George Johann Klein invented the electric-powered wheelchair in the 1950s. Considered as the most productive Canadian inventor of the 20th century, his other notable inventions include the microsurgical staple gun, the ZEEP nuclear reactor, the Canadarm, and the Weasel all terrain vehicle. Klein was working for the National Research Council of Canada when he came up with the electric wheelchair which was meant for injured World War II veterans.
In 2005, the first successfully working electric wheelchair was welcomed back to Canada during the official launch of Klein's biography in Ottawa. The chair had been given to the government of the United States in 1955 in a gesture to demonstrate the commitment of Canada to help disabled individuals all over the world. It is now displayed at the Canada Science and Technology Museum.
The electric wheelchair has been dubbed as Canada's Great Invention. Its development was spurred by the influx of veterans of the Second World War who had become disabled by injuries sustained in battle. The concerted efforts of the National Research Council of Canada, the Canadian Paraplegic Association, and Canada's Department of Veteran Affairs resulted in an electric motor propelled wheelchair that was actually useful.
Before the advent of this type of wheelchair, quadriplegics had no way to move around by themselves. A little earlier, Canadian Paraplegic Association founder John Counsel had successfully lobbied the Canadian Government for the mass purchase of manual wheelchairs. This helped paraplegic veterans but not quadriplegics. Dr. Klein, in collaboration with medical practitioners, patients, engineers, and scientists, then moved into the breach by originating the concept of the electronic wheelchair.
Born in Hamilton, Ontario, Canada on August 15, 1904, George Klein became an Officer of the Order of Canada in 1968 and was later inducted to the Canadian Science and Technology Museum Hall of Fame (in 1995) because of his work on the electric wheel chair and other noteworthy inventions. He died on November 4, 1992 in Ottawa at the age of 88 years.
His inventions, however, keep him alive in the memory of people all over the world, especially of those who are enjoying the independence and mobility that he made possible through the electric wheelchair. Today there are many adaptations of this kind of wheelchair, which has been customized to the different needs of individuals. Rear, centre, front wheel and four wheel drive variants are presently available.
Originally meant for quadriplegics and invalids who can not self-propel a manual wheelchair due to certain disabilities, the electric-powered wheelchair is now also prescribed for persons who have cardiovascular conditions. It can be designed for use indoors or outdoors, or for both. There are portable models and full featured "rehab" models. There are kinds that have on-board chargers while others have separate chargers.
The electric wheelchair is controlled by means of joysticks or other kinds of devices such as chin controls or puff/sip scanners. These controllers can regulate not only the chair's speed and direction but also other functional movements, such as recline, tilt, seat elevation, and leg elevation, that make its occupant able to perform certain motions and activities that would not have been possible otherwise.
It seems as though everywhere one looks, there is something being said about alternate energy sources. Be it fossil fuels, geothermal, wind energy, hydroelectric or solar energy, many homeowners are looking for ways to get more at a better rate. In fact, there is such an interest in finding a better energy option, that the solar market has increased in the US by 76% since 2012.
Perhaps one of the most commonly used forms of alternate energy is solar electric power. It has been used for decades in countries all around the globe and is effective at helping home and business owners lower their monthly energy costs - not to mention make them less reliant on area utility companies.
8 Reasons to Swap to Solar Electric Energy
If you are considering making the swap to solar electric energy, then here are some reasons you will want to do so:
Solar electric energy, contrary to what some might think, actually helps create jobs. In fact, the industry creates up to 3x more jobs than the coal or natural gas.
Independence from the power company. Once you have solar panels installed on your roof, you basically have an independent source of electricity and are not dependent on another entity.
Since you are not reliant on the power company, and you can count on the sun to rise and set each day, then you can be certain to always have an energy source. Consider this, 3,000 terawatts of solar energy shine down on the Earth's surface every day, which is 10,000 times the daily global energy use.
While the initial investment for solar electric energy can be a bit pricey, in the long run it can save you thousands of dollars. According to one study, it was found that homeowners who swapped to solar electric energy families saved more than $100 per month.
Solar energy does not require fuel combustion nor do you need to be concerned about gaseous emissions, thus minimizing your family's carbon footprint.
Because solar panels are installed on the rooftop, you are not losing any real estate in your yard or trying to figure out where in your home they can be placed.
They will last for up to 25 years and require minimal maintenance. After 25 years, the industry guarantees 80% performances.
There are a number of tax incentives available to homeowners who make the swap to renewable energy sources.
Swapping to solar electric energy is easier than ever before. If you are looking for a way to reduce your carbon footprint and save money while maintaining the needs of your family's energy source, then talk to a local sustainable energy provider to get started.

Cooking on an electric grill during warm summer months is an excellent option for people who do not want to cook indoors. Electric grills are also a great alternative for individuals who do not want to deal with the aggravation of having to refill propane or gas tanks, or who do not want a bag of charcoal on their balcony, patio, or in their garage. Furthermore, an electric grill is practically effortless to clean. These characteristics allow people to enjoy good food and great company without worrying about costly energy bills, having to run to the store for fuel, or taking time out of enjoyable conversation to clean a kitchen or traditional barbecue.
Preparing Electric Grills For Years Of Enjoyment
There are important preparation tips for first time buyers of electric grills. The most basic of these is the importance of seasoning your new purchase before you use it for the first time. Seasoning, also known as curing, entails filling the pores and voids in the metal with grease or oil of some sort. This oil subsequently becomes a part of the metal, which provides a smooth, non-stick surface. To begin, take a clean cloth, moisten it with cooking oil or grease, and rub it on the top side of the searing plates and all over the grates.
Next, plug the machine into any outlet, turn the switch on, and place the temperature to sear for approximately 15 minutes. This will incorporate the grease or oil into the metal. After the first 15 minutes, turn the dial up to the highest possible temperature for another 15 minutes to complete the process. For the best results, turn it off after the last phase and let it cool down completely. Now your electric grill is properly seasoned and ready to use.
Keeping Your Electric Grill Clean For Safe, Flavorful Food
A clean barbeque is the most effective method for guaranteeing safe, flavorful food. Electrical grills are a breeze to clean and maintain. For most models, all the user needs to do is remove the drip tray, dispose of the tray if the model is equipped with disposable pans or simply dispose of the waste in the trash bin, then place the cooking grate in the dishwasher. For an electric grill that is not equipped with dishwasher-safe cooking grates, simply remove the grates and wash them in warm, soapy water. Clean up is that easy.
Traditional barbecues require a lot more effort to clean. Take gas or propane grills for example; remove the cooking grates and place them in warm sudsy water for several minutes. While they are soaking, remove briquettes, lava rocks, or the metal flame shield to expose the burner. Gently remove ash or other residue from around the burner, and then use a stiff wire brush along with warm soapy water to lightly scrub the inside surfaces of the grill. After the grates are cleaned and re-installed, coat them and the rest of the inside surfaces with cooking oil or spray.
Charcoal or wood burning grills require even more effort. First, remove the grilling grates and any other loose items from inside the grill. Place the grates on newspaper, spray them with oven cleaner, and let them sit for a few hours to help dislodge grime for cleaning efforts later on. While you are waiting for the oven cleaner to do its work, remove ash and old coals from the grill and place them in the trash bin. After this has been completed, wipe down the inside of the grill with soapy water and a thick cloth. Who has time for all that maintenance?
Electric Grills For Everyday Use
Traditional grills have earned their place in American nostalgia. Most of us carry memories of spending time with our family and friends during warm summer months and want to duplicate the experience in our own homes. But replicating the experience in a manner that is quick and easy is most appealing.In addition,, what if one lives in an apartment or condominium where there is little outside space, or where propane or charcoal grills are not allowed? Electric grills are the perfect solution to these restrictions.
Many electric grill models are compact, portable, and do not require an open flame to cook food. Simply plug the unit into a standard electrical outlet, turn it on, and begin cooking. Not only do they cook the food, but several units include dual-heating elements that sear in juices and flavor while also leaving traditional grill marks that complete our vision of what barbecued food should look like once it is ready to eat.
Keeping your electric grill clean is one of the best ways to guarantee tasty, well-cooked food. This healthy habit will ensure a safe, germ-free surface to cook on and will allow food to retain its natural flavor rather than incorporating the tastes of a dozen past meals.
The electric car industry has had many false starts with the first one coming as early as the 1880s. To be exact, the first successfully built electric car hit the road in 1888, having come off a German manufacturing plant. Since then, several other attempts have been made over the course of history to bring these cars to the mass market to no avail. The current wave of excitement towards them began in 2008 and is likely to stay, considering how far the industry has gone in the last five years. All factors considered, it looks like these cars are finally breaking the "glass ceiling" to enter the mainstream automobile market.
These cars, as their name suggests are automobiles that are fully powered by electric energy. The energy is stored in a reserve (battery) from which it drives motor(s), which propel the automobile. Since electric energy is renewable, these cars have elicited quite some attention in recent years due to their ability to eliminate the emissions problem that is bedeviling environmental conservation efforts globally. It is common knowledge that motor vehicles are the biggest contributor to the emissions menace. As such, a shift from diesel and gasoline powered motor vehicles will no doubt cut global green house gas emissions by a massive margin.
This makes them one of the solutions to global warming and its devastating effects. At this point one would wonder why, if these cars have the potential to solve such a serious problem, they have not been adopted on large-scale basis. There are several answers to this question.
First off, their inability to travel long distances without interruption has been, by far, their biggest shortcoming. Since they are powered by energy from a battery, the capacity of the battery becomes an issue of interest. Up to recently, batteries could only store charge capable of powering an electric car for a distance of 90 kilometers at a time. This shortcoming led to what is commonly referred to as 'range anxiety' by electric car enthusiasts. The problem was further accentuated by the fact that charging infrastructure was largely lacking or underdeveloped in most parts of the world. Owning an electric car was, thus, impractical.
However, there is some good news! Tesla recently unveiled a new battery with a 315 mile range for use on these cars. This translates to 506.9 kilometers. Without doubt, this will effectively solve the range anxiety problem and make these cars more popular because most car owners, for example in the U.S., drive less than 40 miles per day. This, coupled with the fact that charging infrastructure and equipment are being established across the world, ensures that people will no longer worry about being stranded on the road when their batteries run out. To add to the good news, current batteries can charge much faster and more efficiently.
Another contributor to the struggling popularity of electric cars has been their prohibitive cost. Although today almost every major auto maker has its own model in this category, they still produce them on a small-scale basis, making the production very costly; costs that are liberally transferred to the buyer. The implication here is that even though some environmentally conscious individuals may want to own an electric car, they cannot a afford one that can meet their travel requirements. For example, the Tesla models fitted with the 315-mile capacity battery will cost between 134,500 USD and 135,500 USD. This price range is way above the means of the average car owner. It is, however, encouraging that since such improvements will bolster their popularity, this will lead to mass production and eventually, a reduction in costs.
These two have been the biggest obstacles for the electric car industry. However, since they are gradually being surmounted, the electric car industry is rearing to go. It is only a matter of time before they upset the status quo in the automotive industry. There have been claims of auto makers being prevailed upon by stakeholders in the oil industry to let go of their ambitions to populate the world's roads with electric cars. A classic example is GM's EV1. However, currently the world is past that stage and it can finally be said that electric cars will compete favorably in the auto market. So, yes! There is hope for the electric car industry.
