Came to post about FutureTruck. I wasn't in my school's (Wisconsin) group, but I can tell you this - 1st thing to do is to lighten that pig up.
I recall in the early 2000s that they had a local manufacturer donate a hydroformed aluminum frame. I don't even want to think about how much that sucker cost. Since they had the truck apart, they started chucking/replacing other parts.
That savings in weight allows you to accommodate more batteries, improve towing performance, or just improve fuel economy.
If I remember correctly, my school's team ran a series hybrid similar to the parent. They might have had regenerative braking, not sure.
If you are planning to sell this as a kit, replacing the frame isn't really an option. I'd focus on the motor (duh), battery size and location, regenerative braking, and lightening components that can be easily accessed.
What you might want to look at is working from a crossover SUV platform. Unfortunately, those car/trucks tend to be pretty damn heavy too...
There are a lot in orbit a little ahead and behind us, that a phase transfer after escaping earth's gravity would get us where we need to be. Check out this article:
The new frame is larger than the old one - maybe he designed some cushion into it?

Depending on his discipline, the prof would give him a A for unique design, ergonomics, or mass-producability (prototype was 3D lathed, but design could be cast?). Drop test durability would fall under a mechanical engineer, imo.

However, a special prosecutor assigned to the case brought charges against 650 people, which did not result in convictions.[1] Three Chicago election workers were convicted of voter fraud in 1962 and served short terms in jail.[1] Mazo, the Herald-Tribune reporter, later said that he found names of the dead who had voted in Chicago, along with 56 people from one house.[1] He found cases of Republican voter fraud in southern Illinois, but said the totals didn't match the Chicago fraud he found.[1] After Mazo had published four parts of an intended 12-part voter fraud series documenting his findings which was re-published nationally, he says Nixon requested his publisher stop the rest of the series so as to prevent a constitutional crisis.[1] Nevertheless, the Chicago Tribune wrote that "the election of November 8 was characterized by such gross and palpable fraud as to justify the conclusion that [Nixon] was deprived of victory."[1] Had Nixon won both states, he would have ended up with exactly 270 electoral votes and the presidency, with or without a victory in the popular vote.
I should correct myself. The OS itself wasn't crap. The fact that NOBODY developed for it made the experience with the OS crap.
Before Vista came out, we had one machine in our office running XP64. We use primarily Solidworks and they came out with a 64-bit version of their software. Completely buggy and some files weren't compatible with the 32-bit versions of them. Complete fiasco when you're staring down a deadline.
Eventually, they fixed it and now things are seamless. I have more machines running 64bit, but am limited because our stupid VPN can't handle 64 yet...
My experience with installers/programs that don't run in Win7-64:
"Did this program install/run correctly?
Windows detected an unexpected crashing of your program. Would you like to run the program again in compatibility mode?"
Lots of problems solved that way.
If that doesn't work, there's always my dual-boot of WindowsXP I have on my machine, though I haven't had to touch it for months.
Generally, if you can generate lift at low speeds, you generate more lift when you're going fast. At some point, that extra lift just becomes a drag to your plane.
Consider a current jetliner. They employ very complex flap systems to alter the shape of the wing to increase its lift for takeoff and landing. A larger, squarer wingspan will generate more lift, but that lift becomes an issue at higher speeds. A smaller wing cross-section infers a weaker wing, which also limits the lift a wing can generate.
A 10% hit in airspeed is worth a 50-70% gain in fuel efficiency. Don't expect to see this reflected in your ticket price;-)
Long, thin wingspans taking off from shorter runways makes me think it's considerably slower.
However, TFA says it could replace the overseas market, so the range must be there. If it carries the same amount of fuel as a 777, it must fly faster than 30% of the speed of a 777;-)
Those companies already mark-up business-class PCs. What will keep them from continuing to do so in the future?
Compare a business-class graphics card to a gaming card. I have no idea what the differences are (more pipelines, less memory, I have no clue, but I need it for 3D modeling, apparently). 4-year-old cards still go for +$300. Try to pull that off in gamer-land:-)
Basically what I'm trying to say is that businesses have always been willing to pay a premium for a more reliable box, and I don't see that changing in the future. My company did the whole server-run CAD programs a long time ago - my boss refers to his tower of old client boxes his "$40,000 plant stand"
Wasn't coming down on Obama either way on this one. I agree that you can't tally promises until after the current administration is out. I was just making the point that numbers can be skewed to make whatever point you want.
I also think saying that he's kept 110/163 = 67% of his promises is also dishonest.
And yes, on his inauguration day, he hadn't done anything, so he hadn't kept any of his promises yet.
I'm sure the guy is looking for a government grant, to study this intriguing possibility. Great job, if you can get it: spend government money to study if aliens are busy playing videogames
The best way to study would be to find the aliens and study directly. Send out the probes!
More. The answer is almost always more. Even though cars are smaller now, federal crash laws make cars heavier than back in the day.
That 1974 Pontiac would have had 1st generation federal mandate bumpers. Curb weight for a 1974 GTO (350ci V8) was 3486lb.
Smaller 2002 Concorde Curb Weight: 3487lb
Less displacement doing near equivalent work: that's called progress. The 1974 probably has more snot, but you're not looking for snot when you're looking for mpg.
In our business, it's called a "Time and Materials" project. Keep throwing money until the buyer gets a finished project, or they run out of money.
For projects like this, they probably set up contracts to do the engineering and development to manufacture with a promise of a minimum quantity of product ordered once finished. Cutting the contract at this point should just be a simple matter of paying the contractor for the work already accomplished and NASA getting any drawings, models or work produced in exchange (if specified in the original contract).
The sticky question is defining how much work was done and how much will be paid out to these companies.
As long as your game doesn't run the first few versions of DirectX you should be fine:-)
I had FF7 and 8 for the PC. They used weird DirectX drivers that have since been retired. There are hacks available to bring them up to current though.
You mean how my state's governor promised college educations to all of the public school students who maintained a B average? Yeah, and they just reneged.
"Hey Mr. Scott, what you gonna do? What you gonna do to make our dreams come true?"

grandparent is referring to Toe-in. You need some to keep the car stable, but excessive toe-in will create tire wear.
Some cars that are going to be constantly side-loaded (Nascar, for example) will run negative camber to improve tire contact in turns.
Under normal driving conditions, loading one sidewall more than another could lead to premature failure of the tires.
You obviously don't live in Chicago.

It is crap because it was weird and drivers were hard to come by. It is based on Windows Server, if I remember correctly...
Tuner quality matters too. Different TVs using the same antenna in the same place have different results too.
My parent's new HDTV loses signal on most channels when a bus rumbles by their street. They live in the city within 15mi of the transmission antennae.

NASA's link says the 777 design flies 10% slower. A pretty good return!

Have you tried running DirectX 1 and 2 games on new systems?

It doesn't work. You're at the mercy of hobby fixes.

Promises kept - 110/504 = 21%
Promises broken - 19/504 = 3.8%
Promises "not kept" - 394/504 = 79%
It's all a matter of perspective - which side of the aisle you're looking from.

Maybe if they put a higher curvature on it.
The immersion is supposed to occur because you can see more to the sides. If the side views are not in my periphery, isn't the effect lost?
