The Makita BFR550 – A Quick Review

Engineering

Power tools have evolved over the years, and one of the biggest changes happened when they became cordless. Just about every manufacturer, now has tools that can be powered by batteries. Makita tools are produced as good as any company, and thus one of those tools is the Makita BF550 Cordless Auto Feed Screwdriver. It is not just easy to use but it is very transportable. The screwdriver is actually so compact and lightweight, you will not even realize that you are carrying it.

The Makita BFR550 is a very long lasting screwdriver as it has a solid aluminum casing. It features a Li-ion 3.0AH electric battery that is significantly superior to their Ni-cd 2.0AH battery. The screwdriver’s MAKSTAR Charger allows it to control the power, temps and voltage which will prevent the device from over-heating. You will never worry about dead batteries with the Makita BFR550 since it can be charged anywhere.

It comes with a lock on button, so you don’t need to get up for another set of screws, instead it can continue to work without stopping. Labor can move much more rapidly with its reverse switch as well. You can also screw without jamming given that the Makita BFR550 has an anti-tilt option that will keep the screw from swaying. The stopper for your anti-tilt application has seven different options for the different screw sizes.

It will be possible to screw much more accurately because of its feeding line. You only need to press a button …

The Hydrogen Energy Cell Car – Back To The Future Or Today’s Reality?

Automotive

Probably one of the most important solutions to the planetary menace of global warming is alternative energy. Fuel cells, and particularly hydrogen fuel cells as a propellant for cars and trucks , is an demonstration of such an alternative energy type. You have probably never heard of it, since most people don’t know much about it. Many car makers are now trying to make use of hydrogen technology in the designs of their advanced cars. The by-product coming from hydrogen fuel cells isn’t harmful to the environment, especially given that oxygen is what is eliminated and all humans need oxygen.

Fuel cells as well as batteries are certainly not the same. Battery power can run down, while a fuel cell cannot. The power to run cars with fuel cells originates from the electrolysis process. In its basis, a fuel cell is just a pair of electrodes immersed in an electrolyte. During the entire whole process, the oxygen and hydrogen is actually separated, producing heat and water. The anode accumulates all of the hydrogen molecules, as the cathode gets all of the oxygen molecules. Natural gas, methanol or even gasoline can supply the hydrogen to be used by the fuel cell. The truly big difference making use of a hydrogen car is that it generates far less emissions than a conventional car.

The process generates a car which functions cleaner, and air which is not contaminated, because the process is essentially chemical, with no combustion taking place. The car is operated …
