it is a little reactive, so recycling would need some special handling.
A little reactive? It would burn pretty violently if simply exposed to air, and EXPLODE if it came in contact with water. And either event would produce highly corrosive byproducts.
If NASA wanted to continue flying the shuttle until the Ares is operational, they would need a MASSIVE budget increase to build a parallel infrastructure.
The shuttle needs to retire so that the existing launchpads, crawlers, service structures, assembly buildings, control rooms, etc. can all be rebuilt/upgraded/revamped to handle the new launch vehicles. If they were to keep the shuttle flying, all that infrastructure would need to be built from scratch for the new program, and the existing facilities would then be useless when the shuttle was finally retired.
No, but it is Obama's fault for targeting an agency that represents about 0.6% of the national budget, when there are so many bigger wastes of money to go after.
The amount of money he is talking about would make a HUGE dent in NASA's ability to continue to the moon/mars/beyond, but would be like pissing in the ocean to the agency the funds will be given to (Dept. of Education).
for a lot more than the 4 years claimed by TFA, particularly if Obama gets elected and carries out his plans to slash NASA's budget.
And if NASA goes that long without manned spaceflight capability, the "brain drain" that will result will make it even more difficult to resume manned flights even WITH the political will to do so.
Every time I sit through the safety lecture on an airplane, hear anyone talk about "Jumbo Shrimp", or see someone prick their finger (but not finger their prick!), I'll think of him...

Using electricity directly for heating is very inefficient, whatever the source, and requires substantial upgrades to the distribution grid. The required upgrades to the distribution grid and individual home wiring would be the killer here.
But as far as efficiency goes, electric heating is 100% efficient. Every watt that gets consumed gets converted into heat. Even the IR losses in the building wiring help heat the structure.
Electric heating may not be economically competitive with gas or oil in all parts of the country, but that is not the same as efficiency.
"Strange that in this day or people trying so hard to be "green", that these same people don't demand that companies built products with such quality that they will last and not have to be replaced every other year." Probably because a huge percentage of what passes for "Green" these days has little to do with conserving finite resources, and plenty to do with slick marketing and making yuppies feel less guilty for their hyper-consumptive lifestyles.
Therefore, you get products made with "greener" materials which end up in landfills in a few years, rather than older technologies that were more rugged and able to be repaired. That way, the companies get to sell more crappy consumer electronics, and the consumers get to feel good about their "environmental consciousness" as they toss 3 year-old TV sets to the curb to buy new ones which are "even greener".
Semiconductors generally don't like high-radiation environments, such as outer space. Hence the normal use of specially made high-$$$ "rad-hard" components in space systems.
Schedules 2-5 are legal for anyone with a prescription.
Schedule I substances are "legal" in about the same way as weapons-grade plutonium is "legal". You need a special license from the DEA, which it will only grant to "legitimate research institutions" who agree to intrusive government inspections, endless paperwork, and accountability down to the last microgram for any drugs used. Criminal background checks for anyone who comes into contact with the drugs.
And that only allows you to use the drugs in a laboratory setting for forensic analysis or possibly in animals. If you wanted to do HUMAN testing (even for something as innocuous as pot), you'll need to go through several more layers of hell with the FDA, NIDA, NIH, and a few others, BEFORE you can apply for your DEA license.
And then the DEA can always yank your license on some bullshit pretense if they don't like the "sound" of your research results. That's just what they did with Dr. Shulgin after he published "PIHKAL".
They also invented and trademarked another well-known drug. It is technically known as diacetylmorphine, but you probably know it better under Bayer's tradename--HEROIN.
Pure Iodine is pretty much impossible to get nowadays, thanks to the War on Drugs (it is used in one popular method of making methamphetamine). The water purification kits have moved over to iodine compounds or other ingredients.
>>make sure the electrical is all properly grounded...
Good advice for MOST workshop applications, but if you are going to be working directly with line-powered electrical/electronic circuitry, what you actually want available is a completely ungrounded, isolated power source.
Standard AC mains power has one side (the "neutral") connected to earth ground at the main electrical panel. Therefore, the "hot" side of the powerline represents a shock hazard not only with respect to the neutral, but to every other grounded conductive object in the vicinity. By using an isolation transformer to feed outlets on an electronics test bench, you greatly reduce the potential shock hazard of working with line voltage, because you will need to get between the 2 sides of the powerline to receive a shock, rather than between one side of the line and any grounded object, concrete floor, water pipe, etc.
Using an isolation transformer also allows you to connect grounded test instruments like scopes and meters to your circuitry, without potentially creating a ground fault and vaporizing your test leads. If you will be testing "hot chassis" types of equipment like TVs, switching power supplies, etc., an isolation transformer is mandatory for safety.
Legos, model rockets, heathkits, and chemistry sets were all big influences (and my son and I STILL launch model rockets).
A good low-cost way to develop mechanical skills and encourage curiosity about how things work is a basic set of hand tools and a pile of discarded appliances/electronics. Let the kids tear them apart, and maybe even find out what failed. If you are lucky enough to get hold of older electronics (before VLSI/ASICs took over), you can even scrounge enough useful parts to build your own circuits.
I trashpicked TV's for years as a kid, and eventually taught myself enough about electronics to fix and resell most of them, earning enough money to buy my first real set of electronic test gear (mostly Heathkits),and land a summer job as a bench tech at a local TV repair shop while most of my peers were flipping burgers or delivering pizzas.

NASA has evaluated the DIRECT proposal, and found it lacking compared to the Ares I/V vehicles:

Why sell? Bunsen burners run on gas.
Alcohol lamps, of course, are another story....
Or drugs...

considering that one of Carlin's early albums was titled "Occupation:Foole".
Chalk up another one for the clueless mods...

Because at least here in the US, about the only people who use UTC are pilots and ham radio operators...

They also invented and trademarked another well-known drug. It is technically known as diacetylmorphine, but you probably know it better under Bayer's tradename--HEROIN.
It is listed in DEA schedule II. Truly illegal drugs (like heroin and pot)are Schedule I.
Methamphetamine is available on prescription under the brand name Desoxyn:
http://en.wikipedia.org/wiki/Desoxyn
put together with plenty of lead in the solder, right?
Now all they need are some counterfeit electrolytic caps puking their guts all over the windows for added effect.
Not to mention that the vast majority of funds spent on education come from the state and local level, not federal.
NASA doesn't get a chunk of your state or local taxes like your local schools do.
