Definitely impressive. Actually, I was contacted by those guys last week and I'm going to be doing a detailed article about it.

Recent news states that a new idea for fire depts trying to extinguish ev fires is………., wait for it……., throwing a wet blanket over the entire car to attempt to smother it!
True story!
BTW, the 200 hp gas OB that holds those records, does weigh 65 lbs.
But to be clear, I am fan of the technology, especially seeing the school kids do it.
Way cool.
So far though, w/the ev stuff, it always seems they don’t share the whole story.
Yrs back while still in Fla, I went to a test n tune at Morroso Raceway.
Was a tech class teacher there running a 944 Porsche that his class converted to electric.
It was fast!
Mid 10’s I think.
I was all in on the thing.
Told the teacher how impressed I was.
Then I asked him about charging ��
Can’t remember if it was every pass or every other but…., the front half of his trailer had a 4 banger Pinto motor mounted to a generator to power his battery charger!
I grabbed another beer and went back to my lawn chair.
Chaz’s head would have exploded!
Give me noisy gas powered engine any day, not a lying Biden electric motor.
Chaz = thinkin .. if they didn't hold their ears, it would be their ear drums that would have exploded .. ;)Quote:

Sub 9 sec. Car from the factory

and it takes corners, try that with a rail bird
Doesn't BMW do that currently with their ICE cars? At any rate, what a cool project for these kids to get into. There's a bunch of youngins around me with bare bones EV retrofitted Hondas, Nissan's, etc. Not to mention the kids on the E bikes. My old ass was peddling down the 101 in Encinitas, and a squad of em came by me pulling mile long wheelies, lol. Don't matter the propulsion/ vehicle, seeing the younger generation hot rodding is cool AF IMO.Quote:

Like it or loath it electric power is going to be developed further for marine propulsion in the short term. Mercury is already supplying a 150kw complete electric race motor so let’s see if that survives longer than Seven Marine after Volvos purchase.
The boys across the pond are trying stuff too….

Ya'll let me know when its ready. It needs to get me & 3 passengers (plus crap) in my XB2003 up river 15 miles & back plus a few passes at 85-100 by the beach to show off a couple times. When it's ready let me know what dealer I can pick it up at. Thanks. RR
Yes Scott that is exactly what I was referring to.Quote:

No matter how you slice it, that is impressive. I'll have an article up soon with some details about the boat, but in the meantime, I'll just say that these guys are going to keep pushing for more speed. I think that is an addiction we can all relate to. :)
So that’s something slightly different. The idea here was can you take an existing midsection, gearbox and cowling and convert it to electric using used recycled automotive hardware and battery pack components freely available on the inter web. Still early days but looks promising and despite concerns from officials it’s managed a few runs without catching fire or electrocuting anyone.Quote:

The motor and speed controller was designed by Flux Marine, and it is a custom setup for this particular boat. They had tested it at 300 volts and determined that running at 400 volts was ideal. The batteries are lithium-ion, which makes perfect sense due to their capacity and relative light weight. I think it would be most interesting to see how it would perform using lithium-polymer batteries. Without a driver, the boat weighs in around 800 pounds, which is impressive. Interestingly, the boat has a closed-loop cooling system.
They're using a Speedmaster lower unit running in an overdriven configuration, which is really interesting. I'll have a lot more details here soon. :)
