After doing a bit of research it seems as if it is going to be in larger production some time next year:
+ Is GravityLight available to buy?
The new GravityLight model, GL02, is exclusively available through our Indiegogo campaign. Your support will also be helping us establish an assembly line in Kenya and start production in Spring 2016! NB. our first GravityLight design, GL01, was produced as a one-off batch of 7000, used in our global field trial and for the supporters of our first crowdfunding campaign.
It sounds like they are really onto something. Would you buy one of these?
It is this type of outside the box thinking that will lead to real scientific advancements!
Congrats to the team and we are rooting for them if it indeed is what they say.
Thanks to gravity light for the great info

This is awesome ..
That’s been made though its not something new
I came up with this idea 20 years ago..but who can afford a patent?…and trying to get funding when everyone thinks your crazy?
If we all went gravity energy efficient or whatever its called. Does that mean we have to pay a gravity tax to the government? They will find a way
Best watch your back! This is not acceptable. For those with greed. They will purchase the patient, and we
will never see true production. Just another failed good idea.
