A Hand-Powered Table Saw Offers Electricity



Summary
A new hand cranked saw called the Jointmaker was found by Keith Johnston. This saw ruins only on your hand power and no gas or electricity. It will cut just as good as any other table saw too. One downfall is it costs $1,295. It is a hybrid device, a hand saw that employs custom Japanese saw blades offered in crosscut and rip grinds. The blade moves up and down via a hand-crank on the front of the machine and features an independent pitch adjustor. This combination allows for perfect crosscuts up to six inches in width and in material up to 1-3/4" thick.
Opinion
I think that this is a great idea. It is really a good tool for the “do it yourselfer”. Another thing is there is no pollutants from it. Without any fuel to power it, besides your hand, you won’t have to pay for anything extra. Also it’s not even like your downsizing you still great a great cut. I know I would get one.
Questions
1) Why does it cost so much?
2) Is the price worth it?
3) Would you get one?
4) Do you think it is a good step in renewable resources?

Seawater Acts as Fuel

US Navy Jet Taking Off

Wyatt Graves Summery,

March 15, 2010 the navy had finally completed their task to turn seawater into Jet Fuel. Engineers from the U.S navy have beeen working dligently to create a new scource of fuel for their jets and came up with an alternative fuel scource, seawater! This process involves "taking seawater and inducing a chemical reaction to extract carbon dioxide from the water and combine it with hydrogen. Afterward, the researcher is left with short-chain hydrocarbons which can be further refined into jet fuel." This discovery could change the way we power our jets in the future if we can disover a way to do it without the use of fossil fuels. This process consumes more energy then it provides; but puts us one step closer to turning off of fossill fuels.

My Opinion:
                     I think that it is great that the U.S army is researching new ways to power our Jets. If they spend enough time refining the process in which doesn't use fossil fuels then maybe they could end the dependance on fossil fuels for the world. Scientists took years to create this process and it is only a matter of time untill they make it a whole lot better and Maybe end the worlds dependance on oil and other fossil fuels.

My questions...

1. When did this project begin?

2. Who developed the plan for this project?

3. Are other Armies helping the U.S with this research?

4. Are there any other ways to fuel jets without the use of fossil fuels?

5. How many aircrafts have been built to use this fuel.?

Bug Excrement for energy.

Summary;
Some scientists who have been faced with the problem of energy usage and replenishing have been working on altering the DNA of bugs and insects, to try to get them to excrete oil, or at least something that is molecularly similar to crude oil. Normally, insects excrete some of their fatty acids, but with the help of genetic engineering, it is now possible to change that to a crude oil that is pretty much ready for the pump. And now, it only takes a few weeks and $20,000, compared to before, when it took several months of work and hundreds of thousands of dollars to accomplish the same thing. The inventors working on this "Oil2.0" are imagining it as being both renewable and carbon negative, so it will take more carbon out of the atmosphere than it puts in, kind of like celery and it's negative calories. Not only that, these organisms don't rely on any single food source, just anything that's available. This means that any argument of using specific food crops is going headfirst out the window. This idea was first put out in June of 2008, when LS9, the company that is working on the whole thing, could produce about one barrel of oil per week. To this day, they are still improving the machine used for that, and are trying to make it take up less space and produce more usable oil.

Opinion;
Finally! Another way to get energy without causing any harm to the atmosphere. What makes it even better is that the new solution can be used as oil, so cars with oil usage still have a chance at survival. What I can't help thinking of, though, is what the downside will be. Most methods have at least one. As I write that, I realize that of course that the insects are getting harmed, -ish. Since they now spew oil instead of fat, if too much of that gets into a body of water, we'll be back to the BP oil spill- again. God help us if that happens. And scientists are still working on it. But it can't be too much longer until they come out with a new machine that will produce more oil and take up less space. and that will completely change the way we use oil.

Questions;
1. What do you think could happen if we start taking insect excretes for energy?
2. What will happen to the other renewable methods of getting energy if we start to use this more often?
3. Could this have any negative affect on the ecosystem known as Earth?
4. How many people would you guess would choose to scare bugs into excreting oil, then putting it in their car? Or in a factory?
5. Should the EPA and other environment agencies put more money into this project, since it will inevitably affect the environment in both positive and negative ways?
