Solar Electic Cars are the Future
The potential for electric cars to transform transportation around the world and here in the US is huge. Several factors need to be improved for this to really take off. The first is battery life. Yet, as I mentioned in a previous post, liquid batteries seem to have the potential for dramatically increasing the charge they can hold. What's important to remember is 80% of people drive less than 20 miles a day, and even the most conservative electric cars can travel 3 times that distance. If liquid batteries can be integrated into cars, the potential for 200-300 miles per charge seems reasonable, which is about the same as gas now. The difference however is electricity is a lot cheaper than gas, at 2 cents per mile. At current prices ($2.15/gallon), that's equivalent to 107mpg. When and if prices get to $4.00/gallon again, that price/performance increase to 200mpg! What's also nice about electric cars is they do not require a major infrastructure overhaul to get them on the roads. There are already electric outlets everywhere, and offering rapid charges at gas stations would be a minimal investment. At this point any research or development on biofuels is both economically and morally bankrupt, as the miles traveled per acre of energy generation use for solar vastly outstrips any biofuel alternative (see comparison chart below):
Continuing to use valuable arable land to grow fuel instead of food is unethical and in the increasing opinion of many, genocide, as it prices food out of the reach of the world's poor.
Generating electricity from solar for cars is both the economic and ethically right thing to do.
In the meantime, I'd like to point out two new entries in both solar and electric cars.
The first is Aptera's 2e, which goes 100 miles on a charge:
Some people think it's ugly, but I think it's beautiful. So apparently does the production staff for the new Star Trek Movie, which will feature the car in one of it's scenes. This car is a 2-seater with room for 15 grocery bags. Not bad for a commuter vehicle, and at 100 miles per charge, could account for more than 90% of the vehicals on the road today. Add liquid batteries, and electric cars would match gas for miles on a "fill", and be several times cheaper per mile.
The next car I'd like to talk is entirely solar car called Eleanor, generating ALL of it's electricity from it's surface using the sun, and it can go 90mph! Built by our lovely MIT team below:
Of course it's small, and exclusive designed to win the annual Australian 2000 mile World Solar Challenge, but think about this for a moment. A car that, as long as the sun is out, travel continuously without stopping, and obtain speeds in excess of 90mph at the same time. This to me is absolutely astounding, and straight out of the future! The only problems that I see with it (for the moment), are design issues to modify it for holding more passengers, and stronger materials to meet mandated safety standards. But add emerging carbon-based nanomaterials, with strengths 10 times stronger than steel, problem solved. Add compact liquid batteries, and no more need for eclectic grids, or charging stations. A Solar Electric Car that can travel non-stop during daylight hours, and if it's not traveling, stores all of it's solar energy while it sits, and available for you to drive at night. This would be THE solution to nearly all of our ground personal transportation needs indefinitely.

The solar is the future. There is a way to keep a smaller battery fully charged at night, using an extremely efficient generator powered by a constant speed fuel powered engine with as close to zero emmissions as possible. Also, recovering the energy from braking through flywheel momentum as a storeage medium to power thr generator is an option. I look foreward to watching the changes that are coming.

Very nice site! cheap viagra
Very nice site!
Excuse me. When I came back to Dublin I was courtmartialed in my absence and sentenced to death in my absence, so I said they could shoot me in my absence. Help me! I can not find sites on the: Cyberlaw united nations distance education. I found only this - distance education nursing. About investigators other of the amazing managing, it would apologize denoting for the disabilities of those range would more totally be recorded son down than information. Lot said a particular intro about millions children, blog ", and positive reason. Thanks :-). Lasca from Mali.
Hi guys. We thought, because we had power, we had wisdom.
I am from Guinea and also am speaking English, please tell me right I wrote the following sentence: "Flovent, message is a diarrhea husband patient and this seasonal and nasal tendency is using all of those tubing it to get it, as no easy powder can."

I am definitely bookmarking this page and sharing it with my friends.
:)
Very great website.
The information here is very important.
I will give it to my friends.
Cheers
I am the kind of guy who loves to try recent things. Currently I am making my personal solar panels. I'm making it all by myself without the help of my staff. I am utilizing the internet as the only path to acheive this. I saw a truly amazing website which explains how to contruct solar panels and wind generators. The place explains all the steps required to solar panel construction.
I am not really sure about how accurate the information given there iz. If some guys over here who had xp with these works can have a see and give your feedback in the page it would be great and I'd really value it, because I truly enjoy solar panel construction.
Tnx for reading this. You people are great.
Very nice Blog, I will tell my friends about it.
Thanks
Very nice Blog, I will tell my friends about it.
Thanks
This is a fervid blog and I capture desire reading it every morning show one's gratitude you

Very useful article. I am sure a lot of people will benefit from it. Thanks!
I do truly like your supreme topic! Could you create the term paper titles as example? Because I do really know that a professional paper writing service could compose custom research papers of brilliant quality.
I want to thank the blogger very much not only for this post but also for his all previous efforts. I found www.astranaut.org to be extremely interesting. I will be coming back to www.astranaut.org for more information.
Very nice site! is it yours too

Very nice site!
Hi,I specifically came across to you place from yahoo and I found you place very remarkable.
I chance, i can effect lot's of fresh lonesome now.
I absolutely agree with every word the author has written in this article!
It's really great to see students get into eco-friendly practices and development of such technology at such an early age.
С наступающим праздником Пасхи!!!
У Вас хороший ресурс, а у меня всё не хватает времени за своим следить(((

Nice post, thanks for writing!

Hello. This is kind of an "unconventional" question , but have other visitors asked you how get the menu bar to look like you've got it? I also have a blog and am really looking to alter around the theme, however am scared to death to mess with it for fear of the search engines punishing me. I am very new to all of this ...so i am just not positive exactly how to try to to it all yet. I'll just keep working on it one day at a time
