240V 30A circuits for electric clothes dryers are common in the US. 50A circuits for welders and 200A main disconnects also not uncommon in residential buildings.
*misspoke. Split phase, not three.
Most cookers in UK run off 30A sockets, anything else usually goes to 3 phase. I regularly run a welder off the 30A cooker socket though.
You have to ask? Do you have $150,000 dollars to plunk out? I sure don't.Why the eye roll?
Odd this came up.If you want the ones that are only as quick, or just a little quicker, with over 200mi range, then it's: $63k for the sedan, $68k for the SUV, $35k for the compact
Indeed, the only real use for the solar array on a car for its too keep the car cool or warm without wasting energy from the main battery.Greg Locock wrote: ↑23 Jun 2018, 01:46Over a year my 5 kW rooftop system /averages/ about 20 kWh per day. So a 500W system which is about as big as you could fit on the roof of a car would be expected to get 2 kWh per day, on average. But the ones on my roof are correctly oriented for latitude and bearing, they don't point straight up. That knocks at least 30%, and more likely 50% off the energy generated, latitude dependent. Then add the need to always park in view of the sun (not a wise move in Australia).
So overall a solar panel on the roof of your car might give you 4 miles of additional range per day on average, using typical Tesla 300 Wh/mile. In summer, in Australia, you will lose more than that because you'll need to run the AC full blast for 10 minutes when you get back in the car.
You may think that is a good investment. There may be some edge cases where it is a good idea, but frankly it ranks as about the stupidest idea I have seen proposed apart from putting windmills on the front of the car that drive generators. (Frequently suggested by 10 year olds, they have an excuse).
I had solar panels on my boat and while not spectacular meant the batteries were extended form a few days to a week, and that was several generations of cells ago.
Obviously it could be done it's just a question of is there a business model for that. My opinion is the EV world won't look too dissimilar to our current petrol world. I think you'll have the fast charging stations for charging rates of hundreds, maybe even megawatts in the future, and then trickle charging at home. Perhaps some larger business will provide slower charging points for their employees but I doubt we'll be see charging points at every spot in at something like a super market.Big Tea wrote: ↑23 Jun 2018, 11:47Example, the parking in the sun in Australia. A roofed parking slot with solar panels? car is shaded and charged?
Yes, it would have to be done commercially, but someone making money from carparking is hardly new, and if you get enough charge to cover your trip home, all the better.
Then again, perhaps your namesake will happen and solve all our problems (would be nice, but don't hold your breath)Cold Fussion wrote: ↑24 Jun 2018, 18:17Obviously it could be done it's just a question of is there a business model for that.

more than 100 years ago some one wanted to provide wireless power to the masses
