The thing about energy is that its practicality all boils down to energy density and power output
10 kW is about 13.5 hp. From an entire roof of solar panels. That's not even enough to run the air compressor in my garage. The same energy output over one hour is stored in 1/4 gallon of diesel. Compared to other energy sources, even intermediate ones, the energy density of solar power just isn't there.
At the sun's zenith, sunlight will produce about 1kw per square meter. My Honda Civic will make 110 hp, which is about 82kW. Assuming we can build 100% efficient solar panels (a physical impossibility), that means it would take 82 square meters of solar panels just to generate the same amount of power. At 882 square feet, even at 100% efficiency, that's just not practical for continuous power generation. Not to mention the best solar panels now are only 25% efficient, needing 4x more area.
With the addition of batteries, the practicality goes up a bit, but only for intermittent power usage. The largest battery Tesla has is 85kW/h. So parked inside a 200 square foot single car garage (18.5 sq m), using modern solar panels, it would still take 9 hours of full sunlight to recharge half the battery. This limits driving to less than 150 miles and only every other day. And as the energy density of batteries increases, using solar to charge them will become even less practical.
Not bagging on alternatives to fossil fuel, but solar is not a viable alternative.

No battery nonsense.
While electrolysis and hydrogen fuel cells are good for storing energy, the energy density of sunlight is just too low to be practical for transportation or anything other than electrical grid support. No matter how you store it, the fact is that sunlight can not generate all that much power in a short period of time.
I agree with you on hydroelectric power, that shit is p cool. Take a lot of foresight to plan correctly though.
Fuck you all, I'll take my 5.7L V8...
On a more serious note regarding fuel: hydrogen peroxide. Blast it onto a [platinum, I think] catalyst and it decomposes exothermically to the tune of over 900 degrees celsius with a 98% pure mixture. You rig the plumbing to build pressure, then release it on a turbine and bam, usable energy in the form of electricity. The products of the reaction are water and oxygen; you could even set up your engine to be variable open or closed loop so that it re-heats some of the resulting water in an effort to maximize energy usage and expels the unusable water out of the tailpipe.
Sure, you still have to create the peroxide somewhere and that somewhere uses energy as well, but I say we consolidate the base energy generation to stationary, renewable sources. On that note, a decentralized grid where every building has its own solar collectors (parabolic or photovoltaic...whatever works), wind traps, or hydro-facilities where applicable would be a much better way of creating electricity than the unreliable centralized grids used all over the world, let alone in the USA. Think of it like socialist electricity...glorious.
With respect to the original post, dealerships were around before manufacturers were selling their cars on their own. The laws in place are there to protect the established businesses (which is already a joke). However, since Tesla never had any pre-existing dealerships before electing to sell direct, the laws don't apply to them. It's causing the dealerships (not selling Teslas, mind you) to cry foul, which is of course bogus.
Who says it has to be one or the other?Quote:
