In the future ...

Lately I have been reading and thinking about advances in technology.
In the future our MH will be much different especially in one area which is batteries. In searching the web I cam across a couple of things happening now.

"Toyota researchers are making steady progress in developing a battery that uses magnesium instead of lithium, and which could someday offer a cheaper and more energy-dense alternative.

Magnesium is an abundant material, so magnesium-ion batteries promise to be cheap. Such batteries should also have a higher storage capacity than lithium-ion ones because magnesium ions have a positive charge of two, rather than one for lithium ions. A magnesium-ion battery could store more charge per gram, and that would translate into a longer driving range in a car or running time for consumer electronics.

A company that is also actively pursuing magnesium-ion batteries is Pellion Technologies, which was spun out of MIT.

Lithium Batteries
"Jack Rickard from EVTV says this about the prismatic LiFePO4 cells:

"(Regarding electric cars) the news IS the batteries. Instead of 30 miles range (as with lead), we get 80-100 quite easily. And instead of 24 months, we can get 10 or 12 years from them. They are a miracle."

Jack has put these LiFePO4 cells in his DC conversion, with a motor from NetGain, and also in an AC conversion with a motor from HPEVS. Each system is getting 80-100 mile range. With lead, there would be a marked difference between the range he could get from his DC conversion (less!) and his AC conversion (more!) under normal driving conditions."

"You've probably heard that we don't really have NiMH EV batteries anymore. You can get NiMH batteries, but the large format NiMH that is suitable for electric cars is presently a patent hostage being held by Chevron."

Now electric cars have a range of 100+ miles on one charge. One person in the article talked about his homemade Toyota electric truck that has 100,000miles on his first set of on the batteries.

But the batteries are heavy and costly. As technology progresses and batteries become lighter and cheaper, we could be looking at a battery pack that would be needing charging only monthly. That pack could run everything in our MH and possibility eliminate the need for LP.Plus be lighter than present systems.

I may not live long enough to see it, but then again things can change quickly.

While battery tech moves forward, the real future is fuel cell.

These systems will have no range issues and will be very similar to fossil fuel vehicles where you fill a tank with hydrogen or similar - and go.

Hybrid systems will always use batteries, but pure battery powered vehicles will always be limited by charge time and range...and like stated above held hostage by the oil companies that want to keep the public on a leash to their fueling stations.

But that's just 1 man's opinion.

Interesting ideas.

I was thinking about running everything inside the MH on, say a 12 hr. charge once a month. I do not know enough to put the relationship of amp, watts, etc to figure to what is used by an electric car for 100 miles, to the amount of electricity that would instead be used to power MH electric heaters, electric stoves, electric hot water, electric refrigerators, etc. all converted to house current. This would be a no LP Motor Home with no need continuous recharging of the batteries. Even the generator as we know it would be an option.

With my limited knowledge it would seem that the energy used in an electric car for 100 miles could power the above for a good while.

The prototype batteries that were in the article, being more powerful, lighter and longer lasting would make a positive change to our experience and lighten our maintenance. These are what got me thinking about the value to the RV.

Now back to the future.
