'Child simple' 6-12 kW gravity generator prepping for market

Inventor Bobby Amarasingam of AOGFG expects that their 6-12 kilowatt power generator using gravity as the source will cost around $5,000 or less, be around 1.5 cubic meters in size, with production prototype being ready by early March.

On December 4, we reported that British "Inventor Bobby Amarasingam, is pushing ahead with his gravity motor technology, claiming test results, license agreements, manufacturing contracts, and customer contracts. Is it really possible to harness gravity? He says their recent 12 kW prototype testing was successful."

I've had a few chats with Bobby since then, and he has given me permission to report on some subsequent developments of his patent-pending technology and its rollout.

He said that with the 12 kilowatt test version they were able to prove the 1 to 96 ratio that had been predicted by one of the engineers from Rolls Royce (acting independently). He said it takes about 500 Watts to get it spinning, but once it is turning, it only takes about 50 Watts to keep it turning at 30 rpm, while it generates 12 kW. It's only about 1.5 meters cubed in size and runs very quietly – "almost as quiet as a refrigerator." The expected retail cost will be around $5,000 USD. That's less than $1 per Watt installed, which is 3-6 times cheaper than solar or wind.

Though the output can allegedly range from 6 kW to 12 kW, it's not dynamically load-following, as a typical household power system would require, so the first versions would be better suited to constant power output scenarios.

With the companies he has lined up presently in the manufacturing process, he expects that at latest by next March the first production prototypes will be done, going to market later in the year at a rate of around 100,000 units in the first year. One 6 kilowatt version will be cheaper, with a one year return on investment expected, with a down side that it will require a change out of the brushes on the generators. The other will be more expensive but ill be essentially maintenance free, with a 15-year warranty possible.

Then on December 26, he called and said that he had figured out a way to cut the cost by 75% by just combining the main shaft to a single generator, rather than having a generator at each carriage point in the Ferris wheel type arrangement. He said he built a mock-up to test the idea, and it worked. He said this is the 18th machine he's built.

Then on December 28, he left me a message saying that he had figured out a way to eliminate the drive motor so that the excess energy could be fed back to self power the system. He said it may take him a few days to build a mock-up to demonstrate that.

He said that there is no high-tech involved, but that it is a slight variation of existing technology, just put together in a novel way.

A group in Holland is doing the gears. A group in China is doing some of the manufacturing. And the main assembly and engineering is being done by a Dutch group.

On the 26th, he said a group of billionaires, under the instigation of the gentleman from Roll Royce, were going to be meeting to talk about how to support this technology to bring it into mass production.

He bemoans that he hasn't been able to get local groups in the UK interested in getting involved. Nor has he been able to get the BBC interested in giving it any coverage, though he's sent them material. He said he could show them working prototype, but they don't respond.

He said the reporter from ThisIsSomerset who first broke the story about this technology last September did a follow-up piece, but the paper wouldn't publish it.

The Dutch didn't believe it until they saw it, and realized it is "so simple".

With all the news about how much money the conventional renewable energy is costing, and how energy prices are going up, Bobby thinks it’s a travesty that his technology isn't getting more attention, given that it is both clean and cheap and easy to manufacture anywhere in the world, enabling distributed energy for the developing nations.

"They will spend $500 billion in research and development on some fusion technology, when there is a solution that is so simple – child simple. Such a waste."

He said that he has been financing this with his own money, without going into debt, selling some cars he had. One person offered him 60 million pounds to buy him out, but Bobby said it would be worth that much each year in royalties.

He plans on doing humanitarian work with the money he gets from selling these units. "10% for me, and the rest for humanitarian work."

Update from December 29; 7:30 AM MST

[Finished posting at 11:30 AM MST]

This morning, Bobby contacted me by Skype voice to tell me he stayed up until 2:00 am last night working on a mock-up on the self-run mode concept and was able to get far enough to show that it will work.  Now he just needs to find a machine shop open during the holidays to build a more robust version for demonstration purposes.  He said he only needs about four hours with a lathe machine, but he can't find anyone open or available.

In running some numbers, he expects that this design will be 20% more efficient and cost 70% less than the maintenance-free, 15-year warranty version mentioned above.  It doesn't require a drive motor, and it only entails one generator (unless several are ganged in parallel), and it could eliminate any gearing.  He is thinking that a 3 kW version could retail for $1500, and if mass produced, that price could go down to $750.  That is $0.25 per watt installed -- nearly 20 times cheaper than solar or wind, but with constant output capability.  But the licensees will be deciding on the price they actually charge, and they probably won't have the same outlook as Bobby in terms of providing energy at the lowest possible price.

The size of the unit required to make a certain amount of power will depend on the density of the weights used, which could range from lead and copper on the dense end, to cement or granite on the less dense end of the spectrum. 

He said that he spoke with the guys in Holland, and they are pushing forward with the previous design as planned.

I've been asking him for photos or video of the 12 kW version, but he said he's not ready to have that published yet.

ADVISORY: With any technology, you take a high risk to invest significant time or money unless (1) independent testing has thoroughly corroborated the technology, (2) the group involved has intellectual rights to the technology, and (3) the group has the ability to make a success of the endeavor.
All truth passes through three stages:
   First, it is ridiculed;
   Second, it is violently opposed; and
   Third, it is accepted as self-evident.
