I don't think you understand how electric motors work/forces accelerating a car work
Acceleration is a product of power, not torque. (At this point someone will shout F=MA, or A = F / M). I am talking in terms from the engine/motors perspective.
With the right gearing I could produce with a hand crank the same sort of torque at the wheels that any car engines does, but I would not be able to accelerate a car from 0-60 in 5.6 seconds. I simply don't have the power (torque * rotational speed). Using a less powerful electric motor, with different gearing won't make up for the loss of power. Electric motors are power constant devices, rather than torque constant like a traditional dinosaur burner, that is why electric cars don't have a gearbox, and just have a torque converter.
The 0-60 time is more to do with electric motors producing peak torque at 0 rpm. In top trim according to wiki the Signature performance version produces 310kW (416hp) and 600 Nm! (443 fb-lb) of torque. To put that back into petrol engines, a naturally aspirated engine getting 100 Nm per litre is quite a feat. So this motor is producing the same sort of torque as a well tuned 6 litre V8.
Electric motors compared to a normal engine has very little friction and other overheads. I can't really see how fitting it within an motor with half the power/torque would actually save much in battery, a powerful motor does not necessarily mean its inefficient at low power settings. Being lead footed in the Tesla S is going to do the same to your economy as being lead footed in a BMW 3 series or Cadillac CTS. At least the Tesla S can recover some of its spent energy with regenerative braking techniques. Bare in mind, this is an expensive luxury car, and it needs to compete with those other sports/luxury sedans in it's market.
I got my game initially crowd funded. If you are worried about something happening to you and being unable to finish a project, that just says to me: "I am not really committed". If this game is your love and your passion, the money is to help you concentrate on this passion, and you will finish it. If it is just something you like doing, it is not really enough. If your worry is about being hit by a bus, shit happens, deal with it.
Next up, if you are serious about crowd funding, and want to get a large amount of money (i.e enough to live on for a year or 2, hire some contractors for work outside your skill set). My 2 bits of simple advice are, build a community. Crowd funding is about getting the community to help you make a game that they want (both you and your community should be wanting the same game). Don't just put it on kickstarter I hope they come. You need a community first. My second bit of advice, is if you are an unproven games developer, build some sort of vertical slice of the game, to a high standard. (E.g. a demo of just ship to ship combat, nothing more.). This is to show case you and your team (if applicable) skills, to help build trust that you can produce this game.
Wouldn't it be simpler to get an old Android phone and use google Latitude? It seems you can get old Hero's for around $80, create a google account, install Latitude, add your Bike/Car as a friend to your android phone and your done. Buy a cheap 12v cigarette lighter to usb converter, take it apart and plumb that into the wiring of the bike/car to keep the phone charged. Find somewhere to hide/stash it with good clear access to the sky (so under/inside some plastic trim).
Still need to pay for each month for a data connection, or in here Australia there as prepaid mobile internet plans that allow you to buy 1 gig of data that lasts for a year for $15.
Well, if you read Jalopnik, a Japense Mazda top brass has tweeted that they are developing another rotary Engine. So the lack of a rotary in Mazda's lineup should only be a temporary situation.
Its the same or even less complexity as an Apollo mission:
Apollo Mission Steps:
Launch from Earth,
Do a burn for an orbital insertion
Do a brake burn to get into lunar orbit
Land the Lunar Module
Take off from the moon, dock with the command module
Do another burn to come back to earth
Enter the atmosphere at the correct angle
deploy parachutes
Hit an ocean
Curiosity Mars Mission:
Launch from earth
Do a burn to Mars
Enter mars atmosphere
Deploy parachutes
Land using a lunar module esk lander.
It has quite a few less steps.
Not really, the amount of physical cash (coins and notes) is a small percentage of the worth of an actual currency. All big purchases are done electronically. I don't know what it is for Canada but according to this article: http://ezinearticles.com/?How-Much-Money-is-There-in-Circulation-in-the-UK?&id=4292132 Within the UK there is 44.9 billion pounds of notes and coins, but the total amount of money in circulation is estimated to be 1.9 trillion.
I have a multimonitor setup for gaming, 3x1280*1024 displays. Using a Triple Head 2 Go. It works pretty well, the other that is not mentioned in the summary is that Directx9 has a back buffer limit of 4096. DirectX10 has a much larger backbuffer support (I think upto 16k), OpenGL I am not sure about.
By utilizing three monitors, games can become roughly 3x more demanding, as the graphics card is required to render an overwhelmingly higher number of pixels
Anyway, the extra pixels is not what stresses the video card, turning AA to 4x or 16x effectively makes the graphics card renders more pixels but does not have the performance impact an increased FOV does. The increased FOV causes more Draw calls, culling overhead etc as you see physically more. That is what really hurts the performance. The extra pixel area of the back buffer is negligible to performance compared to the extra draw call overheads.
But coal powerplants cause up to 13,000 - 30,000 premature deaths per year in the US alone (quick google) and in general emit more radiation over their lifetimes compared to nuclear because of the trace amounts of uranium found in coal.
Even with this accident, Fukushima has killed less people than a coal power plant of equivalent age. Fukushima is 40 years old, things have improved a lot in reactor designs in 40 years. If it was a modern pebble bed based reactor it could not have a meltdown, cannot expose any nuclear fuel as it is physically impossible because of the design. I also find it kinda amusing that Switzerland has put its plan for a new nuclear reactor on hold. A place that was choose as it was stable enough to partly hold the Large Hadron collider, has no coast line so free from Tsunami's, free from almost all common natural disasters (Hurricanes, Cyclones and Tornadoes) but its plans on hold because of a disaster it can never have.
horse power is a misleading gauge of power, torque is what turns the wheels.
That is wrong in soo many ways, power is produce by a combination of torque and rev's. Torque is not a measure of power, it is a measure of force at a distance. A person can produce a lot of torque if you give them a huge lever. The amount of power a person can produce is always the same.
Horse power is not a misleading gauge of power, IT IS the gauge of power. When you see an engine described at making x amount of torque @ x RPM, e.g. 350nm at 3500RPM this is actually just giving you how many kilowatts it makes at that point, which is 128kw. (350nm * 3500rpm / 9549 magic number). 350nm is just how much force the firing of the pistons are making at that point.
Is the reason I am going indie, It is my ultimate dream to make a living from games I love making. I know a few indie devs here in Melbourne, for some it is their day job, for others they still need a stable part time job to support themselves, and for most its not the money (although) that is nice. It is about the quality of life.
Typed on phone so apologies for bad grammar.
Someone who is write on the money. The cards are crashing due to inadequate case ventilation. Stardock got the same issues with GalCiv 2.
I fail to see how rendering a scene at a high framerate would be any more challenging than rendering a complex scene at a lower frame rate. Remember that the hardware either is or is not in use. The ROPs, the shaders, etc. It isn't like there is some magic thing about a simple scene that makes a card work extra hard or something.
Games now a days are highly threaded, with game logic and rendering happening in parallel and both in lock step (waiting for each other to finish). The difference between a complex scene and a simple scene is that the render thread will have less to update, and do more draw calls. If there is little or no animation to update (either updated in the game logic and pushed across to render thread, or updated in the render thread), no complex scene culling or management, no new assets to upload to video memory, and there is no game logic to handle so the render thread is not waiting on that to complete, a simple scene and simple just turn into a solid list of draw calls with very little update breaks for the GPU to take a break.
The issue is quite simple, stardock had the same issue with galciv 2. There are people playing sc2 who do not play games that fully tax the graphics card as these scenes do, and do not have well ventilated cases, causing the cards to overheat and crash. The issue is solved with a simple frame rate cap. Or the consumer to adequately ventilate their case.
Imagine, going back in time with that card, in its case, to the time of the Voodoo 2.
"Look, I have brought a graphics card from the future!"
*Crack open the case (with added dry ice for the appropriate smoke effects)
"Compared to your puny Voodoo2 with 8mb of ram, this has 4GB! Weighs over 2 kg and requires over 200 watts of power and other fancy numbers. Tremble at it's heatsink!"
Anyway, I digress, I wonder if this card is faster than all the Voodoo2s sold put together?
What I like is how they say, will save the government x amount of money. But they have not spent it. They have not created that money, they just are not going to spend like they proposed. If there was a current games relief tax and they stopped that, that would be saving them money.:S
In the last decade, portable computers have erased many of the advantages that desktops once claimed while desktops have been unable to shake their one glaring deficiency -- they're chained to your desk.
I thought for a while now, that for claims cases like this, the judge should have an "You are an idiot." Judgement. To which the case ends immediately, the defendant wins by default and the idiot gets "Idiot" branded onto their forehead and loses the right to ever make a small claims case again.
