the cars and requires them to be certified repaired/upgraded before allowing them to be driven again.

I didn't claim a year long average of 200kwh/day, only a winter average of this value ( dec. 21 to march 21). The worst time is usually around mid january to mid february but it can vary quite a lot depending on the years. Also, to have that 'low' 200kwh/day, I switch to a high efficiency wood stove when the province consumption grows to be close or higher than our production. It cost about a third to heat with wood but it's not as clean as hydroelectricity, but when they switch to buy from afar I don't mind the limited side effects of wood burning. But then, I'm not that near to a city - for which wood stoves are very bad when it's very cold.

Anyway, I'll be revisiting the heating source for my property, and I'm thinking about going to a heat pump + propane for the main loop (I'll still keep the stove though). Average daily consumption in the summer is less than 60kw / day (out of which I expect 30+ kw are computers & monitors) so I expect that I could reduce the electricity bill by 9000 kw / year, but I haven't been able to get straight numbers on what to expect to pay for the propane so it's still hard to establish if and when I would pay back the investment.

My floor heating system in the basement is 5kw, my distributed hot air is 27kw, and I have 6kw of extra heating element (convectair). Worst days (-30C down to -45C) the 27kw will be used 20h+ and the other elements will pick up the slack. Thats a baseline of 540kwh for a day. Luckily they aren't that common...

Wow.. In the winter, with the (extremely) cold days that we get I use over 200kWh per day, most of it at night (yes, the shining sun does reduce the load in the day by quite a wide margin with high quality windows). But then the sun is only up for 8 hours and some, and beside it takes an hour out on both sunrise and sunset before it manages to hit the house and lose it early. Not even talking about the bad angle of the sun, it means we would need way too much solar panel to be able to provide for a days worth of energy, and a lot of capacity to store it. And that's not even taking into account that we have a lot of days where we don't get to see the sun at all because of the extremely deep cover.

Lets say we want to be able to provide 3 days of energy without functionning panels (or a bit longer with some energy in), that takes a minimum of 600kwh, or about 95 tesla powerwall units with a 90% efficiency inverter. Where you trolling or do you really think this small battery is a revolution ? Speaking of revolution, I would rather have a large sized flywheel dug somewhere nearby.

I've been a fan of photography for 17 years, and I've taken countless pictures on beaches (and quite a lot of other places!). The reaction all depends on how you approach both the subject and locations. I've seen photographer be roughly handled but it appears I've been doing it well since that never happened to me. Always respect the privacy of the people and they will respect you. Quite often people will even come and ask to have their picture taken, in which case I simply email a link to their private copy.

Sometimes you get a nice shot of a non-descript couple or something, in which case if I get the chance I'll go meet them and present the result, and ask if they want it (free of charge) and everyone has been happy so far.

I recently started playing with a quadcopter, and the result is the same, except that I have much more inquiries and people want me to video them and give them the youtube link. A lot of people where very happy to get to see the world from an higher point and I've received countless thanks for this already.

Also, keep in mind that most drones have a very wide field of view, so you are very small in the video when the drone is still pretty close. About the girl waving, it's entirely possible he was taking pictures of the house/property around, and when he noticed someone he flew out, since you must take all precautions not to fly too near to people.

I've also met other people flying their drones, either custom made, new products being developed or commercial ones and everyone I've met so far were nice people. I find it nice that people get together and talk because of this new subject rather than each of them taking selfies / ignoring everything around. Oh well, your mileage may vary :)

Removing the CO2 is the main point; people won't be spending too much time in there, so there's plenty of oxygen, but the CO2 level would climb quickly. Chemical CO2 scrubber's have been costed at 1K$ per ton of CO2 removed. Since we exhale about 5% of CO2, at an average rate of 10 liters per minute and 1.96 g / liters of CO2, that means that on an hour trip (planned at 35 minutes), someone would exhale approximately 60g of CO2, or it would take 15K people to use up that cartridge. Thus, less than 7 cents per trip per passenger.

How long does a plane take to travel between both places ?

There's barely 560 km between both locations. An hyperloop device accelerating at the same speed a Tesla P85D does (lets say 33 km / h / s) would reach 600 km/h in 18 seconds. And a Tesla does't tend to splatter it's occupant on acceleration. If the environment is stable and safe and the vacuum is tight and the suspension is magnetic, it's easy to think about 2 minutes of acceleration, cruise and rotate the seats, 2 minutes of deceleration (which would feel like 2 minutes of acceleration)

Back of the hand calculations yields a speed of 3960 km/h reached after 66km (2 minutes in), 6 minutes 30 of cruise, and 2 minutes of deceleration. for a total of 10:30 without dangerous forces being used( provided the path is straight... yeah)
